If you've ever dealt with a spotty LTE connection at home, you know how annoying it can be. You're paying a hefty monthly bill to use your highly advanced smartphone — that can't connect reliably to the internet in your own house.

Well T-Mobile wants to fix all that... by putting an LTE tower in your house. Yes, the unconventional carrier has announced a 4G LTE CellSpot that it says will offer 3,000 square feet of LTE coverage for your home or business. Plug it into the wall outlet, connect it to the internet, and your LTE connection will get a boost anywhere T-Mobile has spectrum. The CellSpot supports up to 16 calls at a time, and will work with any 3G, 4G, and LTE device on T-Mobile's network.

If enough customers adopt this, T-Mobile has essentially figured out a way to get its users to fill out its still noticeable signal gaps without having to wait until its towers catch up. While it may not be a move done with pure intentions, the LTE CellSpot could be great for users with coverage issues in their homes. And the price is right too — eligible Simple Choice customers can get the LTE CellSpot for free (with a refundable $25 deposit), and keep it as long as they are customers of T-Mobile.
