13. What’s CDMA?
 CDMA (Code-Division Multiple Access)
 CDMA is a form of multiplexing, which allows numerous signals
to occupy a single transmission channel, optimizing the use of
available bandwidth. The technology is used in ultra-high-
frequency (UHF) systems in the 800-MHZ and 1.9-GHz bands.
 Researchers started even 1950.
 IS-95 The narrow band CDMA mobile network has been
standardized in 1993.
 CDMA wideband CDMA system Such as CDMA2000 in US and
Europe and WCDMA developed in 1990 and still ongoing
