The Bsquare-supplied driver is based on the company's
SDIO Hx stack, and supports throughput rates of over 10 Mbps. Bsquare claims that the "high performance" stack enables Windows Mobile devices to download songs and other multimedia files from the Internet, via a wireless access point, in a sixth the time required by other Windows Mobile WiFi stacks.
NXP's WiFi controller is contained in a 10 x 15 x 1.3 mm package. The "SiP" (system-in-package) device integrates a 90nm CMOS 802.11g baseband/MAC along with a silicon-germanium BiCMOS radio transceiver. Additionally, a built-in ARM7 processor offloads WLAN-related tasks from the host processor.

According to Paul Marino, NXP's VP of Business Line Connectivity, the combination of Bsquare's SDIO client driver and NXP's "leading low-power WLAN solutions" results in "best-in-class WLAN performance" on client devices running Windows Mobile. "Our solution enables our customers to deliver rich and satisfying real-time wireless multimedia experiences on mobile and portable consumer devices, like SmartPhones and Portable Media Players, without sacrificing battery life," he added.
NXP plans to demonstrate the BGW211 running the Bsquare SDIO Hx Windows Mobile client driver at the 3GSM World Congress in Barcelona next week.
