OKI developed mobile phone inter vehicle communication systems based on DSRC

Oki Electric has developed Dedicated Short Range Communications (DSRC) inter-vehicle communication attachment for mobile phones to enable pedestrian and vehicle communication. By plugging in the safety mobile phone attachment to mobile phones, pedestrians can exchange location information with vehicles with inter-vehicle communication system.

The "Safety Mobile Phone Attachment" was developed based on the Safety Mobile Phone system. It is compatible with Global Positioning System (GPS) technology and can send positioning data via DSRC. When the attachment receives a DSRC data packet from a vehicle, it will transmit the information to the mobile phone via Universal Asynchronous Receiver Transmitter (UART). Likewise, by sending commands to the attachment via UART, mobile phones can transmit specific DSRC packet information. Thus, by connecting the attachment to an external device that has a UART interface, such as a mobile phone, users can develop applications on that platform.

The attachment also packs an acceleration sensor and a magnetic sensor, which enables users to develop, improved positioning performance such as to supplement GPS positioning or inertial navigation.

OKI has prevented radio attenuation caused by the human body by providing two antennas (one in front of the body and the other one behind the body) are provided.

By using this product, a pedestrian will notify nearby vehicles of his or her location and obtain their location through the DSRC inter-vehicle communication function. In addition, the attachment and phone can alert the users beforehand when the positioning of the person and vehicle may lead to a traffic accident. This technology will contribute to Japan's "Inter communication system for pedestrians, roads and vehicles" under the "New IT Reform Strategy," which will start from the fiscal year ending March 2011, and will contribute to reducing accidents for the vulnerable road users.

As next step OKI plans to include UHF band inter-vehicle communication functionality, expand to IEEE802.11p capability and develop modules that can be incorporated in 3G mobile phones.
