Overview of the I.WiLL™ 300-24 Access Point
The I.WiLL™ 300-24 Access Point (300-24) is the first Wi-LAN product based on the
Wide-band Orthogonal Frequency Division Multiplexing (W-OFDM) technology. With a
peak data rate of 30 Mbps in 25 MHz of bandwidth, the 300-24 demonstrates the
industry’s most efficient use of bandwidth. The Dynamic Time Allocation technique
allocates variable time slots to busy stations when needed. Valuable bandwidth is not
wasted allocating time to idle stations.
The 300-24 operates in the 2.4-2.4835 GHz license-exempt ISM band allowing you to
provide wireless networking connectivity at a fraction of the wire, cable, or fibre
networking costs. You can manage, configure, and monitor the entire wireless network
through the RS-232 management port, SNMP, or telnet.

Version 1.1 - 01/04/00 7
The Back Panel
Following is an illustration of the back panel:
Back Panel Description
Following are descriptions of the items on the back panel:
Item Description
10/100 BaseT Ethernet
Connector (RJ45 connector) The RJ45 connector uses a standard 10/100BaseT
pin out. The connector auto-negotiates the level
requirements; it automatically sets the network media
support level.
Note: Cabling between 10/100baseT nodes is usually
through a network hub. To make a direct
10/100baseT connection between a 300-24 and a PC,
use a standard ethernet crossover cable.
DB9 Serial Port
(configuration management) Enables you to configure the 300-24 using the RS-232
Serial Port Interface. Only Data Transmit, Data
Receive, and Ground are used (pins 2, 3, and 5
respectively) - straight-through cable.

Grounding the 300-24
If the power cable used in your installation does not have adequate grounding, or if the
grounding does not meet your installation requirements, you will need to ground the unit
using the ground screw located on the back of the unit. This might occur if you you are
installing the unit on a rack, where solid chassis grounds are mandated by the installation
specialists. The ground wire should be 18 gauge or better and the other end of the wire
should be connected to the rack in the case of a rack mounted installation, or to the
customer’s facility grounding system. Following is an enlarged view of the ground screw
identified in The Back Panel on page 7:
When you ground the unit, you need to insert the ground wire into the hole for the ground
wire and then tighten the ground screw to secure the wire.
With a separate ground installed, the 300-24 may have a better earth ground than the local
AC power outlets; an isolation transformer or laptop PC may be required if ground loop
noise becomes troublesome. Proper electrostatic precautions must be followed.

Completing Pre-Installation
Overview
Before you install the I.WiLL™ 300-24 Access Point (300-24) you must perform certain
preliminary steps to ensure an effective and reliable wireless link. These steps include:
• gathering your required installation tools, accessories, and power supplies
• determining the physical layout of your planned link
• planning your antenna and fade margin requirements
• pre-configuring the stations
• bench testing the units in a controlled environment
Each of these steps is described in this section.
Installation Requirements

