Description
Hopper Plus 120-24 Wireless Ethernet Bridge
The Hopper Plus 120-24 is a wireless Ethernet bridge that provides high-speed, wireless
connectivity at a fraction of the cost of wired solutions. It uses multi-code direct sequence
spread spectrum technology over the license-exempt, 2.4 - 2.4835 GHz ISM radio band.
The maximum data rate is 12.0 Mbps.
The Hopper Plus 120-24:
¥ provides wireless connectivity at speeds up to eight times faster than regular T1 lines,
making the Hopper Plus ideal for providing high-speed Internet access or for wirelessly
extending existing communications infrastructures.
¥ supports point-to-point and point-to-multipoint networks. Contentionless polling ensures
efficient access to remote data networks.
¥ is self-contained and easy to use. Simply connect a Hopper Plus 120-24 to each LAN
segment, and the unit automatically learns where nodes are located on the network and
performs dynamic packet filtering to ensure the local LAN traffic does not overload the
wireless connection.
Making a Wireless Bridge
The simplest example of using the Hopper Plus 120-24 is a point-to-point wireless bridge,
which requires a minimum of two units: a base unit and a remote unit. The units make a
high-speed wireless communication link between two wired network segments.

About Hopper Plus Units
Base Station: A Hopper Plus 120-24 can operate as a remote unit or a base station,
however, at least one unit in the network must be configured as a base. A base station is
the central control unit of the wireless network. The base station polls all remote units and
controls how traffic is routed to and from remotes. The base usually connects to a major
access point of the wired network. The antenna of the base station must be capable of
transmitting and receiving radio signals to and from all the remote units in a system. If
remotes are spread over a large area, an omni-directional antenna is usually required.
Remote Units: Remote units link wired segments of the network wirelessly to the main
network (via the base station). Remotes can limit the amount of data passed by the remote
(a function called throttling), and they can filter specific data packets. Because remote
units need to communicate only with the base station, their antennas can be more
directional and have higher gains than base antennas.
Repeaters: A base unit can also be configured as a repeater. A repeater is needed when
remote units cannot communicate directly with each other, but direct transfers of data
between them are necessary (as in a true WAN). When configured as a repeater, the base
station passes data packets between remote stations based on the remote group status and
the MAC (Media Access Control) address filter. Remote stations ignore the packets they
hear from other remotes, and listen only to the repeated packets from the base. See Setting
Repeater Mode (Base Station Only), page 49 for more information.

Installation
Conﬁguring a Unit as a Base
Hopper Plus 120-24 units are delivered from the factory configured as remote units. To
make a wireless bridge, you need to configure one unit as a base unit (base station). All
other units in the wireless network can remain configured as remote units (so you do not
need to change the "station type" of remotes). No user software is required to install a unit.
To conﬁgure one unit as a base unit
1. Connect a PC to the MANGAGEMENT port to the Hopper Plus unit that will be the
base unit.

Testing Basic Operation
Wi-LAN recommends that you bench test units before placing them the field. You should
first perform a standalone test, then test the bridge as part of a simple network.
Once one unit has been set to a base unit, it can then be used to test all other remote units
without making configuration changes to the remotes.(Units are shipped from factory
configured as remotes).
Performing a Bench Test
To perform a bench test of the bridge
1. Ensure that you have configured a unit as a base unit.
2. Ensure that the station type of all other units is Remote Unit. See Setting the Station
Type, page 42.
Version 1.0 Rev B - 08/00

Installation
3. Locate base unit and one remote unit at least twenty meters apart with a clear line of
sight between them.
4. Attach the provided indoor antenna to the antenna port of each unit, and orient the
antenna vertically.

6. Observe the AIR LED of each unit and look for normal status. A normal status is
indicated when the AIR LEDs on the base and the remote unit are both orange. The
status of the AIR LED is indicated as follows.
Orange (both stations)
The stations are continuously sending and receiving
sync packets.
Red (base station)
The stations are conﬁgured incorrectly, and the base
station is transmitting without receiving
acknowledgment.
Green (remote station)
The stations are conﬁgured incorrectly, and the remote
station is receiving packets to which it cannot respond.
Off
Nothing is being received (by the remote) or transmitted
(from the base).
Note: If antennas are too close together, the strong transmit signal will cause distortion at
the receiveing unit. You can fine-tune antennas by physically moving the antenna. When
the remote antenna is correctly aligned, the AIR LED is orange, indicating that data from
the base station is being received and acknowledged.
7. Run the Link Monitor test on the remote unit. See Setting Link Monitor Remote Station
Rank (Base Station Only), page 38. Check for RSSI below 40% and BER = 0. If you
have problems ensure that the unit is configured to its basic default settings or contact
Wi-LAN customer support.
8. Disable Link Monitor.
9. When both AIR LEDs are orange, power down both units and perform the simple
network test. See Performing a Simple Network Test, page 13.

