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

QCT provides manufacturers with the hardware, software, tools and training, and technical support that lead to the smallest, fastest, most affordable, and feature-rich CDMA digital wireless products in the world. Along with the expansion of customers there was also a concern about the availability of bandwidth as the radio frequency became overcrowded. As the pioneer of CDMA, the foundation for 3G communications, QUALCOMM continues to lead the industry in the development of voice, data, and wireless Internet products and solutions. QCT’s chipsets and system software enable such diverse consumer devices as mobile handsets, personal digital assistants, safety location devices and wireless Internet connections worldwide. A number of American firms also developed CDMA, (Code Division Multiple Access Technology), technology. As the world's leading developer and supplier of CDMA chipsets, and solutions, QCT has shipped more than 500 million chips to CDMA manufacturers around the world. This enables the network to carry a higher capacity of calls of a higher reception quality and enables the user access to a wider number of advanced features, such as Personal Digital Assistants, (PDA's), mobile faxing and wireless e-mail. This technology has not caught on as much as TDMA, despite the fact it has 10-20 times the capacity of analogue technology.
The new digital networks use their allotted radio frequency's more efficiently than analogue and sound is transmitted by computer code rather than by waves.
There have been commercial consequences concerning these new technologies. has developed and commercialized innovative communications solutions since its founding in 1985.
