Princeton's tiny Bluetooth adapter with big 300-foot range

From Engadget -




Princeton's tiny 4.5 x 23 x 14-mm USB Bluetooth PTM-UBT4 adapter has a hearty 100-meter range. And because it's a Bluetooth 2.0+EDR it has a data rate of up to 3Mbps. It will hit Japan and beyond for ¥2,980 (roughly USD28) later this month.