Testing Basic Operation
Performing a Simple Network Test
To perform a simple network test
1. Connect one Hopper Plus 120-24 to the LAN.
2. Connect a PC from your network directly to the other Hopper Plus 120-24 (connect
with a 10/100 BaseT crossover cable if no hub is used).
Note: Cabling between 10/100 BaseT nodes is generally done through a net-
work hub. To make a direct 10/100 BaseT connection between a Hopper Plus
120-24 and a PC, you need a standard crossover cable (swap pins 1&3; 2&6).

Setting Link Monitor Remote Station Rank
(Base Station Only)
The Hopper Plus can test the RF link while it carries actual data. Link monitor sends test
data along with the message data (the amount of data sent is determined by the setting of
the Link Monitor Period). See Setting the Link Monitor Period, page 36.) The receiving
unit processes statistics and sends the test data and statistics back to the testing unit. The
testing unit then processes and displays statistics for both directions on the link monitor
display. (See Viewing Link Monitor Statistics, page 66 for information about viewing link
monitor statistics).
Note: It is possible to run the link monitor twice over one link by enabling it on the base
and the remote at the same time. This situation should be avoided as it causes needless
overhead.
You can run the link monitor from the base or any remote. When you run the link monitor
from the base station, you must enter the station rank of the remote whose link you wish to
test (rank represents the number of remotes that the base polls). When you run the link
monitor from a remote, the only link that can be tested is to the base, so the station rank is
not configured.
To set the link monitor rank from the base unit

Setting Throttling (Remote Station Only)
Throttling limits the amount of data that passes though a remote Hopper Plus 120-24 unit.
When throttling is enabled, the amount of data passed is equal to the throttling level times
128 kbps, to a maximum of 6.4 Mbps. Throttling applies to both the down link and up link
traffic, so a setting of 128 kbps means the unit can pass 128 kbps in each direction. When
throttling is disabled, the unit allows up to the maximum available bandwidth. The default
setting is to disable throttling.
To enable throttling

Radio Module Conﬁguration
Changing the configuration settings of a Hopper Plus while it operates in a system could
disrupt service. To prevent disruptions when the configuration is being changed, the
Hopper Plus stores configuration information in three different states:
New
The intended conﬁguration changes. Temporary.
Current
The conﬁguration actually running on the unit. Temporary.
Flash
The conﬁguration that was stored last in FLASH memory.
Final conﬁguration is saved to FLASH memory.
To change the current conﬁguration of the radio module
1. Set the Config Test Minutes. See Setting Config Test Minutes, page 48.
2. Make new configuration changes with the Radio Module Configuration menu. These
changes are stored in the New state, but the radio uses the Current state configuration
until it is rebooted with new configuration.
3. Reboot the unit following the steps in Rebooting and Saving RF Configurations, page
53. The unit runs the new configuration, and the old configuration is retained in
FLASH.
4. If the new configuration works as intended, then the changes can be saved to FLASH.
See To save current configuration to FLASH, page 54.
If the new configuration disrupts communications, then the configuration stored in
FLASH is restored after a timeout has elapsed. The unit can be re-configured and
tested until the unit works as intended.

Setting the Station Rank
For a base station, rank is the number of remotes that the base polls (regardless of the
actual number of remotes in the system). The base station rank should equal the number of
remotes so the base does not waste time polling nonexistent remotes.
For a remote unit, rank is a unique number that identifies the remote to the base station.
The base station polls remote units sequentially from rank 1 to the base unit s station rank,
then repeats the process.

Setting Conﬁg Test Minutes
Since there is a chance that RF configuration changes will disrupt communications, each
unit returns to its pre-configuration state after a timeout (unless the changes are saved to
FLASH before the timeout). This timeout is set with the Config Test Minutes parameter,
which can be set from 1 to 120 minutes.
When testing, the configuration test timeout value should be set before any other radio
module changes are made, so that the correct value is used if other changes cause the unit
to lock up. If you set the timeout too low, then you may not have time to save the changes
to FLASH. If you set it too high, then you will have to wait a long time for the unit to
reboot after a change that disrupts service.
Note: All units in the same network must have this setting set to the same value.

