SOUTHFIELD – Verizon Wireless took top state honors in the nation and in Michigan in the latest RootMetric’s National RootScore study of the nation?s four largest U.S. wireless providers.

Verizon won the Overall Performance Award in Michigan and also scored first in the categories of call, data, reliability and speed.

Michigan?s 4G LTE network from Verizon is complete, with the company already expanding AWS spectrum, or Advanced Wireless Service, in various locations in the state. AWS was not measured for this report, which would likely deliver higher speeds.

Verizon began introducing 4G LTE in Michigan in the fall of 2010. Both in Michigan and nationally, the rollout is substantially complete making Verizon the first wireless provider to complete a 4G LTE network with higher speeds.

The Verizon network is now twice as largest as its nearest competitor.

The company has invested $9.4 billion in its wireless network alone during 2013. Of that amount, $160 million was invested in Michigan in 2013 to ensure customers have the most reliable network available.
