Cisco Aironet Antennas and Accessories

Every wireless Local Area Network (LAN) deployment is different. When engineering an in-building solution, varying facility sizes, construction materials, and interior divisions raise a host of transmission and multipath considerations. When implementing a building-to-building solution, distance, physical obstructions between facilities, and number of transmission points must be taken into account. Cisco is committed to providing not only the best access points, client adapters, and bridges in the industry—it is also committed to providing a complete solution for any wireless LAN deployment. That's why Cisco has the widest range of antennas, cable, and accessories available from any wireless manufacturer. Figure 1 Cisco offers a complete range of 2.4 GHz antennas for client adapter, access point, and bridge equipment that enable a customized wireless solution for almost any installation. With the Cisco FCC-approved directional1 and omnidirectional2 antennas, low-loss cable, mounting hardware, and other accessories, installers can customize a wireless solution that meets the requirements of even the most challenging applications. Client Adapter Antenna Cisco Aironet wireless client adapters come complete with standard antennas that provide sufficient range3 for most applications at 11 Mbps. To extend the transmission range for a more specialized application when using the LMC adapter, a higher-gain4 antenna is offered. (See Table 1.) Table 1 Cisco Aironet Client Antenna Features

(261 g) 1 A type of low-gain (2.2 dBi) antenna consisting of two (often internal) elements. 2 An intelligent system of two antennas that continually senses incoming radio signals and automatically selects the antenna best positioned to receive it. 3 A ratio of decibels to an isotropic antenna that is commonly used to measure antenna gain. The greater the dBi value, the higher the gain and, as such, the more acute the angle of coverage. 4 All range estimations are based on an integrated client adapter antenna associating with an access point under ideal indoor conditions. The distances referenced here are approximations and should be used for estimation purposes only. Access Point Antennas Cisco Aironet access point antennas are compatible with all Cisco RP-TNC-equipped access points. The antennas are available with different gain and range capabilities, beam widths5, and form factors. Coupling the right antenna with the right access point allows for efficient coverage in any facility, as well as better reliability at higher data rates. (See Table 2.)

Low Loss/Ultra Low Loss Cables Low-loss cable extends the length between any Cisco Aironet bridge and the antenna.With a loss of 6.7 dB per 100 feet (30m) for the low-loss cable and 4.4 dB for the ultra low-loss cable, this provides installation flexibility without a significant sacrifice in range.

Directional antenna types include yagi, patch, and parabolic dish antennas. A yagi is a type of cylindrical directional antenna. A patch antenna is a type of flat antenna

is a concave or dish-shaped object. Often refers to dish antennas. Parabolic dish antennas tend to provide the greatest gain and the narrowest beam width making them ideal for point-to-point transmission over the longest distances. 2 An antenna that provides a 360-degree transmission pattern. These types of antennas are used when coverage in all directions is required. 3 A linear measure of the distance that a transmitter can send a signal. 4 A method of increasing the transmission distance of a radio by the concentration of its signal in a single direction, typically through the use of a directional antenna. Gain does not increase the signal strength of a radio, but simply redirects it. Therefore, as gain increases, the decrease in angle of coverage is inversely proportional 5 The angle of signal coverage provided by a radio; it may be decreased by a directional antenna to increase gain.
