IoT Predictive-Maintenance Connectivity
Overview
Vibration, temperature, and current sensors on plant and building equipment feed an edge device that runs analytics locally and forwards results over cellular. The router and gateway carry the data to a maintenance platform, so failures are predicted from live condition data instead of found after a breakdown.
Challenges
- Condition data never leaves the equipment room
- Edge analytics devices need a reliable uplink
- Unplanned breakdowns are costly and disruptive
- Sensors use varied industrial interfaces
Benefits
- Cellular uplink for edge analytics devices
- Live condition data to a maintenance platform
- Predicted failures instead of reactive repairs
- Industrial interfaces bridged at the gateway
Recommended Products

RUT956
The RUT956 is a 4G LTE Cat 4 industrial router with dual SIM for automatic failover and four Ethernet ports. OpenVPN, IPsec, and DMVPN secure remote sites, and dual SIM keeps fixed installations and machine-to-machine links online when one network drops.
- CONNECTIVITY - 4G LTE (Cat 4), 3G, 2G
- DUAL SIM - With auto failover, backup WAN and other switching scenarios
- MULTIPLE INTERFACES - Ethernet, Serial (RS232, RS485) and multiple Inputs/Outputs
Teltonika Networks

TRB256
For endpoints that send little and must last, the TRB256 runs LTE Cat M1 and NB-IoT, including the 450 MHz band. Dual SIM, Ethernet, serial and I/O all terminate on a 16-pin terminal block.
- CONNECTIVITY - 4G/LTE Cat M1/Cat NB1, NB2/EGPRS
- DUAL SIM - Auto-failover, backup WAN, and more switching scenarios
- INTERFACES - Ethernet, I/Os, and Serial (RS232, RS485) interfaces with 16-pin terminal block

TRB236
The 450 MHz band reaches where ordinary cellular does not, which is why utilities and critical-infrastructure networks run on it — and the TRB236 is 450connect certified for it. Dual SIM, RS232/RS485, Ethernet and digital I/O terminate on a terminal block.
- LTE 450 - Extend coverage and signal reliability in utilities sector using the 450 MHz band
