Integrated Antennas Review: Standard SMs and APs have an integrated 60 degree sector antenna. 6 APs make a cluster Motorola offers “connectorized” (external antenna connector) versions (900MHz, 4.9GHz) Several aftermarket companies produce an AP with an external Omni Motorola Reflector can be used at the SM to get more distance

Canopy Antennas One of the most important performance issue for antenna handles interference is its “Front- to-Back” ratio. F-to-B indicates how much of an incoming signal will be absorbed coming into the front as compared to the back. This is VERY important in cellular networks Canopy has a Front-to-Back of 20dB A canopy AP can be hit with a signal as high as -60dB and still support connections on APs
