LightSquared's LTE hopes dashed by federal agency report
When it was first mooted that LightSquared's LTE technology might interfere with GPS equipment, the firm was quick to deny it. Since then, the company has tried to mitigate the issue, but the nine agencies making up the National Space-Based Positioning, Navigation and Timing Executive Committee (PNT ExComm) all agreed that the problems are real and any attempts at mitigation are futile. This comes only days after Sprint reneged on a resource sharing deal, issuing a further blow to the company's plans for a terrestrial network. LightSquared's reaction is naturally not a happy one, claiming that the testing process is not only flawed, but that the agencies have a bias in favor of the GPS industry. By our reasoning, this only leaves the stage of depression before final acceptance of the grief-ridden situation.
Editorial: How FAA-certified gadgets could improve air travel and eliminate the Terrible 10,000 Feet
If you're reading this now and have experienced the wonders of modern air travel then you have surely suffered through what I call the "Terrible 10,000 Feet." This is the period between the clunk of the cabin door closing and the bong of the cabin indicator, the chime signifying arrival of the magic altitude where "approved electronic devices" can then be used again. The first half of the worst part of the flight is then over -- the latter half to commence as soon as the plane dips again below that gadget ceiling. This is the loudest part of the flight -- engines throttled up, flaps and gear hanging in the breeze and scared kids doing their best to drown all that out with screams and shouts. It's exactly when you most want to use your portable music player, and exactly when you aren't allowed. We've been told that this is for safety reasons, to prevent interference from the myriad devices carried by a cabin full of passengers, but that's never quite felt satisfactory to me. (Why is it okay to use those very same devices over 10,000 feet? Why can pilots use iPads but I can't?) So many questions, but I'm not here to second-guess the people whose jobs it is to keep me safe as I schlep myself, my roller bag and my personal item across the country yet again. I'm here to propose a very simple solution: a certification program in which manufacturers submit devices for testing and the FAA charges a (possibly hefty) fee for their approval. It could not only improve the lives of frequent travellers like myself, but could also stand to provide millions in funding to the FAA, funds that could be put toward its unfortunately named NextGen air traffic control system. Win win? Read on and decide for yourself.
LightSquared proposes 'simple, affordable solution' to that pesky GPS interference issue
It's not the first "solution" that LightSquared has proposed for the GPS interference issue that's gotten in the way of its LTE network rollout, but the company's now touting a new "simple, affordable solution" to the problem. That doesn't actually involve any changes to the network itself, but rather changes to the high-precision GPS hardware that is being interfered with. To that end, the company has announced that it's signed an agreement with Javad GNSS, which says that it's been able to reconfigure the filters and linear amplifiers used on existing receivers and make them "completely compatible with LightSquared's bottom 10 MHz of spectrum." According to Javad, those changes are not expected to increase selling price of newly reconfigured devices for consumers, although there would presumably be some cost to retrofit existing devices (the first units for testing are expected to be available next month). So, it may be "simple" and "affordable," but it doesn't seem like it's necessarily an "easy" solution. LightSquared's press release is after the break.
OnLive CEO reveals 'entirely new approach' to wireless, credits Rearden for toppling Shannon's Law
"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.
LightSquared announces 'solution' for GPS issue, says LTE network will roll out on schedule
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. [Thanks, Nick]
Government report finds LightSquared's LTE interferes with GPS -- color us surprised
No one said bathing the great United States in LTE would be easy, but the hits just keep on coming for Falcone and co. Following up on reports and concerns about LightSquared's possible interference, a government study has found that the outfit's proposed broadband network does indeed impede GPS signals. According to the National PNT Engineering Forum, the federal advisory group that conducted the study, LiqhtSquared's network disrupted GPS signals for all of the devices tested in the area. The report lists OnStar, Garmin, John Deere, emergency services, the FAA, and NASA among those affected by interference. Both LightSquared and the GPS industry are scheduled to present their own tests for the FCC's consideration next week. The news isn't exactly shocking, but it certainly doesn't bode well for the ambitious LTE network.
