1. What a care device sends
Smart elderly care covers monitoring, health readings, an emergency call, and fall detection. Wristbands, emergency buttons, and vital-sign monitors report over 4G or NB-IoT. A geofence raises a wandering alert and can limit the area a person is expected to stay in. SOS is a one-press call that reaches family and the care station. Fall detection uses an accelerometer and an algorithm to spot an abnormal posture. Care homes and home care usually need watching around the clock, so the link has to stay up. SimtoLink gives care providers 4G and NB-IoT, a shared data pool, VPDN, and an API into the care platform.
2. Location, vital signs, SOS, and a fall
A wandering alert, a blood-pressure reading, and an SOS do not ask the same thing of the link. The SOS has to leave in seconds. A sleep summary can wait.
Location and the geofence
Wristbands and positioning terminals send location and activity over 4G, for a geofence and a wandering alert.
Vital signs
Blood-pressure monitors, glucose meters, and sleep monitors report over 4G, for chronic-disease management and an alert when a reading is out of range.
Emergency call and SOS
Emergency buttons and SOS wristbands send the alarm over 4G as it happens, for a one-press call and a notice to the family.
Falls
Fall detectors and behavior sensors report over 4G, for a fall alert and a flag when behavior looks wrong.
3. What the care link has to do
- Around the clock: Monitoring and emergency calls have to stay online. An SOS and a fall alert need a response measured in seconds.
- The alarm goes first: An SOS button and a fall detection have to be reported at the highest priority, so family and the care station can respond.
- Location and the geofence: Wristbands and positioning terminals send location, for an alert when someone crosses the fence and when someone is missing.
- Health and privacy: Vital signs are private. They need a VPDN private network and TLS, in line with care-sector rules.
- Different devices: A wristband needs 4G for live location and a call. An emergency button or a fall detector can use NB-IoT, which costs less and lasts longer on a battery.
4. Which SIM fits which care device
A wristband and a fall detector do not need the same radio. The table is a starting point:
| Use | Recommended network | Why it fits |
|---|---|---|
| Wristbands and positioning terminals | 4G | Live location, a geofence, and a call |
| Emergency button, SOS | NB-IoT / 4G | One-press call. NB-IoT costs less and lasts longer; 4G answers faster |
| Fall detection, motion sensors | NB-IoT | Infrequent alarm reports, low cost, long battery life |
| Health readings, blood pressure and glucose | 4G | Vital signs, chronic-disease management |
5. How much data a care device uses
One device typically uses about 20–100MB a month. Pool SIMs by device type, keep 20%–30% spare, and use VPDN so health data stays private.
6. Security and compliance
Health and privacy are in scope. Treat this as the highest security level. A VPDN private network, TLS, and an IP allowlist are required. SimtoLink provides financial-grade protection and completes real-name registration for the SIMs.
7. What SimtoLink would deploy
For wristbands and video monitoring, use a 4G IoT SIM. For emergency buttons, fall detectors, and environmental sensors, use NB-IoT. A wristband has to report location and place a call as they happen. A button has to last a long time on a small battery. SimtoLink plans for 99.9% network availability, a shared data pool, and an API into the care or health-management platform.
8. Putting care devices in
Rollout:
Size the plan to the device, and check coverage where people actually live. Set VPDN and the APN, plus an IP allowlist, and alert at 80% of the data allowance. SimtoLink stays with the project from the first wristband through the wider care network. Contact us for a plan built around those sites.
