Where is CDMA used?

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.

What is the meaning of CDMA?

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.

How does CDMA technology work?

CDMA uses spread spectrum technology to transmit data. This technology permits several phones to send and receive through a single channel. Each part of these separate conversations is labeled with a specific digital code. The carriers that use CDMA technology include Sprint, Verizon, Alltel, and NEXTEL.

How CDMA works in wireless LAN?

How CDMA Works. CDMA uses a “spread-spectrum” technique whereby electromagnetic energy is spread to allow for a signal with a wider bandwidth. This approach allows several people on different cell phones to be “multiplexed” over the same channel to share a bandwidth of frequencies.