LightSquared's LTE breaks GPS in New Mexico trial, angers John Deere
With Best Buy, Cricket, and Leap already signed on as partners, LightSquared has a lot riding on the success of its nationwide LTE network. Unfortunately, the Airforce's concerns about it interfering with GPS have been born by a test run in New Mexico. Officials in charge of the state's 911 systems as well as trucker hat kings Deere & Co. reported loss of service up to 22 miles away from LightSquared's cell tower. The company believes it has a solution to the interference problem, but hasn't specified exactly what the fix might be. Now the 4G wholesaler's future rests on a June 15th report to the FCC detailing the potential issues for both consumer navigators and the precision GPS systems used by the military and airlines -- but when even John Deere is lobbying against you things start to look a little bleak.
Cellular South inks deal with LightSquared, gets LTE with stroke of a pen
Cellular South just dropped a nugget, announcing it's hopped aboard with LightSquared to provide nationwide LTE service to its 900,000 subscribers. In turn, the 4G wholesaler promised to bring coverage to rural communities (and offer satellite service for those in really distant locales). Cellular South joins Cricket, Best Buy Connect and SI Wireless as the latest to add LTE coverage the easy way, though they're left waiting for the network to come online sometime in 2012. Meanwhile, LightSquared continues working to resolve those pesky GPS concerns, with a final report due to the FCC on June 15th. PR after the break. [Image courtesy Flickr]
China, predictably, denies Google's accusations of Gmail tampering
On Monday, Google expressed its belief that its email users in China were experiencing "a government blockage carefully designed to look like the problem is with Gmail." Now, as is par for this thorny course, the Chinese state has come out with a terse rebuttal, saying simply that "this is an unacceptable accusation." The retort was, says the BBC, part of a regular news conference on Tuesday and it doesn't appear that any more time was spent on the subject. Which is odd since most people would tend to act to prevent something they see as unacceptable -- but then we suppose China already has a pretty long list of folks it'd like to shut up, Google's just gonna have to get in line and wait its turn. There's a good citizen.
Google and China clash again, this time over Gmail access
Last week we noted, with a growing sense of disquiet, how China was busying itself with locking out VPN access within its borders and, seemingly, preventing people from using their Gmail accounts. Google has now given a public voice to those concerns, noting that "there is no issue on our side. We have checked extensively. This is a government blockage carefully designed to look like the problem is with Gmail." Other Google tools, like the Person Finder for Japanese tsunami survivors, have also exhibited intermittent issues. China's goal in these attacks is reportedly to stifle online revolutionary chatter inspired by Egypt's successful democratic revolt, though the nation's said to be taking a more clandestine approach than previously by making its alleged sabotage appear like a software problem instead. Guess it's time to prepare ourselves for another battle of wits between these two.
US Air Force raises concerns over LightSquared's LTE network messing with GPS
Following a navigation system's instructions without driving into a ravine is hard enough as it is -- can you even imagine how hard it'd be if you kept losing GPS reception every time you drove within range of an LTE tower? There have been a few anecdotal concerns raised over the last several weeks that LightSquared's proposed LTE network -- which would repurpose L-band spectrum formerly used for satellite -- is too close to the spectrum used by the Global Positioning System, leading to unintentional jamming when the towers overpower the much weaker GPS signals. Things have gotten a little more interesting, though, now that the US Air Force Space Command has officially piped in. General William Shelton has gone on record saying that "a leading GPS receiver manufacturer just ... has concluded that within 3 to 5 miles on the ground and within about 12 miles in the air GPS is jammed by those towers," calling the situation "unbelievable" and saying he's "hopeful the FCC does the right thing." Presumably, the USAF thinks that "the right thing" would involve pulling LightSquared's license, but for its part, the company says it believes Shelton is referring to a test conducted by Garmin (possibly explaining that recent outage in the Southeastern US?) using simulated interference filters -- not the actual filters that it has spent several million dollars developing and perfecting. Regardless of how effective the filters might be, the idea that the only thing standing between a functional GPS system and a constellation of space-borne paperweights is a private company's privately-developed, privately-operated filtering equipment... but then again, we love LTE. Decisions! [Thanks, Brian]
Perpetuum dev blog talks new features, Interference system
Wondering what's going on in the world of Perpetuum? Wonder no more, as the official Perpetuum dev blog has been updated with news of today's patch as well as a number of both client and gameplay tweaks. First on the agenda is the fact that Avatar Creations is now offering two new languages for its sci-fi sandbox, and we're sure both the Slovenian and French-speaking communities will appreciate it. The patch also features the introduction of a new heavy mech robot (the Lithus), which "can be thought of as the big brother of the Sequer, and will satisfy all your hauling needs" according to Avatar's BoyC. Next up are a couple of additions to the character screen in the form of trophies and losses followed by the coup de grace of this particular patch: the Interference system. In a nutshell, Avatar is attempting to address the fact that players are clustering together in PvP and one-shotting opponents due to a mass of concentrated firepower. The designers intentionally avoided implementing friendly fire and robot collision detection in Perpetuum, and the Interference system "simulates the effects safely fighting in a close group would have on the combat effectiveness of the group in the real world. Basically members of the group would have to be more careful not to shoot any of their comrades, and thus be slower to fire and would have to devote a lot of their attention to working together with their unit."
