12.9.3 AvoidingOtherInterference
Where signal strength cannot dominate noise levels, the network experiences
• bit error corrections.
• packet errors and retransmissions.
• lower throughput (because bandwidth is consumed by retransmissions) and high
latency (due to resends).
Be especially cognitive of these symptoms for 900-MHz links. Where you see these
symptoms, attempt the following remedies:
• Adjust the position of the SM.
• Deploy a band-pass filter at the AP.
• Consider adding a remote AP closer to the affected SMs. (See Deploying a
Remote AP on Page 148.)
Certain other actions, which may seem to be potential remedies, do not resolve high
noise level problems:
• Do not deploy an omnidirectional antenna.
• Do not set the antenna gain above the regulated level.
• Do not deploy a band-pass filter in the expectation that this can mitigate co-
channel interference.
