GWS: AT&T had the best coverage during the Presidential Inauguration

Leading independent network benchmarking specialists Global Wireless Solutions, (GWS) revealed the wireless connectivity performance experienced by inauguration attendees on Friday, January 20.

Using rigorous procedures, GWS network testing specialists used Samsung Galaxy S7 smartphones and the GWS Mobile Diagnostic App to evaluate the mobile network performance of the four major US carriers in terms of completing everyday tasks (such as making a phone call, uploading a video, sending a Snapchat, etc.) and the speed at which the data related tasks can be completed.

The sites tested include the National Mall and areas alongside the parade route. Data collected was then ranked using OneScore, a performance metric developed by GWS that considers both in-depth network testing data and an understanding of how consumers are using their mobile devices (based on a third-party survey vetting the sentiments of 5,000 US adult mobile phone users).

Findings include:

  • From the tests conducted it seems preparations paid off for AT&T. GWS deployed teams to measure network performance at the inauguration and based on the collected (in the National Mall) between 10am (i.e. pre-inauguration) through to the conclusion of the inauguration ceremony itself, AT&T ranked first in all of the GWS OneScore metrics measured – these include overall reliability (for both voice and data), overall packet data (considering data speed and reliability), social media tasks and data speed alone. AT&T was followed in the rankings by Verizon, T-Mobile and Sprint.
  • For data tasks collected on the Mall such as downloading or uploading a video (4MB file size), AT&T’s throughput was, on average, double that (or more) of their closest competitor. Additionally, Sprint’s and T-Mobile’s networks experienced very low levels of task success rate during the testing on the Mall – during this time Sprint failed more than 4 out of every 10 task attempts.
  • As the focus moved from Mall to the parade route (along Pennsylvania Avenue) the performance variations tightened across the operators and T-Mobile and Sprint significantly improved their overall performance. In fact, T-Mobile ranked first in the GWS OneScore rankings for the post inauguration parade.
  • However, when it comes to the voice reliability statistics, AT&T and Verizon provided the most robust network performance, beating out T-Mobile and Sprint throughout the day.

Methodology

Between 10am and 5pm on January 20, 2017, approximately 15,000 voice and data tests were conducted to evaluate network performance of Tier 1 carriers (AT&T, Sprint, T-Mobile, and Verizon) at major points throughout the presidential inauguration including the National Mall and parade route.

Using Samsung Galaxy S7 smartphones and the GWS mobile diagnostic app, tests were conducted to evaluate the mobile network performance of these carriers in terms of completing everyday tasks (such as making a phone call, uploading a video, sending a Snapchat, etc.) and the speed at which the data related tasks can be completed.
