Test and Measurement: RootMetrics data supports remote learning in Texas
When school officials in Harris County, Texas sought to purchase wireless air cards to enable thousands of students to do remote learning, they made their purchase decisions in part based on network performance data from benchmarking and analysis company RootMetrics.
Harris County covers 1,700 square miles and includes the city of Houston, and it has a population of about 4.7 million people. As county officials considered how to address the connectivity needs of thousands of students across more than 30 school districts and more than 1,100 individual schools, they wanted to make air card purchases in each district based on which of the three national carriers had the best coverage in that local area. Even more importantly, RootMetrics says, school officials “needed to understand which carriers offered good signal conditions indoors so that students could experience uninterrupted remote learning.”
The county “had already gathered some coverage data using an application installed on county vehicles and were working with an outside consultant to help drive this project,” RootMetrics noted, and county officials relied on additional data from RootMetrics to fill the data gaps and create a “bigger picture with greater precision.”
“Harris County did not want to rely solely on carrier-issued coverage (marketing) maps to make decisions on the best cellular coverage in each school district,” said Jim McMillan, Assistant CTO for Harris County, in a case study from the company. “With more research, we determined our best course of action was to gather independent, third-party data to ensure we are making the most informed decisions.”
RootMetrics found that T-Mobile US had the best indoor signal strength in 66 zip codes across Harris County, compared to 59 where Verizon’s was the best and 37 where AT&T’s was. “Multiple carriers did offer good indoor signal conditions in some of the same zip codes,” the company noted. Ultimately, RootMetrics said, its data “allowed Harris County officials to quickly determine which carrier’s air card was best suited for each zip code and bring reliable, high-speed internet connectivity to thousands of students in the area.”
