Once again we are faced with a new technology that is being hyped as the “next big thing”. As the hype cycle sets expectations higher and higher, the disillusionment when reality sets in will only be deeper and deeper. Just ask your local Bluetooth vendor. UWB is an exciting new technology with some very impressive capabilities. But claims of 500Mbps and hundred meter ranges for five dollars need to be looked at with a healthy dose of skepticism. Realistic expectations over the next year or so are closer to 100-200Mbps over 10 meters with a bill of materials approaching $30.
