An anonymous reader writes: Recently discovered code in iOS suggests that Apple may be exploring the feasibility of incorporating Li-Fi functionality into future iPhone models. Li-Fi, in case you’re unfamiliar, is a technology capable of transmitting data via light. What makes Li-Fi so compelling is that it’s effectively Wi-Fi on steroids and can transmit data more than 100 times faster than a standard Wi-Fi connection.
In lab conditions, researchers this past February were able to achieve Li-Fi speeds of 224 gigabits per second, fast enough to download multiple HD movies in less than two seconds. While Li-Fi still remains something of an experimental technology, iOS 9’s references to the blazing fast data transfer technology are certainly intriguing.
Is this likely to be a feature with the iPhone 7? Not a chance. As it stands today, Li-Fi, despite its promises of speed, is still plagued with a number of limitations. At a base level, it can’t work through walls because, well, visible light can’t travel through walls. In this respect, Wi-Fi has a huge practical advantage. Not only that, but a Li-Fi enabled device needs to have a direct line of sight to an operational light sensor to operate. This operational limitation, however, does make Li-Fi a more secure transfer protocol than Wi-Fi. Today, Li-Fi is far from being a true Wi-Fi replacement, but it’s not out of the realm of comprehension that Li-Fi, in the future, may dutifully serve as a Wi-Fi supplement.
