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 In this section, we discuss three channelization protocols: FDMA, TDMA, and CDMA

Frequency-Division Multiple Access (FDMA)

1 0 2 i

In frequency-division multiple access (FDMA), the available bandwidth is divided into frequency bands Each station is allocated a band to send its data In other words, each band is reserved for a specific station, and it belongs to the station all the time Each station also uses a bandpass filter to confine the transmitter frequencies To prevent station interferences, the allocated bands are separated from one another by small guard bands Figure 1221 shows the idea of FDMA Figure 1221

In FDMA, the available bandwidth of the common channel is divided into bands that are separated by guard bands

1011 1012 1021 1022

FDMA specifies a predetermined frequency band for the entire period of communication This means that stream data (a continuous flow of data that may not be packetized) can easily be used with FDMA We will see in 16 how this feature can be used in cellular telephone systems We need to emphasize that although FDMA and FDM conceptually seem similar, there are differences between them FDM, as we saw in 6, is a physical layer technique that combines the loads from low-bandwidth channels and transmits them by using a high-bandwidth channel The channels that are combined are low-pass The multiplexer modulates the signals, combines them, and creates a bandpass signal The bandwidth of each channel is shifted by the multiplexer FDMA, on the other hand, is an access method in the data link layer The data link layer in each station tells its physical layer to make a bandpass signal from the data passed to it The signal must be created in the allocated band There is no physical multiplexer at the physical layer The signals created at each station are automatically bandpass-filtered They are mixed when they are sent to the common channel

Time-Division Multiple Access (TDMA)

In time-division multiple access (TDMA), the stations share the bandwidth of the channel in time Each station is allocated a time slot during which it can send data Each station transmits its data in is assigned time slot Figure 1222 shows the idea behind TDMA

:

The main problem with TDMA lies in achieving synchronization between the different stations Each station needs to know the beginning of its slot and the location of its slot This may be difficult because of propagation delays introduced in the system if the stations are spread over a large area To compensate for the delays, we can insert guard

times Synchronization is normally accomplished by having some synchronization bits (normally refened to as preamble bits) at the beginning of each slot

We also need to emphasize that although TDMA and TDM conceptually seem the same, there are differences between them TDM, as we saw in 6, is a physical layer technique that combines the data from slower channels and transmits them by using a faster channel The process uses a physical multiplexer that interleaves data units from each channel TDMA, on the other hand, is an access method in the data link layer The data link layer in each station tells its physical layer to use the allocated time slot There is no physical multiplexer at the physical layer
