In-vehicle Wireless Solution

Overview

In this highly digital era, transportation operators are constantly challenged in data collection, analysis and management in real time from various existed and new digital systems. Providing modern services improved by digital in transportation not only improves operation efficiency, but also attracts people to take more public transportation.

The integration of 5G connectivity facilitates real-time decision-making for control centers and drivers to issue instructions promptly based on current situations. This technology also allows maintenance personnel to diagnose and repair faults remotely, providing them with ample information about the condition of the rail system and its surrounding environment through monitoring systems. With access to comprehensive information, any sudden emergencies can be addressed promptly, achieving tasks such as anomaly detection, ensuring safe transportation, slope monitoring, and rainfall detection. This seamless integration of various information sources aids in inspection, maintenance, and equipment updates, reducing human errors and enhancing operational efficiency and railway safety.  

Z-COM In-vehicle Wireless Solution is integrated with different wireless AIoT gateways , controllers together with indoor and outdoor Access Points to offer data access from 4G/5G, Wi-Fi,GPS/GNSS, etc.. The products offer a wide range of interfaces, with robust wireless connectivity and reliability, for operators to create a complete wireless service and management portfolio from vehicle cabins inside, the platforms, to the entire railway station.

Anticipating potential risks, Z-COM has optimized rail detection functionalities. Z-COM’s 5G NR gateway, which has passed EMC requirements under both EN 50121 and EN 50155 railway standards, facilitates high-definition image feedback from trackside and between trains, as well as passenger safety monitoring inside train carriages. It demonstrates the high throughput and low latency characteristics of 5G, complemented by IoT sensors for perimeter detection around the tracks. This automated warning system reduces the burden of manual inspection operations, alerts to foreign objects on the tracks and enhances level crossing safety. By addressing current shortcomings, Z-COM’s solution effectively safeguards train operations' safety.
