2. General products description

InfiNet Wireless products offer scalable, robust, flexible and cost-effective broadband wireless access solutions for carrier-class networks. Wireless routing equipment from InfiNet Wireless is designed to implement and expand carrierclass networks for high-speed Internet access, enterprise campus networks, primary links for the Last Mile and backhauling traffic between cell towers and multiple access points.

InfiNet Wireless Devices are especially applicable to regions with complex wired infrastructures where infrastructure upgrades require costly or time-consuming activities. Many deployments have been accomplished in regions with a dearth of wired infrastructure where wireless solution is the only viable option for both voice and data networks. The deployment of InfiNet Wireless Devices minimizes both capital and operational investments for the creation of network infrastructure.

Key product features:

• Wide range of frequency bands

• Outstanding performance

• Powerful QoS capabilities

• Best-in-Industry networking feature set

• Flexible management

• Powerful integrated diagnostic tools

The InfiNet Wireless Devices can support flexible topologies including point-topoint links, point-to-multipoint links, MESH networks, high-speed transport connections (backbones) and relay-points building. They have been designed to prevent internal and external interference using such product features as software selectable transmit power control, static frequency selection, asymmetrical bit-rate/transmit power rates selection for base and subscriber units. In order to maintain link availability, solve the “hidden node” problem and reduce the collision rate, the product employs dynamic adaptive non-collision polling MAC protocol that dynamically redistributes data streams between active and inactive subscribers. Autobitrate mechanism is an optional powerful feature that provides link reliability in case of changing conditions on the path of the link.

The data network built on InfiNet Wireless products is implemented as a routed and switched IP network which reduces flooding and broadcast messages specific to bridged networks and to implementation of Quality-of-Service (QoS) features set. QoS definitions per subscriber’s data flows are effectively mapped on MAC level flow attributes.

Each device in the network can be configured using serial console port, Telnet protocol, WEB-interface and NMS system.

RAPS (Remote Access Permission Service) provides a whole network with a flexible mechanism of a centralized management, configuration and monitoring.

III.Installation procedure

1. Installation preparations

Required components and accessories

Before the installation, please make sure you have all necessary parts and accessories:

• InfiNet Wireless Device

• Antenna

• Low loss antenna cable for the required frequency range

• Antenna pole (if necessary)

• Required grounding system

• Accessories and tools

Antenna placement

When planning an antenna placement for PTP link, in order to obtain the maximal coverage range and best performance for the Device, one need to consider that LOS requirements must be fulfilled for the path between two antennas. Moreover, it is of vital importance that the certain zone that surrounds the signal propagation path must be free from obstructions. One should understand that the radio beam is not as thin as, for example, laser beam. Radio beam, also called as a 1st Fresnel zone, has a profile of a rugby ball. Its exact form and size depend upon the frequency and the signal propagation path length.

If most of the 1st Fresnel zone is obstructed, a major part of a electromagnetic energy will be lost which leads to a severe signal quality degradation and, as a result, to coverage range decreasing.

Below is an incomplete list of possible obstructions on the signal propagation path:

• Neighboring buildings

• Trees

• Bridges

• Power lines

To obtain the best results, it is necessary to perform a precise analysis of a signal propagation path zone and possible obstructions that may cover a part of the 1st Fresnel zone (usually the analysis is performed at the highest points of the signal propagation path).

When planning the antenna placement for Point-to-Multipoint connections, one must consider the necessity of a circular or sector coverage areas. In this respect, it is not recommended to use omni-directional antennas when sector antennas can be used.

While planning, it is strongly recommended to consult high-qualified

and experienced technicians

Page 26

InfiNet Wireless R5000 Technical User Manual

General recommendation for antennas placement are the following:

• Install antennas as high as possible over specific level. In case of flat surface - it will be ground level, in case of vegetation and forest – it will be tree heights, in urban environment – it will be the highest building in the observed area (specific level definition).

• Avoid tree and vegetation along with wave propagation path, influence of trees can increase depending on seasons (ice, dew, leaves);

• Proximity of other antennas should be avoided (at least 2 meters);

• Reflecting surfaces should be considered (building with reflective

windows, water surfaces or wet grounds);

• When installing antenna over water surface, one should tune height bracket within 1-3 meter range variation, because it can yield signal level variation from minimum to maximum.

• If seasonal changes influence on the signal quality, so then the most probable reasons would be either the connectors are not protected enough from humidity, summer vegetation or ice covered cabling and connectors during winter.

Antenna poles usage

Antenna installation is performed on a special facility called antenna pole. The pole is used for strong antenna tightening at the installation site. Poles might have different modifications depending on the installation requirements.

Poles with Stretching

Usually this kind of poles are used when installing antenna on a flat surface and permits one to raise it to a significant height for providing optimal conditions for signal propagation.

Wall Mounted Pole

Usually these kinds of poles are used when there is no need to elevate antenna to the rooftop and there is the possibility to mounting it on a wall. This installation is significantly simpler than that implementation with poles. Mostly it is used for subscriber side deployments.

Antenna Poles Requirements

Ease of antenna mounting and sufficient mechanical durability should provide reliable fastening in conditions of high windy loads. Poles should have round profile for ease of azimuth adjustment. Typical pole diameter is 30 to 50 mm.

Grounding

Antenna should be placed on the mast on the level that is at least 1 meter lower than a mast’s top. In this case it is of big probability that the lightning strikes the mast and not the antenna. The mast is to be grounded on the grounding contour according to your local standards. When the lightning strikes the antenna, the current goes through the coaxial cable which grounds ODU clamp with the mast – the mast is grounded via the grounding contour. The direct lightning strike to the STP service cable (ODU-IDU) is partially terminated on the grounded IDU case. Partial termination means that the direct lightning strike will probably destroy an STP cable. The service cable pickups from the electromagnetic

Page 27

InfiNet Wireless R5000 Technical User Manual

impulses are terminated on the IDU case by the winding shield, and further – on the IDU grounding.

