Oki Electric Industry Co., Ltd. has succeeded in developing the world's first ultra small DSRC (Dedicated Short Range Communication) wireless module for embedding in mobile phones to be used for DSRC inter-vehicle communication systems. Using this module based on an OKI LSI, the company succeeded in trial production of the world's first mobile phone, "Safety Mobile Phone" specifically designed to improve pedestrian safety. The Safety Mobile Phone notifies vehicles in the surrounding area of its location and retrieves the location information of vehicles in the surrounding area that are equipped with the DSRC inter-vehicle communication system. By making it possible to reduce the occurrence of vehicle-pedestrian accidents, the phone contributes to pedestrian safety.

In the future, the phone will be able to instantly analyze the behavior of other parties based on exchanged location information and the passage of time. When there is a possibility that two parties are near collision, pedestrians will be warned through the vibration function on their mobile phones, and drivers will be informed through voice guidance function on the inter-vehicle communication equipment, helping avoid danger for both drivers and pedestrians.
