• RF Radiation Exposure and Hazard Warning
• Non-Modification Statement
• Deployment Statement
Class B interference statement
This equipment has been tested and found to comply with the limits for a Class B digital device, pursuant to
Part 15 of the FCC Rules. These limits are designed to provide reasonable protection against harmful
interference in a residential installation. This equipment generates, uses, and can radiate radio frequency
energy and, if not installed and used in accordance with the instructions, may cause harmful interference to
radio communications. However, there is no guarantee that interference will not occur in a particular
installation. If this equipment does cause harmful interference to radio or television reception, which can be
determined by turning the equipment off and on, the user is encouraged to try to correct the interference by one
or more of the following measures:
• Reorient or relocate the receiving antenna.
• Increase the separation between the equipment and receiver.

• Connect the equipment into an outlet on a circuit different from that to which the receiver is connected.
• Consult the dealer or an experienced radio/TV technician for help.
FCC caution
This device complies with Part 15 of the FCC Rules. Operation is subject to the following two conditions: (1)
This device may not cause harmful interference, and (2) this device must accept any interference received,
including interference that may cause undesired operation.
RF radiation exposure and hazard statement
To ensure compliance with FCC RF exposure requirements, this device must be installed in a location such
that the antenna of the device will be greater than 20 cm (8 in.) away from all persons. Using higher gain
antennas and types of antennas not covered under the FCC certification of this product is not allowed.
Installers of the radio and end users of the product must adhere to the installation instructions provided in this
manual. This transmitter must not be co-located or operating in conjunction with any other antenna or
transmitter.
Non-modification statement
Use only the supplied internal antenna, or external antennas supplied by the manufacturer. Unauthorized
antennas, modifications, or attachments could damage the WLAN Access Point 2330A/2330B and violate
FCC regulations. Any changes or modifications not expressly approved by the party responsible for
compliance could void the user's authority to operate this equipment. Contact Nortel for a list of approved
2.4 GHz and 5.0 GHz external antennas.
This device must be operated with the CAT-5 Ethernet cable installed on each activated AP 2330A/2330B
Ethernet Port to ensure compliance with the Class B emissions standards. Failure to comply with this
installation requirement may cause the device to operate in excess of the allowable emissions limits.
Deployment statement
This product is certified for indoor deployment only. Outdoor operation is allowed by exception only.
Please follow the guidelines outlined in the Outdoor Operation Section in this guide.
Canadian IC statement
Operation is subject to the following two conditions in Canada:
1 this device may not cause interference, and
2 this device must accept any interference, including interference that may cause undesired operation of the
device
To prevent radio interference to the licensed service (i.e. co-channel Mobile Satellite systems) this device is
intended to be operated indoors and away from windows to provide maximum shielding. Equipment (or its
transmit antenna) that is installed outdoors is subject to licensing and not supported by the WLAN Access
Point 2330A/2330B. Because high power radars are allocated as primary users (meaning they have priority) in
the 5250-5350 MHz band, these radars could cause interference and/or damage to license exempt WLAN
devices.

Nortel WLAN 2300 Series Outdoor Solution Guide
Basic outdoor installation information
Signal path distance
In an environment without obstacles in the signal path, the maximum communication distance between
antennas depends primarily on the types of antennas, the operating frequency, the data rate and the free space
loss between them. Make sure your proposed mounting site provides adequate clearance around the
transmitting antenna to enable adequate signal propagation. The Nortel WLAN 2300 Series Outdoor Solution
supports data rates up to 54 Mbps.
Signal attenuation and loss in outdoor installations
“Appendix” on page 69
Antenna polarization
“Appendix” on page 69
Signal path clearance
A radio beam is intended to travel from one antenna to another in a direct path. Therefore, the path between the
antennas must be free of major obstacles. The effects of obstacles and terrain, both along and near the path,
have a significant bearing on the propagation of radio signals and can cause both interference and signal
degradation.
When choosing a site, consider the effects of the following common obstacles:
• Trees and large plants
A tree directly in the path can completely block the signal. With sufficient clearance above the trees there are
usually no secondary effects, but you should allow for future tree growth.
• Man-made obstacles
A large round container such as a gas storage reservoir or water tower that is partially in the path causes some
blocking. These obstacles may also reflect some energy, which can interfere with other receivers. Square or
rectangular objects in or near the path have rectangular surfaces that can block and diffract signals over and
around them.
• Earth surface
The earth surface also interferes with signals if the antenna is mounted too low. Mount the antenna just high
enough to allow adequate clearance from the ground. Placing the antenna too high makes it susceptible to
interference from other systems.
Physical site survey
Perform a visual inspection of the site to determine and document the physical characteristics of the site and to
ensure that all requirements are met for the proper installation and operation of the system.

