Question

Does bandwidth gets divided in tdma?

How does bandwidth gets affected in fdma, tdma, cdma

Answer 1

In time-division multiple access (TDMA), the bandwidth of a communication channel is divided into time slots, and each user is assigned a specific time slot to transmit. This allows multiple users to share the same channel and communicate simultaneously, effectively dividing the bandwidth among the users.

In frequency-division multiple access (FDMA), the bandwidth of a channel is divided into frequency bands, and each user is assigned a specific frequency band to transmit. This also allows multiple users to share the same channel and communicate simultaneously, dividing the bandwidth among the users.

In code-division multiple access (CDMA), multiple users can transmit simultaneously on the same frequency by using unique codes to distinguish their signals. CDMA does not explicitly divide the bandwidth among users but rather allows multiple users to share the same frequency band by encoding their signals with unique codes.

In all three multiple access techniques (FDMA, TDMA, and CDMA), the bandwidth is effectively divided among multiple users to allow them to communicate simultaneously over a shared channel.

Answer 2

Yes, bandwidth gets divided in TDMA (Time Division Multiple Access). In TDMA, multiple users are allocated a specific time slot in which they can send and receive data. This divides the available bandwidth among the users and allows them to send and receive data without interference from other users on the network. As for FDMA (Frequency Division Multiple Access), CDMA (Code Division Multiple Access), and TDMA, these all reduce the total available bandwidth by dividing it among users, allowing each user to use only a portion of the bandwidth. In FDMA, each user is assigned a specific frequency band within the available spectrum; in CDMA, each user is assigned a unique code to identify their transmissions
