Today things are a bit more clear as to why Intel abandoned its own Ultra Wide-Band efforts
in favor of off-the-shelf solutions: Samsung just announced its ultra-fast Wireless USB chipset. Samsung's tiny 8 x 8-mm (0.31 x 0.31-inch) chip operates in the traditional 3.1 ~ 10.6GHz Certified Wireless USB space and delivers a relatively blistering 120Mbps data transfer rate (measured, not
theoretical) compared to the 50Mbps achieved by current solutions -- that's a single ripped 700MB film transferred in about a minute from a range of about 3 meters. It also features 128-bit AES encryption and other security mechanisms meant to safeguard your data during transmission. The SystemOnChip design consumes 300mW of power and brings a built-in ARM core, UWB (ultra wide-band) physical layer, and memory controller while interfacing with SD cards, MMC, NAND, and USB 2.0 without any additional circuitry. In other words, expect to see Samsung's Wireless USB in digital cameras, MP3 player, speakers and more when these chips hit mass production in Q2.
It's worth noting that Samsung is a member of the Wireless USB Promoter Group that pushes the "Certified Wireless USB" standard. However, with Wireless USB start-up WiQuest out of the picture
and zero references made to the standard or use of the group's logo, this might very well be a proprietary grab at the short-range wireless space that has received very little interest from vendors to date. We'll find out more more when Samsung presents its WUSB solution for the first time at Mobile World Congress next week.
