Wi-Fi Direct Gets Real With Product Certification
CWmike writes "Wi-Fi Direct officially became a concrete technology today, with several new laptop components certified by the Wi-Fi Alliance. That threshold was reached before most people even understand what Wi-Fi Direct is, reports Matt Hamblen. Wi-Fi Direct is a new technology designed to allow peer-to-peer Wi-Fi connections between devices like smartphones and cameras without a traditional Wi-Fi network or the need for Wi-Fi access points. This means that a camera with Wi-Fi Direct installed could communicate via Wi-Fi to a digital picture frame or printer, uploading picture data over the same range of existing Wi-Fi, about 200 yards at speeds of up to 250Mbit/sec, said Wi-Fi Alliance CEO Edgar Figueroa. 'Imagine if two people were on a train and wanted to play a game in real time on their separate handhelds but had no cellular or Wi-Fi hot spot. They still could play with Wi-Fi Direct,' he said."
I've been able to have two Wifi laptops communicate in an ad-hoc network forever, so how is this really different?
bluetooth is GREAT for remote controls... first of all you don't need line of sight to the receiver, and the latency and responsiveness are at least 5 times as good as IR... i recently got the bluetooth slide remote for tivo and didn't even realize how slow my IR remote was to respond until things started working like they should with bluetooth.
This is very true. I have a bluetooth mouse with the original battery that came with it inside, and it's still working after 2 years of use. Device with low bandwidth and little mobility requirements are very good with bluetooth right now.
