Definition[]
Code Division Multiple Access (CDMA) is any of several protocols used in so-called second-generation (2G) and third-generation (3G) wireless communications. CDMA is a form of multiplexing, which allows numerous signals to occupy a single transmission channel, optimizing the use of available bandwidth.
Overview[]
The technology is used in ultra-high-frequency (UHF) cellular telephone systems in the 800-MHz and 1.9-GHz bands.
