思科、NXP联手投资Cohda wireless 助推车联网

据了解，Cohda Wireless制造的硬件设备可以让汽车变得更智能、更具连接性。其技术可以让汽车之间以及汽车与设施(如红绿灯)之间搭建起无线通讯系统，从而共同营造出一个更加安全的行车环境。Cohda的技术可以打造出更加动态和敏感的安全体系，从而帮助减少事故的数量。以期在物联网市场占得先机，思科和NXP宣布对汽车无线通信设备制造商Cohda Wireless进行一项战略投资。

Car-to-Car (C2C) and Car-to-Infrastructure (C2I) communications enable active safety systems that can affect 81 percent* of all crash scenarios, as a result helping to reduce fatalities and injuries on the roads. In addition to improving safety, car-to-infrastructure (C2I) communication holds great potential for intelligent transport system (ITS) management and reducing greenhouse gas emissions from vehicles.

This progress in traffic management and road safety can be realized with the help of applications that warn of hazards such as the potential of a collision ahead, alerting if a nearby vehicle is losing control, or of upcoming traffic congestion, and others – all enabled by the combined expertise and technologies of the three companies.

By allowing vehicles to reliably interact with each other when travelling at high-speeds, each vehicle can give drivers warnings about potential hazards and allow them to avoid accidents, or even automatically respond to changing driving conditions faster than typical human reaction times. Warnings about traffic blockages ahead also allow early re-routing to avoid traffic congestion.

C2C and C2I communications require highly reliable and secure data exchange between fast moving vehicles and infrastructure in a range of conditions – from rural highway to dense urban canyons. NXP and Cohda Wireless have built a market-ready, flexible wireless communication solution for onboard-units based on Cohda’s existing advanced radio and NXP’s market-proven software-defined radio technology. This makes it a key element to connect to Cisco’s vision of a ubiquitous and highly-secure Internet of Everything.

Onboard and road side units developed using technologies from the three companies have been tested to global standards in major field trials. In August 2012, the “Safety Pilot Model Deployment” trial by the US Department of Transport was initiated, and other major field trials include simTD in Germany, ScoreF in France, and ERP2 in Singapore.

The three companies will apply their collective expertise and technologies to help automotive OEMs, suppliers, enterprises and consumers to connect vehicles with ITS infrastructure. This will be spearheaded by producing the first automotive-qualified IEEE 802.11p products for onboard and road side units that are ready for C2C and C2I deployments across the globe.

目前Cohda已经跟欧洲的12家汽车制造商进行合作，计划在2015年在相关厂家的汽车上安装此项技术。在美国底特律也正在跟8家制造商进行测试。
