Why CDMA?
Worldwide demand for wireless communication is increasing. There is increase in demand for 3G technology, wireless email, web, wireless data transmission, GPS, video and audio streaming and TV broadcasting and other wireless benefits. Here is the role of CDMA. CDMA technology can provide excellent wireless services for voice and data transmission.
CDMA uses “spread spectrum" technology and allows more than one user to occupy the same time and frequency allocations in a given band/space. CDMA assigns unique codes to each communication to differentiate it from others in the same spectrum. CDMA enables many more people to share the airwaves at the same time than other alternative technologies.
