Remote AP Deployment
In cases where the subscriber population is widely distributed, or conditions such as geography restrict
network deployment, you can add a Remote AP to:
• provide high-throughput service to near LoS business subscribers.
•
reach around obstructions or penetrate foliage with non-LoS throughput.
• reach new, especially widely distributed, residential subscribers with broadband service.
• pass sync to an additional RF hop.
In the remote AP configuration, a remote AP is co-located with an SM. The remote AP distributes the
signal to SMs that are logically behind the co-located SM. A remote AP deployment is illustrated in
Figure 62 .
Figure 62 Remote AP deployment
The co-located SM receives data in one channel, and the remote AP must redistribute the data in a
different channel. The two channels need to have a frequency gap equal to at least two times the used
channel bandwidth.
Base your selection of frequency band ranges on regulatory restrictions, environmental conditions, and
throughput requirements.
Note
Each relay hop (additional daisy-chained remote AP) adds approximately 5-7 msec round
trip latency.
