Ultra Wideband (UWB) – its civilian use has been talked about for a while (the military been using it for about twenty years) and now the US FCC has revised some of its rules to enable be used commercially.
Its major advantages are low-cost implementations and low-power consumption – leading to one example of it use being to tagging goods to track them on a dock-side or in a ship. Civilian uses are currently less clear but with single devices peaking at over 50Mbps over 10m, distribution of high-quality video over short distance would be possible.
