Qualcomm
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 tomorrow's 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&T (American Telephone and Telegraph), in it's Bell
Unfortunately, analogue networks are limited, in that they suffer from severe capacity constraints. There are reception and interference problems, they are also less secure to prying ears and most importantly from a user point of view, coverage is restricted to the UK. Along with the expansion of customers there was also a concern about the availability of bandwidth as the radio frequency became overcrowded. Such inefficiencies obviously led to the demand for a new and improved alternative, so along came digital technology. 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 countries such as Italy, Spain, Austria and Eire. QUALCOMM CDMA Technologies is a recognized industry leader in development and supply of innovative, high-quality, cost-effective wireless microelectronics solutions. Qualcomm believes that they succeed because our customers succeed, and we use this belief to gu
