Overview
To optimize the overall performance of a Xirrus WLAN in an outdoor deployment it is important to understand how to maximize coverage with the appropriate antenna selection and placement. This document is meant to serve as a guideline for anyone who wishes to use Xirrus’ antennas and related accessories with Xirrus’ outdoor wireless products (XR-520H, XR-2425H, and XH2-120). The document is organized according to the following sub-sections:
• Basic Technical Background
• Types of available Xirrus Antennas and Accessories
• Design Considerations and Reference Use Cases
Technical Background
ISM bands:
The U.S. Federal Communications Commission (FCC) authorizes commercial
wireless network products to operate in the Industrial, Scientic and Medical (ISM) bands using spread spectrum modulation. The ISM bands are located at three different frequencies ranges – 900MHz, 2.4GHz and 5GHz. This document covers products that operate in the 2.4 and 5GHz bands.
ISM bands allow manufacturers and users to operate wireless products in the U.S. without requiring specic licenses. This requirement may vary in other
countries. The products themselves must meet certain requirements in order
to be certied for sale such as maximum Transmit Power (Tx Power) and Effective Isotropic Radiated Power (EIRP) ratings.
Each of the ISM bands has different characteristics. The lower frequency bands
exhibit better range but with limited bandwidth and hence lower data rates. Higher frequency bands have less range and are subject to greater attenuation from solid objects.
Antenna Properties, Ratings and Representation
At the most fundamental level an Antenna provides a wireless communication system three main attributes that are inter-related to each other and
ultimately inuence the overall radiation pattern produced by the antenna:
• Gain
• Directivity
• Polarization
Gain of an Antenna is a measure of the increase in power that the antenna
provides. Antenna gain is measured in decibels (dB) — a logarithmic unit used to express the ratio between two values of a given physical quantity. In the general case, the gain in dB is a factor of the ratio of output power (or radiated power) to the input power of the antenna (that ratio is also called the
“efciency” of the antenna). In practice, the gain of a given antenna is
commonly expressed by comparing it to the gain of an isotropic antenna. An
isotropic antenna is a “theoretical antenna” with a perfectly uniform
three-dimensional radiation pattern. When expressed relative to an isotropic antenna, the gain of a given antenna is represented in dBi (i for isotropic). By that measure, a truly isotropic antenna would have a power rating of 0 dB. The U.S. FCC uses dBi in its calculations.
Directivity is the factor that was referred to in the previous discussion about
antenna gain and its relation to efciency. Mathematically, the gain of an antenna is its directivity times its efciency. And like its gain, the directivity of a
given antenna is also expressed relative to an isotropic antenna. The directivity measures the power density that an antenna radiates in the direction of its strongest emission, relative to the power density radiated by an ideal isotropic antenna (which emits uniformly in all directions), when they are both radiating the same total power.
Polarization of an antenna is the orientation of the electric eld of the radio
wave that it produces relative to the earth’s surface. The polarization of an antenna is determined by the physical structure of the antenna and by its
Xirrus External Antennas Guide
Page 3
orientation. A simple straight wire antenna will have one polarization when mounted vertically and a different polarization when mounted horizontally. A linear polarized antenna radiates wholly in one plain containing the direction of propagation of the radio wave while, in a circular polarized antenna, the plane of polarization rotates in a circle making one complete revolution during one period of the wave. A linear polarized
antenna may be either Horizontally Polarized (if the direction of propagation is parallel to the earth’s surface) or Vertically Polarized (if the
direction of propagation is perpendicular to the earth’s surface). A circular polarized antenna may be either Right-Hand-Circular (RHC) or Left-Hand-Circular (LHC) depending on whether the direction of rotation of the plane of propagation is clockwise
or counterclockwise respectively. Polarization is an important design consideration, particularly in Line of Sight (LOS) or Point-to-Point type
deployments because maximum signal strength between sending and receiving antennas occurs when both are using identical polarization.
Radiation Pattern of an antenna is a plot of the relative strength of the
electromagnetic eld of the radio waves emitted by the antenna at
different angles. The radiation pattern of the theoretical isotropic antenna, which radiates equally in all directions, would look like a sphere.
