iPhone 7 might be the first smartphone to support Li-Fi
January 19, 2016
Internet will reach your house through light bulbs in about 170 times faster (theoretically) than current Wi-Fi technology (considering the standard 802.11ac wave 1, with a maximum throughput of 1.3 Gbps). Now imagine, with this ultrasonic speed, you will be able to download a movie in 4k in seconds!
What is Li-Fi?
Li-Fi is the supersonic alternative to Wi-Fi. In 2011 this new technology reached actual speed of 3 Mbps, despite the theoretical projections point to speeds that can reach 224 Gbps (gigabits per second). Recently, responsible for the Li-Fi project announced that they have managed to reach 1 Gbps (approx. 8 Gbps) in real scenarios.
The Li-Fi technology uses light to transmit information through the air. We know that the optical fiber already uses light to carry data at high speed, using the reflection of light in fibers to achieve a very high speed and no loss of data along the way. However, transmitting information by light rays through the air is much harder, for this there is a “tunnel of light” to guide the signal to take it where it must go.
Li-Fi support on the iPhone 7
Since iOS 9.1 Apple tries to “hide” the work that has been done towards the support of the Li-Fi communications technology. However, there are some people who have devoted to the subject and discovered a library called “LiFiCapability”, which is already integrated in iOS.
Although, this technology is still at an experimental stage, Apple intends to be one of the first manufacturers to support it. It is also known that in 2013 the Cupertino company registered a patent which title was “optical modulation using an image sensor”.
Do you believe that the next iPhone will come with Li-Fi technology?
