Qualcomm's first products and services included the Omnitracs satellite locating and messaging service, widely used by long-haul trucking companies, and specialized integrated circuits for digital radio communications such as a Viterbi decoder.
Qualcomm developed a digital cellular telephony technology based on CDMA; the first version was standardized as IS-95. It has since developed newer variations on the same theme, including IS-2000 and 1x-EVDO. It formerly manufactured both CDMA cell phones and CDMA base station equipment.
Qualcomm sold its base station business to Ericsson and its cell phone manufacturing to Kyocera, and now focuses on developing and licensing wireless technologies and selling ASICs that implement them.
Other Qualcomm projects include the development of the Globalstar satellite system (a joint venture with Loral) and a joint venture in digital cinema with Technicolor. It also maintains and sells the Eudora email program.
