Wireless Speed Index
Notable Points. December 2017
For December 2017 T-Mobile and Verizon are both the run away when it comes to network performance on a nationwide level. Both networks appear to be very evenly matched when it comes to speed. Verizon has made gains in the last few months after their unlimited data speed drop to catch up to T-Mobile. Verizon was fastest in 17 of 40 cities, T-Mobile was fastest in 14 of 40 cities tracked. Both Verizon and T-Mobile have started to run away from the other 2 networks when it comes to both download and upload speed. For Sprint, it may have taken all of 2017 but it is finally starting to get into the mix as our long term chart shows.

AT&T had a interesting, flat year that for download speed performance ended pretty much where it started. Any gains they might have had were lost likely because of offering unlimited data again and plans that are capped at 3 Mbps. We will be watching to see if this changes in 2018 and were every other network goes thought out the coming year.

What's it about?
That's what this "State of LTE in the US" index answers monthly. All data for this index is crowd sourced and gathered through the SpeedSmart Speed Test app for iOS and Android. Every month users take millions of speed tests using our app, this gives us an edge because our data is provided only by users not by ISP's or companies driving around in a van. That means we get real data from real people using their device in normal ways and at locations like your home or office, places you actually use data. The index is updated monthly so be sure to check back and see who's the fastest.

To help understand how we come to our conclustions we offer a small raw data sample avaiable for you to download here. This small sample of test data from Orlando, Florida taken between 12/1/2017 - 12/31/2017.
What is this 200 point scale thing?
It's a simple system we use to award a winner each month. A network is given 10 points for each section (Fastest Download, Fastest Upload, or Lowest Latency) they win, 5 points for each region won for download or upload speed, 3 points per city where the network has the fastest LTE download will be given. There is 200 total points available, the network with the most points is the fastest for the current month.
