TDMA is the acronym for Time Division Multiple Access. One of two major protocols (the other is CDMA) for digital cellular telephony that enables multiple callers to share the same channel by giving each phone a specified time slot in which it may transmit or receive.
TDMA operates at 800 MHz or 1900 MHz; and when operating at the higher frequency, it enables Personal Communication Services (PCS) such as paging, text-based Internet access by means of the Wireless Applications Protocol (WAP), and voice mail. TDMA also enables data communications at a transfer rate of 14.4 Kbps. U.S. Service providers include AT&T Wireless and Nextel.
Technipages Explains TDMA
TDMA is an advanced innovation that requires a precise synchronization between the transmitter and the beneficiary. TDMA is utilized in advanced portable radio frameworks. The individual versatile stations consistently dole out a recurrence for the select utilization of an interim period.
In the greater part of the cases, the whole framework data transfer capacity for an interim period of time isn’t allocated to a station. Be that as it may, the recurrence of the framework is separated into sub-groups, and TDMA is utilized for the different access in each sub-band. Sub-groups are known as bearer frequencies. The versatile framework that uses this method is alluded as the multi-bearer frameworks.
TDMA was first utilized in satellite correspondence frameworks by Western Union in its Westar 3 interchange satellite in 1979. It is presently utilized widely in satellite interchanges, battle net radio frameworks, and latent optical system (PON) systems for upstream traffic from premises to the administrator and for use of Dynamic TDMA parcel mode correspondence.
Common Uses of TDMA
- TDMA rates are very flexible, which implies that several slots can be allocated to a user
- The number of slots for TDMA can be changed frame by frame
- No guard band is required for the TDMA wideband system
Common Misuses of TDMA
- TDMA is an automotive technology developed by the Nazi
