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 carrier-
class 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-to-
point 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.

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
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

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.

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

(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.

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.
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.

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:
Login:
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:
Login: root
Password: 1234
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
InfiNet Wireless R5000 Technical User Manual
Copyright © 2004-2010 by InfiNet Wireless
40
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.
InfiNet Wireless R5000 Technical User Manual
Copyright © 2004-2010 by InfiNet Wireless
41
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».
InfiNet Wireless R5000 Technical User Manual
Copyright © 2004-2010 by InfiNet Wireless
42
«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‘ IP-
address 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:
InfiNet Wireless R5000 Technical User Manual
Copyright © 2004-2010 by InfiNet Wireless
43
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:sec ret@192.168.1.1/ var/conf/ test.c fg
“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
InfiNet Wireless R5000 Technical User Manual
Copyright © 2004-2010 by InfiNet Wireless
44
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:
rfc onfig rf4.0 freq 5260 bitr 24000 sid 01010101
Additional important parameters and settings for the radio interface:
rf4.0 – radio interface name in this case. In order to obtain
radiointerface name either see the ODU/Device labeling or execute
―ifc -a‖ command.
pwr – 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
InfiNet Wireless R5000 Technical User Manual
Copyright © 2004-2010 by InfiNet Wireless
45
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:

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.

V. Link Configuring
1. Preliminary decisions
Speed selection
Overall link performance is greatly depends on the right speed selection. Wrong
speed of a radio link in most cases lowers its performance characteristics. In the
result subscribers are getting bad services.
IW MINT architecture makes speed selection process fully automatic. Using IW
proprietary Link Forecasting and Active Testing algorithms MINT chooses the
optimal radio transmission speed individually for each connected subscriber
device.
Therefore, main recommendations for speed selection are:
enable autobitrate mechanism and set maximal available bitrate
on the radio interfaces of all the devices.
To estimate the real speed of a device prior to its installation and
deployment use RangeCalculator 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 provides with a maximal connection performance. Power
decreasing is logical when the maximal speed is already reached and there are
no repeats. In this case an 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).
InfiNet Wireless R5000 Technical User Manual
Copyright © 2004-2010 by InfiNet Wireless
49
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:
InfiNet Wireless R5000 Technical User Manual
Copyright © 2004-2010 by InfiNet Wireless
50
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.
InfiNet Wireless R5000 Technical User Manual
Copyright © 2004-2010 by InfiNet Wireless
51
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: speed in
kilobits per second, speed in 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

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
InfiNet Wireless R5000 Technical User Manual
Copyright © 2004-2010 by InfiNet Wireless
53
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:
muffer <IF-NAME> mac2
Statistics
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.
InfiNet Wireless R5000 Technical User Manual
Copyright © 2004-2010 by InfiNet Wireless
54
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 c lear
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
InfiNet Wireless R5000 Technical User Manual

55
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.
InfiNet Wireless R5000 Technical User Manual
Copyright © 2004-2010 by InfiNet Wireless
56
If the interface has several aliases the statistics is still measured for
physical interface in a whole. For example, see rf4.0 or eth0 interfaces
above. The numbers shown in 4 right columns correspond in physical
interface.

make extended diagnostic and optimization of this link. To do this just mouse-
click on the row containing data of the wireless link you want to test (as on the
picture shown below):
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:
InfiNet Wireless R5000 Technical User Manual
Copyright © 2004-2010 by InfiNet Wireless
72
―Start Test‖/‖Stop Test‖ buttons at the bottom of the page start/stop the
alignment test.
―Back‖ button returns to the ―Device Status‖ page.
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.
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:
InfiNet Wireless R5000 Technical User Manual
Copyright © 2004-2010 by InfiNet Wireless
73
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.
The Input Signal stripe may itself change the color indicating the quality of the
received signal (EVM). The possible stripe colors are:
Green – signal quality is good
Yellow – signal quality is worse but acceptable
Red – signal quality is bad.
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‖:
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, Input
Signal stripe color should be green.
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 should be applied to both (Local and Remote)
sections.

VII. Recommendations
1. Using InfiNet devices for High Speeds
Using InfiNet devices on speeds 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 speed on the radio interface and switch on autobitrate function.
This will allow the system automatically and dynamically determine the most
appropriate speed 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 speed/less range
(without amplifiers) or optimize base station for more range/less speed (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
speeds 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 speed (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 speed does not influence the overall working
conditions and network performance;
Increasing receive speed does worsen noise immunity and network
performance.
Every step in speed 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 speed difference between upstream and
InfiNet Wireless R5000 Technical User Manual
Copyright © 2004-2010 by InfiNet Wireless
82
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 speed 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 speed of ―bad subscriber‖.
5. WANFleX/MINT channel reservation
Channel reservation in InfiNet Wireless equipment can be done using several
ways. MINT-network itself determines which available channels to use for data
transmission. MINT algorithms are gathering data and perform calculations to
find out the channel with the best parameters to use. Such calculations are done
fully automatically; moreover, MINT dynamically reconfigures network settings
and used channels according to environment conditions changes.
To perform channel reservation outside MINT-network, for example, in some
wired segment of the network connected to Ethernet interface of IW device,
STP/RSTP (Spanning Tree Protocol/Rapid Spanning Tree Protocol) are realized in
the system. These protocols are used in a switch mode and should be configured
using ―stp‖ option of the ―switch‖ command.
6. 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.
