The problem with 5G and any other regulated frequency spectrum is the spectrum crunch. There have been talks of a looming spectrum crunch since the early 2000s. The radio spectrum is a finite resource. As such, it can only allow so few broadcasts before it runs out of available frequencies. And as the demand gets heavier, the day it arrives also comes sooner. What is the solution? LiFi. It is a wireless optical networking technology. Specifically, it is a form of visible light communications (VLC) system that makes use of** light-emitting diodes (LED) for data transmission.** LiFi has a special distinction from other VLC systems. Similar to WiFi, LiFi is the only form of VLC that allows the bidirectional transmission of light. However, instead of the radio spectrum, it makes use of the visible light spectrum through LED light bulbs outfitted with a special chip. LiFi is considered more superior to WiFi. Data transmission tests have reached speeds of up to 224 Gbps, roughly 100 times faster than WiFi. Right now, 5G requires the addition of repeater towers because its much higher frequency results in its propagation being the inverse of distance traveled. In other words, it takes much more energy to transmit 5G. This is why repeater towers are springing up on nearly every city block. Hell, that's already a line-of-sight situation. LiFi can do the same thing and faster. Hell, you don't even need to transmit through the air if you are connected to the electrical grid. The visible light spectrum is also broader as opposed to RF – about 10,000 larger than the entire radio frequency spectrum. This is the visible light spectrum. What about the non-visible light spectrum? With LiFi, every source of light can connect you to the internet. In the near future when the technology is already available to the general public, street lights, building lights, and transportation lighting can all communicate wirelessly and you can access the internet wherever you may be.