Setting System Symmetry Type (Base Station Only)
System symmetry type defines the amount of priority the base unit has when polling the
remotes. The default setting "asymmetric" gives the base unit a time slot after each remote
is polled—an asymmetric system is appropriate when the base is the access point to a large
network.The "symmetric" setting limits the base unit to one time slot for every polling
cycle; a symmetric system is more efficient when the base has data passing requirements
that are similar to the remotes.

Appendix A: Planning Your Wireless Link
To ensure an effective and reliable wireless link, you need to perform some preliminary
network planning before you install any hardware.
These steps include:
¥ determining the physical layout of your planned link
¥ planning your antenna and fade margin requirements
¥ configuring your RF link.
Planning the Physical Layout
Before you install the units, you must determine the physical locations for each
component of the Hopper Plus 120-24 wireless system.
When you plan the physical layout, you need to:
¥ measure the physical distance between each pair of units using GPS, a map, or other
distance measurement method
¥ determine antenna mast height requirements and fade margins
¥ determine cable requirements, including routing, between antenna and unit
¥ calculate the fade margin to determine the reliability of your wireless link
¥ determine environmental requirements
Measuring the Physical Distance Between Units
Use a mapping method to determine the distance between sites, and check the radio path
to identify any obstructions in the site path between the two antennas. Due to the high
frequency and low output power permitted in the ISM bands, no obstructions may exist
between two antennas.
Determining Antenna Requirements
If you plan to install the unit indoors, the rubber duck antenna shipped with the unit may
be adequate. The signal from this antenna can penetrate several walls, although metal
obstructions or building features such as elevator shafts can deflect or inhibit radio waves.
Empirical testing is advised in this case because all interiors are unique.
If you plan to install the antennas outdoors you will need to consider
¥ obtaining permission from building owners if you intend to install your antenna on a
rooftop
¥ the height of the antenna required to ensure a radio Line of Sight between two
antennas that define the RF link
Version 1.0 Rev B - 08/00
71
Appendix A: Planning Your Wireless Link
¥
¥
¥
potential wind load and ice loading impact on the antenna
regulatory restrictions, such as height, on antenna mast usage in the identified location
grounding requirements. You must ensure that your antenna is properly grounded for
lightning and installed according to the relevant electrical code for the location.
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 should minimize the length of the coaxial
cable because the longer the cable is, the greater the cable losses are. You need to know
the required cable lengths before you install the unit.
Note: You should use surge suppressors at the point of cable entry into the building.
Calculating Fade Margins
You can calculate the fade margin of your wireless link after you ve identified the antenna
requirements. The fade margin enables you to predict the reliability of your wireless link.
See Calculating Path Loss on page 78 for more information about fade margins.
Determining Environmental Requirements
Hopper Plus 120-24 units must be located in a weatherproof environment with an ambient
temperature between 0… and 40… Celsius, and humidity from 0 to 95% non-condensing.
Consider the building, heating, and air conditioning required to ensure that the unit
operates within these conditions.
Optimizing the RF Link
Overview
This section explains how to obtain optimal performance from your RF link. Proper path
planning ensures that each end of the RF link receives sufficient signal power to maintain
a desired Bit Error Rate (BER). The effectiveness and reliability of your RF link depends
on the following:
