The 5 GHz modules provide a sustained aggregate throughput of up to 126 Mbps to the sector. One of the
SMs in the sector is wired to a 900-MHz remote AP, which provides NLoS sustained aggregate
throughput

of:

126 Mbps to 900-MHz SMs up to 4 miles away in the sector.
l
94 Mbps to 900-MHz SMs between 4 and 10 miles away in the sector.
Exam p le Use Case f or Passing Sync
All radios support the remote AP functionality. The BHS and the SM can reliably pass the sync pulse, and
the BHM and AP can reliably receive it.
However, not all devices are compatible with all other devices. The following table shows which SMs can
be connected to which APs.
Devices PMP 450 AP/BHM PMP 450i AP/BHM PMP 450m AP
PMP 450 SM/BHS X
PMP 450i SM/BHS X X
Examples of passing sync over cable are shown under Passing Sync in an Additional Hop.
For PMP 450, the sync is passed in a cable that connects Pins 1 and 6 of the RJ-11 timing ports of the two
modules.
For PMP 450i/450m the sync is passed in a cable that connects Pins7 and 8 of the RJ-45 timing ports of
the two modules.
When connecting modules in this way, make sure the AP and SM are properly configured, as described in
the Wiring to Extend Network Sync.
Physical Connect ions Involving t he Rem ot e A P
The SM to which a remote AP is connected to can be either an SM that serves a customer or an SM that
simply serves as a relay. If the SM serves a customer, wire the remote AP to the SM as shown in Remote AP
