RFI can be generated by a wide variety of sources including electronic organs, computers, switching power supplies, broadcast radio signals and outside radio devices. Radio signal energy can enter a sound system component or alter the audio signals in cabling, producing annoying hiss, whining or intelligible audio signals. Proper shielding and balanced audio cabling are the best defense against RFI problems in a sound system. High quality receivers are the best defense against RFI in wireless microphone systems.

Target Cell
The cell that a mobile is going to during the hand off process..

TPC
Three Party Conference Circuit. Used in three party conference, but more importantly, used during every handoff so that the channel-change transition can be made with less noise by connecting the audio of the source and target cells together before the hand off order is sent. (When a handoff is made during a three-party conference call, and the TPC is being used, 'hard-handoffs' exists and the potential for noise during channel changes increases significantly)

TDMA
Time Division Multiple Access. TDMA systems are able to transmit multiple voice circuits per channel. A TDMA channel is a single FDMA channel divided up in time into multiple time slots. Three users can take it in turn to share one radio channel. The channels can vary in bandwidth and depending on the type of system, the time slots can transmit all or part of a voice circuit. Each user's speech is stored, compressed and transmitted as a quick packet, using controlled time slots to distinguish them-hence the phrase 'time division'. Its uses 30 KHz channels and a vocoder rate of 8 Kbits/sec. At the receiver, the packet is de-compressed.

Target Channel Falsing
A condition that exists when co-channel SAT exists on the target channel during handoff, so that target channel does not squelch before arrival of the mobile during the handoff process. This results in noise during the handoff process (before the handoff order) that can be heard by both the landline and mobile parties.
