Samsung’s Galaxy S10 will be one of the first smartphones to support the faster Wi-Fi speeds offered by Wi-Fi 6. Regulatory filings from Samsung, spotted by Droid Life, reveal that three models of the upcoming phone will include support for the brand-new Wi-Fi standard.

Those speed gains won’t do much right away, though. Almost no one has a Wi-Fi 6 router, and you’ll need one to take advantage of Wi-Fi 6’s improvements. Wi-Fi 6 also doesn’t offer immense speed gains for individual devices. It’s supposed to improve performance in homes or on Wi-Fi networks where a ton of devices are connected (say, a home with a bunch of smart gadgets installed), and those devices will need Wi-Fi 6 to really see benefits, too.
