LoRaWAN in ski resorts
LoRaWAN technology makes it possible to monitor every aspect of a ski resort in real time — from snow conditions to lift safety — using battery-powered sensors that communicate over distances of several kilometers without any cabling. In mountain environments, where running power and network connections to elevation is costly and maintenance is difficult, it is the most suitable IoT technology available.
What LoRaWAN is and why it works in the mountains
LoRaWAN (Long Range Wide Area Network) is a wireless communication protocol designed for the Internet of Things (IoT). It enables small sensors to transmit data over distances exceeding 15 km in open terrain, with minimal power consumption: a LoRaWAN device can operate for years on a single battery.
The technology uses license-free frequencies (868 MHz in Europe). Data travels from sensors to gateways, which forward it to a cloud server or on-premises server. The architecture is simple and robust — well suited to environments where extreme weather and long distances challenge other wireless technologies.
Advantages and limitations
| Aspect | LoRaWAN |
|---|---|
| Coverage | Over 15 km in open terrain per gateway |
| Power | Battery or solar panel — years of autonomy |
| Operating costs | License-free frequencies, no monthly fees |
| Scalability | New sensors added without changes to the infrastructure |
| Limitations | Not suitable for continuous data streams or video |
The protocol is optimized for the periodic transmission of small data packets — sensor readings every few minutes or hours. It is not suitable for applications that require continuous transmission of large volumes of data or video streams.
Monitoring chairlifts and cable cars
Sensors installed on pylons and load-bearing structures continuously detect abnormal vibrations, oscillations, and structural stress:
- Accelerometers identify out-of-spec vibrations that may indicate problems with bearings or cables.
- Temperature sensors detect overheating in mechanical components.
- Inclinometers measure changes in the alignment of load-bearing structures.
- Load cells verify correct weight distribution.
When a parameter exceeds the safety thresholds, the system immediately sends an alert to the control center. Maintenance interventions become targeted, before failures occur.
Weather stations and environmental monitoring
Solar-powered LoRaWAN weather stations can be placed anywhere in the resort without electrical or network cabling.
Snow sensors measure the height, density, and temperature of the snowpack at multiple depths — data that is essential for avalanche risk assessment, planning artificial snowmaking, and deciding which runs to open. Stations include anemometers, thermometers, hygrometers, barometers, and rain gauges.
The network extends beyond weather stations: air quality sensors measure CO2 levels in high-traffic areas, and UV sensors record solar radiation. All data flows to the central system in real time.
People counting and crowd management
Optical or thermal sensors at lift base and summit stations count the number of skiers transported, identifying peak usage periods and wait times.
Integration with RFID readers at turnstiles completes the picture: every ski pass contains a chip read at the gate, and the data — anonymized — reaches the control center over the LoRaWAN network. Resort managers can see the distribution of skiers across the resort, the most-used routes, and dwell times on runs, and can optimize lift operations and anticipate crowding.
Emergency systems over LoRaWAN
Gondola cabins can be fitted with battery-integrated PA modules: they receive the activation command over LoRaWAN and play pre-recorded emergency messages stored locally, even when main power is interrupted. The control center can broadcast warnings to cabin occupants during critical situations.
For avalanche safety, sensors distributed across the terrain measure snow temperature, ground vibrations, and snowpack movement. When parameters indicate elevated risk, the system triggers alerts and evacuation procedures. Rescue personnel equipped with LoRaWAN devices can be located in real time during search operations.
Snowmaking
LoRaWAN sensors measure air temperature and humidity at multiple points across the resort and identify when and where to activate snow guns to maximize energy efficiency.
Pressure and flow sensors on snowmaking systems detect leaks or malfunctions; energy meters keep operating costs under control. Integration with weather forecasts allows snow production to be planned during the most favorable conditions, reducing water and energy waste.
Snowcat tracking
Snowcats equipped with LoRaWAN locators provide full visibility into slope-grooming operations: routes covered, operating hours, fuel consumption, and engine parameters. This data makes it possible to optimize grooming routes, reduce consumption, and plan preventive maintenance.
Real-time location tracking increases operator safety, particularly during night operations or in low-visibility conditions.
Data integration
The value of an IoT system comes from integrating all collected data. A single web interface shows the status of the entire resort in real time; APIs allow integration with existing SCADA systems, preserving prior investments.
Intelligent alerting filters the information, surfacing only the situations that require immediate attention. Centralized management allows a single operator to monitor the entire resort, and automated reports give managers aggregated data for long-term decisions.
Teleproject designs and builds complete LoRaWAN networks for ski resorts — from radio coverage to sensor supply and configuration, through to integration with existing systems and ongoing technical support.
Frequently asked questions
How many gateways are needed to cover a ski resort?
It depends on the terrain: in open areas a single gateway covers over 15 km, but valleys and ridges require careful radio coverage design. A mid-size resort can typically be covered with a small number of gateways placed at strategic points, identified during a site survey.
How long do sensor batteries last?
Between two and ten years, depending on transmission frequency and environmental conditions. Sensors transmitting readings every 15–30 minutes achieve the longest battery life; weather stations are solar-powered and require no battery replacement.
Can LoRaWAN replace the resort's DMR or TETRA radio network?
No — they are complementary technologies. LoRaWAN carries sensor data; DMR and TETRA radio networks handle voice communications between operators. A complete resort integrates both, often sharing the same installation sites.
What happens if power is interrupted?
Sensors run on battery and continue transmitting. Gateways can be equipped with backup power, and the emergency modules in gondola cabins play pre-recorded messages even without main power.
