Date: January 2008
Type: White Paper
Rating: (0)

Overview: A novel approach for providing professional quality telephony over WLANs is discussed in this. The approach is to merge the upper layers of the DECT protocol stack with the WLAN physical layer and MAC layer technology, using a protocol adaptation layer (PAL). This allows retaining many of the professional quality features of DECT while using the ubiquitous WLAN standards. Such an approach has advantages in terms of the high quality of voice, seamless handovers, low complexity, advanced power saving and a high degree of standardization leading to fewer interoperability problems.
