What is the main difference between FDMA and TDMA?

FDMA separates users by frequency — each user occupies its own radio channel. TDMA separates users by time — each user occupies the entire radio channel, but at different time slots.

What is TDMA FDMA and CDMA?

FDMA stands for Frequency Division Multiple Access. TDMA stands for Time Division Multiple Access. CDMA stands for Code Division Multiple Access. In this, sharing of bandwidth among different stations takes place. In this, only the sharing of time of satellite transponder takes place.

Which is better FDMA and TDMA?

FDMA only requires the guard bands between adjacent channels, whereas TDMA requires the guard time of the adjacent slots. On the other hand, CDMA requires both guard time and guard bands. FDAM has a low data rate, whereas TDMA has a medium data rate.
