Many of us have often wanted to have a satellite phone, in times when our Wi-Fi speeds are terrible or other connectivity options are down. Globalstar may make this possible with its Sat-Fi, a service that can turn any Wi-Fi device into a satellite phone.

Google has made a rather generous gift of $600,000, spending the money to bring absolutely free Wi-Fi to some 31 locations in San Francisco.

University of Washington researchers have shown it's possible to leverage Wi-Fi signals around us to detect specific movements without needing sensors on the human body or cameras. Using a Wi-Fi router and a few wireless devices in the living room, users could control their electronic devices from any room in the home with a simple gesture!
