1. What a weather network connects
Smart weather monitoring covers weather stations, environmental monitoring, and warning systems. Temperature, humidity, pressure, wind speed, and precipitation go up over 4G or NB-IoT. The six elements are temperature, humidity, pressure, wind, precipitation, and sunshine. Soil moisture feeds irrigation decisions. Stations often sit in open country or on mountains, so 4G and NB-IoT are what hold coverage. SimtoLink provides 4G and NB-IoT for meteorology, environmental protection, and agricultural companies, with a shared data pool, VPDN, and an API into the weather platform.
2. Stations and what each one sends
Weather stations, environmental monitoring, and warnings do not ask for the same bandwidth or the same power budget:
Weather stations and the six elements
A weather station sends temperature, humidity, pressure, wind speed, precipitation, and sunshine over 4G or NB-IoT for forecasts and climate analysis.
Agricultural weather and environmental monitoring
Agrometeorological stations and soil-moisture stations report over 4G for farming decisions, irrigation guidance, and hazard warnings.
Hazard warnings and response
Warning terminals send rainfall, water level, and geological-hazard data over 4G for flood control and geological-hazard warnings.
Weather service for an industry
Stations serving transport, power, and aviation report over 4G so those sectors get a weather service built for their work.
3. What the connection has to deliver
- Field coverage: Stations sit in open country, on mountains, and on islands, usually with no wired network. 4G and NB-IoT hold coverage. You need multi-operator network selection.
- Six elements and warnings: Temperature, humidity, pressure, wind, precipitation, and sunshine go up on a schedule. Hazard warnings and flood alerts have to go out in time.
- Agriculture and industry: Agricultural weather and soil moisture support farming decisions. Transport, power, and aviation need a weather service built for that sector.
- Low power and a long battery life: A remote site can take NB-IoT when cost has to stay low and the battery has to last. Automatic weather stations and radar need 4G bandwidth.
- Platform link: Connect the weather, environmental-protection, and agriculture platforms. The API closes the data loop.
4. Which IoT SIM card to choose
Bandwidth and power differ by device and by where it sits. Weigh both before you order. The table is a starting point for a typical station:
| Use case | Recommended radio | What matters |
|---|---|---|
| Automatic weather stations, six elements | 4G | Temperature, humidity, pressure, wind, precipitation, sunshine, scheduled reports |
| Temperature, humidity, and rainfall sensors | NB-IoT | Infrequent reports, low cost, long battery life |
| Radar, video | 4G | Observations, video backhaul, high bandwidth |
| Agricultural weather, soil moisture | 4G | Farming decisions, irrigation guidance |
5. Data use
About 20–100MB a month per device. NB-IoT sites sit below that. Pool by device type, keep 20%–30% spare, and use VPDN to keep the link private.
6. Security and compliance
The security level is medium. You need a VPDN private network, TLS, and an IP allowlist. SimtoLink supplies VPDN, a dedicated APN, and real-name registration together.
7. What SimtoLink recommends
For weather monitoring, use 4G IoT SIM cards on automatic weather stations, radar, and video, or NB-IoT on infrequent sensors such as temperature, humidity, and rainfall. Stations often sit in remote country and need multi-operator network selection. You get 99.9% network availability, a shared data pool, and an API into the weather platform.
8. How to roll it out
Bring a weather network onto IoT connectivity in this order:
Choose 4G or NB-IoT by device type, prove coverage in the target area, set VPDN and APN with an allowlist, and alert at 80% of the plan. SimtoLink can run the work from survey to go-live. Ask for a plan written for those stations.
