| CDMA (code-division multiple access) refers to any of
several protocols used in so-called 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. The technology is used in ultra-high-frequency
(UHF) cellular telephone systems in the 800-MHz and 1.9-GHz bands. |
