Time Division Multiple Access
ime ivision ultiple ccess. (1) a technique to increase capacity using voice compression and multiple time slots on a radio channel. (2) TIA IS-136 standard for TDMA mobile systems in AMPS environment.
TDMA is one of the most common digital communication technologies. It divides a sequence of conversations into packets of data according to time. It is offered in several bandwidths, typically 800 MHz and 1900 MHz and requires a TDMA phone. Along with GSM TDMA offers slower data bandwidth for wireless data connection (typically 9.6 Kbps) while CDMA usually allows for 14.4 Kbps.
Time Division Multiplexing is a technique for multiplexing multiple users onto a single channel on a single carrier by splitting the carrier into time slots and allocating these on as-needed basis.
A technique used to share the same bandwidth between different channels using periodic time slots. TDMA divides frequency bands available to the network into time slots, with each user having access to one time slot at regular intervals. TDMA thereby makes more efficient use of available bandwidth than the previous generation AMPS technology. Used on either 800 or 1900 MHz frequency bands.
A method of digital wireless communications transmission that allows a large number of users to access (in sequence) a single radio frequency channel without interference by allocating unique time slots to each user within each channel. Rather than encoding bits of data like CDMA, each frequency is broken into time slots through which bits of data flow. Data can only flow in their assigned time slots. TDMA is used in second generation wireless phone systems, such as GSM and D-AMPS; the latter often is called TDMA.
A technology that transmits information by dividing calls into time slots, each one lasting only a fraction of a second. Each call is assigned a specific portion of time on a designated channel. By dividing each call into time ‘packets,' a single channel can carry many calls at once.
Refers to a form of multiple access where a single carrier is time shared by many users. Signals from earth stations reaching the satellite consecutively are processed in time segments without overlapping.
This protocol allows large numbers of users to access one radio frequency by allocating time slots for use to multiple voice or data calls. TDMA breaks down data transmission, such as a phone conversation, into fragments and transmits each fragment in a short burst, assigning each fragment a time slot. With a cell phone, the caller would not detect this fragmentation. Whereas CDMA (which is used more frequently in the United States) breaks down calls on a signal by codes, TDMA breaks them down by time. The result in both cases: increased network capacity for the wireless carrier and a lack of interference for the caller. TDMA works with GSM and digital cellular services.

Divides voice and data transmissions into packets according to time, allowing multiple transmissions on a signal frequency.
Time Domain Multiple Access. Near-synonym for TDD.
A wireless technology that allows for digital transmission of radio signals between a mobile device and a fixed radio base station. It allows for increased bandwidth over digital cellular networks.
A technology used in digital cellular telephone communication to divide each cellular channel into three time slots in order to increase the amount of data that can be carried.
divides cellular channels into three time slots, increasing data capacity. This lets multiple users or conversations to be carried on the same channel.
A method of digital wireless communications transmission allowing a large number of users to access a single radio-frequency channel without interference. Each user is given a unique time slot within each channel. SMS Mobile Originate has now gone live on several TDMA networks around the world including Telecom New Zealand, Midwest Wireless USA, Algar Telecom Brazil and Cellcom Israel. Other TDMA network operators such as AT&T Wireless in the U.S. have launched SMS MO nationally.
Short for ime- ivision ultiple ccess, a technology for delivering digital wireless service using time-division multiplexing (TDM). TDMA works by dividing a radio frequency into time slots and then allocating slots to multiple calls. In this way, a single frequency can support multiple, simultaneous data channels. TDMA is used by the GSM digital cellular system.
TDMA is the acronym for Time Division Multiple Accesses, referring to a digital transmission format used for D-AMPS and GSM format.
A technology for digital transmission of radio signals between, for example, a mobile telephone and a radio base station. In TDMA, the frequency band is split into a number of channels which in turn are stacked into short time units so that several calls can share a single channel without interfering with one another. Networks using TDMA assign 6 timeslots for each frequency channel. TDMA is also the name of a digital technology based on the IS-136 standard. TDMA is the current designation for what was formerly known as D-AMPS.
A wireless digital technology designed to increase channel capacity by separating each wireless call's signal into pieces and assigning each one piece to a time slot that lasts a fraction of a second. Using TDMA, a single voice connection can be used to handle up to three wireless phone conversations simultaneously.
"TDMA" has been adopted as the new name for the "Digital AMPS" (D-AMPS) mobile standard, now called ANSI-136, used in the Americas, Asian Pacific and other areas. TDMA services can be delivered in the 800 MHz and 1900 MHz frequency bands.
A digital air interface technology used in cellular, PCS and ESMR networks. TDMA allows a large number of users to access a single radio frequency channel without interference by allocating unique time slots to each user within each channel.
A multiple-access technique in which you first divide the available or allocated frequency spectrum into a number of channels. Then, within each channel you apply TDM to carry multiple users interleaved in time.
Time-Division Multiplex Access. A type of multiplexing in which two or more channels of information are transmitted over the same link, where the channels take turns to use the link. Each link is allocated a different time interval ("slot" or "slice") for the transmission of each channel. For the receiver to distinguish one channel from the other, some kind of periodic synchronizing signal or distinguishing identifier is required. See also GSM.
