At Vision link, we use LoRa (Long Range) radio technology at the heart of our remote monitoring systems to deliver secure, reliable, and energy-efficient data transmission from our intelligent battery-powered sensors to our gateways.

LoRa enables our systems to operate effectively in remote, hard-to-reach, and off-grid locations, providing long-range connectivity while keeping power consumption exceptionally low. This means our sensors can operate for years on standard, user-replaceable batteries — reducing maintenance costs and maximising uptime.

How LoRa Works for Our Customers

Our LoRa-enabled sensors transmit data using chirp spread spectrum modulation, which offers exceptional signal penetration and noise resilience. Whether installed in rural landscapes, around coastal infrastructure, or across large industrial sites, our devices maintain a strong, stable connection to the gateway.

From there, the gateway uploads sensor readings via 4G/LTE or NB-IoT to our secure web portal and smartphone apps, giving you real-time access to critical environmental and structural data.

Why We Chose LoRa Technology

• Long Range – Our LoRa-based systems can cover up to 1 mile line-of-sight for local sensor-to-gateway links.

• Ultra-Low Power – Sensors run for years without battery replacement.

• Robust & Reliable – Strong performance even in challenging terrains, behind structures, or through vegetation.

• Secure – Fully acknowledged, military-grade two-way communication ensures data integrity.

• Scalable – One gateway can handle dozens of sensors for cost-effective deployment.

Real-World Applications

Our LoRa-powered solutions are deployed across industries for:

• Water Level Monitoring – Dams, rivers, flood risk zones, and coastal defences.

• Temperature & Humidity Tracking – Agriculture, storage facilities, and climate-sensitive operations.

• Structural Movement Detection – Bridges, earth banks, retaining walls, and construction sites.

• Vibration & Impact Monitoring – Machinery health, landslide detection, and security applications.

• Environmental Compliance – PM2.5 and PM10 air quality monitoring for industrial and urban sites.

LoRa Integration in Our Systems

By integrating LoRa into our solar-assisted, battery-powered gateways, we ensure that even the most isolated sensors can report back without requiring expensive cabling or on-site networking. All data is timestamped, securely transmitted, and stored for historical analysis, helping you make faster, more informed decisions.