• I.WiLL™ 300-24 Access Point Installation and Configuration Guide
• Wi-LAN Documentation CD
• Warranty Card
If any of the above items are not included in the 300-24 shipping package, please contact
Wi-LAN customer support. See Customer Support on page 3 for information on how to
contact Wi-LAN.
Planning the Physical Layout
Before you install the units, you must determine the physical locations for each
component of your 300-24 system. When you plan the physical layout, you will need to:
• use a GPS, map, or other distance measurement method to determine the physical
distance between each unit
You must have a professional installer assess and calculate the following:
• the antenna mast height requirements and fade margins
• the cable requirements including routing, between antenna and unit
• the fade margin to determine the reliability of your wireless link
• the weatherproofing requirements
Determining the Physical Distance Between Sites
Before you install the units, use a mapping method to determine the distance between your
sites. When you determine the distance, you must check the radio path to identify any
obstructions in the site path between radio locations. You can contact a Wi-LAN
applications engineer to confirm that you have planned an effective radio layout. See
Customer Support on page 3 for more information about contacting Wi-LAN.
Working with Antennas
If you are installing the unit in an indoor setting, the antenna packaged with the unit will
be sufficient for indoor wireless communications. If you are installing the unit in an
outdoor location, a professional installer must calculate the required mast height to ensure
effective communication between your radio links. When installing an outdoor antenna,
the professional installer should consider:
• the required height of the antenna to ensure a clear line-of-site between the RF links
• regulatory restrictions, such as height, on antenna mast usage in the identified location
• obtaining permission from building owners if you intend to install your antenna on a
rooftop
• potential wind load and ice loading impact on the antenna
• grounding requirements. The antenna must be properly grounded for lightening in
accordance with the relevant electrical code for the installation location.
See Working with Antenna Gain on page 19 or see the 300-24 Product Specification for
more information about installing and selecting antennas in outdoor locations.
Due to the high
frequency and low
output powers
permitted in the ISM
band, no
obstructions can be
tolerated between
two antennas.
You should use
lightening arrestors
to ground your
outdoor antenna,
cables, and support
structures.
![](/img.php?id=91098&img=bg11.png)
Pre-configuring the Stations
Version 1.1 - 01/04/00 11
Determining Cable Requirements
If you are installing the antenna in an outdoor location, you will require 50 ohm coaxial
cable to connect the unit to the antenna. You must minimize the length of the cable
between the unit and antenna; the longer the cable length the greater the dB loss. You must
calculate the required cable lengths before you install the 300-24.
Notes:
• You should use surge suppressors at the point of cable entry into the building.
• All cabling work must be carried out by a professional installer.
Working with Fade Margins
Once you’ve identified the physical locations of your antennas, the height of the antennas,
and the cable length required, you can calculate the fade margin for your wireless link.
The fade margin enables you to predict the reliability of your wireless link. See
Calculating Path Loss on page 22 for more information about fade margins.
Note: The fade margin work must be carried out by a professional installer.
Assessing the Weatherproofing Requirements
All 300-24 units must be located in a weatherproof environment with an ambient
temperature between 0º and 30º Celsius. You must consider the building, heating, and air
conditioning requirements to ensure that the unit operates within these conditions.
Pre-configuring the Stations
Typically, the physical layout of a 300-24 system involves significant distances between
units. To ensure the efficiency of your wireless links you must pre-configure the
following:
•a base station
• remote stations
• the polling list
You must assign each 300-24 unit a unique RF Station ID and configure the polling list
before the unit will function properly. These steps must be completed and verified before
you install any units.
Pre-configuring Stations
You must designate each 300-24 unit as a base or remote station and assign each 300-24
unit with a unique RF Station ID.
Use surge
suppressors at the
point of cable entry
into your building.

Bench Testing the 300-24
Before you deploy the 300-24 unit into a network configuration, you should familiarize
yourself with the equipment by bench testing the unit in a controlled environment.
The receiver portion of the 300-24 unit is extremely sensitive, and the high sensitivity of
the radio receiver can make testing in small environments difficult. Close proximity of the
transmitter will overwhelm the radio’s receiver. When you conduct your bench test,
ensure that there is five feet between the two units.
You will need the following equipment to bench test the unit:
• 2 x portable or laptop computers with functioning 10/100 Ethernet adaptors
• 1 x 5 feet RG58 cables (terminated N Male x SMA Female)
• 1 x 5 feet RG58 cables (terminated N Male x SMA Male)
• 1 x 60 dB attenuation @ 2.44 Ghz (can be accommodated by 2 x 30 attenuators)
• 1 x straight-through RS232 cable DB9 x DB9
• 2 x Ethernet crossover cable
To bench test the 300-24
1. Use one of the Ethernet crossover cables to set up a peer-to-peer network between the
two PCs.
2. Verify network operation by transferring a file between the two PCs.
3. Pre-configure each of the 300-24 units. Refer to Pre-configuring the Stations on page
11 for instructions on pre-configuring the units.
4. Insert the attenuation between the two RG58 cables.
5. Connect the opposite ends of the cables to each 300-24 unit. This creates a controlled
path between the units of a known path loss.
6. Perform the link test between the two units. Refer to Viewing the MAC Layer Statistics
on page 39 and Appendix B: Monitor and Test Links on page 75 for information about
link tests.
Using the required cables and attenuation for this bench test, the fade margin should
be 32 dB (± 3 dB).
7. Finally, connect each PC to the 300-24 devices via the Ethernet cables.
8. Transfer a file using the same file transfer protocol used in step 2.
The systems are now tested and configured for deployment into the network system.

