Introduction
Section 1 Introduction
Your Trango Broadband M2400S radio system provides a reliable and robust means to deliver broadband access to
a wide geographic region through wireless Ethernet connectivity. This section will familiarize you with basic
operational concepts, as well as an overview of the various components and hardware of the M2400S system.
Overview
The M2400S is a highly versatile and cost effective outdoor point-to-multipoint solution for wireless broadband
service providers’ enterprise connectivity applications. The M2400S delivers 5 Mbps over the air, and operates in
the 2.4 GHz license free ISM band. Each radio includes an integrated dual polarized (horizontal and vertical)
antenna, as well as a connector for the attachment of an external antenna, such as a Yagi or an omni style antenna.
Note: If you are going to install an external antenna, refer to the M2400S Professional Installation Guide.
Contact Technical Support for access to the Professional Installation Guide.
The M2400S system consists of two types of radios: Access Points (APs) and Subscriber Units (SUs). Up to 126
subscriber units can be supported by a single AP, which acts as a hub in a star configuration. The AP delivers
wireless broadband service (Ethernet connectivity) to one or more SUs according to a proprietary adaptive dynamic
polling algorithm called SMARTPolling™. Network operators can co-locate multiple APs at a single cell site, thus
increasing the aggregate throughput available at each wireless point-of-presence (POP).
Figure 1: Typical Deployment
The AP typically resides at the center of the point-to-multipoint (PMP) network. It performs all management
functions, including the allocation of bandwidth for all associated SUs. The M2400S AP provides a host of
comprehensive tools and functions.
The M2400S system is classified as a Layer 2 multi-point bridge, thus all forms of Ethernet traffic will pass
seamlessly over the system. There is no limitation on the number of IP addresses or hardware devices to which an
individual subscriber unit may be connected.
Authentication of Subscriber Units is performed using a secure proprietary method, which is based on the MAC
address of the Subscriber Unit. In order to establish a wireless link the MAC address of the SU must be present in
the Access Point’s Subscriber Unit Database (SUDB).
Both APs and SUs are IP addressable and can be managed remotely across the network. Users can manage the
radios using the telnet command line interface or the graphical HTTP browser interface. The M2400S also
provides remote firmware upgrade capability utilizing TFTP. APs include a full featured SNMP agent for the
monitoring and controlling of both APs and SUs via SNMP.
The M2400S radios are powered using "power-over-Ethernet" for ease and low-cost installation. A single Cat-5
cable carries both Ethernet and DC power to the radio.
Trango Broadband Wireless — User Manual M2400S Rev. A

Page 6
Introduction
Both APs and SUs feature a handy "site survey" tool to check for interference, as well as RSSI tools for optimizing
antenna positioning. The M2400S also features variable receiver threshold, full power control, dual polarized
antennas, and various link diagnostic tools.
SmartPolling™ & Bandwidth Throttling
One of the major advantages of the M2400S system is the ability of the AP to handle multiple SU
connections and share the 5 Mbps data throughput efficiently. Bandwidth allocation is managed by the
AP’s SMARTPolling™ algorithm according to provisioning rules set up by the system administrator. The
AP polls each SU in a round robin format to determine if the SU has data to transfer. The SU only
transmits the data “upstream” to the AP when the AP gives authorization via a “transmit grant.” The SU
passes every “downstream” data packet from the AP and identifies packets intended for it. In order for an
SU to communicate with an AP, the system administrator must first add the MAC address and ID number
of the SU to the SUDB in the AP. The SMARTPolling™ algorithm will poll active SUs more often, thus
making the most efficient use of the 5 Mbps bandwidth. Several other parameters are considered in the
Smart Polling™ algorithm, including upstream/downstream committed information rate (CIR),
upstream/downstream maximum information rate (MIR), and Priority Setting.
Each of the above parameters is set in the AP by the system administrator and cannot be controlled at the
SU. These parameters will be covered in greater detail later in this text.
When power is first applied to a properly installed SU, it will scan all available channels listening for a
grant from an AP that has a matching Base ID and the SU’s MAC in the its SUDB. The SU will then stop
on that channel and respond to the AP using maximum RF power. Before the AP can add the SU to the
polling list, it must authenticate the SU by verifying the MAC address and performing a ranging operation
to the SU. Upon successfully locating and ranging the SU, the AP will then add the SU to the normal
polling list. Once the AP is regularly polling the SU, the SU is said to be “associated” to the AP.
Once associated, the AP will send a command to the SU to adjust the SU’s RF transmit power based on the Target
RSSI parameter set in the AP. This process is referred to as “power leveling.”
System operators may limit allowable bandwidth to specific customers utilizing the built-in CIR and MIR settings
(measured in kbps) for each SU.
Auto-retransmit Feature (ARQ)
The M2400S features ARQ or “Automatic Repeat Request,” which is the ability to correct for missing or corrupted
packets of data by requesting the sending radio to re-transmit the data. Both the AP and SU units implement a form
of ARQ known as “ARQ with Selected Repeat.” The use of ARQ is especially important in areas of high
interference. The ARQ feature can be turned on or off.

