Code Division Multiple Access/FrequencyDivision Dup lex (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 technique, all end users are connected to the same broadband frequency band; the desired end user is identified by a unique code. The disadvantage of this method is that bandwidth bottlenecks can occur during broadband transmissions.
