1. What a coastal station reports
Smart coast covers coastal monitoring, marine observation, buoy stations, and tide stations. They send hydrology, weather, and water quality over 4G. Coastlines are often remote, and 4G is what covers them. SimtoLink gives marine agencies 4G, a shared data pool, a private APN, and an API into the ocean-observation platform.
2. Tides, buoys, cameras, and ships
A tide reading, a video of the shoreline, and a ship track do not ask the same thing of the link. A rescue position has to go out immediately. A research sample can wait.
Tide stations and water quality
Tide stations and water-quality sensors send tide level, pH, and dissolved oxygen over 4G, for a marine warning and ecological monitoring.
Buoys
Ocean buoys and observation stations send temperature, salinity, current speed, and waves over 4G, for a marine forecast and a research record.
Shoreline cameras
Coastal cameras send video over 4G for shoreline monitoring, a check for illegal fishing, and emergency command.
Ports and ships
Port sensors and ship AIS report over 4G, for port management, a ship track, and navigation safety.
3. What the coastal link has to do
- Coastal and offshore video: Video along the coastline, in ports, and in aquaculture areas needs steady high bandwidth so 24-hour HD pictures do not drop.
- Live ship tracking: Fishing boats and cargo ships keep reporting AIS position, for track playback, boundary alerts, and rescue location.
- Marine environment monitoring: Water quality, waves, and weather sensors are collected live, for warnings and for judging a coming hazard.
- Communications at sea: Search-and-rescue and communication gear need a highly reliable link. A satellite-4G hybrid network extends coverage offshore.
- Private-network isolation: Coastal infrastructure needs a private APN so it cannot be reached from outside, in line with maritime safety rules.
4. Which SIM fits which station
A buoy and a coastal radar do not ask the same thing of the radio. The table is a starting point:
| Use | Recommended network | Why it fits |
|---|---|---|
| Coastal surveillance / radar detection equipment | 4G/5G | Video backhaul, ship identification, safety alerts |
| Fishing boats / shipboard communication terminals | 4G+satellite | Position tracking, communications, catch records |
| Marine environment monitoring buoys | NB-IoT/4G | Water quality and weather collection, low power, long life |
5. How much data a station uses
One device typically uses about 100–500MB a month, mostly video and images. Pool SIMs by device type, keep 20%–30% spare, and use a private APN to keep the link closed.
6. Security and compliance
Treat this as medium security. Sessions need TLS/SSL, a private APN, and an IP allowlist. SimtoLink completes real-name registration for the SIMs.
7. What SimtoLink would deploy
For ocean monitoring, use a 4G IoT SIM on buoys, shore-based radar, and fishing-boat terminals. Nearshore monitoring needs a stable link, and a fishing boat needs more than one operator so coverage holds at sea. SimtoLink plans for 99.9% network availability, multi-operator selection, a shared data pool, and an API into the ocean-monitoring platform.
8. Taking a station to sea
Rollout:
Size the plan to the device, and check coverage on the coast and offshore. Set the APN and an IP allowlist, and alert at 80% of the data allowance. SimtoLink stays with the project from the shore trial through daily operations. Contact us for a plan built around that coastline.