Hardware Overview
Section 2 Hardware Overview
This section provides detail about each radio in the M2400S family. Each radio in the M2400S family includes a
built-in, electronically switchable, dual-polarized antenna, as well as a reverse polarity SMA connector for the
attachment of an external antenna. For ease of installation all units are designed for outdoor installation and
powered by power-over-Ethernet (POE). The M2400S Access Point and Subscriber Units provide channels of
operation within the 2400 MHz ISM band, which spans from 2400 MHz to 2483 MHz. Default channel spacing is
10 MHz, allowing for 8 non-overlapping channels.
M2400S AP and SU Hardware Components
Each radio comes equipped with, a power-over-Ethernet (PoE) J-Box, an AC adapter, and mounting hardware.

Radio Management Concepts
Proper connections to the radios and careful IP/routing & planning will enable the network administrator to access
and manage the radios remotely over the network via TCP/IP. Radio management over TCP/IP can be performed
from computers connected to the Ethernet side of each radio. Computers connected to the AP can manage the SU
over their wireless connection. Likewise, computers connected to the SU can manage the AP, provided that switch
7 (TCP/IP access to AP from SU) is enabled on the AP. Switches will be covered later in this text.
Trango Broadband Wireless — User Manual M2400S Rev. A
Page 5
Page 10
Getting Started
Opmode
To fully understand radio management for the M2400S system, it is important to be familiar with the concept of
operation mode or “Opmode.”
APs and SUs can be in one of two Opmodes (“ON” or “OFF”). When in Opmode “OFF”, the AP is not
transmitting and is not attempting to associate with any SUs. Alternatively, when in Opmode “ON,” the radio is
transmitting and attempting to become associated.
Several functions, such as the site survey function and the SU RSSI function, can only be performed while the radio
is in a particular Opmode. See Appendix D (Command Set Reference) for a complete listing of commands, and the
appropriate Opmode for each command.
Switch Settings
M2400S firmware includes several “switches,” which are used to set certain operational parameters of the radios.
Switch settings can be changed via the HTTP browser interface or the Command Line Interface. For purposes of
radio TCP/IP management, the following four switches are important:
Switch 2 (SU) - TCP/IP access to SU from the AP’s side of network requires that the SU’s switch 2 (SW 2 –
TCP/IP for AP) be ON. Default setting for SW 2 (from factory) is ON.
Switch 5 (AP and SU) – In order to utilize the radio’s HTTP Browser interface, switch 5 (SW 5 – Enable HTTP)
must be ON. Default setting for SW 5 (from factory) is ON.
Switch 6 (SU) - TCP/IP access from Ethernet port of SU while in Opmode “ON,” requires that switch 6 (SW 6 –
TCP/IP Service for Ethernet Port) be ON. Default setting for SW 6 (from factory) is ON. If SW 6 is OFF,
TCP/IP access to SU from it’s Ethernet port is possible only if SU’s Opmode is “OFF.”
Switch 7 (AP) – TCP/IP access to AP from SU’s side of network requires that the AP’s switch 7 (SW 7 –
TCP/IP for SU) be ON. Default setting for SW 7 (from factory) is ON.
Passwords
In order to log into an M2400S radio (either through telnet or through the web browser interface), the user must
know the IP address and password. Both AP’s and SU’s feature two levels of passwords: Read Write (RW) and
Read Only (RO). Be sure to change both passwords (RW and RO) prior to deployment of your radios on a live
network. Passwords can be changed using the “password ro and password rw command in either the CLI interface
or in the command console of the browser interface.
Reset Button
Pressing the reset button will reset the radio’s IP address and password back to factory defaults.
Default IP (192.168.100.100) Default Password (trango)
Browser Interface
The M2400S (both AP and SU) features a convenient and easy-to-use web based configuration and management
tool. No additional software is needed on your computer other than a web browser. Most functions can be
performed using the browser interface, although several functions can only be performed using command line
interface (CLI). The browser interface also includes a “command console” page that allows the user to enter most
CLI commands without leaving the browser interface.
To use the browser interface, the following must be present:
• An Ethernet connection between a PC and the radio
• Ethernet PC connection with IP/subnet that is routable to the radio
• SW 5 ON (default)
• A web browser on the PC (i.e. Microsoft Internet Explorer)

