Remote IoT in No‑Signal Areas: Satellite vs Cellular Connectivity Explained

Imagine agriculture sensors silent in vast no-signal fields, mining trucks offline across deserts, logistics assets lost at sea – remote monitoring demands connectivity that works everywhere. Cellular networks (including NB-IoT, LTE-M) and private options like LoRaWAN dominate urban zones where infrastructure exists, yet both fail in true no-signal zones. Satellite IoT delivers global reach, low power, and scalability. This guide breaks down the differences to help you pick the right fit.

Coverage Comparison

Cellular & terrestrial: Rely entirely on ground-based towers and gateways, providing excellent service in densely populated urban or networked areas but delivering patchy or zero coverage in rural expanses, mountainous terrains, remote islands, or open seas. While LoRaWAN extends 5-15km from gateways for rural farms or mines, it requires installing/positioning gateways – impractical across vast fields, oceans, or mobile assets with no backhaul. This limitation becomes critical for remote monitoring, where assets in off-grid communities or deserts need constant oversight without human intervention.

Satellite: Offers truly global coverage encompassing 85% of the Earth’s surface lacking cellular towers, including polar regions, oceans, and infrastructure-poor zones. Devices connect directly to orbiting satellites, bypassing the need for local repeaters. This means seamless data relay from sensors to cloud dashboards, regardless of location – ensuring operators spot issues like underperformance or faults weeks before they escalate.

Cost Breakdown

Cellular & terrestrial: Remains cost-effective due to leveraging existing tower infrastructure, with low per-device fees for high-volume deployments. However, extending coverage to remote sites skyrockets expenses through new tower installations, cabling, or private LoRaWAN networks, often making it impractical for sparse or mobile assets.

Satellite: Providers like Myriota deliver low monthly data costs optimised for small, infrequent bursts – ideal for remote monitoring where you transmit only critical alerts (e.g., power output drops or fault codes) rather than continuous streams. No infrastructure overhead means massive savings at scale; for fleets across regions, satellite becomes cheaper long-term.

Power Efficiency

Cellular & terrestrial: IoT devices face power challenges in remote setups. Roaming between towers or operating far from the nearest base station spikes consumption, leading to unpredictable battery life – even fixed installations drain faster in weak signal areas. Servicing batteries in harsh, inaccessible spots adds operational headaches and costs.

Satellite: Myriota’s UltraLite network protocol revolutionises this, allowing off-the-shelf AA batteries to last 5-10 years through ultra-efficient, short transmissions triggered only when satellites pass overhead. Bi-directional communication adds value: Cloud commands can reconfigure devices, adjust reporting frequency, or toggle systems remotely – you might reduce updates during some periods to extend life further. HyperPulse adds lower latency, higher daily data allowances, and 5G NTN standards compliance for applications needing more frequent reporting, complementing UltraLite’s extreme efficiency.

Other Key Factors

Reliability: Satellite IoT excels in extreme weather, dust storms, or rugged terrains where terrestrial signals fade. Conversely, terrestrial networks perform reliably in dense urban or regional areas with stable coverage. Myriota’s secure satellite pathways ensure data integrity from sensor to cloud – vital for preventing operational downtime or asset failures regardless of location.

Latency: Terrestrial IoT delivers near-instant responses where infrastructure exists. Satellite suits tolerant apps like trending – UltraLite multiple daily reports at low cost, while HyperPulse lower latency nearing real-time.

Flexibility: Both satellite and terrestrial IoT support bi-directional communication and remote device reconfiguration. A hybrid approach can combine their strengths – leveraging terrestrial where coverage is dense and satellite for always-on global reach.
