Happy World WiFi Day! Today, there are still 4 billion people around the world with no Internet access, that's why this global initiative sets out to bridge the digital divide by urging the industry’s biggest names to connect the unconnected. In searching for connectivity, NNN developed the WiFi Angels app, a smartphone application to experience electromagnetic radiations by turning the WiFi networks around you into a choir of singing angels. Download it for free on your Android smartphone. Next time when you search for WiFi, just follow the angels.