The end of the STP service cable that is connected to IDU should be

assembled with a Shielded RJ-45 connector. The other end of the STP service cable (connected to ODU) should be assembled with unshielded (standard) RJ-45 connector.

IDU is grounded via a three-conductor power cord and a plug containing a ground. The data & power wires pickups are terminated via IDU protection scheme (three-conductor power cord and a plug containing a ground).

ODU grounding contour are connected with 100kOhm resistor, and that provides no static charge accumulation on the ODU case if there are some problems with its connection to the grounding contour.

Antenna pole, tower, ODU and lightning arrestor should be connected

to the first common grounding contour. Cable thickness should be no less than 10AWG using corrosion-steady connectors. IDU should be grounded to the same contour as customer LAN, having the second common grounding contour.

A special attention should be paid if antenna used is not DC-shorted. In this case additional lightning arrestor should be used between the antenna and ODU. Suggested grounding diagram is shown on the picture below.

Page 28

InfiNet Wireless R5000 Technical User Manual

Grounding when using IDU-LA

Antenna must be placed on the mast on the level that is at least 1 meter lower than a mast’s top. In this case it is of big probability that the lightning strikes the mast and not the antenna. The mast is to be grounded on the grounding contour according to your local standards. When the lightning strikes the antenna, the current goes through the coaxial cable which grounds ODU clamp with the mast – the mast is grounded via the grounding contour. The direct lightning strike to the STP service cable (ODU-IDU) is partially terminated on the grounded IDU case. Partial termination means that the direct lightning strike will probably destroy an STP cable. The service cable pickups from the electromagnetic impulses are terminated on the IDU case by the winding shield, and further – on the grounding contour.

The end of the STP service cable that is connected to IDU should be

assembled with a Shielded RJ-45 connector. The other end of the STP service cable (connected to ODU) should be assembled with unshielded (standard) RJ-45 connector.

The data & power wires pickups are terminated via IDU protection scheme (discharger and additional air gap). ODU and IDU grounding contours are connected with 100kOhm resistor, and that provides no static charge accumulation on the ODU case if there are some problems with its connection to the grounding contour.

Antenna pole, tower, ODU and lightning arrestor must be connected

to the first common grounding contour. Cable thickness must be not less than 10AWG using corrosion-steady connectors. Grounding contour development must be done by the skilled personnel.

InfiNet Wireless R5000 Technical User Manual

Antenna alignment

To obtain maximal system performance antennas must be precisely aligned one towards another according to LOS requirements. General recommendations for antenna alignment are the following:

• Align antennas using optical equipment (binoculars, spyglass) accompanied by mobile phone actions coordination

• Use GPS receiver and area map

• Use build-in InfiNet Wireless Device features. These features allow

evaluating current channel/signal quality and perform precise antenna alignment

Omni-directional and sector antennas have a wide radiation diagram width, thus usually they either do not require a very precise alignment or it is just not necessary due to radio link requirements.

Antenna polarization must be taken into consideration while installation. In most cases omni-directional and sector antennas have a vertical polarization. Directional antennas can be installed either with vertical or horizontal polarization. Please check a corresponding labeling on the antenna and address to the antenna technical documentation.

Precaution measures

Before you start the installation please read this section very carefully. Antennas are installed on the roof tops or on the building walls. This work must

be accomplished only by personnel having special skills and experience in this area.

Page 30

InfiNet Wireless R5000 Technical User Manual

Antennas and cables are electric conductors. Incidental electrostatic strikes may occur during the system installation. This can lead to equipment damaging or may hurt the personnel. While installing or changing the elements of the antenna-feeder system one must make sure that open metal parts are temporarily grounded.

Do not install the antenna close to the electric power lines. Antenna and antenna pole have to be installed in such a way that while their assembling, disassembling and repairing they did not have any contact with power lines.

Basic precaution measures that must be fulfilled during the installation are the following:

• Do not stay on the roof top in windy or rainy weather, during the thunderstorm or when the working zone is covered with snow or ice

• Do not touch the antennas, antenna poles, cables and lighting arrestors during the thunderstorm

• Antenna placement should not be close to electric or telephone lines. Safe distance is a distance that is a sum of the two antenna poles heights and antenna height

• Antenna cable must be grounded at all times (not relevant for 5000-M modifications)

In case of failure any manipulations with the equipment are allowed

to skilled personnel only.

Use RJ-45 connector without grounding here (RJ-45 connector with grounding is used for connecting service cable to IDU).

Step 2. Stick rubber filler – 5 on the Part 4, previously having removed protective white layer from rubber filler -5.

Insert Part 2 inside part 4 up to the stop. Part 2 must be entirely within Part 4.

Step 3. Put connector parts on the STP service cable as shown.

Attach RJ-45 connector without grounding to the STP service cable according to the “RJ-45” soldering scheme (in the “Supplementary information” chapter of this manual) and crimp the connector using a crimp tool.

Please tightly crimp the RJ-45

connector. Not crimped or badly crimped connector damages the unit when assembled into it which is not considered as a warranty case.

Step 4. Put Part 4 on the attached in the previous step RJ-45 connector.

Step 5. Screw Part 2 on Part 4. This fixes the “RJ-45” connector on the cable. Check that the connector is properly fixed on the cable.

Step 6. Assemble the connector to the unit.

Step 7. Fix the connector by screwing Part 3.

Now the connector is hermetically attached to the unit.

