How much more innovation can this tiny slice of 2.4GHZ spectrum support?

It’s wild to me just how much Bluetooth can do. When it was new my mental model had it binned as a “basic comms within 10 feet”.

Last week my kid got to the bus stop before “Controller Disconnected” revealed the PS5 controller was in his backpack.

I wonder if "controller disconnected" is a combination of distance and time.

Meaning he got 25 feet away when communication stopped, then there was a delay while retries/timeout happened, and then the message when 100 feet away.

Good thought. I’ll test this with a faraday cage maybe? Would a microwave work? Does it have to be on?

you could just walk slow vs walk fast?

That sounds less electrifying.
