Does T-Mobile Wifi for Home 5G use the 5G UC?

pugachev1952, 

I could make one suggestion that may help you out. The cellmapper.net site provides information about cellular tower locations for multiple vendors. You can go to cellmapper.net and look for 5G towers in your location for a specific vendor. If you see towers that are transmitting n41 which is the mid-band spectrum then you would see UC however, there is a BIG thing to watch for here. Look at and determine how far the 5G towers are from your home. Also consider the topology. If there are hills and trees and you are in a low spot or on the other side of a large ridge from a 5G tower signal delivery could be sketchy. The n41 delivery has a realistic reach of 2-3 miles given conditions are taken into consideration. If you are on a higher elevation and have a clear line of sight to a 5G tower with n41 and within 1-2 miles of the tower and cell delivery well then you have a very good chance of getting good results. If you are 5-6 miles away from that same tower it is too far away. 

The most common solution I have seen are many n71 towers and some n41 but the n41 delivery is usually in high density population areas. Urban vs rural. One thing to consider about the marketing is the use of the term UC or ultra capacity. Hum… maybe that implies the vendors intend to stack up the subscribers off such systems and rely upon QoS as a mechanism to share the spectrum delivery. 

The bottom line is you can research a bit and if you have a 5G phone that supports the mid-band frequencies you can use it to locate towers. The Apple iPhone allows you to use Field Test Mode. In effect you dial *3001#12345#* to put it into field test mode and it will report the cellular signal information to you. 

CellMapper.net is on the whole about 80% accurate for information users have contributed. It is not perfect but it is one of the best tools out there for finding towers. There is always war driving to find towers but it is very time consuming.