NN47250-503 (323847-C Version 02.01)
Contact information and access permissions
Make sure the following general requirements are met before beginning the installation:
• Confirm customer-provided information, such as site contact names and telephone numbers.
• Examine the building (tenant) lease to verify or establish building roof or tower rights. If available, use
layout drawings to evaluate the feasibility of modifications or special permits that might be necessary.
• For a tower-mounted installation, find out if the owner, operator, or landlord requires a professional or
certified tower climber to do the work.
Physical site
Make sure the following physical site requirements are met before beginning the installation:
• Identify the roof area, wall, or tower for mounting the antenna. You must choose a site with a clear
line-of-sight from the transmitting antenna.
• Determine the access area, such as a stairway or a ladder.
• Identify existing equipment installations and assess the condition of proposed towers or mounting structures.
• Assess environmental conditions, such as temperature, ventilation, and humidity.
Warning! Install this device in such a manner as to maintain a minimum of 20
cm (7.9 inches) separation distance between the radiating element(s) and all
persons. This safety warning conforms with FCC radio frequency exposure limits.
Warning! Intentional radiators, such as the Nortel WLAN Access Points
2330A/2330B are not intended to be operated with any antenna(s) other than
those furnished by Nortel. An intentional radiator may only be operated with the
antenna(s) with which it is authorized. For a complete listing of the authorized
antennas for use with this product, visit http://www.nortel.com/support.
Caution! Do not install the outdoor antenna or connect it to the surge
suppressor/Access Point during a storm.

Figure 2. Outdoor External Antenna Supported Connection Configurations
Outdoor external antenna connection scenarios
There are three basic connection scenarios that are supported for implementing the Nortel WLAN 2300 Series
Outdoor Solution. These are described in the following table:
46 WLAN 2300 Series Outdoor Solution with Indoor Mounted AP
NN47250-503 (323847-C Version 02.01)
Based on these three scenarios, the following tables illustrate the additional amount of power loss that will be
realized when the extra cables and components are used to enable the access point to be mounted indoors and
the radiating element (i.e. antenna) to be mounted on the exterior of the premises. These additional losses need
to be factored into the overall system path loss equation when selecting placement of the access points and net
coverage areas. The current implementation of the WSS and WMS software does not allow for optimization of
performance by increasing the transmitter's output power to compensate for the added loss. That feature will
be available in a subsequent release of the WSS and WMS software. The values listed in the following tables
can be used to estimate a net reduction in total system power and coverage area.
For reference, a 3 dB reduction in power equates to halving the effective linear power. This translates to a
reduction in available range of a factor of four times. An additional loss of 3 dB would halve the power again
and reduce the range by another factor of four times. Hence, care should be taken to place the access point as
near to the point of debarkation from the premises as possible to reduce signal loss and optimize the outdoor
coverage area.

Surge suppressor (lightning arrestor)
The Nortel series gas-discharge surge suppressors (lightning arresters) provide high-level protection for
transmitters and receives at RF-communication sites. In the event of a local strike, the unit’s gas discharge tube
ionizes instantaneously to limit sudden voltage surges across the coaxial line. When connected to a satisfactory
ground, the unit can safely shunt up to 5000 Amps of impulse current away from sensitive station equipment.

