Apple is apparently testing out Li-Fi (Light Fidelity) for its future iPhones. The news of this new feature was discovered in some recent iOS code by Apple Insider.
According to the report, Apple has included a feature called LiFiCapability since iOS 9.1, which could suggest that they currently have some iPhones in testing using Li-Fi technology.
Understanding Li-Fi Technology
Li-Fi works in a similar way to an infrared remote; it transmits data by rapidly modulating a light source. The light is then received by a sensor and translated into an electronic signal. Unlike traditional Wi-Fi, which uses radio waves to transmit data, Li-Fi uses visible light, which can be emitted from LED bulbs. This means that the lights in your house could act as an access point for the feature, making it an innovative and potentially ubiquitous technology.
One of the most significant advantages of Li-Fi is its speed. It is considerably faster than Wi-Fi, with speeds of up to 224 gigabits per second. To put this into perspective, this speed could allow you to download 18 movies of 1.5 GB each in just one second. This incredible speed is due to the high-frequency spectrum of visible light, which is much larger than the radio frequency spectrum used by Wi-Fi.
Potential Applications and Challenges
The potential applications of Li-Fi are vast. For instance, in environments where radio frequency communication is not ideal, such as hospitals or airplanes, Li-Fi could provide a safer and more efficient alternative. Additionally, in urban areas where Wi-Fi networks are congested, Li-Fi could offer a faster and more reliable connection.
However, there are also challenges to the widespread adoption of Li-Fi. One of the main limitations is that light cannot penetrate walls, which means that Li-Fi would require multiple light sources to cover different rooms in a house or building. Moreover, the technology is still in its experimental stage, and it could be a few years before we see it implemented in consumer devices.
Apple’s interest in Li-Fi is a promising sign for the future of this technology. If Apple successfully integrates Li-Fi into its devices, it could pave the way for other tech companies to follow suit, leading to a broader adoption of this high-speed wireless communication technology.
In conclusion, while Li-Fi is still in its early stages, its potential to revolutionize wireless communication is immense. Apple’s testing of Li-Fi in its future iPhones is an exciting development that could lead to faster and more efficient wireless communication in the near future.
