The use-case like energy, mining, oil and gas moving towards industrial IOT (IIOT) applications for their day to day activities and this demands wireless connectivity every where. The Wi-Fi solutions are good for indoor but its hard to cover large outdoor areas with less Wi-Fi access points (APs), this leads to more APs deployment, cabling and infrastructure cost. On the other hand, public cellular networks offer an alternative, their limited proximity to refinery sites introduces difficulties. Mobile Network Operator (MNO) deployments are often situated far from refineries, and their base stations struggle to penetrate metal pipes, resulting in unreliable network connections and frequent disruptions to applications. To address these challenges, our approach involves deploying a private network on the Citizens Broadband Radio Service (CBRS [1]) spectrum, specifically in the 3.5 to 3.7 GHz mid-band range, within the refinery premises. This is the first measurement based commercial deployment ensures a robust signal footprint, even within metal pipes, thereby enabling employees to seamlessly utilize their devices and carry out daily tasks without encountering connectivity issues.