Figure 3. Surge suppressor
Installation
For best results, install the surge suppressor in close proximity to a low-resistance ground at a point where the
coaxial cable enters the building. In most cases, one 8-foot rod driven into moist soil or multiple rods bonded
together will provide adequate grounding. (see National Electrical Code guidelines).
Install the surge suppressor in an accessible location that allows for periodic inspection and possible
replacement of the gas cartridge. Provide drip loops in the cables to prevent water from entering the building,
see (Figure 6 on page 50).
The life expectancy of the replaceable gas tube depends on the frequency and severity of electrostatic activity
at the site. Low-level conduction resulting from near-by storm activity has very little impact on the life of the
cartridge, but powerful surges induced by on-site strikes will eventually result in degraded performance or
failure. Degraded performance indicators include reduced receiver sensitivity, above normal VSWR readings,
and RF heating of the surge suppressor body during transmit mode. Should the discharge tube fail totally, it
becomes a permanently conductive protective shunt to ground. Periodic SWR checks provide a good indicator
of deteriorating performance, and routine replacement may be indicated following especially severe weather
events where multiple on-site strikes were known to have happened.
Warning! A properly rated surge suppressor is required for any
cable/antenna combination exiting the building. The required components must
be rated and approved for use in the intended application.
WLAN 2300 Series Outdoor Solution with Indoor Mounted AP 49
Nortel WLAN 2300 Series Outdoor Solution Guide
Figure 4. #8 Ground lead
Grounding principles
To connect the surge suppressor to ground, use the shortest and most direct run possible with #8 solid copper
wire (or equivalent). For exterior installations, weatherproof the coax connectors with a suitable mastic or
rubberized tape to prevent water infiltration. (see Figure 4 on page 49).
Warning! All wiring and cables to the Access Point, the surge suppressor and
the outdoor antenna should be routed separately. It is particularly important
that AC wiring or other outside cabling does not come in contact with the
Access Point, antenna cables or interface wiring.
Caution! The power source equipment connected to the Access Point, such as the
Wireless Security Switch or PoE injector, must be provided with a reliable earth ground to
insure safety of the system.

Access Points 2330A and AP 2330B. The portfolio includes 802.11b/g (2.4 GHz) and 802.11a (5.0 GHz)
models for outdoor use. The addition of outdoor external antennas to the WLAN 2300 Series System portfolio
improves overall system value:
• Improved deployment flexibility - Planners can choose an antenna pattern that meets coverage requirements
while allowing for convenient AP placement and installation.
• Improved coverage and performance - External antennas allow planners to optimize coverage and deliver
higher available data rates to user concentrations.
• Can provide a low cost fix for trouble spots - Appropriately outfitting existing APs with external antennas
can greatly improve coverage and available data rates in areas that are not adequately serviced.
• Lower cost of coverage - External antennas improve overall system efficiency by effectively directing
available energy to where it's needed. This ensures overall system utility is maximized for any installation.
The WLAN 2300 series outdoor external antennas are the only external antennas certified by Nortel for use
with WLAN 2300 Series systems. WLAN Access Points AP 2330A and AP 2330B that are outfitted with
non-certified outdoor external antennas are not supported under Nortel support agreements.
The WLAN 2300 Series system must be upgraded to WSS Software Release 5.0.11.4 or later and WMS
Software Release 5.0.11.3 or later. This upgrade includes antenna pattern libraries for the WLAN 2300 series
outdoor external antenna portfolio and allows the system to:
• Compensate for extension cable loss and lightning protection circuitry that is essential for operation in an
outdoor environment.
• Correctly interpret received signal strength measurements from APs with external antennas when calculating
rogue device or client location.
The WLAN 2300 Series System outdoor external antenna portfolio is sourced from Cushcraft, a world leader
in the development of advanced antenna technology and products.
• The Cushcraft products have been modified for compatibility with the AP Access Points 2330A and AP
2330B.

