''The key point is that UWB was designed with these challenges in mind. Its short pulses are such that multi-path interference will not cancel out the primary signal. These short pulses can also be measured much more precisely than narrowband signals, making distance and location measurement much more accurate. In practice, UWB can measure location to within 5-10cm, an order of magnitude better than Wi-Fi and Bluetooth based systems. And UWB devices can communicate in a mesh network configuration, in which each device can talk with many other devices.

As we move into 2015, as technology is becoming more and more personal, UWB radio will enable all of our connected “things” to talk to each other and track their locations. With UWB technology, the connected things in our pockets and around our homes and offices can communicate with each other without interference, and can track location and distance precisely enough to offer accurate location awareness. So your smartphone can lead you directly to your lost keys, your home entertainment system will know who is in the room and who is in the room next door, your washing machine will know precisely which screen or display device you’re near, and your lights will know when you’re in the room and won’t mistakenly turn off.''

''However, ZigBee and UWB are emerging technologies with tremendous market potential, mainly due to long battery life, enhanced accuracy and high location precision. ''

''In other aspects of the invention, the social statistics sensors can include an Ultra Wideband sensor which can provide ranging data, such as occurs with radar. In this manner, the ranging data could provide a 3D image of the room in which the mobile device 100 is located, and/or provide simple room size and obstacle location measurements. The use of the ranging data would be usable in the social signature in aspects of the invention. By way of example, the ranging data could be usable in the social signature when combined with the map location detected from the mapping processor the location on a map, thereby allowing a social template to be constructed to provide information based both upon map location and a location relative to walls of a specific room in that location.''

Thnx plank, I'd read most PN BID stuff before but overlooked freescale, they were big into UWB and still see a future in it; hope this will help them see a future with us. They'r big in CA - I'd have go dig up the things but they're a front-runner; as we should be, soon.
