Motorola Enterprise Wireless LAN Antennas

Using this guide
This guide has been designed to help you choose the right Motorola antenna and accessories for your wireless LAN deployment. It explains key factors to consider when choosing an antenna, and provides tables illustrating various key characteristics of each antenna. A compatibility chart is also provided to show which Motorola productsare compatible with each other and what accessories may be required to complete the system. A Motorola representative or sales partner can also help you determine the best configuration for your installation.

Antenna selection
While several antennas may work in a given environment, some will provide better coverage than others. Using the right antenna in the right locationwill maximize both the performance and coverage of your network. Understanding the key characteristics that describe how an antenna sends and receives radio frequency signals is critical to finding the ideal antenna. Motorola Enterprise Wireless LAN products operate in the 2.4 GHz and 5 GHz ISM bands allocated for unlicensed use. Access point and access port products available today supporteither the 802.11b/g or the 802.11a standard, or both. Wireless devices conforming to the 802.11b/g standard operate in the 2.4 GHz ISM band, while 802.11a devices operate in the 5 GHz band. The antennas in this guide are grouped according to the frequency band they support. Note that some antennas are designed to operate on either band. These antennas, described as “Dual-band” may be connected toradios operating in either the 2.4 or 5 GHz bands, although a single antenna may not be connected to two radios at the same time.

They usually have gain greater than 5 dBi and are not suitable for omni-directional situations. Ideally suited for long hallways. Patch: A flat antenna that is mounted on the ceiling but whose pattern is omni-directional. Most of the energy goes out horizontally to thesides of the antenna and equal in all directions. Dipole: A tubular antenna that can be either a pipe shape, a straight flexible rod or a paddle. This antenna has an omni-directional pattern when placed in a vertical position. It usually has 2 dBi of gain. Dipole Array: Essentially a dipole, a dipole array is two or more dipoles that are placed one on top of the other, requiring a longer tube to...
