The Irvin M. Jacobs Qualcomm Hall at the company's San Diego headquarters is the largest building at the facility. Qualcomm actually owns several buildings in the San Diego area and is among the city's largest property owners.
Qualcomm proudly displays a wall of its many patents, which spans two floors (and isn't the complete set). The company heavily relies on its patents for licensing revenue, which allows it to continue funding its research and development projects.
OmniTRACS was one of the first truck fleet management systems, which Qualcomm sold as a way to generate funding for its research. Eventually, Qualcomm switched to the licensing business to generate more cash.
Qualcomm has developed a technology called AllJoyn that allows for devices to talk to each other locally, rather than constantly pinging the network. That's useful for things like multiplayer online games. By communicating locally, the devices can enable a faster connection between devices (and a better gaming experience). Qualcomm showed off the capabilities of AllJoyn through two HTC Flyers and Pac-Man Racing.
Using AllJoyn technology, Qualcomm developed a prototype app that allows multiple phones to share songs, creating a communal jukebox ideal for the beach or in the car. Any phone can select the song, adjust the volume, or add a playlist.
The S4 SnapDragon processor from Qualcomm is a dual-core engine that is the first to integrate a 2G, 3G and 4G LTE radio. The company has a factory on the grounds that builds mobile development platforms (seen here) that carry the chip. Qualcomm sends them to handset manufacturers, carriers and app developers to get them using the chip early. The first products with an S4 chip will come out next year.
