Re: 28 GHz for 5G
davishoffman5

"28 GHz is useful for what? Point to Point with solid dish antennas at each end?"

A direct LTE deployment replacement, at the reduced range of 1.4 miles radius per base station. In other word, 28 Ghz 5G base stations need to be deployed at a 2.8 mile interval between deployment sites to provide a continuous coverage.

"It cannot penetrate walls or foliage very well."

The 5G handset will have to fall back to LTE when in a poor reception area. But still, there are tons of outdoor places where the 28 Ghz 5G would work, even inside a car cruising on highway at 65 mph.

"Now they say they can use something like 28 GHz?"

It is not the cellular networks that's pushing the 28 Ghz band, it is FCC that's doing that, and they got convinced after visiting Samsung's Austin lab to witness that the 28 Ghz 5G did work in real life outdoor conditions. Samsung's goal is that the world press would do the same at the 2018 Pyeongchang Olympics, where the journalists get to play with specially prepared 5G Galaxy loaner phones and write home how the 5G was here today, in their hands.

28 GHz for 5G
28 GHz is useful for what? Point to Point with solid dish antennas at each end? It cannot penetrate walls or foliage very well. The cellular companies took OTA TV frequencies because they needed penetration.  Now they say they can use something like 28 GHz?

AT&T tests
So we have an idea of what they could do with 3.5Ghz, 15Ghz, and 28Ghz, but use are the 4Ghz radio tests I wonder?
