Multiplexing
In TDM, two more streams of data appear as if they are being transferred as sub-channels
via one channel, while the truth is that they actually take turns on the single channel. What is known as the "time domain" is divided into time slots. The first byte of the first signal goes first in one time slot, and then the first byte of the second signal goes second in another time slot. The process continues until all the data has been transmitted.
TDMA is a subset of TDM in which multiple transmitters are connected to a single receiver. It's commonly used in 2G and 3G cellular systems, as well as for high-speed
local area networking over home wiring: electrical wiring, phone wiring and coaxial cable wiring. It's difficult to apply to mobile phones, however, because mobile phones often move around randomly with the caller, thus making it difficult for the transmitters to properly time their transmissions.
TDMA offers a bit more flexibility. In TDM, telecommunications multiplexing time slots are dedicated to certain users, meaning other users cannot access them. An example of this includes digital ground telephone networks. With TDMA, time slots are freed after a user logs out of the system, thus allowing other people to access those same time slots. This is the case with the Global System for Mobile Communications, or GSM, network.

What are the differences between FDM and TDM?
FDM vs. TDMTDM (Time Division Multiplexing) and FDM (Frequency Division Multiplexing) are two methods of multiplexing multiple signals into a single carrier. Multiplexing is the process of combining multiple signals into one, in such a manner that each individual signal can be retrieved at the destination. Since multiple signals are occupying the channel, they need to share the resource in some manner. The primary difference between FDM and TDM is how they divide the channel. FDM divides the channel into two or more frequency ranges that do not overlap, while TDM divides and allocates certain time periods to each channel in an alternating manner. Due to this fact, we can say that for TDM, each signal uses all of the bandwidth some of the time, while for FDM, each signal uses a small portion of the bandwidth all of the time.TDM provides greater flexibility and efficiency, by dynamically allocating more time periods to the signals that need more of the bandwidth, while reducing the time periods to those signals that do not need it. FDM lacks this type of flexibility, as it cannot dynamically change the width of the allocated frequency.The advantage of FDM over TDM is in latency. Latency is the time it takes for the data to reach its destination. As TDM allocates time periods, only one channel can transmit at a given time, and some data would often be delayed, though it's often only in milliseconds. Since channels in FDM can transmit at any time, their latencies would be much lower compared to TDM. FDM is often used in applications where latency is of utmost priority, such as those that require real-time information.FDM and TDM are often used in tandem, to create even more channels in a given frequency range. The common practice is to divide the channel with FDM, so that you have a dedicated channel with a smaller frequency range. Each of the FDM channels is then occupied by multiple channels that are multiplexed using TDM. This is what telecoms do to allow a huge number of users to use a certain frequency band.Read more: Difference Between FDM and TDM | Difference Between | FDM vs TDM http://www.differencebetween.net/technology/difference-between-fdm-and-tdm/#ixzz1x12BskVn

Difference between CDMA and tdma?
1. Their abbreviation meanings actually give light to the manner they optimize channels. TDMA is short for Time-Division Multiple Access while CDMA is for Code-Division Multiple Access. 2. TDMA emerged and was utilized first. CDMA is the more recent technology gradually replacing TDMA. 3. TDMA chops or divides the channel into sequential time portions as each user has its respective right turn for channel use. 4. CDMA uses a process called Spread Spectrum '" scattering of digital bits in pseudo-random manner and collecting them for interpretation. 5. CDMA allows numerous users to use the channel at the same time while TDMA does not.

Comparison between fdm tdm?
FDM-Frequency division multiplexing where as TDM mean Time division multiplexing.In FDM spectrum is divided into frequency whereas in TDM divided into time slot.FDM is used in 1st generation analog system whereas TDM is used in 2nd generation analog system.
What advantages does TDM have over FDM in a circuit switched network?
TDM and FDM are multiple access techniques used for multiplexing number of signals into a single single for bandwidth saving. FDM is older technique of multiplexing whereas TDM is relatively a newer technique of multiplexing. TDM advantage over FDM is that it offers bandwidth saving and there is low interference between the signals that are being multiplexed.
