Peer-to-peer Wi-Fi links are being used by General Motors researchers to build a car-based system that can detect pedestrians and cyclists carrying Wi-Fi equipped smartphones or sensors on crowded or poorly visible streets, and then alert drivers. By eliminating a cell tower or access point, the peer-to-peer technology (based on the Wi-Fi Alliance’s Wi-Fi Direct standard), lets devices connect in about one second compared to seven or eight. The goal is to integrate the Wi-Fi sensing with existing vehicle sensor-based detection and alerting systems.
