Wireless Speed Index
Notable Points. January 2018
For January 2018 T-Mobile and Verizon are both still have run away when it comes to network performance on a nationwide level, on average they are both significantly faster than AT&T and Sprint across the country. For network quality they are they both have broken and been able to stay above 65% of the time having 10 Mbps or greater download speed. Both T-Mobile and Verizon were the fastest network in 16 of 40 cities tracked and have put a nice gap between them self's AT&T and Sprint when you look at our long term chart.

AT&T was fastest in only 5 cities but was the second fastest in 15 of 40 tracked, Sprint was fastest in 3 but second fastest in 5 of 40 cities tracked. This is generally how it has been for the longest time now, we are not seeing much to suggest this is going to change but things have improved significantly for Sprint across the country. Getting close to a 20 Mbps national average download speed Sprints network does continue to get better month after month.

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 01/1/2018 - 01/31/2018.
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.
