Current Wi-Fi tech works really well, but it wasn’t designed to cope with the huge 4K video files that you can record on the latest iPhones and iPads.
We’ve previously mentioned the next generation of Wi-Fi that’s due later this year, called 802.11ad or WiGig, and which is designed to speed up the transfer of HD video files. Of course, that will mean buying a new WiGig router, along with a new iPhone and Mac that support it, too.
A more affordable option is a technology called TransferJet, from Toshiba. This uses small adaptors that can plug into a Lightning or USB port on various devices, and which can transfer 1GB of video over a wireless connection in about 20 seconds.
Adaptors cost only about £25 each. Right now, the TransferJet app is only available for iOS, Android and Windows PCs, while the Mac version is dawdling behind. However, the tech’s convenience could make it handy for backing up 4K videos when you’re on holiday or working outdoors.
