QuestionQ4

Campus and Branch LAN Design

You need to establish how far apart access points that operate on the same channel should be located.

In this scenario, what signal strength is recommended for determining that spacing?

  • A −30 dBm
  • B −10 dBm
  • C −5 dBm
  • D −65 dBm
Explanation

A −65 dBm RSSI threshold is a standard WLAN planning value for defining usable cell coverage and managing separation between access points. Designing same-channel AP placement around this level helps limit excessive co-channel overlap while preserving reliable client coverage.
