You can now put a new kind of ultra-fast wireless networking technology on your list of potential hardware advances that might be in tow for Apple's 'iPhone 7' refresh later this year.
As first spotted by Twitter user Chase Fromm, code strings in iOS indicate that Apple could be experimenting with an ultra-fast, light-based wireless data technology, dubbed Li-Fi.
In modulating visible light in a manner that is imperceptible to the human eye, Li-Fi promises a theoretical throughput capacity of up to 224 gigabits per second versus up to just a few gigabits per second for the current-generation 802.11ac Wi-Fi standard.
