TDMA frame structure showing a data stream divided into frames and those frames divided into time slots. Time-division multiple access (TDMA) is a channel access method for shared-medium networks. It allows several users to share the same frequency channel by dividing the signal into different time slots. [1]
TDMA may refer to: TDMA, an MDMA analogue; Time-division multiple access, a channel-access scheme; Tridiagonal matrix algorithm, a mathematical system;
MF-TDMA ("Multi-frequency time-division multiple access") is a technology for dynamically sharing bandwidth resources in an over-the-air two-way communications network. See also [ edit ]
Time-division multiple access (TDMA) divides a channel into frames, which furthermore are subdivided into a vast number of time slots. Users transmit in rapid succession, one after the other, each using their own time slot. One of the drawbacks of TDMA is that it requires a central station for slot assignment and time synchronization.
Time-division multiplexing (TDM) is a method of transmitting and receiving independent signals over a common signal path by means of synchronized switches at each end of the transmission line so that each signal appears on the line only a fraction of time according to agreed rules, e.g. with each transmitter working in turn.
OFDMA can be seen as an alternative to combining OFDM with time-division multiple access (TDMA) or time-domain statistical multiplexing communication. Low-data-rate users can send continuously with low transmission power instead of using a "pulsed" high-power carrier. Constant delay, and shorter delay, can be achieved.
The Vietnam Internet Network Information Center (VNNIC; Vietnamese: Trung tâm Internet Việt Nam, lit. 'Internet Center of Vietnam') is the National Internet Registry in Vietnam that manages several aspects of Internet operations, including the allocation of IP addresses and AS numbers. VNNIC is the administrative agency responsible for ...
Zing Me is a social network operated by VNG, introduced in August 2009. It is integrated directly via the Zing system, with a variety of special applications like blogging, photo and music sharing, gaming, video clips, and email. In addition, Zing Me was the first social network in Vietnam that had the properties of a platform.