Basic Configuration via Browser Interface
Section 4 Basic Configuration via Browser Interface
This section describes a few more basic concepts and how to establish a basic wireless link between AP and SU
using the Browser (HTTP) Interface. This section is written to address only the most basic steps in establishing a
link in the lab, or a bench-top environment. It is highly recommended to read the other sections of this manual to
gain an understanding of all important configuration parameters and procedures prior to deploying any wireless
equipment.
In this section you will:
• Learn about AP and SU Basic Configuration Screens and Parameters
• Populate AP’s Subscriber Unit Data Base (SUDB) with at least one SU
• Configure Other Basic AP Parameters
• Configure Basic SU Parameters
• Establish a Wireless Link
• Evaluate Link Quality
The M2400S uses the concept of “association” to indicate that the AP and SU’s are communicating. If all
parameters are properly set, the AP will begin actively searching for the SU’s in its SUDB. Once an active SU is
detected, the authentication and association process will begin.
Essentials in Establish inga Wireless Link with M2400S Series Radios
• Base ID in AP and SU must match
• MAC Address of SU must be entered into the AP’s SUDB
• SU must be set to “autoscan” all channels(switch 1), or be fixed on same channel as AP.
• AP must be in Opmode “ON”
• SU must be in Opmode “ON”
• Adequate signal strength must be received at each radio
If all of these parameters are met, the wireless link will automatically establish itself and Ethernet traffic will begin
to pass between the radios.
! Note: This section utilizes the Browser Interface as the configuration tool. For the equivalent procedure using
CLI commands, see Section 5.
Configuring the AP Subscriber Unit Database (SUDB)
Prior to establishing a wireless link, the user must configure the SUDB in the AP with each SU’s MAC address and
related settings. The SUDB includes information about each SU. Click on the Subscriber Database
modify, or delete SUs. The key information for each SU includes the following:
SU ID: User definable Subscriber Unit ID (1…126)
TYPE: PR (Priority) or REG (Regular). Priority SUs are polled more frequently than regular SUs.
Priority SUs will generally respond to the AP with less latency than regular SUs.
Group: SU to SU Group # (1..F in hex) for SU to SU communications within the same sector. Note:
This SU to SU feature allows interconnectivity between multiple SUs in the same sector,
without the need for a router. Only SUs with same SU to SU group # may communicate with
each another. If you do not want the SUs to communicate with each other, choose N/A for
SU to SU group. In order to use SU to SU communication, AP switch #3 must be ON.
Default setting for switch #3 is OFF.
! Note: SUs using SU to SU communication must be on the same subnet.
CIR UP: Committed Information Rate from SU to AP. Minimum upstream rate (measured in Kbps) at
which the SU will attempt to deliver bandwidth to the AP. Maximum setting is 5200.

CIR DOWN: Committed Information Rate from AP to SU. Minimum downstream rate (measured in Kbps)
at which the AP will attempt to deliver bandwidth to that SU. Maximum setting is 5200.
MIR UP: Maximum Information Rate from SU to AP. Maximum upstream rate (measured in Kbps) at
which the SU will attempt to deliver bandwidth to the AP. Maximum setting is 5200.
MIR DOWN: Maximum Information Rate from AP to SU. Maximum rate (measured in Kbps) at which the
AP will attempt to deliver bandwidth to that SU. Maximum setting is 5200.
DEVICE ID: MAC address of the SU.
Creating an SU in the SUDB
1. Connect to the AP (see Getting Started) and open the Subscriber Database page.
2. Enter the SU ID (range 1 – 126).
3. Select either PRIORITY or REGULAR.
4. If the SU will be part of an SU to SU group, enter the SU to SU group number.
5. CIR up (SU to AP Committed Information Rate) is the minimum upstream bandwidth for the SU in Kbps.
6. CIR dn (AP to SU Committed Information Rate) is the minimum downstream bandwidth for the SU in
Kbps.
7. MIR up (SU to AP Maximum Information Rate) is the maximum upstream bandwidth for the SU in Kbps.
8. MIR dn (AP to SU Maximum Information Rate) is the maximum downstream bandwidth for the SU in
Kbps.

9. Enter the Device ID (MAC Address of the SU).
10. Save and Activate changes.
Important! Always remember to Save and Activate changes, otherwise the SUDB will revert back to its
!
previous state after a power cycle or reboot.
Important! SUs using SU to SU communication must be on the same subnet.
!
Configure Other Basic AP Parameters
In addition to setting up the SU in the SUDB, the following settings from the AP’s Configuration page must be set
(or left at default).
Base ID: Base station ID, consisting of four user definable alphanumeric characters. Input of Base ID will
be in the format of xxxx. Where x is any character from the set : { 0..9; a..z; A..Z;
'!@#$%^&*()_+[]\<>,./?' } . The Base ID is typically assigned to a single AP or a group of APs at
a particular cell site. The Base ID in the AP must match the Base ID in the SU in order for a link to
be established. This parameter can only be changed while in Opmode "OFF."
AP ID: User definable AP ID (00-FF). Default is last two digits of MAC ID. Once authenticated, the AP
will automatically assign its AP ID to the SU. This parameter can only be changed while in
Opmode “OFF.”
IP Address, Subnet Mask, and Gateway:
The IP address used on the radio is for management purposes only. Since this is a layer-II device,
these parameters do not play a role in establishing the wireless link.
Default Opmode:
Will initiate Operation Mode of the radio after a power cycle or reboot. When the radio enters
Opmode "ON," it will be transmitting. When the radio enters Opmode "OFF," it will not be
transmitting. The radio can be put into Opmode "OFF" regardless of its default Opmode by
telnetting into the radio within the first 30 seconds after a power cycle or reboot.
Active Channel/Polarization:
Is the current channel and antenna polarization of the unit when in Opmode "ON."
To configure the AP’s other basic settings, complete the following steps:
1. Connect to the AP (see Getting Started) and open the Configuration
page.

