Home Surveillance & More via Radio Frequency Signatures #CES2017
A pair of devices that uses existing WiFi to detect movement in a house with no need for cameras is what Cognitive Systems promises with its Aura sensors. These sensors detect disturbances in the radio frequency signals emitted by home WiFi routers to determine motion, which makes it ideal for home surveillance, as well as…

More Efficient TV White Spaces #CES2016
Eight times higher transmit power is what the new IEEE 1900.7-2015 TV White Space standard promises. According to LETI, a French research organization and contributor to the standard, this translates into 75% longer distance for a given data rate. It achieves this performance gain without interfering with adjacent TV channels. The extended range afforded by this new modulation…
