Think of it like the congested highway you use to drive to work suddenly getting new lanes, or getting an entirely new highway to commute on—things hopefully start moving quicker. “It will give people faster Wi-Fi, basically,” says Anthony Rowe, an associate professor of electrical and computer engineering at Carnegie Mellon University and a member of the institute’s CyLab.
Rght now, many routers work on two different frequencies—either 2.4 GHz or 5 Ghz. The 2.4 band (it’s one small swath of frequencies in that neighborhood) has a reputation for traveling further, but offering slower speeds, mostly due to congestion and interference. The 5 Ghz band is known for not going quite as a far distance-wise, but providing faster speeds, so those episodes of The Good Place don’t need to buffer; there’s more bandwidth in what’s actually three different frequency segments in that frequency region.
