Google said groups including the Wireless ISP Association and the Wireless Innovation Forum favor a similar plan. The Utilities Telecom Council said it supports the FCC’s general approach on grandfathered wireless protection zone (GWPZ), but believes they should be larger than the agency proposed. “As the comments of UTC and several utilities on the record explain, the GWPZ should be expanded because utilities have made significant investments in the 3.5 GHz band (3550-3700 MHz band), and the reliability of these systems must be maintained in order to ensure the safe, effective and secure delivery of essential electric, gas and water services to the public at large,” UTC said in reply comments. “Utilities represent the significant majority of incumbent systems in the 3.5 GHz band, and the GWPZ uniquely impacts utilities.”
