Jim Rossman: I finally found the fastest 5G connection

Unless you've been under a rock, I'm guessing you've heard of 5G, which is a new technology to give our cellphones faster connections to the internet.

AT&T, Verizon and T-Mobile are all touting their 5G networks, and it's getting hard to find a new flagship phone without 5G. But what does it mean for you?

I was invited by AT&T to test drive its 5G network, and it wasn't as easy as it sounds.

First, let's talk about 5G.

I'm going to simplify this somewhat.

There are really two types of 5G networks: one called Sub-6, which is "regular fast," and millimeter wave, which we'll call "really, really fast."

 

When you see the commercials for the carriers that say they are covering the country in 5G, they mean Sub-6, or regular fast. Speeds can range from 50 to 150 megabits per second (this range is from my experience).

The mmWave, or really, really fast 5G, has speeds up to 2,000 Mbps, but it doesn't travel as far from the transmitter, so it is currently limited to certain "destinations" like AT&T Stadium, in Arlington, Texas.

AT&T sent a Samsung Galaxy S20+ 5G phone to test its 5G network, and it also sent a few locations where I could test the mmWave network to experience the really, really fast download speeds.

The list included Klyde Warren Park and the plaza at AT&T headquarters in downtown Dallas.
