After FCC gives the few companies a go signal to activate its wireless technology called LTE-U in their based stations, T-Mobile officially declared their most recent attempt to expand its network. The T-Mobile additionally announced that the said expansion will be rolling out support for the high-frequency network this year.

According to TC, basically, the idea behind LTE-U is that there are few frequencies in the 5GHz band that is used by Wi-Fi routers were definitely going to be unused. The carriers and device manufacturers proposed allowing these licensed bits of spectrum to expand the existence of base stations' signals, which potentially enhanced its short-range connection speeds.

However, the technology that is being developed by Nokia and Ericson recognized and opens up small, unused parts of the spectrum to boost its connections to smartphones and any other cell phones at up to gigabit speeds. It is a technique that has been trying to do for quite a while with T-Mobile Germany and was the first to run a trial program of the method.

Android Police reported that the idea is still genuinely fresh, with just a small amount of customer devices made having this kind of support for data connections on these ultra-high frequencies. The processing is needed to be complex to ensure that the high-speed LTE on the system does not interfere with the current wireless electronics on the 5GHz band.

The FCC representative said that the transmitters have already been approved as LTE base stations before. The grants were issued presently are for the capacity for the devices to work under Part 15 rules that run in the 5GHz band.

If the phone is new, it might be already supported with LTE-U on the hardware level, at least. Just like Qualcomm's X15 LTE modem, which includes a preliminary support for data connections on the unlicensed high-frequency band. The current T-Mobile phones will likely need a software update to empower the functionality of LTE-U.
