LightSquared is currently conducting LTE network trials in Baltimore, Denver, Las Vegas, and Phoenix, and says that it plans to launch commercial service before the end of 2011. The company hopes that its network will reach 100 million potential customers before the end of 2012.

Though LightSquared has not announced any retail partner, market, or pricing scheme yet, the company says that devices including data cards, mobile wireless routers, and embedded modules (such as modem chips inside laptops) will account for the first wave of end-user access equipment. Smartphones designed to access the LightSquared network are scheduled for production in 2012, the company says.

In addition to the Best Buy deal, LightSquared has announced some lightly defined deals with Leap Wireless's Cricket brand (for unspecified 4G roaming coverage) and with , in a partnership that is not yet fully defined. The Best Buy deal seems solid and impressive--Best Buy has agreed to resell LightSquared service under its Best Buy Connect brand--but trials won't begin until 2012, and no plans, devices, or markets have been announced.
