LightSquared faces a tough task. It not only has to find a fix for the interference problems its long-term evolution (LTE) creates for GPS, but it has to convince the FCC, the GPS device industry, government agencies and now lawmakers that its solution will work.
The burden of proof definitely weighs heavily on the wholesale operator. But both the government and the GPS industry have every incentive to work with LightSquared to find that fix. For GPS device makers, the incentive is one of pure business interest: The mobile broadband networks LightSquared and other operators build will ultimately make their products more powerful and more useful. The advent of 3G sparked a revolution in GPS and location, providing a two-way data channel that added real-time context and information to mapping and location data. Assisted GPS in smartphones and feature phones has spawned a huge location-based services sector.
As mobile broadband scales, the potential exists for any conceivable consumer device to become connected wirelessly. We're seeing it with laptops and tablets today. Soon we'll see it in cameras, game consoles, digital media players and automobiles. In the vertical markets, agricultural and construction equipment, shipping containers, trucks and any manner of high-value industrial asset are being outfitted with machine-to-machine modules (M2M). As all of these mobile devices gain access to real-time information, their location context will become all the more important—a huge boon for the GPS industry.
But in order to support those billions of mobile broadband connections, the wireless industry is going to have to build a lot more networks over a lot of spectrum that wasn't originally designated for cellular use. To get that kind of ubiquitous mobile broadband coverage, the FCC will have to clear not just the satellite L-band for wireless, but government and broadcast bands—by some estimates operators need to quintuple current spectrum resources to support the expected demand for mobile data. Regulators will have to scour the electromagnetic spectrum up and down to find new frequencies. Interference issues will abound and incumbent licensees are sure to protest. The LightSquared ordeal is a harbinger of things to come.
