Voice over 802.11

An understanding of the public switched telephone network (PSTN) and how it is potentially going to be replaced is best grasped by understanding its three major components: access, switching, and transport. Access pertains to how a user accesses the network. Switching refers to how a call is “switched” or routed through the network, and transport describes how a call travels or is “transported” over the network.