IV.Basic configuration instructions

1. Initial settings configuration procedure

Before starting new device, one should perform initial configuration. The configuration can be performed either using serial console port or using Telnet protocol. In order to configure the device using Console port, follow the instructions below:

• Device should be connected with host serial interface, using InfiNet

Console cable

• Start any terminal emulation software (e.g. Hyper Terminal)

• Set serial interface properties to 38400 baud rate, 8 bit, 1 stop bit, parity

off, flow control disabled

• Enable emulation mode ANSI or VT100, keyboard VT100

To connect using Telnet protocol from the wired LAN run Telnet with 10.10.10.1 IP-address that is configured for the Ethernet interface of the device by default.

If all above procedures are completed correctly, you will see the WanFlex OS prompt:

Every new device has no initial login and password settings, so you can use any non-zero length login and password to enter the device:

After default authorization there will be standard console prompt:

console>

Now the device is ready for the initial configuration procedure. The most relevant thing to be done at this phase is to define device name/user/password.

system name Test Base Station system user root system password qwerty

Part of commands in bold must be typed in CLI (Command Line

Interface). The rest of the command name is optional and can be skipped while typing.

Since this is made ONLY specified username and password can be used to access the device. DO NOT FORGET THESE PARAMETERS.

2. Device interfaces

The Device has several physical and logical interfaces:

• lo0 - loopback interface, used for system interaction needs

• null0 – logical interface, can be used for auxiliary addresses assignation

(for NAT module, for example); for routes aggregation for RIP protocol. Addresses (subnets) are announced to the network but every packet transmitted through this interface is destroyed

• eth0 - Ethernet 10/100 Mbit interface

Page 43

InfiNet Wireless R5000 Technical User Manual

• rfX.0 - radio interfaces. See device’s labeling or use “ifconfig -a”

command to learn your radio interfaces

• wifi0 – Wi-Fi AP interface

• pppX – point-to-point interfaces

• tunX - interfaces used for IPIP tunnels building

• vlanX – interfaces supporting VLAN 802.1q tagging

All configured interfaces of the Device can be reviewed using the following command:

ifconfig -a

3. Command line interface (CLI)

For device’s management and configuration a Unix-like command line language is used. Every command starts having the power right after Enter key is pressed. However, each command lifetime duration is limited within one configuration session. In order to save a current configuration “config save” command is used.

Several commands can be grouped in one line using “;” character. If a wrong- syntax line is met in the group, the rest of the string is checked anyway and the wrong command is ignored. Command name can be shortened unless the ambiguity occurs.

If your terminal supports VT100 or ANSI standard you can move around the list of recently executed commands using cursor keys. Numbered list of these commands can be reviewed by “!h” command. Any command from this list can be available using “!<NUMBER>” command. TAB key performs substring search of recently executed commands.

Ctrl/R combination refreshes the command string if its content was disturbed by system messages.

The command executed with no arguments prints a short hint about its keys, parameters and syntax.

Context help can be obtained by printing “?” in any position of the line.

4. Lost password recovery

The system password can be recovered remotely. The procedure is the following:

1. Locate your device’s serial number (SN)

2. Send this SN to the InfiNet Wireless Technical Support

3. You will be given a special key

4. Enter the device and use SN as a login and received key as a password

5. Reconfigure the username and password

Lost password recovery using Emergency Repair Console: Recovery procedure can be done with the help of “erp” command or graphical

“ERConsole” utility. Below is a description of “ERConsole” utility recovery procedure (“erp” command

recovery procedure is described in “OS WANFleX User Manual”):

1. Connect a computer and a device that should be repaired to one physical

Ethernet segment.

Page 44

InfiNet Wireless R5000 Technical User Manual

It is recommended to put a switch between the unit and the PC from

which ERConsole is executed.

2. Start «ERConsole» utility on the computer by running “ERConsole.jar” file.

Utility will be running in a waiting mode.

3. Restart the device. During its restart «ERConsole» utility will determine the

device and will show necessary information about it in the “Discovered devices” section of the main window.

«ERConsole» utility main window.

4. Send “Serial” and “Sequence” field values to the InfiNet Wireless Technical Support.

5. You will be given a factory password for the device.

6. Press «+» button in the «Scheduled tasks» section of the main window.

7. In the opened “New task” window choose “Reset configuration” in the “Command” field. Then enter Serial number and factory password in the corresponding fields. Press «Ok».

Page 45

InfiNet Wireless R5000 Technical User Manual

«New task» window.

8. Restart the device.

After device restart “ERConsole” utility will reset device configuration to the default.

9. Now login the device with any non-zero length login and password.

10. Reconfigure device username and password.

The “ERConsole” utility’s “New task” window also allows setting the units’ IPaddress on its Ethernet interface (eth0) without login to the unit. To perform this procedure please follow the below steps:

1. Firstly, do steps 1-3 as described above.

2. Press «+» button in the «Scheduled tasks» section of the main window.

3. In the opened “New task” window choose “Up interface” in the “Command”

field. Then type the required IP-address and network mask in the corresponding fields of the window and press “Ok” button.

4. Restart the device.

After the restart the “ERConsole” utility will add the IP-address into its Ethernet interface configuration and will up the interface (in case it was configured “down”).

5. Configuration manipulations

Printing and saving your configuration

You can easily review your current device’s

configuration by executing

“config show” command. The output of the command is sorted by the configuration sections (e.g. “System parameters”, “Interfaces configuration” etc).

You can review some particular parts of the configuration specifying the part of the configuration you want to see.

Example:

config show ifc

This command will print the interfaces configuration. You can specify several parts of the configuration separating them with a space bar.