¥ antenna gain, beamwidth, F/B ratio, and cross-polarization discrimination
¥ distance between antennas and obstructions in the RF path
¥ above-ground height of the antennas
¥ length and type of coaxial cable connecting the Hopper Plus 120-24 and the antenna
The above factors will be used to calculate your link budget. The 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 decibels (dB).
72
Version 1.0 Rev B - 08/00
Optimizing the RF Link
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:
P1
dB = 10 × log  -------
 P2
dBd
The gain or loss of an antenna reference to a standard dipole.
Gain of a Standard Dipole (dBd) = 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 milliwatt. This is an
absolute measure of power rather than a relative measure
such as a gain or a loss.
The following variables are used to calculate the link budget:
Variable
Description
System Gain
The maximum path loss that the system can support
for usable data transmission.
EIRP (Effective Isotropically
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.
Receiver 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
coaxial 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.
Version 1.0 Rev B - 08/00
73
Appendix A: Planning Your Wireless Link
Working with System Gain
The system gain of a radio system is the difference between the transmitted power and a
receiver s sensitivity threshold. The system gain of the Hopper Plus 120-24 is:
74
Formula:
System Gain = Transmission Power - Receiver Sensitivity @ 10-6 BER
Variables:
Hopper Plus 120-24
Tx Power
Receiver Sensitivity =
18.5 dBm
- 83 dBm (receiver sensitivity @ 10-6 BER)
Calculation:
Hopper Plus 120-24
18.5 dBm - (-83) dBm = - 101.5 dB
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,
Wi-LAN recommends that the system gain plus all antenna gains be
greater than the sum of all losses by a factor of 15 dB. This factor is
known as the fade margin.
Version 1.0 Rev B - 08/00
Optimizing the RF Link
Calculating EIRP (Effective Isotropically Radiated Power)
EIRP 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. Unlike the Tx output
power of the devices, EIRP is subject to both antenna gain and cable losses. Many antennas provide a
directional gain, which can increase the effective radiated power. Losses such as cable
losses subtract from this amount. You calculate the EIRP as follows:
Formula:
EIRP = Tx Power (dBm) - Cable Losses (dB) - Connector Losses
(dB) + Antenna Gain (dBi)
Note:
The FCC regulatory body has set the EIRP limit to +36 dBm for
point-to-multipoint applications per FCC 15.247(b)(3)(i).
For point-to-point applications, the FCC EIRP can be 3 dB higher
than +36 dBm for every 1 dB less Tx power below 30 dBm.
Industry Canada speciﬁes the EIRP limit to ≤+36 dBm as per
RSS-210, 6.2.2(p).
In accordance with ETS 300-328 for 2.4 GHz RLANs, the maximum
EIRP shall not exceed +20 dBm, with a maximum SPD (Spectral
Power Density) not exceeding +10 dBm/MHz. Conﬁrmation is
required with the relevant European national radio communications
local authority for deviations from this speciﬁcation.
Version 1.0 Rev B - 08/00
75
Appendix A: Planning Your Wireless Link
Optimizing 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). A
directional antenna focuses the RF energy to the intended station rather than
omni-directionally. This reduces interference from other systems 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 360… 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
15 dB fade margin.
Antenna gain is specified in either dBi or dBd. When an antenna is specified in dBd, add
2.14 dB to the value to convert it to dBi.
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:
Formula:
Attenuation (dB) for 2.4 GHz band = 100 dB + 20log(dkm)
where:
dkm = Distance in Kilometers
100 dB = Pathloss Constant in the 2.4 GHz band
Working with the Fresnel Zone
It is essential that you locate your antennas at maximum above-ground height to ensure
that
1. all ground-based obstructions are cleared from the Line of Sight path
2. the Fresnel Zone is clear of obstructions

