Microsoft Mixes Up White Space Fix
A team of researchers from Microsoft and Harvard University have created a breakthrough technology that should make the use of white space spectrum for wireless broadband possible. White spaces are the unlicensed spectrum that resides between analog TV channels. The FCC has placed strict rules about the use of white space, and the nearby TV channels cannot be interfered with. In order to solve this engineering challenge, Microsoft created an "adaptive spectrum assignment algorithm". The algorithm constantly measures the frequencies being used and works in concert with other gadgets to find frequencies that aren't being used. If the devices discover that spectrum is already being used, they switch to a back-up channel. Microsoft was able to create an entire network with this methodology. Microsoft calls the technology "White-Fi", and indeed, it behaves similar to Wi-Fi in some respects. White-Fi won't have the bandwidth of WiMax or LTE and speed will depend on what frequencies are being used in any given region. Because the spectrum is unlicensed and doesn't need to be paid for, the networks using it should be less expensive to build and run.
Essential Says Black PH-1 Shipping Within A Week, White PH-1 Not Ready Yet
Essential Products today began emailing customers who preordered the PH-1 smartphone with news of the device's imminent arrival. "Great news, your phone has been built!
Qualcomm Says First MulteFire Connection a Success
Qualcomm today said it made the world's first over-the-air connection using MulteFire. MulteFire is a new, more advanced version of LTE that uses a technology called listen-before-talk (LBT) to operate on unlicensed spectrum.
Google Photos Update Adds Auto White Balance Correction
Google says a new version of its Google Photos app introduces several new editing tools for improving photographs. The Google Photos editor already automatically corrects exposure and saturation, but will now also automatically correct white balance.
T-Mobile Rolling Out LTE-U
T-Mobile today said it is beginning to upgrade its 4G network with LTE-U this spring. LTE-U allows LTE to operate on the unlicensed spectrum in the 5 GHz band, which is typically reserved for WiFi.
AT&T Wants LTE-U Opponents to Agree to Play Fair
Joan Marsh, AT&T's vice president of federal and regulatory affairs, today prosed that the FCC use existing rules to help organizations on opposite sides of the LTE-U debate find some middle ground. LTE-U is the use of LTE services over unlicensed spectrum, or WiFi frequencies.
