Detailed explanation-1: -Channelization is a multiple-access method in which the available bandwidth of a link is shared in time, frequency, or through code, between different stations.
Detailed explanation-2: -CDMA is an example of multiple access, where several transmitters can send information simultaneously over a single communication channel. This allows several users to share a band of frequencies (see bandwidth).
Detailed explanation-3: -Time Division Multiple Access (TDMA) is a channel access method. It allows the same frequency bandwidth to be shared across multiple stations. And to avoid collisions in the shared channel, it divides the channel into different frequency slots that allocate stations to transmit the data frames.
