As an aside… I am been amazed lately at the Bluetooth range I do get. I remember when the technology was in its infancy and it was extremely short range… like same room no walls if you are lucky. These days I can leave my laptop at the docking station and walk nearly across the building before having issues.
- lxgr 3y agoIs this with Airpods by any chance? There are three Bluetooth transmission power classes, and traditionally, most devices (including headphones and headsets) used to be Class 2, which has a range of roughly 10 meters, but Airpods are Class 1, which has 10 times that. There's no real signal processing magic happening other than (significantly, due to the inverse square law involved) bumping up the maximum transmit power from 2.5 to 100 mW. Both ends of a connection need to support Class 1 for that to work, but at least Apple's devices have consistently done so for many years now as far as I know.
- crims0n 3y agoAh, yeah they are AirPods… makes sense and good to know - thank you!
- eternityforest 3y agoWhat's the point of having different classes? Was it harder to make the higher power chips when Bt was invented? Now almost everything can do at least 25mW or so, and with dynamic TX power it's not like having too many mW is a problem, it will just turn it down if not needed.
