Multiple Access Techniques Space Division Multiple Access:- used for
allocating space to users
Frequency Division Multiple Access:- comprises all algorithms allocating frequencies to transmission channel according to FDM
Time Division Multiple Access:- comprises technologies which allocate time slots for communication i.e., controlling TDM
FDMA + TDMA