Calculating Cable Loss
Cable and connector losses affect the operation of the wireless link and therfore should be
kept to a minimum. The two primary coaxial cable specifications for the Hopper Plus 12024 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:
Cable Type (loss in dB/meter)

Note: 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.
Version 1.0 Rev B - 08/00

Appendix A: Planning Your Wireless Link
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:
Formula:
Path Loss = Tx and Rx Cable Loss + Tx and Rx Connector Loss +
Propagation 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 74 for more information about system gain.
Total antenna gain
is:
Tx Antenna Gain +
Rx Antenna Gain
78
Working with the Fade Margin
The amount by which the system gain plus the total antenna gain exceeds the path loss is
called the fade margin. As calculated, the fade margin is 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 objects that induce multipath interference.
The Wi-LAN recommended fade margin for the Hopper Plus 120-24 is a minimum of
15 dB. The sum of the cable losses, connector losses, propagation losses, and the 15 dB
required fade margin should be less than the sum of the system gain and antenna gain.

Putting everything together, you must satisfy the following equations to have a successful
link:

Formulas:
or
Actual Fade Margin ≥ System Gain + Antenna Gain - Propagation
Loss - Cable Losses - Connector Losses

Antenna Basics
Antennas focus and absorb radio energy in specific directions, depending on their design.
They can be tuned to certain frequency ranges; the Hopper Plus 120-24 antennas must be
tuned to 2.4 - 2.5 GHz.
This section contains some basic information about antenna parameters and how to select
and install antennas for use in your wireless system.
Antenna Parameters
80
Parameter
Description
Gain
• Antennas have a gain associated with them, which is a measure
of their ability to amplify signals in their tuned band.
• Antenna gain is achieved by focusing the signal. A higher gain
antenna has more compressed signal.
dBd vs. dBi
• Antenna gain must be measured over a known reference and is
often expressed as either dBd or dBi.
• dBd is antenna gain referenced over a half-wave dipole which is
an antenna that has a donut shaped radiation pattern.
• dBi is antenna gain referenced over an isotropic radiator which
is a theoretical antenna that radiates equally in all directions
(e.g. the sun).
• Wi-LAN references antenna gain in dBi. The conversion factor
is:
0 dBd = 2.14 dBi
Beamwidth
• The beamwidth of an antenna describes how a signal spreads
out from the antenna, and the range of the reception area.
• Beamwidth is measured between the points on the beam
pattern at which the power density is half of the maximum
power. This is often referred to as the -3 dB points.
• A high gain antenna has a very narrow beamwidth and may be
more difﬁcult to align.
Downtilt or uptilt
• Some antennas have either an associated downtilt or an uptilt.
The tilt further focuses the signal downward or upward with
respect to the horizon.
• A tilt may be either electrically built into the antenna or achieved
mechanically with the mounting gear.
• A downtilt or uptilt may be required when there is a signiﬁcant
deviation between the elevation of the remote site(s) and the
base site.
F/B
• Front-to-back ratio.
• Directional antennas focus the signal in a forward path. This is
achieved by directing the signal in one direction that reduces the
signal in the opposite direction.
• A higher gain antenna typically has a greater F/B ratio.
Version 1.0 Rev B - 08/00
Antenna Basics
Parameter
Description
XPD
• Polarity and Cross-Polarization Discrimination (XPD).
• Antennas have an associated polarity, which is the orientation of
the radiating element with respect to earth.
• Antennas are usually described as vertical, horizontal, or
circularly polarized. The polarity of all antennas used in a
system must be the same.
• Cross-Polarization Discrimination speciﬁes the signal isolation
achieved when the receiving element is perpendicular to the
radiating element. This can be advantageous when co-locating
radio systems.
VSWR
• Voltage standing wave ratio.
• VSWR is the voltage ratio of minimum to maximum across a
transmission line.
• A VSWR of 2.0:1 or less in an antenna is considered effective.
Most antennas have a VSWR of 1.5:1.
• For example, when using a radio with a 4 watt output with an
antenna VSWR of 1.5:1, the reﬂected power will be 160
milliwatts.
Implementation Considerations
Following are some key items to consider when selecting and installing antennas for your
wireless network:
Item
Description
Absorption
• Antennas mounted too close to “soft” objects, such as trees,
may experience a reduction in signal strength due to absorption.
• Absorption is most often encountered in applications installed
during the fall or winter months, and the problem does not
become evident until the spring.
Diffraction
• Diffraction occurs when a radio signal reﬂects or bounces off of
a solid object.
• The level of diffraction could lead to connectivity problems if the
remaining signal level is too low.
• Two types of diffraction are shadowing and multipath.
Shadowing
• Shadowing is a form of diffraction that is typically caused when
antennas are mounted too close to a structure and they lose a
portion of the signal lobe due to reﬂection. The receive antenna
is in a shadowed area.
• To minimize shadowing, ensure that there is adequate height
above structures when mounting antenna equipment.
Multipath
Interference
• Multipath is a form of diffraction in which the reﬂected signal
arrives at the receiver at different times which confuses the
receiver.
• Multipath may be interpreted as interference by the receive
antenna, and can result in bit errors and processing delays.

Appendix A: Planning Your Wireless Link
Selecting Antennas
There are several factors to consider when selecting the right antenna for a wireless
application. Following are some initial questions you should ask before selecting an
antenna:
¥ What is the operating frequency range?
¥ Will this be a point-to-point or point-to-multipoint application? Ensure that you
consider if the application will change in the future.
¥ What are the coverage requirements?
¥ How far is the remote site(s)?
¥ What is the gain requirement?
¥ What is the elevation of the remote site(s) with respect to the base station and will
additional downtilt/uptilt be necessary at either the base or remote site to compensate?
¥ Will there be any obstructions in the path?
¥ Will systems be co-located? What polarity will be used?
¥ What are the regional environmental conditions? For example, is there windloading,
salt air, excessive moisture, ice buildup?
¥ What is the antenna lifetime expectation?
¥ What are the site and mounting options?
¥ What are the restrictions in the locale regarding the effective radiated power permitted
from the antenna?
¥ Will antenna appearance be a factor?

