ZK Celltest

has received a three-year contract from OnStar to deploy in-vehicle monitoring systems that will test and measure wireless networks across the U.S. and Canada. The ZK Celltest real-time collection units (RCUs) will be installed in cars manufactured by General Motors, OnStar’s parent. The RCUs will generate test calls automatically, log performance data and location information, and relay the data to ZK Celltest, which will use the data to provide OnStar with maps and reports it can use to alert wireless carriers about network coverage problems.
