Collision Avoidance



Mesh4G™ Enabled Architecture technology offers high performance low latency networking solutions that are ideally suited for both near-term and long-term telematics applications.

Now that an agreement on a collision avoidance  wireless standard has been reached, new applications such as motorist safety and traffic management are being developed.

Telematics applications will allow cars to warn other vehicles of nearby emergency situations or adverse road conditions ahead. This information can be displayed within on-board navigation systems and roadside messaging boards in real-time. Drivers can be altered to severe or congested road conditions and provided alternate routes. This will require, reliable low latency networking between moving vehicles and between vehicles and roadside access points.

The collision avoidance protocols have now been determined but require an infrastructure to communicate with other vehicles and central navigation systems to provide Green Wave technology and environmental information such as the speed to travel to the next traffic light and arrive on a green signal.

Mesh4G™’s self-forming and self-healing routing and automatic node discovery allows mesh enabled vehicles to form instant vehicle-to-vehicle (i.e. peer-to-peer) ad-hoc networks and communicate among themselves. Furthermore, Mesh4G™ Multi-Hopping™ routing turns every vehicle into a router/repeater, improving network coverage, reliability and throughput. This enables messages to “hop” though other vehicles. This works to increase end-to-end communications range and enables information to quickly reach all effected vehicles. Unlike other ad hoc solutions, Mesh4G™ technology is highly scalable, supporting dozens, even hundreds of cars per ad hoc group at any given time.

Continuous Meshing™ capabilities are another unique and important feature of  Mesh4G™ networking. It supports seamless networking of roadside infrastructure and mobile ad hoc clusters of vehicles. Mobile nodes, cars in this case, can move seamlessly between infrastructure-based and vehicle-based peer-to-peer networks. This is essential for instant association and disassociation with roadside access points and other mesh enabled highway infrastructure such as variable message signs or sensors.

Mesh4G™ technology can also add position location determination to select radio platforms. Both absolute (geo-referenced coordinates) as well as relative (distance from other nodes) position can be determined and displayed. This information is available in real time to each user, as well as to a network operations center. These position location capabilities are currently deployed using Mesh4G™ QCMR mobile radio.
