![]() ![]() In 2017, the FCC concluded a unique type of auction - called a reverse auction or incentive auction - that managed the process of TV stations selling the spectrum to mobile network operators, and relocating TV channels that were previously using the band. The band was previously used for UHF TV channels 38 - 51. Therefore this band should provide superior service in rural areas and inside buildings. Lower frequencies travel farther and penetrate solids better than higher frequencies. ![]() This band is a lower radio frequency than most other bands used for mobile phones. Each block is 10 MHz wide, consisting of 5 MHz for uplink + 5 MHz for downlink. ![]() The band is divided into seven equal-size blocks (A-G). It's a paired band, so 617 - 652 MHz is for towers to transmit to mobile devices (downlink), while 663 - 698 MHz is for mobile devices to transmit to towers (uplink). The band covers the range of 617 - 698 MHz. They deployed LTE 4G in this band in late 2017, and added 5G in this band in late 2019. In the US, T-Mobile owns the licenses to most of band 71. With my current S8 now, it does not have the band 71 from what I saw so I have not noticed anything so far.A radio frequency band near 600 MHz, used for mobile phones starting in 2017.Īs a newer band, it is used exclusively for newer technologies such as LTE (4G) and NR (5G). So if you had a phone with no Band 12 coverage you went from "works everywhere in the lower peninsula" to "HALF THE STATE gets a big fat red X with no signal".Oh gosh. When they did their former roaming agreements with Centennial-***-AT&T were shut off essentially overnight. Little impact at first, then they suddenly rolled out half the state of Michigan more-or-less "all at once" for Band 12 - pretty much everything north of Lansing. T-Mobile's Band 12 rollout went like that. ![]() If it's more than that you are very, very likely to find this debilitating. If your expected "primary device" lifetime is one year you probably won't mind the lack of band 71 much. ![]()