Page 18
Basic Configuration via Browser Interface
2. Set Base ID, or choose default base ID of 0000 (must match the SU).
3. Set AP ID (00-FF HEX).
4. Set IP, Subnet, and Gateway, or leave at default settings. Keep in mind if you change the IP Settings of
the radio you will loose your HTTP session when you save and activate.
5. Choose Active Channel (1-8).
6. Choose Antenna Polarization (H or V) or choose E for an external antenna.
7. Ensure default Opmode is "ON."
8. Save and Activate Settings.
9. If this is the first SU to be added to the SUDB, reboot the AP.
After reboot, the AP will automatically enter its default Opmode, after approximately 40 seconds. At this time it
will begin actively searching for all SUs in its SUDB. Once an active SU is detected, the authentication and
association process will begin.

Configure Basic SU Parameters
In order to establish a working link, the Base ID in the SU must match the Base ID of the AP.
SU Basic Setup:
1. Connect to the SU (see Getting Started) and open the Configuration page.
2. Set Base ID (must match the AP).
3. Set IP, subnet, and gateway, or leave at default settings. Keep in mind if you change the IP Settings of the
radio you will loose your HTTP session when you save and activate.
4. Ensure default Opmode is "ON."
5. Save and Activate Settings.
6. If Opmode is “OFF,” click Opmode ON
At this point, if all parameters have been set correctly and the radios are within range, a wireless link between the AP and
SU will automatically become established. Once this occurs the SU will be in “associated” status.
Allow approximately 60 seconds for the radios to complete the boot-up cycle and to associate. If the AP is busy
servicing many SUs, the association process may take slightly longer.

LED Summary
At this point it is useful to learn about the various LEDs that can be found on the bottom of the radio. These LEDs
can assist the user in determining radio and link status.
RSSI LEDs (YELLOW) - In all modes except "Survey,"
the unit's four yellow LEDs indicate the level of RF
signal being received from a valid AP.
Yellow LED 1 (rightmost): On when RSSI > -85 dBm
Yellow LED 2 : On when RSSI > -75 dBm
Yellow LED 3 : On when RSSI > -65 dBm
Yellow LED 4 (leftmmost): On when RSSI > -55 dBm.
In addition, these 4 LEDs will flash once to indicate the
'factory reset' button has been activated.
10/100 Link LED (GREEN) Illuminated when link speed is
negotiated at 100 BaseT. It is off
when link speed is 10 BaseT or not
connected.

On this page the user can immediately see which SUs are currently associated. In the page shown, SU ID# 1 is
associated, and SU ID# 17 is not. Consider "Power Off" status synonymous with "not associated."
RF Link
Loopback Test
The RF Link Loopback
Test is one of the built-in
tools for evaluating the
quality of the wireless link.
Specify an SU ID and time
in minutes to conduct the
test. The test is prioritized,
so it will take precedence
over all other traffic. 1600
byte packets are sent and
received between the SU
and AP at 50 millisecond
intervals over the time
specified.

SU Ranging Test
This test reports the SUs distance
from AP in miles, received signal
strength for uplink and downlink,
and SU TX Power. Use a link budget calculator to analyze results. Significant differences between calculated and
actual values could indicate alignment or LOS issues!
Advanced Setup Page
The advanced set up page includes several important parameters including RF TX Power, RF RX Threshold,
target RSSI from SU (AP only), and Channel Table.
RF TX Power: Sets the conducted RF power output of the radio. Highest allowable setting is +23 dBm.
Lowest setting is +10 dBm. This value does not include antenna gain.
RF RX Threshold: Sets the receive threshold of the radio. The radio will not process signals received below
this level, so it is very useful for interference mitigation. For a smaller radius of
operation, use a higher threshold (-75 is higher than -80).
Target RSSI from SU: Used by the powerleveling process to automatically adjust the RF output power level of
all SUs in a sector so the signal strength from each SU, as measured at the AP, will be
roughly equal.
Trango Broadband Wireless — User Manual M2400S Rev A
Page

Channel Table: Assigns channel numbers to actual frequencies of operation. Default settings allow the
largest number of channels (8) within the band, while still maintaining a 10 MHz channel
spacing.
Other Key Parameters
This section describes the remainder of the parameters listed on the System Information page. Most of these
parameters are the same for both APs and SUs.
Hardware Version: Hardware version is factory-set and can not be changed by the user.
FPGA Version: Low level field programmable gate array firmware currently loaded on the radio. Normally the
FPGA firmware will not require upgrading.
Firmware Version: Main firmware. In this example, the version part of the string is 1p0 (v1.0), the hardware
code is H8006, and the remainder of the string is a date code.
Device ID: MAC address of the radio.
S/N: Serial number of the radio.
Telnetd Port: User changeable telnet port of radio.
TFTPd: Current status of TFTP daemon. Used for uploading firmware.
MIR Threshold: Shown in Mbps (0..5) Maximum Information Rate (MIR) Threshold. The MIR Threshold is the
aggregate throughput of the AP at which the AP will start to enforce CIR rules for the SUs.
Trango Broadband Wireless — User Manual M2400S Rev A
Page

