What is CDMA technology?

CDMA - Technology. 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 band used in CDMA?

The band used in CDMA is 824 MHz to 894 MHz (50 MHz + 20 MHz separation). Frequency channel is divided into code channels. 1.25 MHz of FDMA channel is divided into 64 code channels. CDMA is a spread spectrum technique. Each data bit is spread by a code sequence. This means, energy per bit is also increased. This means that we get a gain of this.

What are the techniques used in CDMA?

Techniques generally used are direct sequence spread spectrum modulation (DS-CDMA), frequency hopping or mixed CDMA detection (JDCDMA). Here, a signal is generated which extends over a wide bandwidth. A code called spreading code is used to perform this action.

Who uses CDMA and GSM?

In the US, Verizon, US Cellular, and the old Sprint network (now owned by T-Mobile) use CDMA. AT&T and T-Mobile use GSM. Most of the rest of the world uses GSM. The global spread of GSM came about because in 1987, Europe mandated the technology by law, and because GSM comes from an industry consortium.
