Every remote site needs a way to get its data home, and the three main choices - cellular, satellite, and licensed radio - each win in different conditions. This guide compares them on coverage, latency, bandwidth, and cost so you can choose the right backhaul, or mix them, for oil and gas telemetry.
Cellular vs Satellite vs Radio in one line: Cellular, satellite, and licensed radio are the three primary ways remote SCADA sites reach the central host: cellular is the low-cost default where towers reach the site, licensed radio suits operator-owned field networks with no airtime cost, and satellite covers sites with no other connectivity at the price of higher latency and cost.
Cellular is usually the first choice where coverage exists: cheap hardware, low latency (tens of milliseconds on LTE), ample bandwidth, and a recurring per-SIM data cost. Its weakness is coverage - no tower, no link - and dependence on a carrier. Licensed radio is an operator-owned network with no airtime cost and strong control, ideal for gathering systems and pipelines, but it carries less bandwidth and means owning and maintaining the infrastructure.
Satellite reaches anywhere the sky is visible, which makes it the backhaul of last resort for remote basins, offshore, and wilderness pipeline segments. Geostationary satellite adds roughly half a second of latency and data is costly; newer low-Earth-orbit services cut latency to tens of milliseconds and improve economics, making satellite viable at more sites and as a failover behind cellular.
The right answer is rarely one technology for a whole fleet. A common pattern is licensed radio as the field backbone tying local sites to a hub, then cellular for the hub's trip to the cloud, with satellite as backup where cellular is unreliable. Sites that must not lose data often carry dual paths - cellular primary, satellite failover - with automatic switchover in the gateway. The decision comes down to what coverage is actually available at each location, the latency and bandwidth the application needs, and the total cost over the asset's life.
Whatever the transport, the payload is the same: the RTU or flow computer's data over a protocol like Modbus, DNP3, IEC 60870, or MQTT. A cloud SCADA such as Merobix reads that data once it arrives, treating cellular, satellite, and radio as interchangeable transport underneath, so operators can pick the best link per site without changing the monitoring platform.
It depends on coverage. Use cellular where a tower reaches the site - it is cheapest and lowest-latency. Use licensed radio if you already run a field radio network. Use satellite where neither reaches, accepting higher latency and cost, often as a failover.
Yes. Dual-path sites commonly run cellular as primary and satellite as failover, with the gateway switching automatically if the primary drops. This keeps critical sites connected even when one transport is unavailable.
No. Cellular, satellite, and radio just carry the same protocol data - Modbus, DNP3, IEC 60870, or MQTT. A cloud SCADA like Merobix reads that data regardless of transport, so you can pick the best link per site without changing the monitoring system.
