Qualcomm essays

Qualcomm essays Code Division Multiple Access (CDMA) is the ultimate in inside communications technology. It is fastest growing wireless technology. CDMA already has tens of millions of users throughout the world. The reasons for this are simple. CDMA supports current voice and data needs while providing a quick, cost-efficient evolutionary path to tomorrows systems. CDMA has greater voice quality and call clarity than other technologies because it filters out background noise, cross-talk and interference. CDMA has fewer dropped calls because it increases voice and date transmission reliability. CDMA has greater spectral efficiency because it packs more transmissions into the same space, resulting in fewer cell sites, which lowers operators' costs. It also has increased capacity, enhanced privacy, and improved coverage. Since the first cellular mobile telephone networks opened for business in the early 1980's, growth in numbers of subscribers has consistently exceeded even the most optimistic forecasts. Even in the most advanced markets, this growth shows little sign of abating, and meanwhile, new markets are accelerating rapidly. Cellular phone technology was developed by AT The first mobile cellular network operators in the UK, (Cellnet and Vodaphone), began using analogue technology for their first networks because it was the only available and prevailing technology of that time. Analogue technology is based upon the transmission of sound by way of radio waves through an Analogue Mobile Phone System (AMPS), and conforms to the relevant Total Access Communication System (TACS), standards of operation in count ...