Coax cable seal installation
Applying coax seal tape
You must weather seal all outside coaxial connections using the coax seal tape provided in the mounting kit.
Coax connections that are not properly sealed permit moisture to enter the connection, which leads to
performance degradation or link problems.
To apply the coax seal tape, follow these steps:
1 Make sure that the coaxial cables, connectors, and the connector area are clean and dry.
2 Peel the paper backing from a length of coax seal tape.
3 Wrap each connector with the coax seal tape, starting at the coaxial cable, extending across the connector
body, and finishing close the lightning arrestor surge suppressor or grounding block. Overlap each turn at
least 50 percent so there is a double thickness over all areas. See Figure 7 on page 52.
Figure 7. Applying the coax seal tape before smoothing.
Use your fingers to mold and form the coax seal tape around the cable and connector to form a smooth, neat
surface. Be sure to squeeze out any air pockets. See Figure 8 on page 53
Note. Do not use plastic or vinyl electrical tape on the connectors because it will
deteriorate during long-term exposure to ultraviolet light and extreme weather.

Figure 8. Coax seal tape after smoothing.
4 Visually inspect the seal to make sure the entire connector area is completely covered. If you find gaps,
apply additional Coax-Seal over the existing material and then mold it to shape
5 Repeat these steps for each coaxial connection outside.
Physical site survey
Perform a visual inspection to determine and document the physical characteristics of the site and to ensure
that all requirements are met for the proper installation and operation of the system.
Physical site
Make sure the following requirements for your physical site are met before beginning the installation:
• Identify the roof area, wall, or tower for mounting the solution. You must choose a site with a clear
line-of-sight from the transmitting antenna.
• Determine the access area, such as a stairway or a ladder.
• Identify existing equipment installations and assess the condition of proposed towers or mounting structures.
Assess environmental conditions, such as temperature, ventilation, and humidity.
Cable routes
Make sure the following cable route requirements are met before beginning the installation:
• Determine cable routes, building entry points, and any special routing or support requirements (conduits,
bracing, cable trays, safety structures, and so on). Make sure the total cable length between the access point
and the wireless security switch is no greater than 100 meters.
• Identify necessary floor, roof, or wall penetrations and specify the locations.
• Document existing grounding system and connection requirements for new equipment.
• Refer to these electrical codes for your local regulations:
NFPA 70 (US National Electrical Code)
Canadian Electrical Code, Part1, CSA 22.1
IEC 364, Part 1 through 7 for other countries

NN47250-503 (323847-C Version 02.01)
Software installation
Country of operation
Before you can configure APs and radio parameters, you must specify the country in which you plan to operate
the radios. Since each country has different regulatory environments, the country code determines the transmit
power levels and channels you can configure on the radios. WSS software ensures that the values you can
configure are valid for the country you specify.
You must specify the country in which you plan to operate the WSS and its APs. WSS software does not allow
you to configure or enable the AP radios until you specify the country of operation
The country code is one of the parameters you set when you create a network plan. Be sure to select the
country code for the country in which the AP will be operated. It is a violation of regulatory laws to set the
country code to a country that is different than the actual country in which the AP is operating.
For a complete listing of the two-letter country codes, refer to the "Approved Countries for the WLAN 2300
Series Components" at http://www.nortel.com/support.

