The major difference between this and WiFi (aside from the range) is that unlike WiFi -- which operates in unlicensed spectrum -- FlashLinq requires licensed 5MHz TDD spectrum.
Basically, this wireless technology allows FlashLinq-enabled devices to sense up to 4, 000 other FlashLinq devices within a radius of up to 1km, which puts things like WiFi and Bluetooth to shame.
The company is still hammering out which chips will ship with FlashLinq support, and it'll be waiting for results from its SK Telecom trial (which starts in April) before committing to a commercialization date.
FlashLinq-enabled televisions, laptops, in-car infotainment systems, etc. could all be used to create a discoverable network of interactive goodness, but of course, it's hard to say how much success Qualcomm will have in a world already loaded down with connectivity options.
