Apple could be testing a technology called Li-Fi, according to code found within iOS 9.1.
根据从iOS 9.1系统中发现的代码来判断，苹果公司可能正在测试一种名为LiFi的新技术。
Li-Fi was invented by Harald Haas, a researcher at Edinburgh University, and has since been worked on by a number of companies.
LiFi技术是由爱丁堡大学的研究员Harald Haas发明的，现在已经被多家公司所采用。
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.
这项技术的传输速度比WiFi快100倍，可以达到每秒224GB，这主要是因为它使用了光谱来传输数据。
It's unclear how Apple intends to use the technology or whether it will make it into the rumoured iPhone 7.
目前还不清楚苹果将如何使用这项技术或者是否会将该技术应用于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.)
现在市面上还没有使用LiFi的技术，因此不存在可比性。其中一种应用方案是在同一房间内的设备间通讯比如iPhone与Apple TV之间的通讯。它的高速数据传输能力意味着将一部影片从iPhone传输到电视可能只要几秒钟就行了。（这只是人们的一种猜测，这项技术还处于早期研发阶段。）
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.
苹果在2013年提交了一份专利申请，涉及到“一种使用图像感应器的光模块”，它可以利用iPhone的摄像头通过光来传输数据，这种技术可能用到了LiFi技术。
