Where the SM simply serves as a relay, you must use a straight-through RJ-45
female-to-female coupler, and wire the SM to the remote AP as shown in Figure 47.

Accounting for Link Ranges and Data Handling
Requirements
For aggregate throughput correlation to link distance in both point-to-multipoint and
point-to-point links, see

• all regulations that apply in your region and nation(s).
Avoiding Self Interference
For 5.2-, 5.4-, and 5.7-GHz modules, 20-MHz wide channels are centered every 5 MHz. For 2.4-
GHz modules, 20-MHz wide channels are centered every 2.5 MHz. For 5.4-GHz OFDM modules,
10-MHz wide channels can be centered every 0.5 MHz. This allows you to customize the channel
layout for interoperability where other equipment is co-located, as well as select channels with the
least background interference level.