Safety Precautions
In this section Powerline and Installation safety precautions are provided.
Powerline
• Coming in contact with power lines can be lethal.
• Ensure that there are no accessible power lines near the installation site to avoid accidental or incidental
human contact with these lines.
• Ensure that antennas, masts, towers, guy wires or cables cannot come into contact with these powerlines. Try
to plan for potential leaning or falling of this equipment into these lines.
• You may get injured or killed if you are touching or holding any part of equipment when it contacts electric
power lines.
• Ensure there is NO possibility that equipment or personnel can come in contact directly or indirectly with
power lines.
60 WLAN 2300 Series Outdoor Solution with AP Mounted in NEMA Enclosure
NN47250-503 (323847-C Version 02.01)
• If anything, such as a wire or mast, does come in contact with a powerline, DO NOT TOUCH IT OR
ATTEMPT TO MOVE IT. Call the power company.
• Do not attempt to errect antennas or towers on windy days.
Installation
• The horizontal distance from a tower, mast or antenna to the nearest power line should be at least twice the
total length of the mast/antenna combination. This will ensure that the mast will not contact the power line if
it falls either during installation or later.
• Make sure that all towers and masts are securely grounded and electric cables connected to antennas have
lightning protection. This will help to prevent fire damage or human injury in case of lightning, static
build-up, or short circuit when equipment is connected to the antenna.
Heat /Cold loading
The NEMA Enclosure environment must not exceed the operating specifications for the AP (2330 A or
2330B). Temperature must be between 0 to 50 degrees C and humidity between 10 to 95%, non condensing.
Reference Information
The following section describes the Ethernet Lightning Surge Protector, Terminal Strip Connection, Coax
cable seal Installation, and Antennas.
Ethernet and Antenna Lightning Surge Protector
The Nortel series gas-discharge Antenna surge Protector (lightning protector) provides high-level protection
for transmitters and receivers at RF-communication sites. In the event of a local strike, the unit’s gas discharge
tube ionizes instananeously to limit sudden voltage surges across the coaxial line. When connected to a
satisfactory ground, the unit can safely shunt up to 5000 Amps of impulse current away from sensitive station
equipment.
Warning! A rated surge Protector is required for any cable/antenna combination exiting the
building. The required components must be rated and approved for use in the intended
application.
Installation
The Ethernet Lightning Surge Protector is mounted close to the building entrance. The cables must enter the
building through customer provided access, possibly through the drilled hole where there are communications
pipes.
For better results, install the Lightning Surge Protector in close proximity to a low-resistance ground at a point
where the Ethernet cable enters the building. In most cases, one 8-foot rod driven into moist soil or multiple
rods bonded together will provide adequate grounding.
Install the Lightning Surge Protector in an accessible location that allows for periodic inspection. Provide drip
loops in the cables to prevent water from entering the building.
WLAN 2300 Series Outdoor Solution with AP Mounted in NEMA Enclosure 61
Nortel WLAN 2300 Series Outdoor Solution Guide
Grounding principles
To connect the Surge Protector to ground, use the shortest and most direct run possible with #8 solid copper
wire (or equivalent).
Refer to your local electric code standards for correct installation.

