Code Division Multiple Access (CDMA) is a sort of multiplexing that facilitates various signals to occupy a single transmission channel. It optimizes the use of available bandwidth. The technology is commonly used in ultra-high-frequency (UHF) cellular telephone systems , bands ranging between the 800-MHz and 1.9-GHz.

The Reverse CDMA Channel consists of 2 42-1 logical channels . One of these logical channel is permanently and uniquely associated with each mobile station. That logical channel is used by the mobile whenever it passes traffic.
Read moreWhat is CDMA explain in detail?
CDMA (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.
