How are cell phones related to technology?

Answer 1

Cell Phones are probably the most technologically sophisticated things we use in everyday life (the other major candidate being Computers and the internet). Cell Phones depend heavily on at least the following major areas of Technology: * Computers (used to control every aspect of the network, including routing calls, billing, spectrum allocation, etc.) * Radio (including modulators, high and low power transmitters, highly sensitive low power receivers, digital demodulators, and issues of spectrum allocation and propagation.) * Electronic Speech Processing (speech encoders and decoders that compress the data rate required to handle speech and increase network capacity.) * Wireless Technology (GSM Technology to bring the Internet to cell phones, and Bluetooth to link phones to headsets.) * Digital Cameras and LCD Displays (highly sophisticated in their own right.) * Fiber Optics (often used for trunking data to cell phone base stations.) * Circuit Miniaturization (Integrated Circuits, surface mount technology, and other developments in this area make modern small cell phones possible.) * Batteries (sophisticated miniature, high capacity batteries make modern small cell phones with long talk times and ranges possible.) * And last, but not least, the entire preexisting terrestrial telephone network!
