How much does it cost for full service data quality control, state of health monitoring, and maintenance?

Depending on various factors such as location, data rate, required response time for outages, and others, the quarterly charge can vary significantly per site.  However, there is an economy of scale with larger networks to decrease the average station cost.  For full-service SOH/QC/O&M, the station is visited every 2 years whether or not the data indicates an issue, regardless of access or location.  This is done to conduct preventative maintenance and/or vegetation removal and to maintain contact with the equipment hosts if applicable.
