Wireless Speed Index
Notable Points. August 2017
For August 2017 T-Mobile saw little to no gains in performance while both Verizon and AT&T saw about a 4% gain each month-over-month, we believe this flat line is in part due to customer growth. T-Mobile maybe acquiring customers faster then their network can keep up with, we believe this in part because over the past month we have seen the number of speed tests taken from T-Mobile users rise by 50% but performance remained flat. Verizon after having a sharp drop in network performance after introducing unlimited data earlier this year is starting to get close to where it was before it’s drop, network performance wise. At this rate Verizon will likely gain back the top speed crown in the next month or two bearing no changes with T-Mobile.

Sprint was the only network to see a drop in performance for the month of August, almost 4% month-over-month and only being the fastest in 1 city of 40 tracked. Verizon was fastest in 18, T-Mobile in 16 and AT&T was fastest in 5 cities. We will be watching over the next month for any major changes with many new phones coming to all 4 networks.

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 8/1/2017 - 8/31/2017.
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.
