I'm just going to put this information here: the use case for 46Gb WiFi is going to be extremely niche. There is nearly no legitimate use case where you can achieve that speed on your phone.
The problem here is that:
What does this mean?
Your connection speed on a wifi 7 device WILL be bottlenecked by your single-core CPU speed, even if you are doing absolutely nothing except transmitting data. This assumes you are only using a TCP single connection (e.g. downloading a file from a website). But that's the majority of use cases unless you are running a server (in this case on your phone).
I haven't checked what CPU the Pixel 8 uses. But my Pixel 7 has a Cortex A-78. I also don't have the raw data handy for the 3Ghz A-78, but I do have data from the 2Ghz A-53 connected to a 100Gbps Ethernet NIC which is around 8-9Gbps. The A78 generally outperforms the A53 by 1.5x (At least that's the characteristics on the Nvidia Bluefield DPUs). So we can assume 12-14Gbps max for a single connection with Wifi 7 running on a state-of-the-art ARM CPU.
That is still nowhere near 46Gbps. It's like mounting a Vulcan Minigun on a bicycle.
To use the full wifi bandwidth, you would need to have multiple connections running on different cores. That's also not including the switches/servers connected to the wifi AP. Unless you are running a Redis server on your phone, I see no reason why Wifi 7 would be needed unless the remaining hardware is upgraded significantly.
To use the full WiFi bandwidth you'd probably also need to connect your phones antennae to the access points antennae via coax.
Nobody's ever going to get 46Gb/s with 7 just like nobody actually gets 1gigabit with AC. Real speeds tend to be vastly lower than rated, and splitting the airwaves with other stations is reason enough to minimize transmit time in any case. A busy area is going to benefit from phones having Wi-Fi 7 even if those phones can't process a 46gbps tcp stream.
It really annoys me when people look at max rates of networking technologies as though they're minimums for that technology to be useful. You don't have to use all 10gigabits of 10gbps for the upgrade from gigabit to be worthwhile, same with all others.