Antenna properties and considerations
In the design and installation of a WLAN system, system installers need to have some fundamental knowledge
of antenna performance and RF propagation characteristics to ensure efficient performance of the network.
This knowledge will assist these individuals with the proper selection of system antennas, as well as, guiding
their decisions on antenna mounting location and orientation in an effort to ensure optimum system coverage
and performance. A properly selected antenna system has the capability of improving overall system
performance and may lead to a reduction in system cost if the overall number of access points can be reduced.
Conversely, a poorly selected antenna system may degrade system performance and may lead to an increase in
overall system cost.
Antenna properties
The external antennas supported by the Nortel WLAN 2300 system are passive devices. A key attribute
included in their design is that they are DC-coupled to the output of the WLAN access point to enable the
software to detect their presence and direct the energy out their aperture rather than through the internal
antennas mounted within the access point housing. Since they are passive devices, they do not process nor
amplify the RF signal. Even if they are 100% efficient, they cannot radiate more total power than is delivered
to their input terminal from the access point.
The basic properties that are used to describe the performance of an antenna include impedance and VSWR
(Voltage Standing Wave Ratio), radiation patterns, 3-dB beamwidth, directivity, gain, EIRP (Effective
Isotropic Radiated Power), polarization and bandwidth. These properties and their impact on system
performance are discussed in the following sections.
Impedance and VSWR
In order to achieve maximum power transfer between an access point and an antenna, the input impedance of
the antenna must identically match the characteristic impedance of the output of the access point. If the two
impedances do not match, a reflected wave will be created at the antenna input and travel back towards the
access point. This reflection is associated with a mismatch loss between the access point and the antenna and
results in an overall reduction of system efficiency and available transmission power. The WLAN supported
external antennas have been designed to match the output impedance of the WLAN 2300 series access points
to ensure optimum system power transfer.
The Voltage Standing Wave Ratio or VSWR is the ratio between the maximum voltage and the minimum
voltage that appears along the transmission line connecting the access point to the antenna. The VSWR, which
can be derived from the level of reflected and forward waves, is also an indication of how closely or efficiently
an antenna's input impedance is matched to the characteristic impedance of the cabling and output impedance
of the access point. An increase in VSWR indicates an increase in the mismatch between the antenna and the
access point. These increases can be a direct result of corrosion, damaged cables, loose connections or seals
and lengthy cable extensions from the access point. All of these concerns must be checked and optimized
during the installation of the antenna system by the professional installer.
To indicate how increased VSWR impacts overall system performance, the table below details the percentage
of power reflected by the antenna, and the resultant overall transmission loss, for several typical VSWR values.
For a 1.5:1 VSWR, the transmission loss is approximately 0.2 dB or a 4.0% reduction in efficiency.
78 Appendix
NN47250-503 (323847-C Version 02.01)
Radiation Patterns and 3-dB Beamwidth
The radiation patterns of an antenna describe how the antenna directs the energy it radiates. As stated earlier,
an antenna cannot radiate more total energy than is delivered to its input. All antennas, if 100% efficient, will
radiate the same total energy for equal input power, regardless of the shape of the radiating pattern.
In many cases, the convention of an E-plane and H-plane pattern is used in the presentation of antenna pattern
data. The E-plane is the plane that contains the antenna's radiated electric field potential while the H-plane is
the plane that contains the antenna's radiated magnetic field potential. These planes are always orthogonal. For
dipole and Yagi antennas, the E-plane is always in the plane parallel to the linear antenna elements.
The information obtained from these plots includes the 3-dB beamwidth. The 3-dB beamwidth of an antenna
is a measure of the angular width or spread of the signal at the points on the radiating signal where the power
has been reduced to 1/2 of its original power level.
Additional factors that affect the antenna's efficiency are the antenna side lobe level and front to back ratio.
These parameters are measures of how much energy the antenna radiates outside of its main beam. The side
lobe level describes the relative level of minor pattern lobes outside the main beam while the front to back ratio
describes the level of radiation directly opposite (180 degrees away) from the main beam. Ideally, these levels
should be as low as possible since they reduce the directivity and efficiency of the main beam. When
transmitting, the presence of side and back lobes may cause interference to other nearby access points, and
when receiving, they may allow interference into the access point from surrounding WLANs or rogue devices.
Directivity and Gain
The directivity of an antenna is a relative measure of how an antenna focuses or directs the energy it radiates in
the main beam of the antenna pattern. It is defined as the ratio of the antenna radiation intensity in a specific
direction to the radiation intensity of an isotropic radiator for the same radiated power. The higher the
directivity, the more focused the antenna pattern.
The gain of an antenna is closely related to its directivity, but takes into consideration the losses in the antenna,
such as conduction and dielectric losses, as well as, the directional capabilities of the antenna. By definition, it
is equal to 4 times the ratio of the maximum radiation intensity to the net power accepted by the antenna at its
input.
Gain is measured on a far-field outdoor test range by comparing the gain of the antenna under test to that of a
pre-calibrated Standard Gain antenna:
Table 15: VSWR, % Reflected Power and Transmission Loss

