“In advance, yes — you’re right, it’s impossible. But nonetheless, we have ten radios all working at the same frequency, all at the Shannon limit… and there’s no interference.” You may not fully grok the significance of that statement, but anyone heavily involved in solving the wireless bandwidth crisis is probably dropjawed. For a little background, there’s a perceived limit in wireless known as Shannon’s Law, which largely explains why no one can watch a YouTube clip on their EVO at Michigan Stadium. For whatever reason, it’s been assumed that this law was fundamentally unbreakable, but it looks as if an unlikely member of society may have just overrode expectations. OnLive’s CEO Steve Perlman recently revealed a breakthrough from Rearden Companies — in short, they’ve figured out a workaround, and in testing, it’s doing things like “removing dead zones” altogether. His slide, shown during a presentation at Columbia, notes that the implications here are “profound,” and we couldn’t agree more. Do yourself a solid and hit play in the video below the break — we’ve fast-forwarded to where this section begins.

June 29th, 2011 admin Smirking as you pull down borderline-criminal speeds on your Droid Charge ? Ericsson’s doing you (at least) one better. The Swedish company is pushing out-of-this-stratosphere speeds to its testing van using upcoming LTE-Advanced technology; it managed to hit download speeds that exceed our paltry LTE limit by a factor of ten — that’s 1Gbps , folks. Not only is Ericsson cranking up the speed, it’s also endeavoring to make the new network more efficient by offering 8×8 MIMO (Multiple-Input, Multiple-Output) functionality, which enables data to be retrieved and sent faster regardless of network congestion. Of course, these test results are taking advantage of 60MHz available bandwidth, as opposed to the global max of 20MHz and the US standard of 10 . If we’d like to see speeds of such magnitude, we’ll have to come across more spectrum somewhere, and soon; Ericsson hopes to have the first phases of LTE-Advanced ready to bump up our network speeds by 2013. At that point, ” faux G ” will take on a whole new meaning, won’t it? Full PR and video after the break.

June 21st, 2011 jedwan LightSquared may have steadfastly insisted otherwise, but recent tests showing that its wholesale 4G LTE network interferes with GPS have been getting tough for it to ignore, and it turns out the company has been quietly working on a backup plan. In addition to fessing up that one of the 10MHz blocks used by its network does indeed interfere with many GPS receivers, LightSquared has also now announced a two-fold “solution” to the problem. That will involve it using only a lower block of the 10MHz spectrum that it says doesn’t interfere with GPS (with a few “limited” exceptions), and a new agreement with Inmarsat that LightSquared says will let it “accelerate the schedule” to begin using the alternative block of spectrum. Those new measures, LightSquared says, will let it roll out its network in accordance with its original business plan, and give it enough spectrum to serve its customers for the “next several years.” What happens after that is a bit less clear, but LightSquared says it believes its network can “live harmoniously, side-by-side, with GPS users,” and that “enlightened and responsible spectrum management will give the American public the best of both worlds.” The company’s full press release is after the break.

May 3rd, 2011 jedwan We were admittedly a bit skeptical when Meizu CEO Jack Wong first starting talking up the M9 Android handset — in fact, the word “vaporware” may have been tossed around a bit. The exec proved our caution unfounded, however, delivering the phone into the hands of China’s incredibly enthusiastic smartphone buyers . Then Wong briefly turned his attention away from the handset to give us a taste of its successor , but now the he’s back — with a downloadable Gingerbread update for his beloved M9. Results of the upgrade have been mixed at best, with users reporting some minor power and display problems on one end of the spectrum and improved audio the other. If you must download, check out the source link below — just don’t say we didn’t warn you.

FCC: white space devices won’t require spectrum sensing modules
September 29th, 2010 admin Phew. For a moment few years there , we thought any device set up to operate on these so-called white spaces — which have been vacated following the analog-to-digital TV transition — would be forced to use spectrum sensing modules in order to ensure that no TV station was operating in areas in which it wanted to. Based on the FCC’s Second Memorandum Opinion and Order, which was just published a few days back, it looks as if forthcoming white space devices will not be required to ping databases in order to make absolutely sure that it won’t interfere with TV stations. That’s the long and short of it, which is fantastic ( if not expected ) news for device makers and anyone who despises red tape, but Ars Technica has taken an in-depth look at why the Commission made such a call. Indeed, the FCC’s 2008 Order mandated that white space gadgets check in beforehand in order to “protect TV signals from interference.” Essentially, the call that nixed this addition was the fact that this security ring would inadvertently provide “many wireless microphones systems that go to unlicensed use” — things like wireless systems at churches, football games, concerts, etc. As with anything FCC -related, it’s a long and wordy explanation, but those interested in the finer details are just one click away from the nitty-gritty.

July 23rd, 2010 admin You know that ” National Broadband Plan ” that the world keeps yapping about? Sprint’s down with it, and has been since before it ever existed, apparently. Based on a glowing press release outed this week by the carrier, it has just wrapped up a five year initiative to free 35MHz of highly valuable spectrum needed for future broadband expansion. After spending a cool $750 million from 2005 to 2010, the company has now cleared 35MHz of broadcast auxiliary service (BAS) spectrum across the country, though there’s obviously some ways to go before Obama has 500MHz of cleared spectrum at his disposal. As it stands, Sprint has transitioned the broadcast auxiliary services to a new, more efficient spectrum plan in the 2GHz frequency band, and while the exact hows and whens have yet to be laid out, we’re hearing that this could provide access to “faster, cheaper broadband services” in the future. Huzzah?

May 27th, 2010 jedwan We’d not-so-secretly hoped that carriers would be looking to dispense with those troublesome 5GB caps on so-called “unlimited” 3G data plans, but there’s a big problem with that: spectrum is still limited, and even though 4G technologies help use it more efficiently, it’s still a constraint that the FCC is going to need many years to solve. We’re not sure how much the spectrum crunch really factors in here, but in addition to his comments on Droid Incredible inventory problems , Verizon Wireless boss Lowell McAdam mentioned at a Barclays Capital conference this week that he hopes to move away from unlimited plans altogether for the company’s LTE network, instead charging for “buckets” of megabytes, just like in the olden days — despite the fact that it’ll cost it a half to a third of what it costs today to transmit the same amount of data. On a happier note, McAdam said that the company expects to be using its LTE network for voice by 2012, which comes just after its first volley of LTE-capable handsets in early 2011. He also mentioned that at least some of those devices will be shown off at CES 2011, and naturally, we’ll be there — not just to check out the phones, but to raise some hell at the notion that unlimited data is a thing of the past. At this rate, how are we ever going to run the Engadget servers on a wireless connection?