Example:

Page 46

InfiNet Wireless R5000 Technical User Manual

config show rip nat

In order to save your configuration “config save” command is used. It saves the current system configuration in the Device's flash memory for subsequent permanent use. All modifications to the system parameters, if not saved by this command, are valid only during the current session (until the system reset occurs).

Import/export

Export/import of the device’s configuration is performed using “config export” and “config import” commands correspondingly. “Config export” saves the Device configuration on a remote server and “config import” reloads it from a remote server. The information is transferred using FTP.

Example:

config export user:secret@192.168.1.1/var/conf/test.cfg

“Config import” command writes the uploaded file directly into the Flash memory without changing the active configuration in RAM. In order to make a new configuration active, right after “config import” command implementation finishes the device should be rebooted. If “config save” command is run before rebooting, Flash memory is overwritten by the copy of the active configuration. This action will erase the uploaded configuration file.

New firmware uploading

The latest firmware version can be downloaded from our support site (http://support.infinetwireless.com) and from our ftp-server (ftp://ftp.infinet.ru).

Command “flashnet” uploads specified firmware version to the Device. Download is performed using FTP and FTP server should be installed somewhere in the network or on a local host from where download being performed.

File name is a full path including IP address of FTP server:

flashnet get upgrade@192.168.1.1/conf/infinet/infinet_new.bin

Where 192.168.1.1 is IP-address of FTP server and .../conf/infinet/infinet_new.bin is a full path to firmware version.

The download process has two phases:

• File uploading into RAM of InfiNet device.

• Programming InfiNet device flash memory from RAM firmware image. This

phase is indicated by “O.O.O.O.O.O…” sequence.

Do not interrupt this process, otherwise device will be brought into

invalid state and it recovery will be possible only at manufacturer premises.

During installation process all system events should be observed in the system journal (command “sys log”).

6. IP address formats

Many commands of the operating system require specification of IP addresses. In OS WANFleX, the IP-addressees may be specified in traditional numeric

format. Optionally, the mask may be specified either by its bit length (the specified number of leading bits in the mask are set to 1, the remaining bits are

Page 47

InfiNet Wireless R5000 Technical User Manual

reset to 0) or numeric value. The IP address 0/0 denotes all possible IP addresses.

Therefore, the possible formats to specify IP-addresses are: nn.nn.nn.nn (no mask is used) nn.nn.nn.nn/N (N is the bit length of the mask) nn.nn.nn.nn:xxx.xxx.xxx.xxx (xxx.xxx.xxx.xxx is the numerical value of the

mask) Example: The 192.168.9.0/24 address describes the network address 192.168.9.0 and the

mask with leading 24 bits on. The same set of addresses may be denoted as 192.168.9.0:255.255.255.0.

7. Ethernet interface configuration

In the most basic form Ethernet interface can be configured as follows:

ifconfig eth0 1.1.1.1/24 up

UP flag means than the interface is turned to UP state. Also you can specify the following parameters for the Ethernet interface:

• Media type. By default media type is selected automatically (media

auto parameter).

• Assign aliases to the Ethernet interface (alias key word)

Full information about interfaces configuration can be reviewed in OS WanFleX User Guide – ifconfig command.

8. Radio interface configuration

Radio interface configuration is performed using “rfconfig” command. In its most basic form one need to configure the following parameters of the radio interface:

• Frequency (freq parameter) in MHz. For example, 5260.

• Bit-rate (bitr parameter). Bit transfer rate in kBits/sec.

• System identifier (SID parameter). A hexadecimal number in the range

of 1H to FFFFFFH. All Devices that are supposed to see each other on the same radio link must have the same identifier.

Radio interface state is not saved in the configuration. That means

that if you put radio interface to the down state after rebooting it will be in the up state.

Example:

rfconfig rf5.0 freq 5260 bitr 130000 sid 01010101

Additional important parameters and settings for the radio interface:

• Rf5.0 – radio interface name in this case. In order to obtain radio

interface name either see the ODU/Device

labeling or execute

“ifc -a” command.

• txpwr – transmitting power selection. Available power levels can be

obtained using “capabilities” parameter as shown above

• burst – enables burst mode. BURST protocol means grouping several

short packets with the same destination address on a radio link into larger packets, thus cardinally decreasing the response time for

Page 48

InfiNet Wireless R5000 Technical User Manual

applications generating streams of short packets. Burst enabling relates to a radio interface as a whole, and means only that you want to use this mode in this device; but the BURST protocol can only work for destinations where it is also enabled at the other end, and only if the MINT protocol is used at both sides.

Burst enabling does not induce any changes in the work of other devices in the network. To disable “burst” mode use “-burst” parameter in “rfconfig” command.

• distance: this parameter is used to set the exact distance value

between two devices (in kilometers). This parameter changes time values for some delays and time-outs of 802.11a/b/g protocol thus making possible to work on longer distances with smooth adjustment.

There are several ways to manage this parameter:

o if you set an exact value, this value is used no matter what the

connection method is used

o If the CPE has auto value instead of a number (by default), the

CPE will configure its parameters using Base Station commands. It is enough to set a numeric value on a Base Station (the distance to the remotest CPE); all other CPEs will automatically adjust their work. While configuration showing, there might be the current distance value after auto parameter: auto (XX)

o when knowing exact device's geographical coordinates (e.g.

using GPS) you can specify their values in “sys gpsxy” command and distance parameter set as auto on all devices including the Base Station. In this case devices will automatically adjust their settings selecting an optimal value for the distance parameter. Base Station will calculate a distance to the remotest subscriber, and subscriber will calculate a distance to the base station. If the CPE has a link coordinates information it will use this information, otherwise it will use the distance parameter value got from the base station.

o If distance parameter is set to 0 radio module will use default

settings.