Version 1.1 - 01/04/00 17
Determining the RF Link
Overview
This section provides details about how to obtain the maximum range from your RF link.
The effectiveness and reliability of your RF link depends on the following:
• antenna gain
• distance between antennas and obstructions in the RF path
• above-ground height of the antennas
• length and type of coaxial cable connecting the 300-24 and the antenna
The above factors are used to calculate your link budget. The link budget calculation
indicates if your radio link is feasible over a given distance and path and if your RF link
meets regulatory requirements. Link budgets are typically expressed in decibel (dB)
format.
Calculating the Link Budget
Specific calculations must be completed to determine your link budget. This section
describes the calculations and includes definitions of the terms and variables used in the
calculations. The following dB terms are used in this section:
Term Description
dB Decibel. A relative measure of power used to specify power
gains and losses. The difference in power P1 and P2
expressed in dB is:
dBd The gain or loss of an antenna reference to a standard dipole.
Gain of a Standard Dipole = 2.14 dBi.
dBi The gain or loss of an antenna referenced to an isotropic
(theoretical point source) radiator. This measure is used with
only antennas, as it quantifies gain or loss of a physical
radiator with respect to a theoretical one.
dBm A power measurement referenced to one milli-Watt. This is an
absolute measure of power rather than a relative measure
such as a gain or a loss.

Determining the RF Link

Link Budget Variables
You will use the following variables when you calculate the link budget:
Working with System Gain
Proper path planning ensures that each end of the RF link receives sufficient signal power
to maintain a desired Bit Error Rate (BER). The system gain of a radio system is the
difference between the transmitted power and the receiver’s sensitivity threshold. See Link
Budget Variables on page 18 for definitions of these terms. Using this relationship, the
system gain of the 300-24 is:
Variable Description
System Gain The maximum path loss that the system can support
for usable data transmission.
ERP (Effective Radiated
Power) The power radiating from an antenna taking into
account the output power from the transmitter,
connector losses, cable losses, and the antenna
gain.
Sensitivity The minimum signal strength required for usable
performance. Expressed in dBm.
Antenna Gain Gain of the antenna over a dipole (dBd) or
theoretical (dBi).
Propagation Loss The signal loss experienced as it travels through the
air. Expressed in dB.
Cable Loss The signal loss experienced as it passes through the
coax cable. Expressed in dB.
Path Loss The total loss from one end of the path to the other.
This includes propagation losses, cable losses, and
any other losses that impact the system
performance.
Formula: System Gain = Tx Power - Rx Sensitivity
Variables: Tx Power = 15dBm
Receiver Sensitivity = -78dBm nominal for quasi-error free
(BER 10-9) operation
Calculation: 93dB = 15dBm - -78dBm
More info: To ensure reliable communications, the system gain plus all antenna
gains must be greater than the sum of all losses. For a reliable link it
is recommended that the system gain plus all antenna gains be
greater than the sum of all losses by a factor of 13dB. This factor is
known as the Fade Margin.
![](/img.php?id=91098&img=bg19.png)
Calculating the Link Budget
Version 1.1 - 01/04/00 19
Calculating ERP (Effective Radiated Power)
ERP is the power radiating from an antenna taking into account the output power from the
transmitter, the connector and cable losses, and the antenna gain. Because many antennas
can provide a directional gain, the effective radiated power can increase. Losses, such as
cable losses can subtract from this amount. You calculate the ERP as follows:
Note: All ERP work must be completed by a professional installer.
Working with Antenna Gain
To ensure the best range and interference suppression, the external antenna should be
directional, focusing the radio energy in one direction (toward the other end of the link).
The direction can be azmuthal or a horizontal radiation angle. A directional antenna
focuses the RF energy to the intended station rather than omni-directionally. This reduces
interference from other systems that are operating at the same frequency.
Note: In some situations, you may want to use an omni-directional antenna in your
system design. For example, you would use an omni-directional antenna for a base station
with remote sites situated in a 360º path around it.
When you select an antenna, pay particular attention to the gain specification. When you
select an antenna for a remote station, select an antenna with a gain that provides at least
13dB Fade Margin.
Antenna gain is specified in either dBi or dBd. When an antenna is specified in dBd, add
2.14dB to the value to convert it to dBi.
Note: All antenna gain work must be completed by a professional installer.
Formula: ERP = Tx Power (dBm) - Cable Losses (dBm) - Connector Losses
(dBm) + Antenna Gain (dB)
Note: The FCC regulatory body has set the ERP limit to +36dBm for fixed
point-to-point applications per FCC 15.247(b)(3)(i).
Industry Canada RSS-139, Annex B specifies the maximum
transmitter output at +30dBm, with a maximum EIRP (Equivalent
Isotropically Radiated Power) at +36dBm for multi-point
configurations and a maximum EIRP of +53dBm only for licensed
point-to-point applications.
In accordance with ETS 300-328 for 2.4GHz RLANs, the maximum
EIRP shall not exceed +20dBm, with a maximum SPD (Spectral
Power Density) not exceeding +10dBm/MHz. Confirmation is
required with the relevant European national radio communications
local authority for deviations from this specification.
Unlike the Tx output
power of the
devices, ERP is
subject to both
antenna gain and
cable losses.

