蘋果可能正在測試LiFi技術:速度比WiFi快一百倍
Apple could be testing a technology called Li-Fi, according to code found within iOS 9.1.
根據從iOS 9.1系統中發現的代碼來判斷，蘋果公司可能正在測試一種名爲LiFi的新技術。Li-Fi was invented by Harald Haas, a researcher at Edinburgh University, and has since been worked on by a number of companies.
LiFi技術是由愛丁堡大學的研究員Harald Haas發明的，現在已經被多家公司所採用。The technology is around 100 times faster than Wi-Fi — with speeds of around 224 gigabits per second — because it uses the light spectrum to transmit data.
這項技術的傳輸速度比WiFi快100倍，可以達到每秒224GB，這主要是因爲它使用了光譜來傳輸數據。
It's unclear how Apple intends to use the technology or whether it will make it into the rumoured iPhone 7.
目前還不清楚蘋果將如何使用這項技術或者是否會將該技術應用於iPhone 7中。
There is currently no technology on the market that uses Li-Fi, so there is little to compare it to. However, one use could be talking to other devices within the same room, such as the Apple TV. The high data speeds mean a film could be sent from an iPhone to the TV within seconds, ready to stream. (This is just speculation, though — it's still early days for the technology.)
現在市面上還沒有使用LiFi的技術，因此不存在可比性。其中一種應用方案是在同一房間內的設備間通訊比如iPhone與Apple TV之間的通訊。它的高速數據傳輸能力意味着將一部影片從iPhone傳輸到電視可能只要幾秒鐘就行了。（這只是人們的一種猜測，這項技術還處於早期研發階段。）Apple filed for a patent in 2013 that talked about an "optical modulation using an image sensor" that used the iPhone's camera to transmit data via light, a technology that could be used with Li-Fi.
蘋果在2013年提交了一份專利申請，涉及到“一種使用圖像感應器的光模塊”，它可以利用iPhone的攝像頭通過光來傳輸數據，這種技術可能用到了LiFi技術。
