InterDigital Communications Corporation has been a pioneer in wireless telecommunications technology for more than 30 years. The publicly traded company is based in King of Prussia, Pennsylvania, a suburb of Philadelphia. InterDigital's inventions, technology, and systems can be found in cell phones, personal digital assistants (PDAs), mobile computing devices, and other wireless devices—as well as base stations and other infrastructure equipment. A leader in the development of the first two generations of wireless technology, InterDigital is now concentrating on the development of intellectual property for the third generation of wireless communications, or 3G, and the WCDMA (wideband code division multiple access) airinterface protocol. The company focused on two different ways to achieve two-way communication, known as duplexing. Frequency Division Duplexing (FDD) splits the channels into separate frequencies. Time Division Duplexing (TDD) creates time slots to split a single channel. In addition to its King of Prussia facility, InterDigital also maintains operations in Canada, the United Kingdom, and Germany.