Page 24
Basic Configuration via Browser Interface
Active Channel: The channel currently being used by the radio.
RFRX Threshold: Sets the receive threshold of the radio. The radio will not process signals received below this
level, so it is very useful for interference mitigation. For a smaller radius of operation use a higher threshold (-65 is
higher than -70).
Broadcast Packet: This software switch (0) enables/disables the blocking of Ethernet control packets, except
ICMP and ARP, to reduce the amount of unnecessary overhead introduced into the wireless link.
SU to SU Communication: If enabled (switch 3), SUs with matching SU to SU groups (except group 0) can
communicate in peer-to-peer mode through the AP without the need of a router behind the AP. SUs using SU to
SU communication must be on the same subnet.
TCP/IP Service for SU: If enabled, the AP can be accessed via TCP/IP (Telnet or HTTP) from the SU side of the
network via the wireless link.
Remarks: User definable radio information (i.e. customer name, address of installation, etc). A maximum of 28
characters can be stored.
Site Survey Page
The Site Survey page provides a useful tool for detecting and measuring interference. The radio must be in
Opmode “OFF” in order to use this feature.
Enter the number of minutes desired for the survey, and select the polarization H, V, or E (for an external antenna).
Click "Start Survey." A survey of the default 8 channels will be performed. Results are reported in dBm per
channel as average and peak. A channel is reported to be "Clear" if the peak and average are below the RF RX
Threshold by more than 8 dB.

Subscriber Unit Database Settings
Once you are familiar with the basic system information presented above, you are ready to add one or more SUs to
the SUDB. There are five basic commands related to the SUDB: sudb add, sudb cirmir, sudb defaultcirmir, sudb
view, and save sudb.
Adding an SU
You will need to know the following information to add an SU to the database:
1. MAC ID of the SU (printed on the back of the SU).
2. Polling priority: either PRIORITY or REGULAR.
! Note: SUs designated as PRIORITY will get polled more often by the AP.
To add an SU to the SUDB, use the following command and syntax:
sudb add <suid> <pr|reg> <device id>
suid: SU ID
pr: priority user
reg: regular user
<device id>: xx xx xx xx xx xx in hexadecimal (this is the MAC address of the SU)
Example:
#>sudb add 5 pr F3 3C 50 67 89 D4
In this example, SU ID 5 was added as a Priority SU. The MAC ID of that SU is F3 3C 50 67 89 D4.
! Note: You can add up to 126 entries in the SUDB
CIR / MIR Commands
The default CIR/MIR setting is 5000 Kbps for upstream and downstream values.
To change SU’s CIR/MIR settings, use the following command:
sudb cirmir <suid | all> <cir dn> <cir up> <mir dn> <mir up>
Example:
#>sudb cirmir 5 128 256 5000 5000

Basic Configuration via CLI
In this example, SU #5’s CIR downstream is set to 128 and CIR upstream is set to 256. MIR upstream and
downstream are set to 5000.
To change the default CIR/MIR values, use the following command:
sudb defaultcirmir <default cir dn> <default cir up> <default mir dn> <default mir up>
Example:
#>sudb defaultcirmir 256 256 512 512
To view the entries in the SUDB, type the command sudb view.
To save the changes you have made to the SUDB, type save sudb
Other important SUDB related commands are sudb delete, sudb gid, and sudb modify. See Appendix A for
descriptions of these commands.
Important! After updating the SUDB, type the command save sudb to save the SUDB. If you do not save the
!
SUDB file will revert back to its previous state after power cycle or reboot.
Important! SUs using SU to SU communication must be on the same subnet.

Cabling and Grounding Considerations
Grounding Example
Proper mounting of the radio includes
consideration for grounding. Please note that if
the radio is attached to a metal pole that is
earth-grounded, no other grounding is
necessary. If the radio is not earth-grounded
via the mounting bracket, you must attach a
grounding wire to the grounding stud on the
back of the radio as in the adjacent diagram.
Installation Notes
Access to the radio’s RJ-45 Port and LED status lights are purposely located at the bottom of the radio to minimize the risk of
water intrusion. Do not mount the radio upside down.
The J-Box is not a weatherized device and must be located either indoors or in a weather-protected cabinet.
Shielded twisted pair Cat-5 cable is recommended for all installations unless cable is placed in metal conduit.
The shield within the Cat-5 cable does not need to be grounded if the radio itself is grounded.
It is important to consider that most Cat-5 cable will deteriorate over time if exposed to the weather (especially direct
sunlight). Conduit (metal or PVC) is recommended to protect the cable.
!
It is important to provide strain relief and drip loop for STP Cat-5 cables. Do not mount the radio upside down.
Figure 10: Grounding of Radio
Important! The Ethernet port compression washer should be loosely tightened around the Cat-5 cable
to allow pressure equalization within the radio enclosure. Leave approximately 1 mm around the Cat-5.