1.0 : 1 0.00 0.00
1.1 : 1 0.23 0.01
1.2 : 1 0.83 0.04
1.5 : 1 4.00 0.18
2.0 : 1 11.11 0.51
2.5 : 1 18.37 0.88
3.0 : 1 25.00 1.25
Appendix 79
Nortel WLAN 2300 Series Outdoor Solution Guide
If we double the length of the aperture, the gain of the antenna is doubled, which means the gain increases by
3 dB.
An antenna's efficiency is a measure of the ratio of the gain of an antenna to its directivity. If an antenna were
100% efficient, it would have a gain equal to its directivity. The VSWR provides an indication of how closely
the impedance of an antenna matches the impedance of the connecting access point. If an impedance mismatch
exists, a reflected wave will be created and will reduce the level of forward energy transferred from the access
point into the antenna. This effectively reduces the total level of radiated energy and the effective gain of the
antenna.
Effective Radiated Power
Effective Isotropic Radiated Power (EIRP) is a figure of merit for the net radiated power in a given direction. It
is equal to the product of the power supplied to an antenna and the antenna gain in a given direction relative to
an isotropic radiator. It can be expressed in watts or dBm.
Polarization
The polarization of an antenna describes the orientation and sense of the radiated wave's electric field vector.
All radiated waves are defined as elliptically polarized. In this general case, the antenna's total electric field
(E-field) has two components that lie in the same plane. These two E-field components may be of different
strength and are oriented at different angles.
The most common cases of elliptical polarization are:
Circular, in which the two E-field components are equal in magnitude, 90 degrees out of phase and spatially
oriented at 90 degrees from one another, and
Linear, in which the wave has a single E-field component. In a linear polarized antenna, the E-field is either in
a vertical line, a horizontal line or a slanted line, such as 45 degrees from the horizontal.
The term axial ratio is used to define the relative strength of the two E-field components in an elliptically
polarized wave. For pure circular polarization the axial ratio is 0 dB and for linear polarization the axial ratio is
infinite.
The important performance issue relative to signal polarization is that maximum energy transfer between a
transmitting antenna and a receiving antenna will only occur if both antennas have identical axial ratio,
identical polarization sense and the same spatial orientation. It is assumed that nothing in the propagation path
causes the signal polarization to change, which is known as polarization distortion.
80 Appendix
NN47250-503 (323847-C Version 02.01)
With linearly polarized antennas, the polarization of each antenna must be of the same orientation to achieve
maximum energy transfer between the two antennas. If the two linearly polarized antennas are not identically
oriented, there will be a reduction in energy transfer due to polarization mismatch. The table below provides a
summary of polarization mismatch loss between two linearly polarized antennas that do not have the same
angular orientation.
The following table provides a summary of the polarization mismatch between a linearly polarized and a
circularly polarized wave as a function of the circularly polarized wave's axial ratio. It is assumed that the
circularly polarized wave's field components are orthogonal.