Impedance Matching is an important consideration in the design of the
overall wireless communication system. At each interface, depending on the impedance mismatch, some fraction of the propagating radio wave’s
energy will reect back into the source. This reecting wave is called a
standing wave and the ratio of maximum power to minimum power in the standing wave is called the Voltage Standing Wave Ratio (VSWR). A VSWR of 1:1 is ideal.
Types of Xirrus Antennas
The tables starting on the next page detail the specications of the different antennas Xirrus offers for use with its Access Points, in both
2.4GHz and 5GHz. Each type of antenna will offer certain coverage capabilities suited for specic applications (as discussed in the later section
of this document). As a general rule of thumb as the gain of an antenna increases, there is some tradeoff to its coverage area. High gain antennas will typically offer longer coverage distance but smaller (and more directed) coverage area.
* Each antenna can be connected simultaneously to 2 radios on different bands (2.4GHz and 5GHz) with additional cables. Additional antennas and cables
are required to connect multiple radios on the same band.

Design Considerations and Reference Use Cases
There are several factors that impact the performance of a Wireless LAN and must be kept in mind while designing for a deployment. Some of the key considerations are as follows:
Mobility of the Application: The mobility of the clients that will be
connecting to the Array through the antenna system is the rst
thing to think about when planning a deployment. An application that has a lot of mobile users, such as a convention center is best served by a large number of omnidirectional microcells while a point-to-point application, which connects two or more stationary users may be best served by a directional antenna.
Physical Environment: Some of the things to watch for in the
environment where the WLAN deployment is planned include:
• Building construction – The density of the materials used in a building’s construction determines the number of walls the RF signal can pass through and still maintain adequate coverage. The following is a good reference but the actual effect of the walls on RF must be tested through a site survey. A thick metal
wall, such as an elevator reects signals, resulting in poor
penetration of the signal and low quality of reception on the
other side. Solid walls and oors and precast concrete walls can
limit signal penetration to one or two walls without degrading coverage, but, this can vary greatly depending on the amount of steel reinforcing within the concrete. Concrete and concrete block walls will likely limit signal penetration to three or four walls. Wood or dry wall will typically allow for adequate signal
penetration through ve or six walls. Paper and Vinyl walls have
little effect on signal penetration.
• Ceiling height
• Internal obstructions – Product inventory and racking are factors
to consider in a indoor environment, such as a warehouse. In outdoor environments, many objects can affect antenna patterns, including trees, vehicles and buildings.
• Available mounting locations.
In addition, consideration some consideration should also be given to aesthetic appearance.
Access to network connections (minimize Antenna cable runs):
Cabling between the Array or AP and the antenna introduces
losses in the system, therefore the length of this cable run must be minimized as much as possible.
Warehouse Use Case: In most cases, these installations require
a large coverage area. Experience has shown that multiple
omnidirectional antennas (such as ANT-OMNI-1x1-01 or ANTOMNI-2x2-02) mounted at 20 or 25 feet typically provide the
best coverage. Of course this is also affected by the height of the racking, the material in the racks and your ability to locate the antenna at this height. The antenna should be placed in the center of the desired coverage cell an in an open area for best performance. In cases where the ceiling is too high and the Array
or AP will be located against a wall, a directional antenna may
be used.
Small Ofce or Small Retail Store: An omnidirectional dipole
antenna (such as ANT-OMNI-1x1-01 or ANT-OMNI-2x2-02) will
provide best coverage for type of scenario.
Enterprise or Large Retail Store: In most such deployments, there
is a need for a fairly large coverage area and a combination of omnidirectional and directional antennas must be used. Omnidirectional antennas located just below the ceiling girders or just below the drop ceiling and directional antennas located at the corners. Also, for areas that are long and narrow – such as long store aisles – a directional antenna at one end may provide better coverage. Keep in mind that the radiation angle of the antenna will also affect the coverage area.
Apartment Complex Backhaul (Point-to-Point): For an application
where last mile connectivity is being provided using Wi-Fi (such as apartment complexes or senior living complexes that may not have traditional wiring infrastructure), point-to-point connections are common. When establishing point to point connections in outdoor environments, the distance, obstructions
Page 14
and antenna locations must be considered. For short distances (several hundred feet), a standard dipole antenna may be used. For very large distances (1/2 mile or more) high-gain directional antennas must be used. The antennas must be installed as high as possible, above obstructions such as trees, buildings and similar. If directional antennas are used, they must be aligned so that their main radiated power lobes are directed at each other.
