Code-division
multiple access refers
to any of several protocols used in 2G
and 3G communications. It allows
numerous signals to occupy a single
transmission channel, optimising the
availability of bandwidth.

Kanallarni kod bo‘yicha ajratish
jarayoni ko‘plab vaqt slotlari
bo‘ylab amalga oshirishni
ta’minlaydigan texnologiyadir.
TD-CDMA,
an acronym for Time-
division-Code division multiple
access, is a channel access method
based on using spread spectrum
multiple access (CDMA) across
multiple time slots (TDMA).
WCDMA
