Alereon's CEO posts love letter to ultrawideband: The FCC approval for the use of UWB technology in the US was approved five years ago on this day of love. Alereon head Eric Broockman gives a few noogies to Freescale--which he says is out of the UWB business altogether, something rumored for months now--and then blows kisses to the crowd. UWB in the form of Wireless USB is imminent. Yes, I know it's been "imminent" for anywhere from two to four years. But there are actual working chips, actual working prototypes, and products lurching toward market.
