What is Time Division Multiple Access?

Time division a couple of get right of entry to (TDMA) is a channel get entry to approach (CAM) used to facilitate channel sharing without interference. TDMA allows multiple stations to percentage and use the identical transmission channel by using dividing alerts into different time slots. Users transmit in fast succession, and each one Makes use of its very own time slot. Thus, multiple stations (like mobiles) might also proportion the same frequency channel however best use part of its capability.

What Does Time Division Multiple Access Mean?

Examples of TDMA consist of IS-136, Personal virtual mobile (PDC), incorporated Digital improved commUnity (iDEN) and the second generation (2G) Global System for Mobile Communications (GSM).

TDMA lets in a Cellular station’s radio element to concentrate and broadCast handiest in its assigned time slot. During the closing term, the mobile station might also apply Network measurements with the aid of detecting surrounding Transmitters in one of a kind frequencies. This feature permits interfrequency Handover, which differs from Code division more than one get entry to (CDMA), where frequency handover is hard to obtain. However, CDMA permits Handoffs, which permit mobile stations to conCurrently communicate with up to six Base Stations.

TDMA is utilized in maximum 2G Cellular sySTEMs, even as 3G systems are based totally on CDMA. However, TDMA stays relevant to Modern structures. For Instance, blended TDMA, CDMA and Time Division Duplex (TDD) are regular terrestrial radio get admission to (UTRA) structures that permit multiple users to percentage one time slot.
