Product Overview and Engineering Role
The SimtoLink GPS logistics tracking tag is for line-haul, high-value cargo, and rented equipment. Outdoors it fixes by satellite. In a warehouse or on a dock, a short-range link such as Bluetooth can close the handover. Temperature and humidity fields are there as evidence of the trip.
Cellular or NB-IoT backhaul, the report interval, and the geofence follow the order code and the Hardware Specification. SimtoLink can supply a template for a TMS or a customs-supervision platform.
Reliability and Site Conditions
The wide temperature range and vibration rating suit a strap-down on a trailer or a pallet. A metal body can block both GNSS and the radio, so prove the mounting spot on a loaded vehicle.
SimtoLink recommends a low-battery alarm and a tamper alarm, and a log of SIM or eSIM life and the tariff plan.
Key Hardware Parameters
The table is the typical configuration of this tag, for selection and for bid clauses. A custom band, package, or batch UID is available from SimtoLink with the Hardware Specification and the Installation and Commissioning Guide. Order codes in the family can differ slightly; the nameplate and the documents shipped with the tag govern.
| Parameter | Specification | Notes |
|---|---|---|
| Band | 2.402～2.480 GHz | Region code |
| Read range | 0～150 m LoRa | Depends on the antenna |
| Memory | EPC 96 bit | Lockable write |
| Ingress protection | IP54 | On-metal construction |
| Battery | Passive | 3–5 year life |
| Sensing | Temperature and humidity | Sample interval configurable |
| Communications | BLE 5.2 | Encrypted |
| Mounting | Rivet | Metal surface |
| Operating temperature | -36～81 ℃ | Cold chain optional |
| Standards | EPCglobal | Interoperable |
Typical Deployments
Four layouts that come up when you size a tracking tag and look at payback:
Reefer trucks
Track and the temperature and humidity curve are kept as evidence.
Cross-border containers
Geofence enter and exit, plus a policy for an abnormal open.
Two-wheeler rental
Cell-tower assist when the canyon blocks GPS.
Dock handover
A Bluetooth handshake on the dock moves responsibility.
Installation, Grounding, and Maintenance
- Point the GNSS antenna up, away from metal shields and heat. In a trailer, prefer a window or an external antenna, by model.
- After a rivet or a strap, pull-test the tag so vibration does not throw it off.
- Set the report rate to the local rules, so it does not interfere with driving or create a privacy problem.
- Recheck SIM expiry, the data cap, and roaming three months ahead.
- Wipe data on a retired tag, and recycle the battery to the rules.
Ordering, Documentation, and Support
SimtoLink supplies the hardware specification, dimension drawings, a wiring table, and a sample project for this tag. Volume orders can include a sample review and a factory inspection. Warranty and calibration follow the contract and the documents shipped with the unit.
