Google to monitor unused white space across the US, take us one step closer to spectrum sharing
One of the biggest hold-ups in the global deployment of LTE and long-range WiFi is a lack of available spectrum. Even when a particular frequency is free and usable for mobile broadband, it's often officially reserved for some other purpose. Google's charitable wing, Google.org, has long claimed that as much as 6 MHz of white space kept aside for TV channels in the US is actually untapped, and now it's going to get a chance to prove the point. The FCC has just granted it a 45-day window in which to run a trial public database (linked below) to keep track of exactly which bits of spectrum are free in which parts of the country. If all goes well, Google should find itself among up to ten other organizations that are allowed to supervise spectrum sharing -- in other words, allowing mobile devices to temporarily exploit available TV spectrum that isn't being used by the primary holder. Google's ultimate aim, we're told, is simply to "improve connectivity" at a global level. As to whether the other nine names on the FCC's list -- like Microsoft and Ericsson-owned Telcordia -- are equally altruistic, we have absolutely no idea.
European Commission pushes for spectrum sharing, sees 5GHz WiFi getting a lift
The European Commission is well aware that we need spectrum. Rather than make everyone fight for their piece, though, the agency wants us to hug it out. It's proposing a spectrum change that would bring in "much more dynamic sharing" of both licensed and unlicensed radio frequencies. While nothing's definite at this point, the EC's Digital Agenda representative Ryan Heath mentions that the move could give more capacity to WiFi in the unlicensed 5GHz space -- no doubt a relief for anyone who's dealt with an overwhelmed public hotspot. That's not to say that carriers won't benefit. Officials want to provide perks by offering "guaranteed rights" to providers and anyone else that has to share licensed airwaves with others. The sharing initiative is a long distance away from having an impact given that the Commission is calling for help from the European Council and Parliament just to get started, but it could be an important step towards harmony in a land where unoccupied airwaves are rare.
US and Mexico strike public safety spectrum deal along national borders
The FCC announced today that Chairman Julius Genachowski has entered into an agreement with Mexico's telecommunications officials to create a new spectrum sharing scheme along the nation's borders. The move will normalize 800MHz and 1900MHz spectrum use within 68 miles of the common border, and is primarily intended to reduce interference and allow for reliable public safety communications in the region. Further rollout of commercial services is also central to the pact, as Sprint has been authorized to deploy its CDMA service in the 1900MHz spectrum along the border. The move is hardly a free gift, however, as Sprint had previously surrendered a share of its 800MHz holdings to pave way for the agreement. A bi-national task force will oversee the adjustment process, and both nations have agreed to discuss future spectrum coordination along the border in future meetings. Proof that cooperation isn't completely dead, folks. To gain a greater understanding of where both nations are headed, just hop the break for the announcement.
