Docomo ranked first by GWS as Guam’s most reliable network

DULLES, VA – March 5, 2020 – Global Wireless Solutions (GWS) has today released the results of its first-ever competitive benchmark test of wireless connectivity in the U.S. territory of Guam. The comprehensive analysis conducted in December 2019 reveals Docomo topped GWS’ OneScore ranking for most reliable mobile network on the island. GTA was second in the ranking followed by IT&E then iConnect.

GWS’ OneScore rankings are based on a combination of real-world wireless network performance measurements and feedback from consumers on what they experience and want from their network. As a result, OneScore delivers the industry’s most comprehensive evaluation of mobile networks. The recent analysis conducted in Guam is part of GWS’ continued efforts to measure mobile network performance where people live, work and play around the world.

Other findings include:

  • Download Speeds: Docomo is the fastest for download tasks, such as receiving photos, internet browsing, and app-related content.
  • Capacity Stress Test: Docomo has the fastest throughputs during GWS’ network stress tests.
  • Coverage: Docomo showed the highest percentage of good coverage (superior signal strength) on the routes tested. In particular, GWS experienced good coverage on over 95% of the tests performed on Docomo’s LTE and UMTS networks (exceeding the percentages experienced on all other operator LTE and UMTS networks).

 “Our first-ever test program in Guam was a success that will provide a solid baseline to measure future analysis against,” said Dr. Paul Carter, CEO and founder of Global Wireless Solutions. “Over the course of several weeks, our team conducted 70,000 unique voice and data tests using both Android and iPhone testing platforms – revealing a full picture of true mobile network performance across the island.”


 GWS conducted this series of tests to evaluate mobile network performance across Guam. In particular, a total of 70,000 data and voice tests were conducted to evaluate the performance of Docomo, GTA, iConnect, and IT&E networks. The tests were conducted using the GWS OneMeasure App running on iPhone devices, Rohde & Schwarz’s Qualipoc test software using Samsung Galaxy devices, and the GWS MobiStat data evaluation and reporting platform.
