3G Cellular Networks Come Through For Oil, Gas SCADA Applications
Cellular telephone networking has emerged as a strong contender for oil and gas SCADA system communications. 3G cellular networks are widely installed even in remote areas. Data plans for SCADA applications are competitive. Industrial 3G modems are commonly available, proven and have been integrated in some RTU models. Tight integration of 3G modems in RTU products reduces purchase costs and mitigates risks in terms of start-up, operation and maintenance. Cellular Networks – A Brief Review A quick review of cellular evolution shows that earlier “1G” and “2G” technologies presented drawbacks that made them less attractive than competing technologie