Safety
• Proper grounding of antenna apparatus in accordance with
respective Electrical Code(s) is crucial.
• Wi-LAN recommends using a surge arrestor where the antenna
cable enters the building.
• All installations should be completed by a qualiﬁed and
competent RF technician.
EIRP
• Effective Isotropically Radiated Power (EIRP)
• EIRP is the amount of power that is transmitted to the air from
the antenna.
• EIRP levels depend on the power of the radio transmitter, the
size of the antenna, and the losses incurred in the antenna
cable.
• To remain license-exempt the EIRP must remain under 4 watts
or 36 dBm in Canada and the United States for
point-to-multipoint applications. In Europe, this value is reduced
to 100 mW or 20 dBm.
Note: EIRP = Power out of unit – Power lost in cable + Gain in
power from Antenna
Fade Margin
See Calculating Fade Margins on page 72.
LOS
• Line of Sight (LOS)
• LOS is a football shaped pattern known as the Fresnel Zone,
which must be kept clear of obstructions. See Working with the
Fresnel Zone on page 76 for more information.
• Visual line of sight must be achieved. When standing at the
antenna position, you must be able to see the remote antenna.

¥
¥
¥
antennas for the system have the same polarity (vertical, horizontal, or circular).
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 and entering the installation building.
the coaxial cable is secured to the supporting structure at one meter intervals. This
prevents wind damage and frost loading problems.
the antenna is firmly attached to the mast to prevent it from falling, yet has some
flexibility so you can move the antenna to fine-tune its position.
the coaxial cable is connected to the antenna and to the antenna port on both sides of
the link (base and remote stations).
the antennas are grounded properly.

Antenna Basics
Fine-tuning Antennas
You can fine-tune the antennas by physically moving the antenna. When the remote
antenna is correctly aligned, the AIR LED is orange, indicating appropriate reception and
acknowledgment of sync tokens from the base station. You can use the Receive and
Transmit operating modes to test the link while adjusting the antennas to minimize BER
and lost packets, and maximize received power. You can use the RSSI operating mode to
maximize RSSI.
Once the antennas are adjusted to maximize performance, secure them properly to the
support structures.
Co-locating Units
When Hopper Plus antennas are located on the same mast, you must take care to ensure
the output power from one radio does not overpower another co-located bridge, even if the
units are operating on different channels. Contact Wi-LAN technical support for antenna
and installation assistance when co-locating units.

Appendix D: SNMP MIB
About SNMP MIB
Simple Network Management Protocol (SNMP) Management Information Block (MIB)
software is included with each Hopper Plus unit. It enables you to configure, monitor, and
control units via the Ethernet or air. (SNMP-compatible network management software is
available commercially and as shareware.)
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 used to remotely manage network elements by polling, setting
terminal values, and monitoring network statistics and events. It provides a mechanism for
the exchange of management information in a TCP/IP-based Internet environment.
Community names are used by the SNMP manager to determine access privileges (see
Setting Community Names on page 58).
SNMP consists of three elements.
SNMP Element
Description
Manager
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
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)
Is a database that is accessed by a speciﬁc
set of commands that you 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.

