5.1.7 900‐MHzAPandSM
Cyclone 900 MHz AP and SM modules operate at a 3.3 Mbps carrier rate (compared to
10 Mbps for other Cyclone frequency bands).
Figure 6: Examples of flat panel antennas with 900-MHz modules
These 900-MHz modules run the same software and provide the same parameters,
network features, and connections as all other Cyclone APs and SMs. The physics of
longer-wavelength 900 MHz, the power allowed by regulatory authorities, and the low
required level of Cyclone Carrier-to-Interference (C/I) ratio combine to support
◦ line of sight (LOS) range of up to 40 miles (over 64 km)
◦ increased non-line of sight (NLOS) range, depending on RF considerations such
as foliage, topography, and obstructions.
When collocated with a Canopy SM of another frequency band range, the 900-MHz AP
may serve, without a tower or BH, as a remote AP (see
Deploying a Remote AP on
Page
148). 900-MHz AP/SM links are logical choices for extending radio networks where
you wish to
• add subscriber-handling capacity to a tower that is either
• fully used in the other frequency band ranges.
• not available to any other frequency band range.
• reach sparsely populated areas.
• penetrate foliage.
• add a remote AP behind an SM that operates in another frequency band range.
