1. What a library device sends over cellular
A smart library covers self-service borrow and return, seat management, environmental monitoring, and RFID stocktakes. Self-service machines, seat terminals, and the ILS (integrated library system) report over 4G. RFID handles borrow and return, theft prevention, and stocktakes. Seat terminals support reservations and holding a seat. SimtoLink supplies 4G to libraries, with a data pool and an API into the ILS.
2. Circulation, seats, climate, and stocktakes
The floor covers borrow and return, seats, and the room environment. Bandwidth, and how quickly a record has to land, differ by device:
Self-service borrow and return with RFID
Self-service machines and RFID security gates talk to the ILS over 4G, for borrow and return, stocktakes, theft prevention, and data sync.
Seat management and reservations
Seat terminals and reservation displays report occupancy and bookings over 4G, for seat reservations, holding a seat, and analysis.
Environmental monitoring and energy
Temperature, humidity, CO2, and light sensors report over 4G, for climate control, energy saving, and protection of rare books.
Stocktake robots
A stocktake robot reports shelf counts and its location over 4G, for automatic stocktakes and finding misshelved books.
3. What the library link has to cover
- ILS link: Self-service machines and RFID security gates have to stay in sync with the ILS, for borrow and return, stocktakes, theft prevention, and collection sync.
- Seat management: Seat terminals and reservation displays report occupancy and bookings, for reservations, holding a seat, and analysis.
- Climate and rare books: Temperature, humidity, CO2, and light sensors report, for climate control, energy saving, and protection of rare books.
- Stocktakes on the move: Stocktake robots and carts need a link while they move, to report counts and misshelved books.
- Platform link: Connect to the ILS and the smart-library platform, for multi-branch management, statistics, and a closed API loop.
4. Which SIM fits which device
Bandwidth and latency differ by device. Use the table as a starting point:
| Use | Recommended network | Why it fits |
|---|---|---|
| Self-service machines and RFID security gates | 4G | Live ILS link, borrow and return, stocktakes |
| Seat terminals and reservation displays | 4G | Occupancy and booking reports |
| Environmental sensors and stocktake robots | 4G | Climate control, stocktake data, and a link while moving |
5. How much data a library device uses
One device typically uses about 50–200MB a month. Pool SIMs by device type, keep 20%–30% spare, and use a VPDN to keep the link private.
6. Security for collection data
Treat the link as medium security. It needs a VPDN, TLS, and an IP allowlist. SimtoLink provides the VPDN, a private APN, and real-name registration for the SIMs.
7. What SimtoLink would put in the library
For self-service borrow-and-return machines, stocktake carts, and electronic reading terminals, use a 4G IoT SIM. The machines have to stay in sync with the ILS, and the carts need a link while they move. SimtoLink plans for 99.9% network availability, a data pool, and an API into the ILS.
8. Opening the branches
Rollout:
Pick the SIM by device type and check coverage in the target library. Set the VPDN or APN and the IP allowlist, and alert at 80% of the data allowance. SimtoLink stays with the project from the first branch through the wider service. Contact us for a plan built around those floors.