Glossary
absorption
Antennas mounted too close to soft objects, such as trees, may experience a reduction in
signal strength due to absorption. Absorption is most often encountered in applications
installed during the fall or winter months. The problem does not become evident until the
spring.
acquisition code
To minimize the effects of interference, all units in a system use the same acquisition code
so the receivers can distinguish the desired signal from interfering signals.
agent
In an SNMP context, the agent runs on each unit. An agent accepts configuration
commands from the manager and collects network and terminal information specified in
the MIB.
antenna
A device which accepts electromagnetic energy from a circuit or wire and radiates it into
space rather than confining it.
antenna gain
Gain of the antenna over a dipole (dBd) or isotropic (dBi).
¥ Antennas have a gain associated with them, which is a measure of their ability to
amplify signals in their tuned band.
¥ Antenna gain is achieved by focusing the signal. A higher gain antenna has more
compressed signal.
attenuation
Any loss in signal strength, due to resistance, absorption, capacitance, or any
characteristic of the medium or design of the system.
beamwidth
The beamwidth of an antenna describes how a signal spreads out from the antenna as well
as the range of the reception area. Beamwidth is measured between the points on the beam
pattern at which the power density is half of the maximum power. This is often referred to
Version 1.0 Rev B - 08/00
113
Glossary
as the -3 dB points. A high gain antenna has a very narrow beamwidth and may be more
difficult to align.
BER
Bit Error Rate. A percentage of bits per million, showing the number of bits in error
compared to the data bits actually sent.
blocking
Blocking is an operating mode where the radio receives only. Unblocked is the normal
operating mode.
cable loss
The signal loss experienced as it passes through the coax cable. Expressed in dB.
channel
The width of the spectrum band taken by a radio signal, usually measured in
kilohertz (kHz).
coaxial cable
A type of wire where the inner conductor is surrounded by an outer conductor. The outer
conductor serves as an electrical shield.
collision
The situation that exists when two users try to send a signal over the same medium at the
same time, and the signal uses the same frequencies.
conﬁguration menus
The menu based user interface on the Hopper Plus 120-24 that allows the viewing and
configuration of Hopper Plus 120-24 parameters.
contentionless polling
The Hopper Plus 120-24 uses a form of dynamic polling that ignores idle remote stations.
The number of polls that an idle remote is ignored can be set to maximize polling to active
stations.
Cross-Polarization Discrimination
See XPD.
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:
P1
dB = 10 × log  -------
 P2
DB9
A D-shaped connector with 9 pins.
114
Version 1.0 Rev B - 08/00
dBd
dBd is antenna gain referenced over a half-wave dipole which is an antenna that has a
donut shaped radiation pattern.
Gain of a Standard Dipole = 2.14 dBi.
dBi
dBi is antenna gain referenced over an isotropic radiator which is a theoretical antenna
that radiates equally in all directions (e.g. the sun).
Wi-LAN references antenna gain in dBi. The conversion factor is:
0 dBd = 2.14 dBi
dBm
A power measurement referenced to one milliwatt. This is an absolute measure of power
rather than a relative measure such as a gain or a loss.
diffraction
Diffraction occurs when a radio signal reflects or bounces off of a solid object. The level
of diffraction could lead to connectivity problems if the remaining signal level is too low.
Two types of diffraction are shadowing and multipath.
downtilt
Some antennas have either an associated downtilt or an uptilt. The tilt further focuses the
signal either downward or upward with respect to the horizon. A tilt may be either
electrically built into the antenna or achieved mechanically with the mounting gear. An
downtilt or uptilt may be required when there is a significant deviation between the
elevation of the remote site(s) and the base site.
dynamic polling
A polling protocol in which idle units are not polled as frequently as active units. Since
less time is spent polling idle remotes, there are more available resources for active units
and overhead is reduced.
EEPROM
Electrically Erasable, Programable Read Only Memory: Non-volatile memory, but must
be removed from board to be erased.
EIRP
Effective Isotropically Radiated Power. EIRP is the amount of power that is transmitted to
the air from the antenna. EIRP levels depend on the power of the radio transmitter, the size
of the antenna, and the losses incurred in the antenna cable. To remain license exempt the
EIRP must remain under 4 watts or 36 dBm in Canada and the United States for
point-to-multipoint applications. In Europe, this value is reduced to 100 mW or to
20 dBm.
Note: EIRP = Power out of unit — Power lost in cable + Gain in power from Antenna
Version 1.0 Rev B - 08/00
115
Glossary
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.
ETSI
European Telecommunications Standards Institute.
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.
ﬁltering
Filtering in remote stations limits certain data packets.
FLASH
A type of electrically erasable non-volatile memory that can easily be erased without
removal from the board. Using FLASH, Hopper Plus 120-24 units can be upgraded in the
field.
Fresnel zone
One of a (theoretically infinite) number of a concentric ellipsoids of revolution which
define volumes in the radiation pattern of a (usually) circular aperture.
Notes:
¥ The cross-section of the first Fresnel zone is circular. Subsequent Fresnel zones are
annular in cross-section, and concentric with the first.
¥ Odd-numbered Fresnel zones have relatively intense field strengths, whereas
even-numbered Fresnel zones are nulls.
¥ Fresnel zones result from diffraction by the circular aperture.
front to back ratio (F/B)
Directional antennas focus the signal in a forward path. This is achieved by directing the
