Abstract
A switched wireless system is used to increase the range of peer-to-peer communications. The optically-switched fiber optic communication system includes a head-end unit (HEU) having a switch bank. Cables couple the HEU to one or more remote access points in different coverage areas. The switch bank in the HEU provides a link between the remote access points in the different coverage areas such that devices in the different cellular coverage areas communicate with each other, such as through videoconferencing. By using the switched communication system, the range and coverage of communication between devices may be extended such that devices in different coverage areas and devices using different communication protocols can communicate.
