Time division multiple access
method of cellular communications which allows alternating transmission on one channel by dividing time into "slices" and giving one "slice" to every transmission
Time Division Multiple Access An advanced digital cellular platform that converts audio signals into a stream of digital information (made up of 1s and 0s) and divides it into "digital speech packets" according to time The packets are then transmitted one a single radio frequency TDMA differs from the other popular digital cellular platform, CDMA, in that it uses one channel instead of many These digital platforms ensure greater call clarity and security, prevent cloning fraud and allow a greater number of calls to be handled by a tower or response center at one time
Time Division Multiple Access 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 Available in either 800 or 1900 MHz frequencies
Time Division Multiple Access is a digital transmission format used for D-AMPS and GSM format
Time Division Multiple Access A method allowing multiple carriers to share a single satellite transponder or range of frequencies The earth stations transmit sequentially in unique time slots at the same carrier frequency, so that only a single station transmits at any given time
[telecommunications] Time- Division Multiple Access A wire- less communication method that divides the designated frequency into time slots Each frequency can carry multiple transmissions, with each call taking a "turn" in a time slot Mobile TDMA handsets tend to have better sound quality than those using the code-division (CDMA) method, but require more battery power to remain on the designated frequency
Time Division Multiple Access, the magical technique used by the digital GSM network to squeeze more calls onto one channel by dividing a calling channel into a few "discontinuous" pieces
(Time Division Multiple Access) refers to a digital RF link where multiple phones share a single carrier frequency by taking turns Each phone gets the channel exclusively for a certain time slice, then gives it up while all the other phones take their turn TDMA is also used sometimes to refer specifically to the standard covered by IS-136, which is a source of confusion because GSM also uses a TDMA air interface, as does IDEN, and neither of those systems are compatible with IS-136
Time Division Multiple Access TDMA systems are able to transmit multiple voice circuits per channel A TDMA channel is a single FDMA channel divided up in time into multiple time slots Three users can take it in turn to share one radio channel The channels can vary in bandwidth and depending on the type of system, the time slots can transmit all or part of a voice circuit Each user's speech is stored, compressed and transmitted as a quick packet, using controlled time slots to distinguish them-hence the phrase 'time division' Its uses 30 KHz channels and a vocoder rate of 8 Kbits/sec At the receiver, the packet is decompressed
Time Division Multiple Access: A digital air interface technology used in cellular, PCS and ESMR networks
TDMA (Time Division Multiple Access) is a digital mobile phone network that operates in the US, Latin America, New Zealand, parts of Russia and Asia Pacific Ericsson's TDMA mobile phones also work on AMPS networks Networks using TDMA assign 6 timeslots for each frequency channel Devices using the wireless network send bursts of information that are reassembled at the receiving end Back to the top
Time Division Multiple Access - A digital air interface technology used in cellular, PCS and ESMR networks
(Time Division Multiple Access) TDMA is 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
1 Time Division Multiple Access: a digital wireless telephony transmission technique TDMA allocates each user a different time slot on a given frequency GSM, D-AMPS, PDC and DECT use TDMA in one form or another 2 A name generally used for D-AMPS TDMA networks are operated in the US, Latin America, New Zealand, parts of Russia and Asia Pacific D-AMPS, GSM, PDC, AMPS
Time Division Multiple Access A technology for digital transmission of radio signals between, for example, a mobile phone and a radio base station In TDMA, the frequency band is split into a number of channels that are stacked into short time units so that several calls can share a single channel without interfering with one another 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 See also IS-136 and D-AMPS
– Time Division Multiple Access, a method of accessing a satellite using time separation, sending simultaneous data streams interleaved using a clock to separate the various data packets
Time division multiple access A digital radiocommunications access multiplexing technique that interleaves multiple signals on a single radiofrequency channel in a rotated sequence of time slots, with each user exclusively accessing the channel at any one time The technique used by GSM mobile telecommunications
Time Division Multiple Access -- This is a method of dividing one carrier between many users, by individually handling several signals from different Earth Stations
Time Division Multiple Access Standard used mainly by carriers such as AT&T, Suncom, Cellular One
(time division multiple access): A digital air interface technology used in cellular, PCS and ESMR networks
A technology used in digital cellular telephone communication to divide each cellular channel into a number of time slots in order to increase the amount of data that can be carried This technology is called multiplexing TDMA is used by Digital-American Mobile Phone Service (D-AMPS), Global System for Mobile communications (GSM), and Personal Digital Cellular (PDC) TDMA is implemented within each of these systems differently An alternative multiplexing scheme to TDMA is code division multiple access (CDMA), which takes the entire allocated frequency range for a given service and multiplexes information for all users across the spectrum range at the same time The TDMA standard was first specified in Interim Standard 54 (IS-54) The U S uses IS-136 for TDMA for both the cellular (850 MHz) and PCS (1900 MHz) spectrums TDMA is also used for Digital Enhanced Cordless Telecommunications (DECT)
Time Division Multiple Access: A method of digital wireless communications transmission allowing 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 (Back to top )