signal in one direction that reduces the signal in the opposite direction. A higher gain
antenna typically has a greater F/B ratio.
IEEE
Institute of Electrical and Electronics Engineers.
image
An image is a collection of configurations or settings for a particular device. With the
Hopper Plus 120-24, the System Image File contains a collection of configurations that are
used when the unit is rebooted.
interference
Any signal that tends to hamper the normal reception of a desired signal. Equivalent to
jamming except considered non-hostile in origin.
116
Version 1.0 Rev B - 08/00
ISM
Industrial, Scientific, and Medical. It is the family of license-exempt radio bands in North
America and some European countries. It is also referred to as part 15.247 in the FCC
regulation that defines the parameters for use of the ISM band in the U.S., including
power outputs, spread-spectrum, and noninterference.
link monitor
A Hopper Plus 120-24 utility that sends known data over an active system to test the
reliability of the RF link. The link monitor information is overhead, that is, it reduces the
amount of available payload for message data.
LOS (Line of Sight)
LOS is a elliptical pattern known as the Fresnel Zone, which must be kept clear of
obstructions. Visual line of sight must be achieved. When standing at the antenna position,
you must be able to see the remote antenna.
MAC address
Media Access Control address. Alphanumeric characters that uniquely identify a
network-connected device.
Management Information Block
See MIB.
manager
When used in SNMP, 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.
MIB
Management Information Block. 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.
multipath interference
Multipath is a form of diffraction in which the reflected signal arrives at the receiver at
different times which confuses the receiver. Multipath may be interpreted as interference
by the receive antenna, and can result in bit errors and processing delays.
OID nodes
Object Identifier Nodes. These are the individual nodes in a MIB. See SNMP and MIB.
Version 1.0 Rev B - 08/00
117
Glossary
overhead
Anything that reduces the payload capacity of a system is overhead, even if serves a useful
function. The link monitor data is used to determine transmission statistics, but it reduces
the message carrying capacity of the Hopper 120-24 system and is considered overhead.
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.
point-to-multipoint
A wireless system where one base unit communicates with many remote units. The base
unit polls all the remotes, and data passes between units to complete the network.
point-to-point
The simplest wireless system consisting of a base and one remote.
polling
The base unit in a Hopper Plus 120-24 point-to-multipoint system handles multiple
remotes by polling each one sequentially. When a base polls a remote, data exchange
between that remote and the base takes place. The remote cannot exchange information
with the base until it is polled again.
propagation loss
The signal loss experienced as it travels through the air. Expressed in dB.
RF
Radio Frequency. A system of communication using electromagnetic waves propagated
through space. Because of varying characteristics, radio waves of different lengths are
used for different purposes and are usually identified by their frequency.
RS-232
Standards for serial communications, which define the voltages, currents, data rates, and
other factors about the signals to be used, as well as single-ended, differential, multi-drop
operation.
RSSI
Received Signal Strength Indicator. Strength of received signal expressed in dB. The
Hopper Plus 120-24 measures RSSI as a fade margin value.
sensitivity
The minimum signal strength required for usable performance. Expressed in dBm.
118
Version 1.0 Rev B - 08/00
shadowing
Shadowing is a form of diffraction that is typically caused when antennas are mounted too
close to a structure, and they lose a portion of the signal lobe due to reflection. The receive
antenna is in a shadowed area. To minimize shadowing, ensure that there is adequate
height above when mounting antenna equipment to a structure.
SNMP
Simple Network Management Protocol. 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.
spread spectrum
Any of a group of modulation formats in which an RF bandwidth much wider than signal
bandwidth is used to transmit information, resulting in a greater immunity to noise
interference.
system gain
The maximum path loss that the system can support for usable data transmission.
system image ﬁle
The Hopper Plus 120-24 uses system image files to store system configuration settings.
The default system image file is called factory-image and is when the Hopper Plus is
first powered up.
telnet
An Internet communications protocol that enables a computer to function as a terminal
working on a remote computer. A computer with a network connection to a Hopper Plus
120-24 system can Telnet to any of the (configured) Hopper Plus 120-24 units and access
their configuration menus.
throttling
Throttling limits the amount of data that a remote station passes.
uptilt
See downtilt.
XPD (Cross-Polarization Discrimination)
Refers to polarity and Cross-Polarization Discrimination. Antennas have an associated
polarity, which is the orientation of the radiating element with respect to earth. Antennas
are usually described as being vertical, horizontal, or circularly polarized. The polarity of
all antennas used in a system must be the same. XPD specifies the amount of signal
Version 1.0 Rev B - 08/00

Glossary
isolation achieved when the receiving element is perpendicular to the radiating element.
This can be advantageous when co-locating radio systems.
VSWR (Voltage Standing Wave Ratio)
VSWR is the voltage ratio of minimum to maximum across a transmission line. A VSWR
of 2.0:1 or less in an antenna is considered effective. Most antennas have a VSWR of
1.5:1. For example, when using a radio with a 4 watt output with an antenna VSWR of
1.5:1, the reflected power will be 160 milliwatts.
