Qualcomm's first products and services include OmniTRACS satellite positioning and messaging services, widely used by long-distance trucking companies, and radio digital communications technology specializing in integrated circuits, such as the Viterbi decoder.
Qualcomm developed a digital cellular communications technology based on CDMA technology, the first version of which was standardized as the IS-95 standard. New products developed later used the same theme, including IS-2000 and 1x-EVDO. Qualcomm developed and sold CDMA mobile phones and CDMA base station equipment. It is currently one of the twenty largest semiconductor manufacturers in the world.
Qualcomm has always focused on innovation, and the company continues to invest a lot of resources to ensure the company's technological leadership in the field of wireless communications. Qualcomm has developed and maintained many important patents around the world. This includes patents related to standards in the fields of 3G and 4G wireless communication technology.
These patents are very valuable.
Extended information:
Currently, Qualcomm has sold its base station business and mobile phone R&D business to Ericsson and Kyocera respectively, and is now mainly engaged in the development, radio technology licensing and sale of their ASICs .
Qualcomm's other businesses include developing Globalstar satellite systems (a joint venture with Laura Space and Communications) and a joint venture in digital cinema and color printing. He also developed the BREW (Binary Runtime Environment for Wireless) mobile platform. He also maintained and sold the Eudora email program.
OmniTRACS is a trunking communications technology designed for the transportation market. As of the summer of 2005, 567,000 units of transportation partners were deployed on 4 continents.
Qualcomm designs various ARM architecture CDMA chips for mobile site modems (MSM), baseband radio chips and power processing chips. These chipsets are sold to mobile phone manufacturers such as Kyocera, Motorola, HTC, and Samsung for integration into CDMA multiplex mobile phones.
Qualcomm used to design, maintain and sell the email software Eudora.
Qualcomm is also developing a cellular/data system, Q-Chat, for the merged Sprint-Nextel company to replace Nextel's existing iDEN system.
