Spelling: TDMA
TIME DIVISION MULTIPLE ACCESS
A digital transmission technology that allows a number of users to
access a single RF channel without interference by allocating unique
time slots to each user. The TDMA digital transmission scheme
multiplexes three signals over a single channel. The current TDMA
standard for cellular networks divides a single channel into six time
slots, with each signal using two slots, providing a 3 to 1 gain in
capacity over the advanced mobile-phone service. Each caller is
assigned a specific time slot for transmission.
It is one of the oldest digital mobile phone technologies and it only
commonly used in the USA.
Specified in EIA/TIA Interim Standard 54 then enhanced on in IS-136
Don't confuse with CDMA [1]!