Once you are familiar with the basic operation of the radios, you are ready for deployment in the field. The deployment
process consists of the following steps:
• Site Selection
• Site Survey
• Channel Planning
• SU Antenna Alignment
• Link Management Commands
Site Selection
Proper site selection for your AP will help ensure a successful deployment. Site selection will depend on a wide variety
of factors, but from the radio’s performance standpoint consider the following:
• Path from AP to SU should provide as few obstructions as possible. It is advisable to place the AP as high as
possible on a tall building or tower.
• Ethernet cable is limited to 300 feet from Ethernet device (router, switch) to radio.
• Radios require grounding for optimal performance.
• AP provides sector coverage of 60 degrees azimuth and 18 degrees elevation
• Consider nearby sources of interference that could degrade performance of radio. Mount radios as far from
sources of interference as possible.
• Perform a site survey to determine noise levels and the relative clarity of channels at the chosen installation
location.
Site Survey
Both the AP and SU provide a powerful on-board site survey tool. This tool will tell you if there is interference present in
the 2.4 GHz ISM band.
Command: survey <time> <antenna>
In order to use the survey command, the radio must be in Opmode “OFF.” The survey can be performed for up to 10
seconds per channel (incrementing by 5 MHz). The test can be run for either the (h) horizontal polarization, (v) vertical
polarization, or (e) external antenna.
Prior to performing the site survey, place the radio in the installation spot, and aim the radio in the desired direction.
The results of the test will provide you with a listing of each channel in the band, the average signal received, and the
maximum signal received during the survey period.
In general you will be looking for frequencies with interference signal strength of –85 dBm or lower. If interference is
present on various channels, it is recommended that you chose clean channels or alternate polarizations for your
deployment. If it is not possible to use a clean channel/polarization combination, there are various methods available to
mitigate the affects of interference. These methods include the use of the RFRX THRESHOLD settings, the use of
external shields, and/or external narrower beam antennas.

Once the site survey is completed you are ready to install your radios. It is recommended that APs be installed first. The
reason for this is that the SU has a built-in RSSI tool that will help you properly aim the SU toward the AP to achieve the
maximum signal strength.
In this example of a survey
on the vertical polarization
for 2 seconds for each 5
MHz portion of spectrum,
the largest amount of
energy is detected at
frequency 2415 MHz.
The asterisks (****) indicate
the highest avg amount of
energy detected and
corresponds to the number
of yellow colored LEDs lit.
Note: The survey also
covers spectrum outside of
the operational range of the
radio.
AP Search and SU Antenna Alignment
Once the AP is installed and aligned in the correct general direction, it is time to install the SU. The hardware installation
of the SU is identical to the AP, including considerations for line-of-sight, cable distances, cable type, weather sealing,
and grounding.
Trango Broadband Wireless — User Manual M2400S Rev A

Deployment
Once the SU is installed and aimed in the general direction of the AP it is time to perform an RSSI (relative signal
strength indicator) test to determine the signal strength from the AP. Now you can precisely align the SU antenna for
maximum signal strength.
Although it is possible to rely upon the Subscriber Unit’s LEDs for alignment, more precise RSSI readings are available
from the command rssi.
In conjunction with the rssi command, it is also useful to perform the apsearch command. This command will tell you
which AP is providing an adequate signal at the location of the SU.
AP Search
1. Ensure AP is in Opmode “ON.”
2. Run the apsearch command to verify which AP is providing the strongest signal strength.
#> apsearch

RSSI Command for Antenna Alignment
In this example, an AP is detected on channel 1 with
polarization horizontal. Furthermore, the Base ID is 1234
and the MAC address is 00 01 DE 18 6A 05.
Step 1 Telnet into the SU (while in Opmode “OFF”). Use the freq and antenna command to note current radio settings.
Step 2 Run the rssi command. The telnet session screen will begin a continuous readout of the received signal strength.
As you read the RSSI reading, move the antenna in the horizontal and vertical planes until the maximum RSSI reading is
achieved. To allow for plenty of fade margin we recommend a continuous RSSI reading of -78 dBm or better. An RSSI
of –88 dBm will allow you to establish a wireless link, but there may not be sufficient fade margin for reliable and
continuous operation.
Example 1 has the wrong freq and antenna settings:
#> rssi
[ 1] peak -99 dBm avg -99 dBm
[ 2] peak -99 dBm avg -99 dBm
[ 3] peak -99 dBm avg -99 dBm
Example 2 has the correct freq and antenna settings:
#> rssi
[ 1] peak -38 dBm avg -80 dBm *
[ 2] peak -38 dBm avg -75 dBm **
[ 3] peak -37 dBm avg -75 dBm **
Step 3 If it is not possible to receive an adequate RSSI reading it may be necessary to reorient the AP (up/down,
left/right) to increase the output power. Or move the SU to a location with better line-of-sight to the AP. Alternatively
consider using external antennas on either the AP or SU or both.
Once you are satisfied with the RSSI reading, tighten down the SU in the optimum position. To stop the RSSI continuous
readout hit SPACE ENTER.

