5.2 FREQUENCYBANDRANGES
In the 2.4-, 5.2-, 5.1-, 5.4-, and 5.7-GHz frequency band ranges, Cyclone APs, SMs, and
BHs are available. Additionally, in the 900-MHz frequency band range, Cyclone APs and
SMs are available. National restrictions may apply. See Regulatory and Legal Notices on
Page
493.
To avoid self-interference, a Cyclone network typically uses two or more of these ranges.
For example, where properly arranged, all AP clusters and their respective SMs can use
the 2.4-GHz range where the BH links use the 5.7-GHz range. In this scenario,
subscriber links can span as far as 5 miles (8 km) with no reflector dishes, and the BH
links can span as far as 35 miles (56 km) with reflector dishes on both ends.
Within this example network, wherever the 2.4-GHz module is susceptible to interference
from other sources, AP clusters and their linked SMs may use the 5.2-GHz range to span
as far as 2 miles (3.2 km) with no reflector dishes. The network in this example takes
advantage of frequency band range-specific characteristics of Cyclone modules as
follows:
• The 900-MHz modules cover a larger area, albeit with lower throughput, than
modules of the other frequency bands. The 900-MHz modules can be used to
• penetrate foliage
• establish links that span greater distances
• add subscribers
• add overall throughput where modules of other frequency bands cannot be
used (such as where interference would result or space on a tower is
limited).
• The 2.4-GHz frequency band range supports AP/SM links of greater than 2-mile
spans (with no reflectors).
• The 5.7-GHz frequency band range supports BH links that span as far as 35
miles.
