Could your smartphone prevent a car from hitting you? General Motors and other researchers think that’s a possibility【C1】______an emerging wireless standard works its way into the latest smartphones and new cars.
First seen in 2010, Wi-Fi Direct【C2】______ultrafast device-to-device connections over the same radio waves that smartphones, computers and other electronics currently use to connect to routers and home networks. The【C3】______here is that unlike your application-enabled television, Wi-Fi Direct doesn’t【C4】______the Internet. Rather, it’s【C5】______connect local devices directly to each other【C6】______as little as a second, and unlike Bluetooth, the connection doesn’t require special pass keys and works at more than double the【C7】______, at about 656 feet apart. GM says future cars could【C8】______pedestrians carrying Wi-Fi Direct smartphones, gather their【C9】______locations and warn the driver through existing active safety systems such as forward collision【C10】______and auto-braking.
Wi-Fi Direct is one part of GM’s research on vehicle-to-vehicle and vehicle-to-infrastructure【C11】______in which both cars and roadways become【C12】______aware and adaptive to real-time information. More and more automakers, such as BMW and Hyundai, use a subscription-based 3G cell network to connect a car’s information & entertainment system to the Web for things such as【C13】______searches. A few automakers, such as Ford and Audi,【C14】______wireless hotspots that allow full【C15】______to the Internet from any mobile device. By 2015, Ford said it【C16】______80 percent of the vehicles it sells in North America to have a Wi-Fi connection.
Wi-Fi Direct currently allows file【C17】______between two electronic devices【C18】______having to pair them. If the technology becomes popular and【C19】______it could pull the market away from Bluetooth, the short-range wireless standard for in-car telephone calls and portable audio. With Bluetooth, there isn’t one【C20】______way to connect a device—and many times, as we’ve often found, it still doesn’t work. According to data from the National Highway Traffic Safety Administration, nearly 4,900 pedestrians and cyclists were killed by cars last year, for which data were available.
