Researchers from North Carolina State University have developed a technique for measuring speed and distance in indoor environments, which could be used to improve navigation technologies for robots, drones—or pedestrians trying to find their way around an airport. The technique uses a novel combination of Wi-Fi signals and accelerometer technology to track devices in near-real time.

Look for low-power, long-range gear to be certified in 2018
A new low-power, long-range version of WiFi that bolsters Internet of Things (IoT) connections will be dubbed WiFi HaLow, the WiFi Alliance revealed today in advance of CES.
WiFi HaLow (pronounced HAY-Low) is based on the pending IEEE 802.11ah specification. It will be used in coming years for everything from smart homes and wearables to smart cities and connected cars where thousands of battery-operated sensors can be connected to a single WiFi Access Point (AP).
