Trai on April 26 announced stringent reporting rules around base stations, asking operators to provide granular details like site location, radiating frequency, backhaul connectivity, technology utilised like 2G, 3G, 4G, 5G and the time of commissioning of a site, as it looks to improve the quality of service (QoS) and address the problem of call drops. The operators were against the regulator s move to seek such granular data.
