CDMA stands for Code Division Multiple Access. It is wideband spread spectrum technology by which multiple conversations are spread over a wide segment of cellular broadcast system. CDMA is also known as spread spectrum. In this technology-
1. Every data is assigned a unique code to distinguish from multiple calls.
2. Multiple calls can be transmit simultaneously over a same broadcast spectrum.
3. At receiving end, if the receiving device has right code than it can pick its conversations from all others.
It is used in military satellite system. It is secure and uses more spectrum efficiencies.