• pwrctl – automatic transmitting power control mode. In this mode the

output power is set up automatically within the values available for the radio module. Used for CPE only.

Example:

rfconfig rf5.0 freq 5260 bitr 130000 sid 10203040 burst rfconfig rf5.0 txpwr 18 distance auto

To learn your device’s radio module capabilities type the command:

rfconfig <IF-NAME> capabilitites

<IF-NAME> - radio interface name. Can be read on the device’s labeling located on the case.

9. Wi-Fi AP interface configuration

Wi-Fi AP interface configuration is performed using “wifi” command. To learn available Wi-Fi AP interfaces on your device (for example, wifi0) type

the command:

ifconfig -a

Page 49

InfiNet Wireless R5000 Technical User Manual

Set proper IP address and net mask for Wi-Fi interface (“wifi0”) using “ifconfig” command. For Wi-Fi AP activation use “ifc wifi0 up” command.

Example:

ifc wifi0 10.1.1.1/24 ifc wifi0 up wifi wifi0 -freq 2432 –antenna diversity

Available “wifi” command options:

ssid <"string"> - sets network ID (Service Set Identity).

-freq <value> - sets central frequency in MHZ.

-txpwr <value> - sets AP output power in dBm.

-antenna <value> - sets active antenna for AP. In diversity mode AP will

choose antenna to use automatically for each subscriber depending on the link quality (only for APs with two Wi-Fi antennas).

-auth <string> - sets authentification type for subscriber connection.

-pass <”string”> - sets a password for subscriber authentification.

-wpa-encrypt <”string”> - sets traffic type for WPA-authentification.

Available “wifi” command parameters:

cap – shows AP capabilities. status – shows AP status. stations – shows AP’s subscribers information.

10.Network topology setup

At the core of the system is a MINT (Mesh Interconnection Networking Technology) protocol which acts as a topology defining architecture of InfiNet Wireless system. Please refer to the WANFleX OS User Guide for a detailed description of MINT protocol.

Page 50

InfiNet Wireless R5000 Technical User Manual

V. Link Configuring

1. Preliminary decisions

Bitrate selection

Overall link performance is greatly depends on the right bitrate selection. Wrong bitrate of a radio link in most cases lowers its performance characteristics. In the result subscribers are getting bad services.

IW MINT architecture makes bitrate selection process fully automatic. Using IW proprietary Link Forecasting and Active Testing algorithms MINT chooses the optimal radio transmission rate individually for each connected subscriber device.

• Therefore, main recommendations for bitrate selection are: enable autobitrate mechanism and set the maximal available bitrate on the radio interfaces of all the devices

• To estimate the real bitrate of the device prior to its installation and deployment use the Range Calculator utility (see below).

Frequency planning for multi-sectored Base Stations

Base Stations with six sectors deliver the maximal performance by providing with sector reciprocal reservation and best price/performance parameter value. When having an optimal frequency gap of 40 MHz between adjacent sectors of the BS, the following schemes are recommended to be configured (e.g. having 5 available in configuration frequencies F1, F2 … F5):

• F1, F3, F5, F1, F3, F5

• F1, F3, F1, F3, F1, F3

Transmitting power selection

High output power correlates with the maximal connection performance. Decreasing the output power is logical when the maximal bitrate is already reached and there are no repeats. In this case excessive output power can decrease the system parameters. When having no built-in or external amplifiers one can try to install the automatic power control for the subscriber.

Range|Bitrate calculation

Range/Bitrate calculator allows estimation of a bitrate and distance for a particular radio link. This calculator can be downloaded from “Repository” of our support web-site (http://support.infinetwireless.com).

Page 51

InfiNet Wireless R5000 Technical User Manual

Range/Bitrate calculator view.

To use the calculator:

1. Set needed frequency range in “Band” field.

2. Set NLOS parameters in “Path type” field.

3. Set radio channel width in “Bandwidth” field.

4. For Site 1 and Site 2 define device model, device’s max output, antenna gain and feeder loss.

5. Press “Calculate” button.

The results will be listed in a table below. For each available Bitrate value you will see corresponding distances in kilometers for “worst”, “mean” and “optimal” environment conditions.

Earth surface relief is not taken into account in calculations.

2. Link diagnostic tools

Ltest

Ltest utility allows precise test of a radio link. It is recommended for antenna alignment when installing a new device or for testing of existing radio link.

Ltest can work in standard, alignment and bandwidth modes.

Standard mode:

In standard mode Ltest measures signal levels, retries, lost packets and acks. To start Ltest in this mode:

Page 52

InfiNet Wireless R5000 Technical User Manual

lt rf5.0 <Mac-address of a device on the other side of the radio link>

When «ltest» command starts it will show you output information that contains testing results. You can see Ltest output below:

Current/Maximum

incoming signal

level

Current/Average

number of retries

in percent

Current/Average

number of undelivered

packets in percent

Current/Average

number of undelivered

acks in percent

Local device statistics

Remote device statistics

Estimated

round-trip time

For success radio link establishing the following factors have to be considered:

1. It is recommended to start antenna alignment with searching maximum

signal level on a minimal possible bitrate. Afterwards automatic MINT mechanisms will set the most appropriate bitrate if autobitrate mode will be enabled.

2. Current incoming signal level in «amp/max» columns (see “ltest” command output) must be between 12 and 40.

When it is more than 40 it is recommended to lower amplifier power. If maximal signal level is less than 12 it is recommended to lower bitrate

or channel width (for example, from 20MHz to 10MHz on the both sides of the radio link). In some cases signal level that is less than 12 may be enough for radio link operation. In this case one has to be guided by such parameters as number of retries, number of undelivered packets and number of undelivered acks. If the number of undelivered packets and the number of undelivered acks is null, the number of retries is small and all these parameters are constant in time then the radio link, most often, will be operating properly.

