New Internet kid on the block, Li-Fi becoming the new trend?

The days where we all struggled using Dial-up internet connectivity, moving up to copper cabling; finally advancing to Fibre optic cable giving us wireless connectivity. Well fear no more Li-Fi will change everything!

With this new kid on the block we might end up seeing some extraordinary connectivity. It was highlighted on many websites of the introduction of Li-Fi (Light Fidelity). Now what is the different between the traditional Wi-Fi, which we have all been used to? Well this new technology in the blueprints are expected to reach levels we thought weren’t even possible.

Wi-Fi (Wireless Fidelity) works on the basis of a LAN (Local Area Network) and can operate multiple devices. Dependant on the type of package you have with your provider would depends on the levels of Bandwidth you have available. Also the main functionality of Wi-Fi is that it work using Radio waves. Well Li-Fi works in the same way as Wi-Fi but it can send data at a much faster rate, so fast the human eye can’t register it. We were used to having internet connectivity of up to 200MB/s transfer rates. Well Li-Fi uses, you guessed it; light waves to transmit the data. In lemans terms, the speed of light is now being put into force to send information.

The scale of the spectrum of Wi-Fi is near enough maximum capacity, and this could be the cause of network bandwidth issues and bottle-necking of the internet. Well Li-Fi doesn’t have any limitations on the transmission and bottlenecking. This is because the spectrum of light is 10,000 times larger than the radio wave spectrum.

The rates in which it can send information is amazing. It hasn’t been officially tested, but it’s said that it can transfer up to 224GB/s. YES GIGABITE PER SECOND! That’s you downloading near enough any file in ridiculous speeds!

Some routers at the moment can transmit across cable connections 10GB/s and that’s using Fibre Optic cabling which uses light across the cable. Well computer engineers are looking at using the light created in fibre optic and using it on a wireless infrastructure. Obviously it’s still not realised when it will be available in the public domain, but you can be sure that it will could cost a lot of money to implement it.

The first leak of devices which are coded into supporting the new Li-Fi technology was a script of an Apple device. Now does that beg the question that the new iPhone7 will have Li-Fi capabilities or is the technology not quite ready to be released. There will obviously be issues when it is realised with an overload of users all accessing it and a lot of bottlenecking. With the possibility of mass users will there be specific hotspots which will have it? Will they charge you to access it?

Security of your information from potential hacking has been discussed to understand the way light speed of transmission is carried out. It’s carried out over short distances so before the information can be traced and adapted by hackers the data is gone. The only major issues which could cause a problem is that it transmits over short distances, has low reliability, and the cost to install the technology is a shortfall. It has been highlighted it will be a lot cheaper to use than Wi-Fi, but with the issues of only short distance transmissions and reliability issues.

Is it really a technology that needs more testing before it’s released in the public domain?
