Hasta La Gadget!

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!

If you’ve been following the drama over LightSquared’s application to build a wholesale integrated broadband / satellite network, it’s time to put away the tissue box and toss out the bonbons. That’s right, the FCC finally approved the company’s conditional waiver for an ancillary terrestrial component integrated service rule. In other words, the entity gave LightSquared the green light to offer terrestrial-only phones, in addition to satellite service, as long as interference problems are addressed before the company starts building its network. Just two weeks ago, it looked like the FCC might strike down the proposal on a recommendation from the National Telecommunications and Information Administration (NTIA), which warned of potential interference on the SMS network with the likes of Department of Defense Communications. LightSquared remained silent during deliberation, but following the FCC’s decision, both parties gave a thumbs up to the outcome. Honestly, we could have done with a more heated back and forth, but we’ll leave that to the professionals. What time is Bridalplasty on again?

Last summer it looked like Philip Falcone’s LightSquared was on the path to a democratic LTE solution: a coast-to-coast network, incorporating satellite connectivity to cover the entire country. It’s an ambitious goal to be sure — perhaps too ambitious. In a letter to the FCC, the National Telecommunications and Information Administration (NTIA) warned that the wholesaler’s wireless network, which would operate on the MSS spectrum, could interfere with systems like Department of Defense communications. Here’s the snag: last year the FCC approved the company’s initial proposal to create a network that would incorporate both terrestrial and satellite services. Now LightSquared wants to offer the option of terrestrial-only phones to their clients. According to the NTIA, such a system would require far more land-based stations, causing potential MSS overcrowding and increasing the risk of interference with everything from aeronautical emergency communications to Federal agency systems. The FCC has yet to make a decision on the revised proposal, and LightSquared hasn’t made a peep, leaving us to wonder whether it was all too good to be true.

It may shock your senses, but this actually isn’t the first time we’ve heard of lasers being used to track birds and their habitats. But this go ’round, an Idaho University team is using a satellite-borne laser in an effort to “predict in which part of a State Forest the birds might be living.” In particular, the crew is developing methods that’ll help them track the North American pileated woodpecker, namely because these creatures are pegged as being great indicators of overall bird diversity. Currently, the laser is only capable of analyzing vital characteristics of a woodland, but scientists are using this information to take a stab as to where the aforementioned birds would be. Essentially, this laser spotting approach enables gurus to spot highly dense sections of forest — plots where the pileated woodpecker loves to hang — from above, dramatically cutting down the hide-and-seek that would previously take place on foot in much larger areas. Now, if only they could get lasers onto the birds, we’d have an all new brand of rave to consider.
