The last few years have been a tumultuous time for LightSquared, with the company's LTE plans facing one hurdle after another that eventually led to a bankruptcy filing. It looks like at least one company is now looking to buy its most valuable asset, though, with Bloomberg reporting that Dish Network Chairman Charlie Ergen has put a $2 billion offer on the table for the company's wireless spectrum. That's yet to be confirmed by either party, and Bloomberg reports that the offer is a so-called stalking horse bid, which could still let others put in a higher offer of their own. As Bloomberg also notes, this all comes at the same time that Dish is looking to buy Sprint for over $25 billion, both of which would need regulatory approval before going through.