Determining the RF Link
20 Version 1.1 - 01/04/00
Calculating Propagation Loss
The propagation loss is the attenuation (reduction) in RF signal energy as it travels
through space. In most wireless systems, losses through space are the major contributor to
signal attenuation. When you know the intended installation locations of the base and
remote stations, determine the physical line of sight distance and then calculate the RF
attenuation as follows:
Note: All propagation loss work must be completed by a professional installer.
Working with the Fresnel Zone
It is essential to locate your antennas at maximum above-ground height to ensure the most
effective and reliable link. Achieving maximum above-ground antenna height means that:
• all ground-based obstructions are cleared from the line-of-sight path
• the Fresnel Zone is clear of obstructions
Formula: Attenuation (dB) = 100dB + 20log(dkm)
where:
dkm = Distance in Kilometers
100dB = Pathloss Constant
Note: The FCC regulatory body has set the ERP limit to +36dBm for fixed
point-to-point applications per FCC 15.247(b)(3)(i).
Industry Canada RSS-139, Annex B specifies the maximum
transmitter output at +30dBm, with a maximum EIRP (Equivalent
Isotropically Radiated Power) at +36dBm for multi-point
configurations and a maximum EIRP of +53dBm only for licensed
point-to-point applications.
In accordance with ETS 300-328 for 2.4GHz RLANs, the maximum
EIRP shall not exceed +20dBm, with a maximum SPD (Spectral
Power Density) not exceeding +10dBm/MHz. Confirmation is

Calculating the Link Budget
Version 1.1 - 01/04/00 21
The Fresnel Zone is the expansion of the RF signal radio angles in the vertical plane near
the middle of the RF path. Following is a basic illustration of the Fresnel Zone concept:
The Fresnel radius is calculated as follows:
Calculating Cable Loss
The wireless link is subject to implementation losses such as cable and connector losses.
The two primary coaxial cable specifications for the 300-24 are:
• cable must be 50 ohms nominal impedance
• cable must be of a low loss type
Generally, cable losses are specified in dB/foot or dB/meter. Following is an example of
cable loss ratings:
Notes:
• When you calculate path loss, you should add 1dB at each end of the link to
compensate for connector losses in addition to the cable loss value.
• All cable loss work must be completed by a professional installer.