Double Stevemails on iPhone 4 reception: "Just don't hold it that way"
With so much to do -- counting profits, making FaceTime prank calls to Woz, rubbing hands together and laughing manically -- it's hard to believe that El Steve is taking time out of his very busy day to answer his mail. Yet answer it he does, if our two most recent tipsters are on the level. Both are telling a very similar story about Steve's answers regarding the iPhone 4's gripping signal issues. [In the latest news on the signal/contact problems, Boy Genius Report cites similar issues with some 3GS phones as evidence that the problem is a software hiccup in iOS 4, while MacRumors notes that bumper cases or other coverings for the 4 seem to resolve the problem. ArsTechnica wasn't able to reproduce the issue right-handed, but only holding the phone left-handed and with some effort. WhenWillApple has some electrical analysis that's worth a read.] It seems Steve is happy to suggest the Mel Brooks approach to resolving the signal issue -- if we hold the phone that way, we won't need any signal boost. Tipster Rory Sinclair recounts today's email thread with the Apple CEO on his blog: So, um, just got my iPhone 4. It's lovely and all, but this 'bridge the two antennae to kill your reception' thing seems to be a bit serious. If I bridge them with my hand or with a piece of metal the bars slowly drop to 'Searching...' and then 'No Service'. It's kind of a worry. Is it possible this is a design flaw? Regards - Rory Sinclair Steve's reply: Nope. Just don't hold it that way. Rory pressed the issue once more, got the same response, and pressed it again, saying "Normally there aren't limits to how you hold a phone" -- finally getting this response from Steve: Sure there are -- every phone has these areas of sensitivity, depending on the location of the antenna. Some phones even ship with labels warning customers to not cover certain areas with their hands. Oooookay. You might think this was a non-answer answer, but it's the same one (or nearly) that reader Craig Brockman got from his email to Steve: Gripping any phone will result in some attenuation of its antenna performance, with certain places being worse than others depending on the placement of the antennas. This is a fact of life for every wireless phone. If you ever experience this on your iPhone 4, avoid gripping it in the lower left corner in a way that covers both sides of the black strip in the metal band, or simply use one of many available cases. Craig's correspondence was even confirmed by MacRumors, which was granted access to his email account and validated the message headers. That phrasing starts to sound like Steve has turned to the marketing department for some boilerplate copy, since he may end up answering a lot of these emails over the next few weeks. In fact, Engadget and The Loop say that this particular verbiage is the company's official statement on the problem, and both sites hypothesize that the Bumper cases may alleviate the issue. If you've got signal issues on your iPhone with your normal grip, be sure to let Apple know -- then come back here and let us know, too.
