After launching its mobile 5G network in late 2018, AT&T today announced that it's reached another 5G milestone.

AT&T has surpassed speeds of 1Gbps on its mobile 5G network, touting that it's the first U.S. carrier to reach that goal. AT&T achieved these 1Gbps speeds in multiple cities using the Netgear Nighthawk 5G Mobile Hotspot that it launched along with its mobile 5G network last year.

To give you an idea of how fast 1Gbps is, AT&T says that you could download a two-hour HD move in 20 seconds.

There are lots of upgrades that 5G can offer over 4G, but one of the biggies is faster speeds. We're already excited for 5G, and hearing that AT&T achieved 1Gbps speeds on its mobile 5G network using a commercial device is great to hear. It is important to note that 5G is still very young and it'll likely be a while before you're getting 1Gbps speeds on a 5G smartphone, but still, this is an exciting taste of things to come in the future.