Determining the RF Link
22 Version 1.1 - 01/04/00
Calculating Path Loss
Path loss describes the total RF attenuation throughout the system from Tx antenna to Rx
antenna. This includes the losses as the RF signal travels through space plus Tx and Rx
cable loss, and Tx and Rx connector loss. Use the following formula to calculate path loss:
Once you know the path loss, you can compare the value to the system gain value. If the
system gain value is greater than the path loss, the link is feasible. See Working with
System Gain on page 18 for more information about system gain.
Note: All path loss work must be completed by a professional installer.
Working with the Fade Margin
The amount that the system gain plus the total antenna gain exceeds the path loss is called
the Fade Margin. The Fade Margin is calculated as the number of dB that the received
signal strength exceeds the minimum receiver sensitivity. You require some level of Fade
Margin for any wireless system. The Fade Margin compensates for RF path fading due to
weather conditions or nearby objects that induce multi-path signaling.
The Fade Margin for the 300-24 is a minimum of 13dB. The sum of the cable losses,
connector losses, propagation losses, and the 13dB required Fade Margin should be less
than the system gain value of 93dB.
Note: All fade margin work must be completed by a professional installer.

Link Budget Example

Link Budget Example
Putting everything together, you must satisfy the following equation to have a successful
link:
Formulas: System Gain + Antenna Gain ≥ Propagation Loss + Fade Margin
+ Cable Losses + Connector Losses
or Fade Margin ≥ System Gain + Antenna Gain - Propagation Loss -
Cable Losses - Connector Losses
where:
System Gain = Tx Power - Rx Sensitivity
Antenna Gains = Tx Antenna Gain + Rx Antenna Gain
Cable Losses = Base Cable Losses + Remote Cable Losses
Connector Losses = Base System Connector Losses + Remote
System Connector Losses
Variables: Desired Fade Margin = 13dB
Tx Power = 15dBm
Rx Sensitivity = -78dBm
Tx Antenna Gain = 9dB
Rx Antenna Gain = 15 dB
Propagation Loss for
desired range of 1km =
Tx Cable Losses
(2m LMR400) = .44dB
Rx Cable Losses
(2m LMR 400) = .44dB
Tx Connector Losses = .5dB
Rx Connector Losses = .5dB
Variable
Calculations: System Gain = 15dBm - -78dBm = 93dBm
Antenna Gains = 9dB + 15dB = 24dB
Cable Losses = .44dB + .44dB = .88dB
Connector Losses = .5dB + .5dB = 1dB
Fade Margin
Calculation: Fade Margin = 93dB + 24dB - 100dB - .88dB - 1dB = 15.12dB
Analysis: We have achieved the goal of a Fade Margin ≥ 13dB.

and connector

Determining the RF Link
24 Version 1.1 - 01/04/00
Verifying a Link Budget
To verify the link budget calculations, from the 300-24 user interface, measure the
Received Signal Strength Indicator (RSSI), Null Depth, and the Fade Margin.
Note: The effects of multi-path are not the same in both directions of a link and you need
to verify the link budget in both directions.
Following are descriptions of the link statistics you need to measure:
Reviewing the Link Statistics
Once you set up the link and select the Mac Layer Statistics window in the user interface,
you can measure the RSSI, Null Depth, and Fade Margin to ensure that the link is
functioning properly. See Appendix B: Monitor and Test Links on page 75 for more
information about monitoring link statistics after the system installation is complete.
You need to measure:
• Null Depth
• Bit Error Rate (BER)
Interpreting the Null Depth
When you interpret the link statistics, you need to subtract the Null Depth from your
budgeted Fade Margin. For example, if you budgeted a 13dB Fade Margin, and you have
an indicated Null Depth of 3dB and an indicated Fade Margin of 10dB, then your
calculations were correct.
Budgeted Fade Margin = Indicated Null Depth + Indicated Fade Margin
where:
13dB = 3dB + 10dB
For small Null Depths, you will typically proceed with a reduced Fade Margin as long as
the number of uncorrected errors is zero, or is incrementing very slowly during peak
traffic periods.
Term Description
Null Depth The difference in strength between the strongest and weakest
OFDM carriers. A Null Depth of more than a few dB indicates the
receiver is experiencing multi-path effects which are partially
canceling the signal. If the Null Depth is more than 3dB, it should
be compensated by moving the receiving antenna or increasing
the antenna gain.
RSSI A numeric indication of the received signal strength in dBm.
You need to verify
the link budget in
both directions: base
station to remote
station and remote
station to base
station.

