To put it very briefly, TETRA is a wireless communication standard for Professional Mobile Radio (PMR) and Private Access Mobile Radio (PAMR) applications. It is a digital format, in other words, speech is transmitted as binary data, which makes it far more difficult to monitor or eavesdrop. This seminar booklet reviews the market, technology, and specifications for TETRA.
