  • Here is a graphic of the BREW architecture. As you can see, it sits on the chip system software and handset user interface. Last year, Qualcomm shipped over 50 Million chipsets. This year, we are predicting shipments of 90 Million CDMA handsets, of which Qualcomm chipsets power a very large percentage. Every one of those chipsets runs our system software. And BREW is integrated on top of that system software. This makes BREW the most widely available plaftform for wireless application development at launch. Applications, from messaging and games to personal information programs and position location software, sit on top of BREW. The BREW API, or applications programming interface, provides access to services built into the Chip software and phone functions through a standard set of BREW program calls. In addition, the services available on the phone can be extended via downloaded components. These can be discovered and accessed by applications. To support existing and new paradigms, BREW supports easy integration of multiple browsers and even Java apps. For the device manufacturer, there are a number of benefits to adopting BREW. They can drive additional embedded functions for higher margin; decrease development cost of integration. They can run new applications without having to to partner with every app developer. In addition, the capabilities of a given device can be done late in the manufacturing cycle, even after the phone has left the factory, to add carrier-specific UIs, localize the product for new markets, to add enhanced features, etc. Speaking as someone who has run a handset business, this is a significant cost savings.
