Using eight identical Samsung phones, the drivers tested out eight separate networks for four major carriers across 30 cities evenly spread across six regions. Using Sensorly's 2013 software, a broad suite of tests were conducted every three minutes: a 'ping' to test network latency, multi-threaded HTTP upload and download tests including separate 'time to first byte' measures, a 4MB single-threaded file download, a 2MB single-threaded file upload, the download of a 1MB Web page with 70 elements, and 100kbps and 500kbps UDP streams designed to simulate streaming media. Nearly 90,000 data cycles later, the data not only revealed the fastest networks (AT&T) and the most consistent (Verizon), but also other interesting points. The tests recorded the fastest download speed (66.11 Mbits/sec) in New Orleans and the best average in Austin (27.25 Mbits/sec), both for AT&T's LTE network. The tests also found T-Mobile's HSPA network to have the worst Average-Time-To-First-Byte, even when compared with AT&T HSPA network. Also according to the tests, Sprint's LTE network didn't even come close to competing with other LTE networks, to the point that in some cities its LTE network speed averaged less than T-Mobile's HSPA network speed."