Verifying a Link Budget
Version 1.1 - 01/04/00 25
Interpreting Bit Error Rate (BER)
The BER after Reed-Solomon Forward Error Correction (RS FEC) can be computed from
the number of uncorrected byte errors and the total number of frames received. The
following constants are used in the calculation:
• 1536 bytes per frame
• 8 bits per byte
• 1.25 bit errors per uncorrected byte error (on average)
From these values, the following formula is structured:
BER = 1.25 x Uncorrected Bytes / (Number of Frames x 1536 x 8)
You need to accumulate approximately 80 byte errors, or 100 bit errors, to receive
statistically significant results. The final test of a good link, is when the BER on the
monitoring computer is 10-9 or better.

Installing Base and Remote Stations
Overview
Once you have determined the RF link and configured the units, you can install the 300-24
units at the site locations.
Installing the Antenna
If your antennas will be located on a support structure, or on top of a tower, you should
have a professional tower worker complete the antenna installation. When you install the
antenna, ensure that:
• the antennas for the system have the same polarity (vertical or horizontal).
• all connectors attaching the coaxial cable to the antenna are properly weatherproofed.
• a drip loop is formed at the building entrance, to prevent water flowing down the
coaxial cable from entering the installation building.
• the coaxial cable is secured to the supporting structure at one meter intervals. This will
prevent wind damage and frost loading problems.
• the antenna is firmly attached to the mast to prevent it from falling, yet has some
flexibility so that you can move the antenna to fine-tune antenna position.
• the coaxial cable is connected to the antenna and to the antenna port on both sides of
the link (base and remote stations).
Note: All antenna installation work must be completed by a professional installer.
Powering Up the Units
Before you power up the units, ensure that the AC Power Level Switch on the back panel
of the unit is set correctly. An incorrect power level setting can cause serious damage to
the unit when it is powered up.
When you successfully power up the unit, the Power LED on the front panel will initially
be orange, and then change to green. See Front Panel LEDs on page 6 for more
information about the LED display.
You need to verify that your hardware and software revision numbers match those on the
data list shipped with the unit. If the numbers do not match, contact Wi-LAN customer
support. See Contacting Customer Support on page 3 for more information about
contacting Wi-LAN.
If you are using
rubber duck or
rubber dipole
antennas, they
should be pointed
vertically (up).

To verify the revision numbers
1. Access the Configuration menus using Telnet or RS-232.
See Accessing the Menus on page 31 for more information about accessing the
Configuration menus and logging into the system.
2. Access the System Revision Information window and verify that the hardware and
software revision numbers shown in the window match those on the data list shipped
with the unit.
See Viewing System Revision Information on page 35 for more information about
viewing the System Revision Information window.
Verifying the RF Port
You can connect two units together back to back via an RF cable to verify the RF port.
You need to ensure that:
• you have at least 70dB of RF attention between the RF ports of the two units.
• the units are at least 10 meters apart.
• you connect a 30dB attenuator directly to each RF port to minimize cross-talk
between units.
• the attenuators have at least a 20dBm power rating.
• you add another 10dB of attenuation between the units, either at one end or in between
the units.
To verify the RF port
1. Access the Configuration menus and verify the following:

sides.
3. From each end of your two unit connection, telnet to the unit from the wire and
wireless sides.
If you can successfully communicate to all units through ping and telnet, your RF port is
verified.
Fine-tuning Antennas
You can fine-tune the antennas by generating consistent steady traffic through the
10/100BaseT port at one end and then, at the receiving end, connecting a PC via the
RS-232 to monitor the link statistics. You can ping the computer to create steady traffic.
Ensure that the link statistics show an adequate Fade Margin and that the Null Depth is
less than 4dB. See Appendix B: Monitor and Test Links on page 75 for information about
monitoring the link statistics.
Reposition the antennas until the required link statistics values are achieved. Once the
antennas have been adjusted to maximize performance, you can secure them properly to
the support structures.
Note: All antenna fine-tuning must be completed by a professional installer.
Completing the Installation Connections
Once the antennas are properly positioned, you need to connect the 300-24 to its LAN
segment. You complete this connection as you would connect a PC to a LAN segment.
Note: Cabling between 10/100baseT nodes is usually through a network hub. To make a
direct 10/100baseT connection between a 300-24 and a PC, use a standard crossover
cable. You must swap pins 1 & 3 and 2 & 6.
Once the connection is complete, the 300-24 unit is ready for network traffic.
The host computers connected to
the units have unique IP addresses