Broadcasters seek to slow action on FCC's white space ruling
We knew they didn't like it, and now they're going out of their way to prove it. After FCC chairman Kevin Martin set forth a proposal to use the freed spectrum from the forthcoming 2009 digital TV transition for bringing mobile broadband to more locales, broadcasters who'd rather not deal with the trouble are stepping in with a collective "nuh uh!" Station owners and the four television networks filed an "emergency request" on Friday afternoon in hopes of convincing the FCC to hold off on its plan to vote on white space rules until "everyone had a chance to comment on the findings." The report that's mentioned found that no significant interference would come into play should the waves be opened up for unlicensed devices, but a spokeswoman for the National Association of Broadcasters stated that "the FCC is misinterpreting the actual data collected by their own engineers." Whether or not NAB will get the 45-day grace period it's asking for, however, remains to be seen.[Via Mobile Tech Today, image courtesy of Orbitcast]
High frequency processors could put your GPS on the fritz
Just when you think things couldn't get any more gloomy in the world of in-car navigation systems, here comes news that high frequency processors surrounding your GPS system could actually cause some seriously screwy routing. According to a study by the Swedish Defense Research Agency, "computers used near a NAV could disturb the signals utilized in the GPS receiver." More specifically, Intel CPUs with clock speeds of 1.7GHz, 3.0GHz, and 3.2GHz were pinpointed as potential troublemakers, but a member of the study actually went so far as to suggest that a variety of other (untested) chips could indeed wreak the same havoc. The study showed that "modern computers produce interfering signals that reach as far as the frequency bandwidths used for GPS systems," and while specific reactions weren't apparent, testers did suggest to move any computer equipment further away from the GPS unit if it began to "play up" for no ostensible reason. Of course, we've huddled our own laptops and GPS systems together on many occasions with no ill consequences, so as always, your miles may vary.[Via NaviGadget]
TiVo Series3 + plasma TV = big problems
So you just paid $800 for your brand new Series3 TiVo ($1,000 if you transferred your lifetime subscription), waited patiently as the morons from the cable company tried to get their heads around installing CableCARDs in a non-TV device, and finally sat down on your couch to begin recording and commercial skipping all that great HD programming -- just to find out that your damn TiVo remote doesn't work! As many home theater aficionados know (first-hand, unfortunately), plasma TVs emit a significant amount of EMI and RFI signals from their surfaces that can confuse nearby IR sensors and render them useless, especially if your home theater gear juts out in front of the display. Well this problem has been happening in spades to new Series3 owners, as the box's IR receiver seems especially sensitive to other frequencies, so much so that they often need to press a button 10 to 15 times for a command to actually register. TiVo seems to be aware of the issue, but has not yet offered a solution, which is why the good folks who frequent the TiVo Community forum have put their heads together and come up with several effective workarounds. The most ghetto of these fixes involves attaching a tiny opaque "hood" around the box's sensor window, so that plasma interference can't go through but line-of-sight remote commands are still received. Since you probably don't want an ugly piece of cardboard hanging off of your beautiful $800 device, forum user "lightspeed" has come up with a slightly more difficult but much more aesthetically pleasing alternative: after carefully disassembling your Series3, you simply need to attach 6 to 8 small squares of GLAD Press 'n Seal to the inside of the IR window on the front face plate, which will serve to shield the sensor from the bad signals but let the good ones get through. Good job, intrepid TiVo devotees, but what we wanna know is: out of all the folks who beta tested this product, was there not even one of them who used it with a plasma and could have caught this problem much sooner? TiVo: makes a great product, but needs a little help in the e-commerce and quality assurance departments.Read- ProblemRead- FixRead- Fix pics
Enjoying OTA HDTV broadcasts? Not if you live by an airport
In a report that may get more frequent as we move towards all-digital broadcasting, Nashua Telegraph writer Joe Konopka complains about aircraft knocking out his HDTV signal momentarily every night. Sure it was annoying after the nearby airport was built and sound pollution and radio interference affected his ability to get a good night's sleep or listen to the radio. But now that he's purchased a high definition television with a built in OTA tuner, losing picture during a tense moment of 24 is the simply unacceptable. Unfortunately, now that the airport is built he doesn't have much ability to change things and laments not joining forces with an environmentalist friend to get plans changed while the airport was still being built.Ouch. Any HD Beat readers dealt with a similar issue and have suggestions? (Other than switching to cable or satellite.)
Improving your AirPort reception, MacGeekery How-To
MacGeekry has just published a truly epic post discussing best practices for maintaining a strong and relatively interference free AirPort Network. The article, full of pretty graphs and shiny charts, explains how to use three free programs to check your network for issues, and how to fix any issues you might find. Although intended for owners of AirPort base stations, I imagine much of the information in the article applies globally for all wireless routers and access points. I haven't tried any of the suggestions yet, as I'm not at home, but I'd be interested to hear from you readers if this stuff really works.
