Wi-Fi technology has helped bring a world of information to our fingertips via mobile devices, but a new certification program from the Wi-Fi Alliance aims to make the technology a bit more local. The Wi-Fi Aware protocol is designed to extend Wi-Fi's capabilities to improve on current proximity-based functions without the need for cellular, Wi-Fi hotspot or GPS connections.

This new protocol could make applications like multiplayer gaming, close geo-social networking and file sharing fast and secure within a typical Wi-Fi range of 100-150 ft (30-45 m). Airport gates could make your boarding pass automatically appear, or your favourite shop could advertise its specials to you as you walk by.

The Wi-Fi Alliance says continuous discovery of compatible devices is made possible without without putting undue strain on battery life, with multiple Wi-Fi Aware devices forming clusters that share a common "heartbeat" signal that contains information about the availability of nearby services.
