4G LTE Mobile IoT Gateway

The CR3158 provides a reliable 4G/LTE connection for transferring machine data to remote systems and cloud platforms. It supports LTE Cat-4 as well as GSM, GPRS, EDGE, UMTS and HSPA networks for broader cellular compatibility. The integrated eSIM simplifies cellular connectivity and device deployment. Machine information can be transmitted remotely for monitoring, service and data collection applications. The gateway can automatically use available mobile networks according to the supported network technology. This makes the CR3158 suitable for connected-machine and fleet-management solutions.

CAN Communication and Machine Integration

The CR3158 provides three CAN interfaces for connection to mobile-machine control systems and electronic control units. CAN 2.0 A/B communication according to ISO 11898 is supported, with CAN2 electrically isolated. Machine parameters and CAN process data can be transmitted through the mobile IoT connection. The device can also provide wireless CAN access through its WLAN and Bluetooth interfaces. CAN-to-CAN wireless bridging is supported for applications where physical CAN cabling is inconvenient. This allows the gateway to integrate with existing CAN-based machine architectures without major system changes.

GNSS Positioning and Machine Monitoring

The integrated GNSS receiver allows the CR3158 to acquire machine position information. It supports GPS, GLONASS and BeiDou satellite systems, with two navigation systems capable of being evaluated simultaneously. Position information can be transferred through the CAN interface or sent through the mobile network. This enables machine tracking, fleet monitoring and location-based service functions. The device also includes acceleration and yaw-rate measurement capabilities for additional machine-motion information. These features make the gateway suitable for advanced telematics and remote-monitoring applications.

WLAN and Bluetooth Connectivity

The CR3158 supports WLAN and Bluetooth communication in addition to cellular connectivity. WLAN supports IEEE 802.11 a/b/g/n operation in the 2.4 GHz and 5 GHz bands. Bluetooth supports Bluetooth Classic and Bluetooth Low Energy for wireless CAN data exchange and service access. The device can operate in WLAN infrastructure mode or mini access-point mode. It can also function as a CAN-Bluetooth/WLAN interface or bridge. This provides flexible local communication options for commissioning, diagnostics and machine maintenance.

Real-Time Data and Cloud Logging

The CR3158 supports both real-time mode and cloud logging mode for mobile IoT communication. In real-time mode, CAN data and other machine information can be transmitted and received continuously. Cloud logging mode allows data to be stored and transmitted to the mobile IoT platform for remote analysis. The device can buffer data when the cellular connection becomes unstable. This helps reduce data loss during temporary communication interruptions. Secure TLS end-to-end communication provides an additional layer of protection for cloud-based data transmission.
