The Un-carrier has been focusing on making sure all of its spectrum is being used for quite some time and thanks to approval from the FCC, they are continuing that. The carrier has announced that beginning this Spring, the rollout out of LTE-U will begin. LTE-U will be made up of 20 MHz of underutilized unlicensed spectrum on the 5GHz band, which provides more capacity for T-Mobiles 4G LTE network.
This new LTE-U network can be seen as using spectrum that would be other wise by wasted. The equipment that makes this possible, from Nokia and Ericsson is being deployed now, takes the underutilized spectrum that could be used for WiFi and repurpose it. Rather than laying out a new cell site, T-Mobile has the opportunity to reuse spectrum that is underused for wireless networks
In return this means the customer’s network experience on T-Mobile will be boosted to an even higher standard. Thus continuing the neck and neck battle between T-Mobile and Verizon to build out a larger network. While T-Mobile is first out of the gate when it comes to LTE-U, I wouldn’t be surprised to get an announcement from AT&T, Verizon, or Sprint announcing the same use of spectrum.
