I have previously written about this technology and haven’t got much of it lately until now. This time it’s being marketed as a compliment to 4G/5G and WiFi, not a replacement. What comes to mind is the “complementary” nature of Bluetooth and WiFi. To explain from Wikipedia:
Bluetooth is a wireless technology standard for exchanging data over short distances (using short-wavelength UHF radio wavesin the ISM band from 2.4 to 2.485 GHz) from fixed and mobile devices, and building personal area networks (PANs) (“Bluetooth,” 2017)
As Bluetooth come to mind, the IEEE working group associated with this also sees LiFi as a Personal Area Network (“IEEE 802.15.13 Task Group,” 2017). For this technology to take off, the current usage of Compact Fluorescent Lamps would have to give way to LED light bulbs. The transition from Incandescent light bulbs isn’t fully complete so this could be a while, compounded by the current Administration and their views on such energy advances.