Overview
This section includes some general information about:
• accessing and modifying the configuration settings
• working with the configuration menus to define your 300-24 system settings
You can use the following methods to access and configure the 300-24 units:
•Telnet
• RS-232 Management Port
•SNMP
See Using SNMP on page 65 for information about using SNMP.
You can configure any unit as a base or a remote station. Each system configuration
includes only one base station, however it can include multiple remote stations. If you
need a true wide area network where all sites pass all data packets, the base and remote
stations need to communicate directly with each other. Every station will receive and
decode all packets and a true LAN/WAN network is created from individual segments.

You can access the configuration menus by connecting a PC to the unit through the
RS-232 Serial Port Interface. Typically, you will use this access method to complete
pre-installation configuration and to initially set up your 300-24 system.
To access the configuration menus through the console
1. Disconnect the power from the 300-24.
2. Connect a serial cable from a DB9 serial port on the PC to the RS-232 serial port on
the 300-24.
Note: You can access the RS-232 serial port through the RJ11 connection on the front
of the unit, or through the DB9 connection on the back panel. Adaptors to complete
these connections are shipped with the 300-24.
3. Start a terminal emulation program on the PC.
4. Set the terminal emulation program to emulate a VT100 terminal at:
• 9600 baud
• 8 data bits
• no parity
•1 stop bit
5. Set the terminal program to use the PC serial port that is connected to the 300-24 unit.
6. Power up the unit.
7. Press the spacebar on the keyboard.
The Login menu appears.

Navigating the Configuration Menus
Version 1.1 - 01/04/00 33
Using Telnet
Typically, you will use telnet to access the configuration menus once you have already
completed the initial unit configuration. Because you telnet to the unit’s IP address, you
must have already defined the address before you can telnet to it.
This configuration method is effective when you need to configure a unit from a remote
location.
To use the keyboard up and down arrow keys to navigate the configuration menus, ensure
that the VT100 Arrows feature in your telnet session is enabled.
To access the units through telnet
1. From a VT100 terminal, or emulation, type telnet <IP address>.
Where <IP address> is the address of the unit that you want to configure.
Note: If you are using Microsoft Telnet 1.0 as your terminal emulation application,
see To set the VT100 arrows in Microsoft Telnet below for instruction on setting the
VT100 arrows.
2. Press the Enter key.

Resetting the Statistics
The statistics that appear in the MAC Layer Statistics window and the System Current
Status window are cumulative that is, the values increase over time, until you reset the
numbers back to 0. Typically, you would reset the values when you want to track a
specific occurrence of an event. For example, a unit has had a thermal shutdown, and you
have corrected the cause of the shutdown (a heating/cooling problem). Once the problem
is corrected, you might want to reset the statistics. If the unit shuts down again, a 1 appears
in the statistic window and you can easily determine that a thermal shutdown has
reoccurred.

Using SNMP
Using the Wi-LAN SNMP MIB
Included with each I.WiLL™ Access Point 300-24 unit (300-24), is a Simple Network
Management Protocol (SNMP) permitting configuration, monitoring, and control of:
• base stations via the ethernet
• remote units via the air
Units in remote and hard-to-reach locations can be easily configured, and network
managers can avoid or reduce downtime by monitoring network throughput, packet
collision rates, and interference.
SNMP is a protocol you can use to remotely manage a network element by polling, setting
terminal values, and monitoring network statistics and events. It is the de-facto internet
work management standard, designed to provide a mechanism for the exchange of
management information in a TCP/IP-based internet environment.
SNMP consists of the following three elements:
SNMP Element Description
Manager This element is installed on the network’s
host computer and is controlled by the
network administrator. From the host, the
Manager configures Agents, or polls Agents
for information.
Agent The Agent runs on each unit. An Agent
accepts configuration commands from the
Manager and collects network and terminal
information specified in the MIB.
Management Information Block (MIB) The MIB is a database which is accessed by
a specific set of commands that you can
execute using the SNMP Manager. There is
a standard MIB and a Wi-LAN customized
MIB that stores information relevant to the
operation of a wireless network.

