Bluetooth 6.2 – more responsive, improves security, USB comms, and testing

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

Why do you assume innovation and new frequencies are all that related. There are some things new frequencies can help with. Higher bandwidth, lower congestion, but there's also problems with penetration and range. Meanwhile, the protocol itself is packed with modes and features.

It's a joke?

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.

Excuse me?

I'm continually astounded at how well it works. I've forgotten my phone in the basement and walked all the way up to the third floor of a building without having the audio I was listening to on my BT earbuds drop out.

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.

Higher bands are coming. Probably a long time before you will see it in a consumer device though.

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