3. Number of retries value in «rt%» columns must be as close to zero as possible.

4. Number of undelivered packets value in «up%» columns must be zero; if this value is not zero then the radio link couldn’t be exploited.

Page 53

InfiNet Wireless R5000 Technical User Manual

5. Number of undelivered acks value in «ua%» columns must be zero; if this value is not zero then the radio link couldn’t be exploit. If this value is constantly not less then 50 then most probably «distance» parameter is set with a wrong value. If radio link distance is more than 20 km then «long» mode must be enabled.

ALL described parameters must be observed in the both (Local and Remote) sections of the «ltest» command output.

Alignment mode (for Xm-series only): The difference of this mode from the standard one is that «ant.amps» column is

used instead of «amp/max». «Ant.amps» column indicates signal levels for each of two antennas of a devce divided by “:” correspondingly.

To start Ltest in this mode:

lt rf5.0 <Mac-adress> -align [L,R]

Ltest output in alignment mode:

Bandwidth mode (Bandwidth meter): Bandwidth meter is used to test the following radio link characteristics:

throughput in kilobits per second, packets per second, number of retries and errors.

Use the following «ltest» command options for testing:

• -tu [seconds] – Unidirectional test: packets are transmitted only from the current side to the specified address (“target” option)

• -tb [seconds] – Bidirectional test: packets are transmitted in both directions

“Seconds” parameter allows setting test period (5 seconds by default). Maximum value is 60 seconds.

To start Ltest in this mode:

lt rf5.0 <Mac-adress> -tb

“Ltest” command output in Bandwidth meter mode:

Muffer

The muffer module makes it possible to rapidly test the electromagnetic environment, visually estimate the efficiency of the utilization of the air links, reveal sources of interference, and estimate their power.

Several operating regimes of the muffer module provide for different levels of details in test results

Review mode

This regime is enabled by the review option. It makes possible to have a general estimation of emissions and interference within specified frequency range.

Normal operation of the radio is not possible in this mode.

This regime can be useful on the first steps of link configuration. One can observe the activity on the selected list of frequencies and make decisions of what frequencies can be used for the link so that the link did not interfere with other sources of signals.

The scan is performed only for the packets corresponding with the

standard of the radio module (802.11a for 5GHz devices and 802.11b for 2.4 GHz devices. Other sources of signals on the scanned frequencies stay unseen.

The picture above shows the output of review mode. To run the review mode please type the following command:

muffer <IF-NAME> review

Page 55

InfiNet Wireless R5000 Technical User Manual

Once the link is established you can use this mode to review the activity on the configured for frequency for the link. If no activity is observed that means that the signal from the remote side is being broken by the interference sources or by the obstacles on the signal propagation path.

MAC2 mode

This regime performs MAC-addresses analysis to estimate the number of clients with different MAC addresses and the efficiency of their utilization of the air link. The analysis is carried out for all MAC addresses at the frequency previously specified by rfconfig command. The mac2 regime checks both data packets and the link-level ACK messages sent by protocol supported devices.

Normal operation of the radio is not possible in this mode.

The picture below shows the output mac2 regime.

Like in review mode this regime provides with the information about a current activity but on the configured frequency.

To run the review mode please type the following command:

The statistics gathering is used for estimating link load intensity and per client. The amount of packets sent and received, and the number of retransmissions is shown for each MAC address participating in the data exchange.

The statistics output is presented in the picture below.

Page 56

InfiNet Wireless R5000 Technical User Manual

The following decisions can be made by analyzing the outputted parameters:

• If the number of repeated packets is comparable with total number of packets that means that you might have an interference source on the selected frequency. For normally operating link the percentage of repeated packets should not exceed 10%. It is extremely important to obtain a permanent zero value for the average number of repeats per packet. If the value is not zero that means that the link is NOT working properly and requires further improvement

• If total percentage of repeated packets and the percentage of packets that were repeated at least once are close to each other that might mean that you have got a permanent source of interference. Otherwise, it means that a strong interference source appears from time to time breaking your signal

• Concerning the fact that statistics module outputs the information for each MAC-address separately, you can reveal the problem for some specific unit on the wireless network

The “muffer stat” command shows the statistics only from registered devices. To view statistics type the following command:

muffer stat

To reset all counters please type

muffer stat clear

Other modes of muffer

The muffer also has the following modes:

• mac mode. Compared to the mac2 mode this mode does not take link- level ACK messages sent by protocol support devices into account

• mynet mode performs the radio testing without disturbing radio module's normal operation, but taking into account only packets from within the given network

Page 57

InfiNet Wireless R5000 Technical User Manual

• sid mode. The sid regime allows estimating the number of currently operating subscriber groups having different identifiers (SID), and the efficiency of air links utilization. The analysis is carried out for all network identifiers at the frequency previously specified for the radio module by rfconfig command.

Load Meter

Load meter is a powerful tool that allows estimating the load of a system interface specified by interface parameter. By default, the information is displayed on one line and updated every second; the load is measured in kilobytes.

Below picture shows the load meter output for the radio interface outputted in line-by-line mode with one second interval.

To run load meter like it is shown above, please type:

loadm –l <IF-NAME>

Acquiring interfaces statistics

Interface statistics can be acquired using netstat module which includes two modes:

• Routing tables output (using “-r” parameter with the command)

• Interfaces statistics output (using “-i” parameter with the command)

Below picture shows the example of interfaces statistics output.

