Lighting That Produces Wi-Fi


A new fluorescent lamp emits Wi-Fi signals

What if you could leave those clunky routers behind and distribute Wi-Fi connectivity throughout the building using your existing lighting system? A team of researchers at the Universiti Teknologi MARA in Malaysia has developed an antenna that can do it affordably.

Created by enclosing ionized argon and mercury gas in a common fluorescent tube, the device becomes functional when the lighting element is turned on, changing the gasses to a plasma. A coupling sleeve is used to store the electrical charge, making the resulting plasma column highly conductive and useful as a smart antenna for 3G/3.75G/4G Wi-Fi to be transmitted and received.
