The effective range of Wi-Fi, and other wireless communications used in Internet of Things networks could be increased significantly by adding wireless noise, say scientists.
This counter-intuitive solution could extend the range of an off-the-shelf Wi-Fi radio by 73 yards, a group led by Brigham Young University says. Wireless noise, a disturbance in the signal, is usually unwanted.
The remarkably simple concept sends wireless noise-energy over-the-top of Wi-Fi data traffic in an additional, unrelated channel.
