Research released today by XCellAir, an expert in Wi-Fi Quality of Experience , has revealed that operators could fail to capture up to $18bn of opportunity cost if they continue to poorly manage unregulated spectrum. The study, conducted in partnership with independent telecoms analyst Real Wireless, shows that poor management of Wi-Fi assets severely limits such assets' usefulness in dense urban environments where many access points are deployed to serve large numbers of users and large volumes of data.
