code division multiple access/frequency diversity duplex (MMDS) (CDMA/FDD)
Code Division Multiple Access/Frequency Division Duplex(CDMA/ FDD) is used in Wireless Local Loops(WLL), namely in MMDS for exclusive wireless duplex connections in the connection area.
The CDMA/FDD technique is equivalent to IS-95 CDMA. In this method, all end users are connected to the same broadband frequency band; the desired end user is identified by a unique code. A disadvantage of this method is that bandwidth bottlenecks can occur during broadband transmissions.
