Background
As we transform into the digital smart city era, Intelligent Transport System (ITS) becomes an indispensable component. ITS technologies help cities manage traffic flow, idle vehicle time, congestion relief, and lower emission from reduction of idling and sitting in traffic. Many cities have implemented some upgrades including wireless networks, connected streetlights, surveillance cameras, to improve their existing infrastructures and further enhance capabilities and efficiency.
The backbone of an intelligent traffic management system is wireless connectivity, from 4G, 5G, low power wide area network (LPWAN) to fiber, in order to cater to the various end use applications that require different types of networks. As a safety-critical system, ITS requires redundant backup solutions to ensure reliable data transmission and uninterrupted connectivity.
Requirements
To implement a secure intelligent transportation management system requires a combination of connectivity, hardware, and software technologies to work together as one system. A global leader of intelligent traffic systems was seeking for turnkey system for their ITS solution. The joined smart solution meet the following requirements:
- 5G connectivity with Micro-SIM & 1x eSIM, 5G technology can enable real time data collection and analysis in an intelligent traffic system without latency, and multi-SIM selection ensures that operators resources are used most efficiently.
- PoE+ IEEE 802.3 af/at, The power delivery over Ethernet function allows to connect IP Camera for video surveillance and get real time traffic image from road-site for further analysis.
- Rugged and IP67 waterproof for outdoor environment, Full IP67-rated extruded aluminum and heavy-duty steel case that offers complete protection from water submersion and harmful dust particles for use in a variety of severe environment projects.
- Isolated I/O and wide range power input, NCR-1567 is designed for enabling to function in harsh environments with isolated I/O and power protection. Supports wide range power input: DC 9~50V (covered 12/24/36V).
Solution
Intelligent traffic systems may be in different development stages globally, but integrators have recognized that a single source of Internet connectivity is insufficient, especially with the high maintenance costs due to unreliable availability. Lanner’s NCR-1567 rugged gateway with 5G and micro SIM functionality is designed to provide backup cellular connectivity for intelligent traffic management infrastructure because it is reliable and secure. Indeed, operators are more motivated to offer attractive data service plans for large scale projects compatible with carrier aggregation technology, and backup SIM functionality can further provide uninterrupted connectivity by switching to a redundant operator service as needed. NCR-1567 is IP67-rated with isolated I/O and power protection for usage in demanding environments and critical infrastructure.
