  • BAE Systems' NAVSOP does positioning without GPS, makes sure the only jammin' going on is yours

    Just in case GPS and GLONASS didn't make for enough of an acronym soup, BAE Systems wants to add one more to the navigation broth. NAVSOP (Navigation via Signals of Opportunity) uses some of the basic concepts we know from cell tower triangulation and WiFi location-finding to lock down a position, but goes much further to geolocate from nearly anything that pushes out a signal, such as nearby radios and TVs. It doesn't even need to know what kind of signal it's looking at, and it can get its position in places there's no GPS to work from, whether it's in an urban canyon or the natural kind. BAE is most excited about the prospects of ending GPS jamming against soldiers and UAVs, once and for all: not only is the new technology mostly impervious to attempts to block its signal, it can use the jamming attempt itself to get the position fix. Thankfully, the company's roots in defense aren't precluding use for civilians, so there's a chance that future smartphones might never have to use guesswork to get their bearings -- provided that governments around the world sign off on the idea, that is.

  • Frontline investigates the cause of cell tower deaths tonight (video)

    You probably don't give much thought to the towers that blanket us with wireless signals and the technicians that climb up them, almost constantly, to upgrade the equipment. The PBS investigative journalism series, Frontline, does and tonight on your local PBS HD affiliate the findings from their investigation of the numerous fatalities will premier -- check out the embedded preview and then the local listings for specific time and channel. Who's to blame, what can be done to prevent it and more will be covered, as well as discussed via an online chat with the film's producers on Wednesday the 23rd at 1PM ET, with one of our very own moderating the panel. Feel free to leave questions for the producers and then join us tomorrow via the embedded chat after the break.

  • AT&T small cell site pilot due between late 2012, 2013

    AT&T has been hinting for a while that it's getting closer to implementing small cell sites in its network, and at CTIA Wireless 2012 gave a stronger clue as to when and how the mini network hubs will operate. Executive technology VP John Donovan clarified to Reuters that a pilot is expected to start late this year and should run into 2013. If all runs smoothly, the below-tower-sized sites will be clipping on to lamp posts and other parts of the urban landscape to strengthen coverage in places where wide-area WiFi alone won't do. While Donovan didn't venture deep into the infrastructure at the trade show, Cisco had previously said that AT&T would be using sites incorporating 2G, 3G, 4G and WiFi when the provider did start experimenting with small cells. If so, there's a chance subscribers could get AT&T WiFi without having to turn to an airport, landmark or coffee shop.

  • Sprint allegedly talking to LightSquared over 4G infrastructure deal, Clearwire should be sweating

    Bloomberg is citing "three people familiar with the talks" (it's not often that we get a specific number!) as saying that LightSquared is in active negotiations with Sprint to use its network infrastructure as it builds out its L-band LTE network. As you might recall, LightSquared is the would-be 4G wholesaler that is in the process of repurposing some satellite spectrum for terrestrial LTE use -- a concept the FCC has approved, but concerns over GPS interference could end up delaying or derailing the strategy altogether if they aren't solved to everyone's satisfaction. Of course, building out any sort of national terrestrial wireless network is a multi-billion dollar, multi-year type of venture, and presumably a tie-up with Sprint to use some of its hardware would help move matters along. What this means for Sprint's existing dealings with Clearwire is unclear; the two operate a WiMAX network together, after all, but the carrier has made it clear in the past that LTE could definitely be an option in the future.

  • 'Signal' jailbreak app for iPhone maps out your towers, turns death gripping into a pastime

    If you're familiar with Android apps like CellFinder, you've got a good idea for what this is -- and the name "Signal" is a pretty accurate representation, too. Basically, iPhone Dev Team member planetbeing has thrown together a neat little app that shows you signal strengths of your phone's connections to nearby cell towers along with their position relative to you (if the positions can be determined), an especially welcome utility considering that you can't access Apple's old "field test mode" in iOS 4. Our favorite part, though, has to be planetbeing's desire to turn this from mere information into entertainment -- and to hopefully take the edge off your pain and deep-set resentment over the signal strength and call dropping issues in your iPhone 4 -- by adding a mode where your goal is to get the signal to drop completely, at which point you'll hear the voice of Spock announce a Vulcan death grip. Who knew an engineering defect could be so much fun? If you're jailbroken -- or you're willing to jailbreak -- you can score Signal in Cydia for a five-spot. Follow the break for video of the app in action. [Thanks, Pytey]

  • RIM finally catches up to the competition with non-GPS-based BlackBerry 'Locate Service'

    It's hardly the first company to implement the technology in a smartphone, but it looks like RIM finally has an answer for folks not satisfied with the GPS capabilities of their BlackBerry. It's now announced the simply-named 'Locate Service' for developers, which relies on cell tower triangulation to either augment the phone's built-in GPS, or completely replace it when a GPS signal isn't available. According to RIM, the service also includes a set of components that "integrate seamlessly" with the BlackBerry Maps and Contacts applications and, of course, the GPS capabilities of the device. There's still no word on any apps that actually take advantage of the new service though, but it is now at the disposal of developers, so we're guessing we'll see some soon enough.

  • Indian mobile carriers scramble as illegal towers are shut down

    Apparently the dizzying expansion of mobile coverage in India has proceeded a little quicker than the regulatory process there -- Indian carriers are in a bit of a tizzy after authorities shut down 300 allegedly illegal towers in a suburb of New Delhi called Noida. The gub'mint says the towers are on private land that's not approved for commercial use, but the carriers say the move is "arbitrary and uncalled for," and even "inhuman" because the loss of service means people can't make emergency calls. That's a strong card to play -- let's hope this gets sorted out soon.

  • Sprint mulling outsourcing network maintenance, transferring staff to Ericsson?

    Word on the street is that Sprint is currently in heated discussions with Ericsson -- the world's largest network infrastructure company -- to take over management and maintenance of its vast back end along with somewhere between 5,000 to 7,000 of the carrier's employees in an effort to lower costs by about 20 percent as its subscriber counts and tends both stay soft. Interestingly, Sprint already sold some of its towers to TowerCo last year for over half a billion dollars, so it's not clear exactly how Ericsson fits into the puzzle yet -- but at any rate, Sprint would apparently be paying something on the order of $2 billion over the next several years for Ericsson to do its thing. In light of this, it's kind of ironic that Sprint doesn't sell a single Sony Ericsson handset, isn't it?

  • UK study finds no link between illness and cellphone towers

    Researchers in the UK have all but debunked the theory that cell phone towers, or electronic interference, is making people physically ill. A recent study done by Britain's Health Protection Agency (HPA) said that they could find no scientific evidence that feelings of anxiety, nausea, and tiredness occur due to the presence of electronics, or GSM and 3G cell phone equipment. The tests, carried out in 2005 and reported in Environmental Health Perspectives today, claim that when neither the researcher nor the subject knew if cell signals were being emitted, the number of symptoms reported was not related to signals present. Participants did report feeling ill, but it was independent of any cell phone signals, "Hence the range of symptoms and physiological response does not appear to be related to the presence of either GSM or 3G signals," the study said. Yeah, right, next thing you know they'll be telling us those voices we hear aren't "real" either.[Thanks to everyone who sent this in]
