Regardless of the success T-Mobile has had with its Uncarrier initiative, one thing is clear: T-Mobile’s coverage doesn’t look great compared to Verizon’s and AT&T’s. To combat this, T-Mobile is looking to have its devices work better in homes and buildings, and it’s asking the FCC to help make that happen.

In order to provide phone service in buildings and in heavily trafficked, metropolitan areas, carriers need to provide service on low-band frequency spectrum. And in order for T-Mobile to acquire more low-band spectrum, it is fighting the FCC to change a few things. In a post on the official T-Mobile newsroom website, Kathleen Ham, T-Mobile’s Vice President of Federal Regulatory Affairs, has laid out a few changes T-Mobile is requesting from the FCC in order to help T-Mobile acquire low-band spectrum, and enable them to provide service that will “penetrate building walls better and travel longer distances than we can with the spectrum we have today.”
