Qu'est-ce (qui) est multiple access - définition

MEANS FOR MORE THAN TWO TERMINALS TO COMMUNICATE OVER ONE MEDIUM

Multiple access; Channel access; Multiple access method; Multiple-access protocol; Channel access methods; Multiple access protocols; Multiple access protocol; Power-division multiple access; Time and Frequency division multiple access

multiple access

multiplexing

Channel access method

In telecommunications and computer networks, a channel access method or multiple access method allows more than two terminals connected to the same transmission medium to transmit over it and to share its capacity. Examples of shared physical media are wireless networks, bus networks, ring networks and point-to-point links operating in half-duplex mode.

Code Division Multiple Access

CHANNEL ACCESS METHOD FOR RADIO COMMUNICATION, ALLOWING MANY TRANSMITTERS TO SEND INFORMATION OVER ONE CHANNEL USING SPREAD SPECTRUM TECHNOLOGY AND A SPECIAL CODING SCHEME; USED IN GPS, CDMAONE, CDMA2000, UMTS, ETC.

<communications> (CDMA) (Or "spread spectrum") A form of multiplexing where the transmitter encodes the signal using a pseudorandom sequence which the receiver also knows and can use to decode the received signal. Each different random sequence corresponds to a different communication channel. Motorola uses CDMA for digital cellular phones. Qualcomm pioneered the introduction of CDMA into wireless telephone services. (2001-03-28)

Channel access method

In telecommunications and computer networks, a channel access method or multiple access method allows more than two terminals connected to the same transmission medium to transmit over it and to share its capacity. Examples of shared physical media are wireless networks, bus networks, ring networks and point-to-point links operating in half-duplex mode.

A channel access method is based on multiplexing, that allows several data streams or signals to share the same communication channel or transmission medium. In this context, multiplexing is provided by the physical layer.

A channel access method may also be a part of the multiple access protocol and control mechanism, also known as medium access control (MAC). Medium access control deals with issues such as addressing, assigning multiplex channels to different users and avoiding collisions. Media access control is a sub-layer in the data link layer of the OSI model and a component of the link layer of the TCP/IP model.
