Introduction
Section 1 Introduction
Your Trango Broadband M2400S radio system provides a reliable and robust means to deliver
broadband access and wireless Ethernet connectivity to a wide geographic region. This section will
familiarize you with basic operational concepts as well as an overview of the hardware and the various
components 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 (AP) and Subscriber Units (SU). 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).
Typical Deployment
The AP typically resides at the center of the point-to-multipoint (PMP) network and 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 and
unlimited IP addresses 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 units. In order to establish a wireless link the MAC address of the SU
must be present in the Access Point’s SU database.
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 monitoring and control of both APs and SUs via SNMP.
Trango Broadband Wireless — User Manual M2400S Rev. A

Page 5
Introduction
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.
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 feature 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 SMART Polling™ 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 user database in
the AP. The SMART Polling™ 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 with matching Base ID and the SU’s MAC in the AP’s SU Database. 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 SU is regularly being polled by
the AP, 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 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 Request for Re-transmission”, which is the ability to correct for
missing or errored 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 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 the radio itself, a power-over-Ethernet (PoE) J-Box, an AC adapter, and
mounting hardware.
Basic Components of an M2400S Radio
Bottom of Radio
At the bottom of the M2400S are two access ports: a twist-on weatherproof cable port for RJ-45 Ethernet
(and PoE), and a translucent access cover plug over the unit’s diagnostic LEDs and reset button. The
LEDs will be discussed later in this text.

Section 3 Getting Started
This section explains how to power your radios, establish TCP/IP connectivity to the radios, as well as
how to access the HTTP browser and the command line interfaces.
Connections and Power
Connection and powering of radios is the same for APs and SUs.
• Connect a Cat-5 (straight through) Ethernet cable (we recommend shielded twisted pair)
between the Radio port of the J-box and the RJ-45 connector on the radio. Note: this cable will
carry Power over Ethernet (PoE).
Trango Broadband Wireless — User Manual M2400S Rev. A
Page 4
Page 8
Getting Started
• NETWORK port connection is as follows:
If connecting to a COMPUTER, use a Cross-Over Ethernet cable from the NETWORK port of
the J-box to the computer’s Ethernet port.
If connecting to a HUB, SWITCH, or ROUTER, use a Straight-Thru cable.
• Plug the AC adapter into an AC outlet.
• Use Ground Lug to ground PoE device and shielded CAT5
• Use voltmeter contacts to check line voltage (can be done with or without load)
Wiring Diagram
Both green LEDs on the J-box should be lit, indicating power is present at the J-box as well as the radio.
You are now ready to configure the radio via the Ethernet port.
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; and, computers connected to
the SU can manage the AP, provided that switch 7 (TCP/IP access to AP from SU) is enabled at the AP.
Switches will be covered later in this text.
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; “OFF” opmode, or “ON” opmode. When in “OFF” opmode,
the AP is not transmitting and it is not attempting to associate with SUs. Alternatively, when opmode is
“ON”, the radio is transmitting and attempting to become associated.
Trango Broadband Wireless — User Manual M2400S Rev. A
Page 5
Page 9
Getting Started
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 opmode is 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 logon to 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 which 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)
In order to use the browser interface – simply connect the radio to a PC, and type the radio’s IP address
(default IP address=192.168.100.100) into the web browser (i.e. Microsoft Internet Explorer). This will
bring up a login page.
NOTE: Login pages for AP and SU are similar.

Command Line Interface
Although most radio functions can be managed via the browser interface, the command line interface
(CLI) provides slightly more functionality and is usually the management tool of choice for experienced
users. The CLI can be accessed through Telnet.
Telnet
Open a command prompt (DOS) session on your PC. Open a Telnet session by typing:
telnet [ip address of radio]
All Trango radios are pre-configured at the factory with a default IP address of 192.168.100.100. The
factory default password is trango. Once you connect to the radio you will be greeted with current
hardware and firmware information and prompted for a password. Type in the read-write (RW) password
and press enter.

Troubleshooting
If you cannot telnet into the radio or open a browser session, check cable connections, ensure proper
use of cross-over vs. straight-through cable and ensure PC’s subnet is routable to radio’s IP address. If
you still cannot access the radio’s management interfaces, consult the troubleshooting guide which is
available at www.trangobroadband.com in the Technical Support area of the website.

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 SU database (SUDB).
Once an active SU is detected, the authentication and association process will begin.
Essentials to Establish a Wireless Link with M2400S Series Radios
• Base ID in AP and SU must match
• MAC Address of SU must be entered into the AP(SUDB)
• SU must be set to either “autoscan” all channels, or it’s channel must 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
Prior to establishing a wireless link, the user must configure the subscriber unit database (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 page to add, 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 much more frequently than
regular SUs. Priority SUs in general will 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.
Trango Broadband Wireless — User Manual M2400S Rev A
Page 11
Page 15
Basic Configuration via Browser Interface
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. The MAC address and the AP’s BASE ID are the basis for
authentication with the AP.
Creating an SU in the SU Database.
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.
Trango Broadband Wireless — User Manual M2400S Rev A
Page 12
Page 16
Basic Configuration via Browser Interface
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 or 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 SU Database, the following settings from the AP’s Configuration
page must be set (or left at default).
Base ID: Four characters, alphanumeric, user definable base station ID. Input of BASEID shall 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 opmode is
"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 opmode is “OFF”.
IP Address, Subnet Mask, Gateway:
The IP address used on the radio is for management purposes only. Since this is a layerII 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 "ON" mode, it will be transmitting. When the radio enters "OFF" mode, 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 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.
Trango Broadband Wireless — User Manual M2400S Rev A
Page 13
Page 17
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 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, (ON) 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 activate opmode
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.

