Not only can you now improve your vision above 20/20, but new tech called ultra-wideband will soon allow the ordinary average Joe to detect underground objects and ?see? through walls. Are you thinking what we’re thinking?Ultra-wideband uses millions of narrow pulses each second to get an accurate reading of location and distance, opening the door for new applications in radar tracking, precise positioning andwireless communications. The possibilities vary from short-range computer networking for homes to devices that determine the location of golfers on a course. What regulators like even better is that ultra-wideband devicescan work within frequencies already allocated for other radioservices - helping to maximize this dwindling resource. Time Domain Corp., an Alabama based company,. has already developed some ultra-wideband products which allow law enforcement officials to detect motions through surfaces such as walls. Members of a local county rescue squad were able to see people still breathing under 12 feet of rubble using the devices after a building collapse, Petroff said. Newer versions to be introduced in the fall will provide even clearer silhouettes. Petroff says the chief benefit of ultra-wideband ?is the ability to create entirely new products that don’t yet exist and entirely new industries.’ Can it see through summer dresses, though? That?s what the buying public want to know. Whatever, the US Federal Communications Commission believes the technology is so promising that the agency has proposed allowing it to be used on an unlicensed basis. `Because of improvements in technology, it is now time to take a look at making this service available to consumers, businesses and public safety providers,’ said FCC Chairman William Kennard.
