Issues of Voice over Wi-Fi

1. 802.11 QoS

absence—until very recently—of a standards-based solution for prioritizing

2. Fast Hand-off between APs

re-authentication between APs takes time such that voice suffers.

Product Solution : "UltraThin" access points (APs) & packet-by-packet micro-management of multiple data streams means that adjacent APs are never broadcasting at the same time

segregate different types of traffic (e.g., voice and data) on different radios, completely eliminating the 'contention' issue or need to prioritize traffic

background: Wi-Fi—802.11b and 802.11g—there are only three non-overlapping channels
