T-Mobile is introducing a residential small cell for providing LTE coverage inside a home.
“Where the T-Mobile Wi-Fi CellSpot’s like a T-Mobile tower, this new 4G LTE CellSpot is a T-Mobile mini-tower—and it’s a huge feat of engineering,” said John Legere, president and CEO of T-Mobile. “The big difference between us and the carriers is that they’ll do absolutely everything they can to bleed you dry. We’ll do absolutely everything we can and use every proven technology available to give you the best coverage possible.”
