Module Housing
The HSG-01 Plastic Housing is available for replacement of a
damaged housing on a module that is otherwise functional. The
HSG-01 is pictured in Figure 23.
The HSG-01 and all module housings of this design provide
clearances for cable ties on the Ethernet and sync cables.
RECOMMENDATION:
Use 0.14” (40-lb tensile strength) cable ties
to secure the Ethernet and sync cables to
the cable guides on the module housing.
For the Ethernet cable tie, the Ethernet cable groove is molded
lower at the top edge. For the sync cable tie, removal of a
breakaway plug provides clearance for the sync cable, and
removal of two breakaway side plates provides clearance for the
sync cable tie.

NOTE:
No replacement housing is available for an OFDM radio.
Frequency Band Ranges
In the 2.4-, 5.2-, 5.4-, and 5.7-GHz frequency band ranges, APs, SMs, and wireless Ethernet
bridges are available. APs and SMs are also available in the 900-MHz frequency band range.
National restrictions may apply. See Regulatory and Legal Notices on Page 583.
To avoid self-interference, a 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 or 16 miles (25 km) in 1X operation with LENS 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 modules as follows:
