In an update on Samsung's website a couple of days ago the company claims to have surpassed the current threshold for transferring data via wi-fi. They say a 1GB movie would take less than 3 seconds to transfer between devices with their new technology.
Current wi-fi speeds max out at 866Mbps (108MB per second) using 2.4GHz and 5GHz wi-fi tech, but Samsung say that their 60GHz tech 'maintains maximum speed by eliminating co-channel interference, regardless of the number of devices using the same network.'
Samsung developed an improved antenna which allows the signal and data to travel further with less chance of it being lost in transit.
Such technology means HD videos can be streamed from mobile devices to TVs completely in real-time, without any delay. For PC gamers this could also mean streaming games using Steam's in-home streaming feature would be totally lag-free.