Page 58

InfiNet Wireless R5000 Technical User Manual

If the interface has several aliases the statistics is still measured for

physical interface in a whole. For example, see rf5.0 or eth0 interfaces above. The numbers shown in 4 right columns correspond in physical interface.

Constant lighting — diagnostic device-ODU connection established, diagnostic device power is normal. Blinking 1 time per second — diagnostic device power is normal, diagnostic device-ODU connection is not established. Blinking 4 times per second — diagnostic device-ODU connection established, diagnostic device power is low (change batteries). Frequent blinking with intervals — diagnostic device power is low, diagnostic device-ODU connection is not established.

2. Radio link LEDs

Show whether radio link is established on certain ODU’s radio interface.

Constant lighting — radio link is established. What ODU’s radio interface to show by what column RF0 or RF1 is chosen by the following

way: for RF0 column is taken radio interface with the least number, for RF1 the other interface. For example, there are the following radio interfaces on ODU: Rf5.0, rf5.1. Then for RF0 column rf5.0 will be taken, for RF1 — rf5.1.

When no radio link then LEDs 2-4 are not lighting.

Once the unit is wirelessly connected to the remote neighbor it is possible to make extended diagnostic and optimization of this link. To do this just mouseclick on the row containing data of the wireless link you want to test (as on the picture shown below):

Page 75

InfiNet Wireless R5000 Technical User Manual

Then choose “Antenna alignment tool” or “Performance tests” from the appeared “Extended Link Diagnostic” window.

Antenna alignment tool

Graphical antenna alignment tool visualize antenna alignment process making it quicker, easier and comfortable for the user.

“Antenna alignment tool” page view for “R5000-Xm” device models is shown below:

“Start Test”/”Stop Test” buttons at the bottom of the page start/stop the alignment test.

“Exit Test” button returns to the “Device Status” page. “Help” button displays help guidelines for antenna alignment. Once the test is started antenna alignment can be monitored using graphical and

text indicators. Indicators for both local and remote devices are displayed together on the same page that allows viewing the alignment process for both sides of the link.

Each side of the link (local and remote) has two similar test indicator sets corresponding to two antenna polarizations (rx chains) of the device (one for Vertical polarization and another for Horizontal). This allows controlling the alignment process for each antenna polarizations for local and remote devices simultaneously.

Text indicators are the following:

• Error Vector Magnitude (EVM) – indicator of the measured input signal

quality. It should be as high as possible. The recommended level is not less than 21.

Page 76

InfiNet Wireless R5000 Technical User Manual

• Chain 0 Signal Level – input signal level indicator of antenna number 0

(vertical polarization).

• Chain 1 Signal Level – input signal level indicator of antenna number 1

(horizontal polarization).

• Retries – percentage of transmit packet retries.

Graphical indicator:

The main item in the graphical indicator is Input Signal stripe. The height of the Input Signal stripe is measured by Input Signal Level scale in

dB. The higher is the stripe the stronger is the signal. The stripe can change it location along the Cross Fading scale that shows how

much influence the corresponding device antenna has on the other one, i.e. how much vertically and horizontally polarized signals influence each other. The higher value has the stripe according to the Cross Fading scale (the farther stripe is from the 0 dB value) the less influence antennas have on each other.

The top of the Input Signal stripe can be located in black (Good signal) or red (Bad signal) background areas or somewhere in washed border between them. It means the signal is good, bad or average correspondingly. When aligning the antenna it is recommended to try to achieve the stripe top to be located in the black area.

At the bottom of the Input Signal stripe may appear a special red sub-stripe. This sub-stripe indicates the presence of packet retries and its percentage of the total transmitted packets number.

During alignment test the Input Signal stripe may be moving along Cross Fading scale and increase or decrease in height indicating the changes in the received signal. When the top of the stripe is changing its location moving from one point on the background area to the other it commonly leaves pink and blue marks that indicate measured maximum and minimum levels of the signal at the particular point. Thus it makes possible to observe the “history” of the signal changes. To clear the marks use “Clear History” button at the bottom of the page.

Main recommendations when using “Antenna alignment tool”:

Page 77

InfiNet Wireless R5000 Technical User Manual

1. It is recommended to start antenna alignment with searching maximum signal level on a minimal possible bitrate. Afterwards automatic MINT mechanisms will set the most appropriate bitrate when “Autobitrate” mode will be enabled.

2. Input signal level should be between 12 and 50. ATPC is recommended to be enabled.

If signal level it is more than 50 it is recommended to lower amplifier power (ATPC will do it automatically).

If maximal signal level is less than 12 it is recommended to lower channel width (for example, from 20MHz to 10MHz).

In some cases signal level that is less than 12 may be enough for radio link operation. In this case one has to be guided by such parameters as number of retries and Error Vector Magnitude. If the number of retries is small and EVM is more than 21 (Input Signal stripe is green) then the radio link, most often, will be operating properly.

3. Retries value should be zero or as low as possible.

4. The top of an Input Signal stripe should be located in the black area.

5. The signal quality should be good: EVM value should be more than 21.

6. Input signals of the two antennas of the device should have similar Cross fading values (Input Signal stripes should be located symmetrically relating to the 0 dB value).

ALL described recommendations are applicable to both (Local and Remote) sections.

Link samples:

• Good link sample

• Bad link sample

Performance tests

The “Performance tests” page allows performing link throughput tests on all the bitrates that are available for the configured channel bandwidth.

“Performance tests” page view is shown below:

“Run Tests”/”Stop Tests” buttons at the bottom of the page start/stop the performance tests.

“Back” button returns to the “Device Status” page. Each row corresponding to a certain bitrate value can be selected or deselected

for participating in the performance test by using a check-box on the right of it. By using “Select all” check-box all the bitrates could be selected/deselected at once.

