The PlayStation 4's Remote Play feature works over a high-speed LTE cellular network, according to a video demonstration published today on YouTube.
YouTube user "The Phawx" took his T-Mobile cell phone and his PlayStation Vita to downtown Manhattan to see if he could tether the devices together, launch the Vita's PS4 Link app and connect the handheld to the console to play Resogun.
The Remote Play feature, which allows players to use Sony's handheld to control and play games on its next-gen console, is part of the company's DNA, PS4 lead architect Mark Cerny told Polygon earlier this week. Although Sony recommends that both devices be connected to the same Wi-Fi network, it doesn't rule out the possibility that Remote Play will work on a wide area network.
According to a speed test "The Phawx" ran with a two-bar wireless signal, he was averaging a download speed of 6.15 megabits per second at a 38 millisecond ping. After the PS Vita connected, it registered a connection speed of 5.7 Mbps and an upload speed of 1.8 Mbps.
Check out the video above to see what happens after he takes control of his PS4, which he says is about 10 miles away connected to a network with 100 Mbps download and 10 Mbps up. The result isn't optimal — he estimates about 150 ms delay — but it works, and it seems playable.