SU Alignment Using LEDs
The LED RSSI indicators on the bottom of the radio provide a handy alignment tool. If all four LEDs are lit, the unit is
receiving –64 dBm or stronger. If no LEDs are lit, there is not sufficient signal strength to establish a wireless link.
Lit LEDs Signal Strength
0 LED -86 dBm or weaker
1 LED -76 to -85 dBm
2 LED -69 to -75 dBm
3 LED -66 to -70 dBm
4 LED -65 dBm and stronger
Note: RSSI tool (telnet or LEDs) will show all RF energy on
a given freq. i.e. – a nearby SU on the same freq. passing
traffic may give the appearance of a strong signal from your
AP when in fact it is not and cause a misalignment.
Link Management Commands
Once the radios are properly aligned for maximum RSSI, ensure the SU’s default Opmode is “ON” and that all
configuration parameters are correct.
Reboot the SU. Once the SU enters Opmode “ON” the authentication process will begin, and the two radios will begin to
associate. From the AP side, there are several basic diagnostics commands, such as su ping, su info, and su testrflink,
which can check if a reliable RF link has been established. It may take one minute or more for the association process to
complete. This process may take longer if there are many SUs in the sector.
If all tests show favorable results, the wireless link will automatically begin passing Ethernet traffic between the
radios.
In establishing and diagnosing the quality of the link between AP and SU(s), there are a few commands that are especially
useful. All of these commands are performed at the AP. A summary of these commands follows:
su
Displays the status of all SUs in the AP’s SUDB. SUs in the SUDB will appear by SU ID, and will be classified into one
of the following status categories: Associated, Associating, or OFF. All associated SUs will be indicated.
Example:
#> su
[Priority] 1
[0] 1
[1]
[2]
[3]
[4]
[5]
[Associating]
[Power Off] 17
Success.
su ping <suid>
AP will send 10 RF pings to the designated SU ID. The response from each ping will indicate latency (in micro-seconds)
and the received signal strength (RSSI) from the SU for each of the 10 pings. Note this command will also tell you the
distance from the AP to the SU.
Example:
#> su ping 1

su linktest <suid>
This command checks the integrity of the wireless link from the standpoint of performance (throughput) and over-the-air
packet loss. The AP will send 100 1600 byte packets to the SU, and the SU will return the packets it receives to the AP.
A perfect link (without dropped packets) will yield average throughput of 5,000 Kbps. If heavy packet loss occurs it may
be caused by interference or multi-path.

su testrflink <suid>
This command also checks the integrity of the wireless link from the standpoint of over-the-air packet loss. In this test,
the AP will send 20 large (1512 byte) packets to the SU, and the SU will in turn send the same 20 packets back to the AP.
The expected result of an error free link is 20..20..20, indicating (in the following sequence) 20 packets sent from AP, 20
packets received back at AP, and 20 packets received at the SU. Any results other than 20..20..20 indicates a performance
problem, most likely due to interference or inadequate signal to noise ratio. For thorough results it is recommended you
run the command repeatedly for at least 1 minute or more to determine if packets are passing without error consistently
over time. This command will give results without the help from ARQ. Note: This test does not provide as much detail
as the linktest command.
The “r” is used in this command to repeat the RF link test repeatedly until the user terminates the test by hitting SPACE
ENTER.
Example:
#> su testrflink 1 r
Press [space] then [enter] to stop

[ 5] ...........[AP Tx] 20 [AP Rx] 20 [SU Rx] 20
Success.

As another example, a result of 20..10..18 would indicate 20 packets sent from the AP, 18 packets received at the SU, and
10 packets received back to the AP. These types of results may be caused by Fresnel zone infringements, interference, or
multi-path.