Page 79

InfiNet Wireless R5000 Technical User Manual

Three more parameters are available for management:

• “Bi-directional” check-box that allows choosing between making bi-

directional (when checked) and unidirectional (unchecked) performance tests.

• “Use mint” check-box allows performing MINT-enabled test when all the

traffic and link parameters are controlled and managed by MINT functions such as ATPC and autobitrate. In this mode the statistics for errors abd retries is not available.

• “Test time” parameter allows setting the duration of the test for each

bitrate in seconds (5 seconds by default).

The bitrates list on the “Performance test” page consists of the bitrates that corresponds to the channel bandwidth set on the unit (5/10/20/40MHz). To perform the tests for the bitrates related to the other channel bandwidth you need to reconfigure channel bandwidth (“Channel Width” parameter in the “Radio Setting” section of the “Basic Settings” page) on both units that form the tested link.

• Enable Grid – draws grid lines and highlights the special frequency

channel on the scan output. Special highlighted frequency channel can be used to mark a channel that the device is currently working on or that is planned for using

• Grid Width –bandwidth value for the highlighted frequency channel in

MHz

• Grid Frequency – central operating frequency for the highlighted

frequency channel

• Gradient Max RSSI – shows gradient-color marked “Max RSSI” values on

the Spectrum Analyzer output screen.

To start/stop «Spectrum Analyzer» use «Start Sensor Test»/«Stop Sensor Test» buttons.

“Last Snapshot” button outputs the final scanning results. It is used when doing a spectrum scan at the remote unit on the other side of the radio link. When running a spectrum scan at such a unit (accessible via the RF interface), connection to this unit will be lost for a scan time. "Last Snapshot" button allows viewing scan results after the connection is up again.

“Help” button – displays the help note for the Spectrum Analyzer.

You can get detailed information about scanned radio signals on a specific frequency. Just point a cursor on the needed frequency and you will see a hint with exact Signal level (dBm), Frequency (MHz), Noise Floor (dBm), RSSI (dBm), High RSSI (dBm), Max RSSI (dBm) values.

VII. Recommendations

1. Using InfiNet devices for High Bitrates

Using InfiNet devices on bitrates 48 and 54 Mbps (standard series), 104…130 Mbps (Xm-series, 20 MHz) and 240…300 Mbps (Xm-series, 40 MHz) has specific requirements because of low noise immunity of high-order modulation techniques (64 QAM).

One should take all possible precautions to prevent exceeding of parasite signals over receiver sensitivity threshold. The problem is aggravated by the presence of this parasite signal in entire spectrum.

Nevertheless, when using MINT architecture in most cases it is recommended to set the maximal bitrate on the radio interface and switch on autobitrate function. This will allow the system automatically and dynamically determine the most appropriate bitrate for the current environment conditions.

2. Design of Multi-sectored Base Stations

Using of multiple Base Station sectors with high output power with limited frequency and special gap between them increases noise level on the neighboring sectors. This can lead to the decrease of its performance. So we have ultimate choice: either optimizing base station for more bitrate/less range (without amplifiers) or optimize base station for more range/less bitrate (with amplifiers).

To deal with this problem most effectively it is recommended:

1. To increase number of sectors (commonly, up to 4-6)

2. Switch to the narrower bandwidth (5 or 10 MHz)

3. Use amplifiers and directional antennas at remote subscriber CPEs.

Remote subscribers can be configured for significantly lower than average bitrates providing more stable operating modes but those subscribers can decrease overall cell performance; so try to avoid mix solutions when the BS-CPE has a big difference for different subscribers.

4. Use Xm-series devices that have much higher performance, NLOS and

robust characteristics than standard-series ones.

3. Asymmetrical System Design

Following conclusions regarding using base station can be made:

• Downstream bitrate (base to CPE) is usually higher than upstream;

• Beam width of base station sectored antenna is 10 times wider than

beam width of subscriber antenna;

• Trying to deploy base stations on area heights leads to raising overall

noise level and reducing noise immunity;

• Subscriber SNR measured at a base station is significantly worse than

that of subscriber side.

• Increasing transmit bitrate does not influence the overall working

conditions and network performance;

• Increasing receive bitrate does worsen noise immunity and network

performance.

Every step in bitrate increasing requires 3 dB step improvements SNR. Asymmetry in 8 times corresponds to 9 dB. It means that without link quality losses we can have 2 times bitrate difference between upstream and

downstream. In order to maintain energetic parameters, we have to increase base station output power by 9 dB by means of built-in amplifier (for example to use 300-500mW devices).

4. «Bad subscriber» problem

While working in Point-to-Multipoint topology wireless network could face a problem when one of the subscriber devices has much poorer connection characteristics to Base Station than the other ones. Such subscriber device is using a considerable part of Base Station’s resources. While Base Station is trying to send him a packet on a low bitrate other subscribers are waiting for this transaction to finish. Therefore, all the networks’ performance will be reduced.

To lower the influence of such “bad subscriber” on the overall wireless network‘s performance it is recommended to decrease a priority of this subscriber (using “qm” command). In this case all the packets to “bad subscriber” will be sent after other subscriber stations already get their portions of data. This will result in wireless network performance optimization as subscriber devices’ operation won’t depend on the bitrate of “bad subscriber”.

5. TDM transmission

InfiNet Wireless equipment allows E1/T1 flows transmission via the radio channel in Point-to-Point topology. The System ensures transmission of 4 TDM channels and 45 Mbps Ethernet data simultaneously. Moreover, IW devices with TDM support allow Multi-hop TDM transmission when E1/T1 data are sent via several wireless Point-to-Point hops.
