XYZ Company is planning to install a new 802.11 WLAN, but wants to upgrade its wired
infrastructure first to provide the best user experience possible. XYZ has hired you to perform the
RF site survey. During the interview with the network manager, you are told that the new Ethernet
edge switches will support VoIP phones and 802.11 access points, both using 802.3af PoE.
After hearing this information, what immediate concerns do you note?
VoIP phones and 802.11 access points should not be powered by the same edge switch due to
The edge Ethernet switches will need to support 802.3at PoE in order to support both access
points and VoIP phones.
If the switches are in optimal locations for VoIP phones, they are likely to be suboptimal
locations for 802.11 APs.
The power budget in the edge switches must be carefully planned and monitored based on the
number of supported PoE devices.
