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 phone systems in the 800 megahertz (MHz) and 1.9 gigahertz (GHz) bands.

The IS-95 CDMA system operates in the same frequency band as the AMPS using frequency division duplex (FDD) with 25 MHz in each direction. * The uplink (mobile to base station) and downlink (base station to mobile) bands use frequencies from 869 to 894 MHz and from 824 to 849 MHz, respectively.
Read moreWhat CDMA used for?
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.
Read moreWhat is the RF bandwidth required for CDMA IS-95 standard?
Similar to most other digital vehicular cellular systems, IS95 uses speech coding at about 9.6 kbit/s .
Read moreWhat type of receiver is used in CDMA?
What is Rake Receiver ? CDMA system uses a signal fast chip rate for spreading spectrum and it has a high time resolution. For this reason, CDMA is able to recognize by decomposing each of the path to reach with the time difference.
Read moreWhat is CDMA how it works?
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.
Read moreHow does CDMA allow channel reuse?
The IS-95 CDMA and CDMA radio channels use coded channels that are uniquely assigned to each user . This allows many users to operate on the same frequency. This also allows frequencies to be reused in every cell site and sectors within a cell site.
