Study Findings

Overall Findings Most users are urban Most robust solutions should focus there All have needs for high bandwidth (>1MB) Metro Wi-Fi is the clear solution but is too complex and costly to deploy and operate Mission critical users require multiple network alternatives Private sector hedge Many assets available that are valuable to 3rd party wireless providers Countless numbers of unique applications AMR, ITS, GIS, GPS, asset tracking, remote surveillance……..endless Cooperative County Environment
