Time Division Multiple Access Question & Answers June 20, 2022 By WatElectronics This article lists 50 Time Division Multiple Access MCQs for engineering students. All the Time Division Multiple Access Questions & Answers given below include a hint and a link wherever possible to the relevant topic. This is helpful for users who are preparing for their exams, or interviews, or professionals who would like to brush up on the fundamentals of Time Division Multiple Access. TDMA stands for Time division multiple access. TDMA is used in digital cellular communication systems and it enables multiple users to share the same frequency by dividing each channel into different time slots. TDMA is used in telecommunication and GSM-based systems, and digital mobile radio systems. TDMA is a complex technology in which accurate synchronization is required between transmitter and receiver. The period slots combined are called TDMA frames. It allows flexible rates, it doesn’t require guard band filters and narrow band filters for wideband systems. The number allocated to the user can be changed frame by frame, it holds variable bit rate traffic. Due to high operating bit rates, it increases energy consumption. TDMA is used for multiple access in each sub-band. Sub-bands are known as carrier frequencies. TDMA requires synchronization between different stations. It is a type of access method in the data link layer. Each data link layer tells the station to use the allocated time slot. No need for a codeword. Guard time of the adjacent slots is necessary. The mode of data transfer is signal in bursts. It is moderately flexible. 1). TDMA Stands for ______?
