If you want more internet speed then the answer to your woes could be LiFi.
Harald Haas, Chair of Mobile Communications, at the University of Edinburgh is also the co-founder of pureLiFi Ltd. For several years, Haas has been studying ways to communicate electronic data signals and design better ways to transmit them wirelessly.
In a video in 2011, Haas demonstrated a technique to do away with the dependence on spectrum and also conserve energy by using light.
The technique demoed by Harald Haas during a TED Talk has now been specialised to deliver data transfer speeds of up to 1Gbps, which is approximately 100 times faster than the currently available Wi-Fi technologies.
Similarly optical technologies have been employed with Gpon or Gigabit Passive Optical Network which aimed to deliver a gigabit worth of bandwidth of data over an optical fibre network. It is in line with these initiatives that projects such as Google Fiber took off and became a reality.