ARQ with Selected Repeat and Multirate Feature
The M2400S features ARQ, or “Automatic Repeat Request,” which provides the ability to correct for missing or erred
packets of data by asking the sender to re-transmit the data.
Both the AP and SU units implement a form of ARQ known as Selective Repeat.
The units make a first attempt at transmitting a data frame using the 5.5 Mbps rate. Then, if a re-try is required, the 2nd
attempt will be at 5.5 Mbps as well. The 3rd and 4th attempts will be at a rate of 2.75 Mbps. After the 4th attempt there
will be no more re-tries. A counter describing “maximum retries reached” will be incremented.
• A minimum of 100ms is placed between re-transmission requests.
• The units buffer up to 1200 frames or 4 seconds worth of RF TX Data frames to support the ARQ algorithm.
• The AP unit maintains counters concerning the ARQ algorithm on a per SU basis. The counters shall include the
following data:
Total Transmitted Frames
Total Retransmission Attempts
Total “Maximum Attempts Reached”
The SU also maintains a counter concerning its use of the ARQ algorithm. Counters include the following data:
Total Transmitted Frames
Total Retransmission Attempts
Total “Maximum Attempts Reached”
Section 8 Management
Section Topics:
• Radio Management Access via TCP/IP
• SU Management from AP’s command set
• SNMP
Radio Management Access Via TCP/IP
The IP Address of an M2400S radio is for management purposes only. The IP address is not used for routing purposes or
passing traffic. Users should take care to set appropriate IP schemes for all management activities including upgrading
the radio’s firmware. It is not uncommon for users to assign public IP addresses to radios so that they can be accessed
from anywhere on the Internet. In order to gain TCP/IP access to the SU (from either side of the wireless network) ensure
that the SU switches 2 and 6 are turned on. In order to gain TCP/IP access to the AP from the SU side of the wireless
network ensure that AP switch 7 is turned on.
SU Management from AP
The AP provides several commands that permit the management of associated SUs. In fact, most system management
functions are performed by issuing commands from the AP. Presented below are a few examples of these commands:
su <all | suid, 1..126>
su info <suid, 1..126>
su linktest <suid, 1..126>
su password <suid | all> <rw|ro> <new password> <new password>
su ping <suid, 1..126>
su reboot <suid | all>
su sw <suid | all> <sw#, 0..7> <on | off>
su testrflink <suid, 1..126> <r>
su testrflink <all> <r>
Note: SU commands issued from the AP will automatically update the SU’s flash memory. No save ss command is
necessary.

Management
You can remotely change the SUs password for a single SU or all SUs in a sector using the syntax below:
su password <suid | all> <rw | ro> <new password> <new password>
Example: su password all rw hello hello
To remotely change the read write password on all SUs to “hello.”
You can change the SUs IP, subnet, and gateway using the syntax below:
su ipconfig <suid> <new ip> <new subnet> <new gateway>
Example: su ipconfig 7 192.168.10.10 255.255.255.0 192.168.10.1
In this example SU ID 7’s IP address was changed to 192.168.10.10, the subnet mask to 255.255.255.0, and the gateway
to 192.168.10.1.
A complete description of these commands and many others can be found in Appendix A − Command Set Summary.
Loading Multiple SU’s into SUDB using DLOAD Command
To load a full database of SU entries into the AP’s SUDB, you will need to create an SUDB in ASCII text file format. As

SNMP
The M2400S supports Simple Network Management Protocol (SNMP) for network management. Network management
consists of the following 4 categories: configuration, accounting, alarm, and monitoring and control. These capabilities
allow the network operator to provide superior services through higher network availability and an integrated accounting
system. For more information on SNMP and its uses you can visit http://www.faqs.org/faqs/snmp-faq/.
The Trango SNMP solution supports MIB-II (system only) and the Trango proprietary Management Information Base
(MIB). The SNMP agent resides on the AP ONLY. It gathers health, status and performance statistics from all SUs
locally. The agent then responds back to the SNMP manager upon request.
Users interested in using the SNMP functionality should review the entire M2400S MIB for a complete understanding of
its features. The M2400S MIB is available for download at:
http://www.trangobroadband.com/support/downloads.htm
The following is an overview of a few of the more commonly used SNMP objects in the M2400S system.
Objects for Monitoring and Control
SU Bandwidth Monitoring
• suRFInOctets – Number of octets of payload transmitted from AP’s RF port.
• suRFOutOctets – Number of octets of payload received on AP’s RF port.
AP Bandwidth Monitoring
• aptrafficEthInOctets – Number of octets of payload received on the Ethernet port.
• aptrafficEthOutOctets – Number of octets of payload transmitted from the Ethernet port.
• aptrafficRFInOctets – Number of octets of payload received on the RF port.
• aptrafficRFOutOctets – Number of octets of payload transmitted from the RF port.
Link Status Monitoring –Various traps are defined as follows:
• SU Link Up – When SU associates to the AP
• SU Link Down – When SU disassociates from the AP
AP and SU Control – SNMP also provides several control capabilities. The majority of the features available on the CLI
are also available in SNMP. Here are a few of these features:
• Add/delete subscriber
• Change channel
• Set power
• Set radio sensitivity
Review the Trango M2400S MIB for the complete listing of MIB Objects.
SNMP Setup
Trango Broadband provides only the MIB portion of the SNMP Management system. The radios act as individual agents,
and it is up the user to provide an SNMP Manager software from a third party vendor. Below is an example of the setup
process for SNMPc from Castle Rock™.
1. Unzip trangopkg.zip file to a local temporary directory.
2. Go to your local temporary directory. You will find 4 files as shown below.

By default, the Read Community is set to “public,” and the Write Community is set to “private” in the AP. The Trap
Community is “SNMP_trap.” The manager needs to have the same settings in order to communicate with the AP
successfully.
To send traps from the AP set the following:
• trap destination IP (Trango MIB object trapconfig–trapconfigInfo)
• trap community string (Trango MIB object trapconfig–aptrpTable-AptrpEntry)
• enable each trap (Trango MIB object traponfig–aptrpTable-AptrpEntry)