The RF Link Loopback
Test is one of the built-in
tools for evaluating the
quality of the wireless
link. Specify an SU ID

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
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.

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
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 on the AP at which the AP will start to enforce CIR rules for the SUs.
Trango Broadband Wireless — User Manual M2400S Rev A
Page 19

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 packet
except ICMP and ARP to reduce the amount of unnecessary overhead introduced to the wireless link.
SU to SU Communication: If enabled (switch 3=on), 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 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.

Page 23
Page 27
Basic Configuration via CLI
1. MAC ID of 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 database, 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 an SU ID 5 was added as a Priority SU. The MAC ID of this SU is F3 3C 50 67
89 D4.
Note: You can add up to 126 entries in the SU database
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
In this example, SU #5’s CIR downstream is set to 128, CIR upstream is changed to 256. MIR upstream
and downstream is 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 SU database, type the command sudb view.
To save the changes you have made to the SU database, type save sudb
Other important SU database related commands are sudb delete, sudb gid, and sudb modify. See
Appendix A for descriptions of these commands.

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.
Important! The Ethernet port compression washer should be loosely tightened around the

Deployment
Section 6 Deployment
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 which 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 this 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 amber colored LEDs lit.
Note: the survey also
covers spectrum outside of
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,
polarization horizontal. Further, 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 -80 dBm
1 LED -75 to -79 dBm
2 LED -70 to -74 dBm
3 LED -65 to -69 dBm
4 LED -64 dBm and stronger
Collocation and Channel Planning (temporary example from 900 manual)
With proper channel planning and adherence to installation guidelines, multiple M900S access points may coexist and operate interference-free on the same tower or building. The main consideration when collocating
access points is to ensure at least 10 ft. of vertical separation. Please see the diagram below for collocation
spacing and suggested channel plan.
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 to ensure that 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 APs database. SUs in the SU database will appear by SU ID, 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 <su#>
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
[#Begin]
[001]
Ping #0 -> -52 dB 220 us 0.0 mi
Ping #1 -> -53 dB 219 us 0.0 mi
Ping #2 -> -53 dB 220 us 0.0 mi
Ping #3 -> -52 dB 220 us 0.0 mi
Ping #4 -> -53 dB 219 us 0.0 mi
Ping #5 -> -52 dB 220 us 0.0 mi
Ping #6 -> -50 dB 220 us 0.0 mi
Ping #7 -> -52 dB 220 us 0.0 mi
Ping #8 -> -52 dB 220 us 0.0 mi

su linktest <su#>
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 <su#>
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, 20 packets received at the SU. Any
results other than 20..20..20 indicate 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 linktest
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

[ 4] ...........[AP Tx] 20 [AP Rx] 20 [SU Rx] 20
[ 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, 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 M900S features ARQ or “Automatic Request for Re-transmission” 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, that 2nd attempt shall be at 5.5 Mbps rate as well. e 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.
Trango Broadband Wireless — User Manual M2400S Rev A
Page 36
Page 40
Management
• 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 7 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 which 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.
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 th syntax below:
su ipconfig <suid> <new ip> <new subnet> <new gateway>
Trango Broadband Wireless — User Manual M2400S Rev A
Page 37
Page 41
Management
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 is changed to 192.168.10.10, the subnet mask is changed to
255.255.255.0, and the gateway is changed 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

SNMP
The M2400S supports Simple Network Management Protocol (SNMP) for network management. Network
management consists of the following 5 categories: configuration, accounting, alarm, monitoring, and control.
These capabilities allow the network operator to provide superior services through higher network availability
Trango Broadband Wireless — User Manual M2400S Rev A

Page 42
Management
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 M900S 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 from 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 on the Ethernet port
• aptrafficRfInOctets – Number of octets of payload received on the RF port
• aptrafficRfOutOctets – Number of octets of payload transmitted on 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.
a. trango_m2400sap_1p0.mib – M2400S AP MIB file
b. trango.ico – M900S AP icon
c. autoico.txt – instruction file (Selects Trango icon automatically during initial set-up.)
d. readme.pdf
3. Copy trango_m2400sap_1p0.mib file to C:\Program Files\SNMPc Network Manager\mibfiles
4. Copy autoico.txt file to C:\Program Files\SNMPc Network Manager\mibfiles
5. Copy trango.ico file to C:\Program Files\SNMPc Network Manager\bitmaps
6. The MIB needs to be compiled into the SNMPc database

Management
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)
