When the 5G wireless standard hits the mainstream, our home internet speeds have the potential to be so fast that we’ll be downloading 4K movies, games, software, and any other large form of content at a fraction of the time we’re used to.

5G is the upcoming evolution of wireless 4G LTE, which is mostly used today for wireless mobile networks. It’ll offer incredibly fast wireless communication that can be used for a number of applications outside of mobile networks, one of which is home internet.

At Mobile World Congress this year, Samsung showcased its 5G Home Routers, which achieved speeds of up to 4 gigabits-per-second (Gbps), according to PCMag. That’s 500 megabytes-per-second, which could let you download a 50GB game in under two minutes, or a 100GB 4K movie in under four minutes.

To give you an idea of how fast that is, the average internet speed in the US as of 2016 is 55 megabits-per-second, which translates to a woeful 6.5 megabytes-per-second.

As PCMag’s Sascha Segan points out, however, Samsung’s router was right next to the transmitting 5G cell at the time of the demonstration. That means those speeds are probably only possible in a perfect scenario, where the 5G router is extremely close to the 5G radio cell without any interference, obstacles, or network congestion.

Still, even with 50% of that performance, we could be experiencing 2Gbps speeds at home. And even 1Gbps — 25% of the perfect scenario — would be great compared the US internet speed average.
