Along the pipeline, there are several compressor stations, which are located 12 miles (19.3 km) apart from each other. Each compressor station serves as an aggregation point of the field site, collecting information such as pressure and gas levels from the RTU devices and sensors. To manage the assets from a central location, the company used to deploy a 900 MHz serial radio for its long-distance communications system. However, the radio no longer functions as expected, making managing communications from a central location difficult. As the pipeline extends many kilometers away from the control center, the company is looking for a cost-effective wireless solution that can help build a communications backhaul for the compressor stations and network operation center as well as a solution that can help aggregate the data from the field sites.
