LightSquared swapping spectrum with Inmarsat

The wholesale 4G operator trying to “de-frag” its satellite spectrum, optimizing it for LTE deployment.
New 4G operator LightSquared is swapping out spectrum with fellow satellite operator Inmarsat in an effort to align its frequency holdings with its long-term evolution deployment plans.

Though LightSquared has received FCC permission to use its 59 MHz of L-band satellite spectrum for terrestrial mobile broadband services, the interlaced L-band licenses are hardly optimized for a wideband 4G deployment. LTE uses orthogonal frequency division multiplexing access technology, which through the use of sub-channels can spread a single LTE carrier over virtually any amount of spectrum. The more contiguous spectrum an operator packs into that channel, the more capacity it can offer over a single wireless carrier, while still effectively using the same infrastructure.