Bandwidth
The term bandwidth simply defines the frequency range over which an antenna meets a certain set of
performance criteria. The important issue to consider regarding bandwidth is the performance tradeoffs
between all of the properties described above as the bandwidth is widened to cover more area.
Summary of Related Performance Tradeoff Issues
The antenna properties described above are all related in varying degrees. In selecting or designing an antenna
system, the tradeoffs between all of these performance properties must be considered in order to ensure
optimum system performance. These factors must also be weighed against factors beyond the actual antenna
properties such as RF propagation and path loss.
In all cases, the required or specified performance properties of an antenna can only be achieved over a limited
frequency bandwidth. The extent of this realizable bandwidth is a function of the performance requirements,
antenna type selected and the antenna size relative to the operating wavelength. Typically, optimum antenna
performance is achieved at the center frequency of the operating band.
In the case of VSWR, system performance is typically degraded at the edges of the operating frequency band.
The overall effect on system performance is a decrease in antenna gain due to impedance mismatch losses. The
antenna's radiation patterns, beamwidth, directivity (gain) and bandwidth are more directly related. As with
VSWR, performance is usually degraded at the edges of the operating band.
The 3-dB beamwidth and directivity (gain) are inversely proportional. As the antenna beamwidth decreases,
the directivity increases. These parameters are also related to the antenna size or aperture. As the antenna
aperture or size increases with respect to the operating wavelength, the radiation beamwidth decreases.
Therefore, to achieve increased antenna gain, it is required that the antenna size increase.
For linearly polarized antennas, polarization is generally not a function of bandwidth. However, this is not
always the case for circularly polarized antennas. In most cases, the polarization axial ratio for a circularly
polarized antenna increases at the edges of the operating frequency band.
RF Propagation and Path Loss
In addition to the antenna properties and wireless system hardware, other factors can influence the overall
performance of the WLAN system. These factors affect the propagation of RF signals through the air medium
and need to be considered when architecting a WLAN.
Path loss is encountered when an RF signal propagates through the air. The relative signal strength of the
propagating wave diminishes as a function of distance traveled from the transmitting antenna.
The free space propagation loss factor is described by the following equation,
82 Appendix
NN47250-503 (323847-C Version 02.01)
To minimize path loss effects, you can either increase the transmit power, increases the system gain, decrease
the operating frequency or increase the receiver sensitivity on the other end of the wireless communications
link. In addition, path loss increases by a factor of approximately 6 dB for every doubling of frequency or path
distance. This factor is significant because it means that a doubling of the antenna or system gain, an increase
of 3 dB, will not double the propagation distance of the signal. To double the usable coverage area or path
distance, the antenna or system gain would have to increase by a factor of four, which equates to an increase of
6 dB.

In addition to the free space path loss mentioned above, RF signals will be attenuated as they pass through
objects such as foliage, walls and buildings. The level of signal attenuation in these instances can increase the
loss and reduce the communications range by an additional amount of 10 to 20 dB or greater. Care should be
used when installing the antennas and access points to ensure that no objects or barriers are blocking the
communication paths of the antennas.
Most, if not all, antenna performance characteristics are specified under free space conditions. It is important
to realize that these performance characteristics may change once the antenna is located in its operating
environment. Surrounding objects, such as the earth, walls, buildings, floors, etc. will impact the antenna's
specified performance. The fact that antenna performance may change in the operating environment does not
invalidate the use of free space data. It is impossible to specify performance for all environments and the free
space performance characteristics provide the most suitable reference for comparing relative antenna
performance.
When an antenna is located near the earth, its radiated field couples with the earth and changes the antenna's
radiation pattern and impedance characteristics. The antenna impedance is changed from its free space value
by the addition of a component known as ground impedance. The presence of this component changes how RF
energy is delivered to the antenna in that some energy normally radiated by the antenna is now dissipated in the
earth. This will reduce the system efficiency.
In addition to impacting the antenna impedance, the earth also changes the antenna's radiation pattern and
polarization depending upon the height the antenna is located above the ground. When an antenna is located
over the earth, an "image" is generated in the earth. This image will contribute to the total radiated field by
vector summing the direct and reflected waves. This is essentially a multipath phenomenon and illustrates how
the antenna height affects pattern performance. Mechanical down-tilt can be used to try and compensate for
these effects. Down-tilt refers to tilting the main beam downward, away from the perpendicular with the
horizon. Mechanical down-tilt really only applies to sectorized antennas that have narrow horizontal
beamwidths of less than or equal to 60 degrees. The narrower the azimuth pattern, the more uniform the tilt
will be across the 3-dB beamwidth of the antenna.
Optimizing antenna location can reduce multipath and interference problems. This includes antenna height, as
well as, location relative to nearby objects. Protecting against multipath fading is difficult and may require
other techniques, such as diversity, to mitigate multipath interference. Overall antenna selection and location
optimization is not an arbitrary task. It does require an evaluation of system coverage and range requirements,
a review of access point locations, and a review of surrounding objects that may become a source of
interference.
