Full Duplex Wireless are hands free, simultaneous talk intercom systems. Porta Phone full duplex intercoms are unique because they work without pressbox repeaters or remote antennas. They allow coaches to communicate just like on a regular telephone.

Simplex Wireless systems are based on traditional push to talk operation. When a coach speaks, the message is received by all radios set to the same frequency. Channel switching makes it easy to accommodate the talking pattern needs of any staff.
