In the same round of Switch 2 filings at the Federal Communication Commission (FCC) in the US, it seems Wi-Fi 6 support has been confirmed.
As highlighted by The Verge, Wi-Fi 6 translates to ”faster Wi-Fi in your Switch 2” – with the outlet expanding on what to potentially expect on this front (and what Nintendo’s new hardware won’t seemingly support):
”The filings show it will support Wi-Fi 6 (802.11ax) networks with up to 80MHz of bandwidth, up from Wi-Fi 5 (802.11ac) on the original Switch. However, it doesn’t seem to have Wi-Fi 7 or Wi-Fi 6E, and it’s only crossed the FCC with tests for 2.4GHz and 5GHz networks, not the faster / shorter-range 6GHz band.”
The same source provides a basic description of this upgrade from Wi-Fi 5 (aka the current tech for the Nintendo Switch):
”Wi-Fi 6 is the next generation of Wi-Fi. It’ll still do the same basic thing — connect you to the internet — just with a bunch of additional technologies to make that happen more efficiently, speeding up connections in the process.”
