Access Points

802.11a, b, and g APs provide the connection between the wired Ethernet LAN and the wireless
(802.11) LAN. APs must be positioned in all areas where the wireless handsets are used. The
number and placement of APs affect the coverage area and capacity of the wireless system.
Typically, the requirements for use of handsets are similar to that of other wireless data devices.
The APs must be either SVP-compliant or WMM-compliant to support QoS. For for information
about supported APs, see

Handset switchover

If a user on an active call is moving about, the call switches from AP to AP in the subnet. This
changeover is transparent to the user.
Important:
Wireless handsets cannot roam with uninterrupted service between subnets unless specific
LAN components are present. Certain AP/Ethernet switch combinations establish a Layer-2
tunnel across subnets that enable the handsets to roam. Without this capability, any call in
