Samsung has introduced a tiny W-USB (wireless USB) chip for mobile devices. Claimed to transfer data at up to 120Mbps, the "S3CR650B" uses an ARM9 core, and provides wireless and SD/MMC interfaces, flash memory, and a USB 2.0 interface, the company says.

Samsung's S3CR650B, said to employ a ARM9 core for its baseband processor, measures just 8mm x 8mm, with a claimed power consumption of just 300mW. The company says the device provides transfer speeds of up to 480Mbps -- comparable to wired USB 2.0 -- though it concedes that this drops to 120MBps when "conventional payload overhead" is taken into account.
