The ABCs of TDMA Technology

Time division multiple access (TDMA) is digital transmission technology that allows a number of users to access a single radio-frequency (RF) channel without interference by allocating unique time slots to each user within each channel. The TDMA digital transmission is efficiency because it divides each channel into multiple time slots. Each transmitter is assigned a specific time slot for transmission. Therefore, this advanced technology can prevent collision and save your time for data transmission.

The ABCs of CSMA Technology

Another technology, Carrier sense multiple access (CSMA) based wireless networks are often used to connect multiple wireless devices. In CSMA based networks, the time instance at which a wireless device in a CSMA network may transmit a data packet generally depends on a determination of whether the communication channel is free. In general, waiting for too long a time, due to false detection may reduce overall throughput. On the other hand, transmitting too early, may cause a collision with a valid data packet already present in the channel and result in violation of the protocol.
