Cisco Adaptive wIPS Introduction

In sharp contrast, the diagram below depicts an indoor environment with numerous heavy walls, which
cause signal attenuation. In this case, more wIPS Access Points will need to be deployed to ensure that
attacks are picked up.

Frequency Band(s) Monitored

The radio frequency propagation characteristics of the 2.4GHz and 5GHz bands vary as a result of the
wavelength differences between the two. Put simply, 2.4GHz wireless signals (802.11b/g/n) travel a
further distance than 5GHz (802.11a/n). In order to accurately compute the number of wIPS access
points needed for a prospective installation, one must consider what frequency bands must be monitored
in the wIPS deployment.
