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.<\/p>\n\n\n\n<p>CDMA employs analog-to-digital conversion (ADC) in combination with spread spectrum technology. Audio input is first digitized into binary elements. The frequency of the transmitted signal is then made to vary according to a defined pattern (code), so it can be intercepted only by a receiver whose frequency response is programmed with the same code, so it follows exactly along with the transmitter frequency. There are trillions of possible frequency-sequencing codes, which enhances privacy and makes cloning difficult.<\/p>\n\n\n\n<p>Information Credits: <a href=\"https:\/\/searchnetworking.techtarget.com\/definition\/CDMA-Code-Division-Multiple-Access\" target=\"_blank\" rel=\"noreferrer noopener\" aria-label=\"Techcredit (opens in a new tab)\">Techcredit<\/a><\/p>\n","protected":false},"excerpt":{"rendered":"<p>CDMA (Code-Division Multiple Access) refers to any of several protocols used in second-generation (2G) and third-generation (3G) wireless communications.
