Bellevue, WA-based Root Wireless, a maker of technologies that analyze and map the performance of cellular networks and devices, announced today it has closed $3.25 million in Series B funding co-led by Fred Warren and Oliver Grace, Jr. Also participating in the round were existing investors Scott Anderson, Jack Roberts and John Stanton. Root Wireless formed a partnership last month with CBS Interactive to allow the tech news site CNET to post maps of cellular network strengths and weaknesses. The startup, led by CEO Paul Griff, currently tracks network performance in eight metro areas around the U.S., and is mapping 12 more. News of the funding was first reported by TechFlash.
