Access Networks

Motorola wireless Access Points and Subscriber Modules comprise the access network. APs are the distribution head end and each one serves up to 200 subscribers. APs can be clustered in groups providing coverage for a community of subscribers. SMs are installed at the subscriber location. The new Canopy 400 and 500 Series AP and SM products provide near-line-of-sight (nLOS) and nonline- of-sight (NLOS) performance through the use of OFDM technology, longer cyclic prefixes, and higher gain antenna solutions. The improvement is seen most in multi-path environments where the signal is

reflected off other buildings and objects. Improvements in penetration of foliage are also possible. In general, OFDM technology improves performance in near- and non-line-of-sight environments. This

makes it possible to provide connectivity in areas where trees or other items may be present.
