Buying Guide: Facts About 3G/4G Networks

1: There is an official definition of 3G, but "4G" is just a marketing term so far. A 3G network must consistently deliver speeds of over 144 kilobits per second, while moving. Still, even though 4G has no real meaning, it's a useful term to describe newer, incompatible networks which follow 3G.

2: The fastest AT&T download we saw, at 5.05 Mbits/sec, was right behind Apple's headquarters at 1 Infinite Loop in Cupertino, CA. Of course the home of the iPhone would have the best AT&T signal!

3: The fastest connection in any of our tests was a blazing 9.11 Mbits down on Sprint 4G in the Midtown neighborhood of Atlanta, GA.

4: The slowest city, on average, was Raleigh, with average 3G downloads of 880kbits/sec.

5: The fastest city was Dallas, whose 1.7 Mbits/sec average was boosted by strong performances from both T-Mobile and Sprint 4G.

6: T-Mobile's HSPA+ rollout is making a dramatic difference in speeds. We saw HSPA+ in New York, Dallas, L.A., and Charlotte. T-Mobile's average download speed in those four cities was 1.91 Mbits/sec, compared to 927 kbits/sec where they haven't started rolling out HSPA+. That's a huge change.

My Experience

I'm that 5G guy. I've actually been here for every "G." I reviewed well over a thousand products during 18 years working full-time at PCMag.com, including every generation of the iPhone and the Samsung Galaxy S. I also wrote a weekly newsletter, Fully Mobilized, where I obsessed about phones and networks.

My Areas of Expertise

  • US and Canadian mobile networks
  • Mobile phones released in the US
  • iPads, Android tablets, and ebook readers
  • Mobile hotspots
  • Big data features such as Fastest Mobile Networks and Best Work-From-Home Cities

The Technology I Use

Being cross-platform is critical for someone in my position. In the US, the mobile world is split pretty cleanly between iOS and Android. So I think it's really important to have Apple, Android and Windows devices all in my daily orbit.

I use a Lenovo ThinkPad Carbon X1 for work and a 2021 Apple MacBook Pro for personal use. My current phone is a Samsung Galaxy S21 Ultra, although I'm probably going to move to an Android foldable. Most of my writing is either in Microsoft OneNote or a free notepad app called Notepad++. Number crunching, which I do often for those big data stories, is via Microsoft Excel, DataGrip for MySQL, and Tableau.

In terms of apps and cloud services, I use both Google Drive and Microsoft OneDrive heavily, although I also have iCloud because of the three Macs and three iPads in our house. I subscribe to way too many streaming services. 

My primary tablet is a 12.9-inch, 2020-model Apple iPad Pro. When I want to read a book, I've got a 2018-model flat-front Amazon Kindle Paperwhite. My home smart speakers run Google Home, and I watch a TCL Roku TV. And Verizon Fios keeps me connected at home.

My first computer was an Atari 800 and my first cell phone was a Qualcomm Thin Phone. I still have very fond feelings about both of them.
