The newly introduced WD125 is a small ADVANCED LTE terminal with flexible inputs configuration series device with 4G (LTE Cat 1) network coverage including 3G (UMTS), 2G (GSM) fallback compatibility. The device is equipped with GNSS/Bluetooth and LTE modules, internal GNSS, and LTE antennas.
The device is designed for communication with various third-party RS232 or RS485 devices, like digital fuel sensors (LLS), Garmin navigation devices, RFID readers, and much more. It is also excellent for refrigerated transport because it has an extended input/output set and a 1-wire interface for temperature monitoring.
The Dual-SIM feature provides a backup communication channel where the coverage of a singular operator is not enough. The Dual-SIM feature will also let you significantly reduce roaming costs.
It’s just a small part of the existing functionality but it makes the WD125 even better.
- Reliable 4G (LTE Cat 1) connection with fallback to 3G (UMTS), 2G (GSM) networks
- Double network reliability and multiple network selection
- CAN data reading from vehicles and specialized transport
- Bluetooth for external devices and Low Energy sensors
- RS232/RS485 serial communication interfaces
- 1-Wire® interface to monitor temperature data and RFID/iButton tags
