CDMA is a digital technology for transmitting data. It is a general technology utilized through various standards.
CDMA has no limit on capacity but the base station will only connect users upon determining that the call quality would fall bellow a predetermined limit.
The term is often used to refer to one specific family of technologies - IS-95 (often referred to cdmaOne) and CDMA2000. Networks using this technology operate in the 800 and 1900 MHz frequency bands and are primarily used in the Americas and Asia.
Wideband CDMA is a third-generation (3G) wireless standard which allows use of both voice and data and offers data speeds of up to 384 Kbps.
The frequency bands for WCDMA are as follows: Europe and Asia - 2100MHz, North America - 1900MHz and 850MHz.
WCDMA is also called UMTS and the two terms have become interchangeable.
Some parts of the WCDMA are based on GSM technology and the networks are designed to integrate the GSM networks at some levels.
UMTS or the Universal Mobile Telecommunications System is a third generation wireless network technology which allows speeds of up to 2Mbps.
UMTS is based on the WCDMA technology, which is why these terms have become interchangeable.
GSM (Global System for Mobile Communications, originally Groupe Spécial Mobile), is a standard developed by the European Telecommunications Standards Institute (ETSI) to describe protocols for second-generation (2G) digital cellular networks used by mobile phones, first deployed in Finland in July 1992.