Appendix B: Monitor and Test Links
Overview
You can monitor and test the 300-24 link once it is powered up, has an antenna attached to
it, and is receiving data. All link mode statistics appear in the MAC Layer Statistics
window. See Viewing the MAC Layer Statistics on page 39 for detailed information about
the window. You need to monitor the following three link mode statistics:
•Received Signal Strength Indicator (RSSI)
•Null Depth
•Fade Margin
Monitoring RSSI
The RSSI is the strength of the received signal in dBm (decibels referenced to a
milliWatt). When monitoring the RSSI, ensure that it meets the following statistical
criteria:
In a real application, a fade margin is required to allow for rain fading or other reception
anomalies. See Monitoring Fade Margin on page 76 for more information.
At the other extreme, the receive signal strength cannot be greater than -45dBm or the
receive LNA will saturate. If the RSSI is greater than -45dBm you must add sufficient
attenuation at the remote site to bring the RSSI down to an acceptable level.
Note: Check the back of the 300-24 unit for a label identifying that a RSSI Correction
Factor has been applied to the unit. If so, apply the following correction factor:
Actual_RSSI = RSSI - RSSI_Correction_Factor
RSSI Element Required Measurement
Noise Floor -95dBm
Signal to Noise Ratio 17dBm for quasi error free operation
Quasi Error Free 1 error in 109 bits after forward error
correction
RSSI Required for Quasi Error Free
Operation -95dBm + 17dBm = -78dBm
Receiver Sensitivity -78dBm
![](/img.php?id=91098&img=bg52.png)
Appendix B: Monitor and Test Links
76 Version 1.1 - 01/04/00
Monitoring Null Depth
The Null Depth is the ratio in dB between the strongest OFDM carrier and the weakest
carrier. A Null Depth of greater than 0 dB indicates that there is no multipath reception.
Some multipath is usually present in your link, however adjustments to the position or
location of the receive antenna at the remote site can minimize the Null Depth. In some
cases, you cannot adjust the antenna position and location of the receive antenna at a
remote site.
Monitoring Fade Margin
The Fade Margin is the receive power in excess of the minimum required for error free
operation. See Monitoring RSSI on page 75 for information about receive power.
Fade Margin is computed for you using the following formula:
Thus, we have verified that the correct Fade Margin of 13dB is displayed.
Note: Check the back of the 300-24 unit for a label identifying that a Fade Margin
Correction Factor has been applied to the unit. If so, apply the following correction factor:
Actual Fade_Margin = Fade_Margin - Fade_Margin_Correction_Factor
Performing a Link Test
Linktest is a diagnostic tool for setting up and diagnosing links. Typically, you use linktest
when you:
•initially set up a remote
•diagnose a problem link
Linktest generates pseudo-random packets of information that are transmitted to the
station ID provided. The unit, or station ID, compares the pseudo-random data and
accumulates bit errors, RSSI, Fade Margin, and Forward Error Correction (FEC) statistics.
These statistics and regenerated pseudo-random data are sent in a packet back to the
originating unit. The originating unit then compares the pseudo-random data and at
approximately one second intervals, displays the accumulated statistics in the
configuration menus.
Before you start a linktest, you need the station ID of the base station. See Setting the RF
IDs and Center Frequency on page 58 for information about viewing station ID settings.
Formula Fade Margin = RSSI - Null Depth - Receiver Sensitivity
Example
Variables RSSI = -62dBm
Null Depth = 3dB
Receiver Sensitivity = -78dBm
Fade Margin = 13dB
Calculation Fade Margin = -62dBm - 3dB - -78dBm
Fade Margin = 13dB
