Re: TDMA AND FDMA
in terms of bandwidth, TDMA allocates the whole channel bandwidth for a specific user, but only for a specified period of time, called a time slot. after a certain time slot, the whole channel bandwidth is used by another user. so its one user at a time.
in the case of FDMA, the whole channel bandwidth is divided into smaller channels assigned to each user. the user can use the channel allocated to it anytime it wants to. but at a smaller bandwidth.
