What is the difference between each of the wireless technologies (TDMA, CDMA and GSM)?
A. TDMA (Time Division Multiple Access), CDMA (Code Division Multiple Access), and GSM (Global Systems for Mobile Communication) are three types of wireless transmission technologies. TDMA offers an immediate increase of three times the system capacity allowed by AMPS (Analog Mobile Phone System) with the potential to increase even more as the technology is enhanced. TDMA achieves this increased capacity by digitizing call data, assigning it to a channel, then distributing the data into three of six time slots on the channel and re-assembling it back to voice on the other end. CDMA works by tagging digitized segments of a conversation with a unique code, allowing the segment to occupy a broad range of frequencies that are re-assembled into voice at the other end by having the correct code.
