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

A.
An AP must be placed at the perimeter and in each of the four corners of the floor. All APs must
be enabled to ensure proper coverage on the floor to provide -67 dBm, 20 percent celloverlap, and
19 dB channel separation.

B.
An AP must be placed at the perimeter and in each of the four corners of the floor. Some APs may
be disabled to ensure proper coverage on the floor to provide -67 dBm, 20 percent celloverlap, and
19 dB channel separation.

C.
An AP must be placed at the perimeter and in each of the four corners of the floor to ensure
proper coverage on the floor to provide -67 dBm, 20 percent cell overlap, and 19 dB channel
separation. Some APs may be in monitor mode.

D.
If a conflict occurs between the AP placement for voice design and for context-aware location
design, then the voice design should take precedence, to protect against delays and dropping of
sensitive voice traffic.

E.
In a design that includes both voice and context-aware services, voice design always requires
more APs to be deployed to ensure -67 dBm coverage, 20 percent cell overlap, 19 dB channel
separation, and proper capacity planning.

F.
In a design that includes both voice and context-aware services, voice design should take
precedence to avoid co-channel interference, which can negatively affect voice quality. Voice design
also requires -67 dBm coverage, 20 percent cell overlap, and 19 dB channel separation, which is
more difficult to achieve.
