Hello Friends! In this article, we will know about the Medium Access control and we always try to best content available for you. So let's start...
SDMA(Space Division Multiple Access ):--
it is a Multiple input and output of a multiple antennae systematic architecture, suitable for mobile haddock network which unable access to communication channels by identifying user location and establishing a one to one mapping b/w network bandwidth division identify space location.
FDMA(Frequency Division Multiple Access):--
FDMA is a division of frequency band allocated for wireless cellular phone communication into 30 channels each of which carries a voice conversation or with digital service carry digital data. FDMA is a basic technology in the analog advanced mobile phone service. the most widely installed cellular phone system installed in North America with FDMA each channel can be assigned to only one user at a time.

TDMA(Time Division Multiple Access):--
TDMA improves spectrum capacity by Splitting each frequency into time slots TDMA allows each user to access the entire radio frequency channel for a short period of a call other users share this same frequency channel at different time slots. TDMA is the dominant technology for second-generation mobile cellular networks using TDMA assign frequency channels. devices using the wireless network send information that is resembled at receiving end.
CDMA (Code Division Multiple Access):--
for cellular phone users, CDMA is a transparent interface for a wireless digital network. CDMA was originally developed by the military in the early 1960 CDMA uses sequentially code frequencies to funnel traffic channels within the same radio channel for a nontechnical definition CDMA channels the packets of voice and data over wireless radio frequencies. so a cellular user can hare better, quickly and with more quality than over before CDMA cell phones are also more efficient has the use channels "Band Width" efficiently.
