Cdma & gsm meaning
Did you know?
WebCDMA (Code-Division Multiple Access) refers to any of several protocols used in second-generation (2G) and third-generation (3G) wireless communications. As the term implies, CDMA is a form of multiplexing, which allows numerous signals to occupy a single transmission channel, optimizing the use of available bandwidth. WebIf you connect a phone that is GSM only to a CDMA network then it will only work on 4G or 5G, not 3G or 2G. CDMA-less mode forces the phone to be always on 4G or 5G, which allows GSM only devices to work with CDMA networks. CDMA-less = 4G or 5G only. CDMA = 2G, 3G, 4G, or 5G. 1 rohitvarma1986 • 3 yr. ago Thanks for sharing !! Good knowledge.
