Voice over 802.11 (Vo802.11)
Segueing from QoS is the concept of routing voice traffic over 802.11 networks. The focus on QoS
makes routing voice over 802.11 possible. Here is another performance parameter where 802.11 must
match the capabilities of the PSTN in order for the technology to achieve wide acceptance. The Vo802.11
industry is very much in its infancy and is largely limited to in-building enterprise applications interfacing
with conventional private branch exchanges (PBXs). However, some case studies point to the use of
802.11 to transmit voice point to point in a range of 19 miles. This is service that competes directly with
the telephone company's Last Mile monopoly. The advent of softswitch technologies and Internet
Protocol (IP) backbones makes it entirely possible to route phone calls that never touch the PSTN.
