When designing a WLAN network to support both voice and context-aware services, which set of
design principles should you follow?

A.
A voice and context-aware site survey can be one survey, and both voice and context-aware
deployment recommendations can be implemented. APs that are not serving clients will be in
monitor mode.

B.
A context-aware site survey usually recommends deploying more APs because of the
requirement for perimeter coverage and four corners of a floor. However, voice deployment
recommendations should be adopted because of the mission-critical nature of voice traffic.

C.
A voice and context-aware site survey can be one survey, but voice deployment
recommendations take precedence over context-aware deployment recommendations because
the context-aware survey usually recommends too many APs and might introduce too much cochannel interference, negatively affecting voice quality.

D.
A voice and context-aware site survey can be one survey, but context-aware deployment
recommendations take precedence over voice deployment recommendations because contextaware services require at least four APs to hear clients or tags at -75 dBm. An AP can provide
adequate coverage to voice clients with acceptable SNR.

E.
A voice and context-aware site survey can be one survey, but voice deployment
recommendations take precedence over context-aware deployment recommendations. Contextaware surveys usually recommend too many APs, and APs need to be in local mode because APs
in monitor mode spend too much time (2 sec) on each channel, listening for rogue activities, and
often miss client or tag beaconing.
