Comment on The Paradox of Blackmarket Wired Bluetooth Apple headphones.
BarryZuckerkorn@beehaw.org 6 months agoto my knowledge, Bluetooth doesn’t work with airplane mode
The radio regulations were amended about 10 years ago to allow both Bluetooth and Wifi frequencies to be used on airplanes in flight. And so cell phone manufacturers have shifted what airplane mode actually means, even to the point of some phones not even turning off Wi-Fi when airplane mode is turned on. And regardless of defaults, both wireless protocols can be activated and deactivated independently of airplane mode on most phones now.
an airplane full of 100 people all on Bluetooth might create some noise issues that would hurt the performance
I don’t think so. Bluetooth is such a low bandwidth use that it can handle many simultaneous users. It’s supposed to be a low power transmission method, in which it bursts a signal only a tiny percentage of the time, so the odds of a collision for any given signal are low, plus the protocol is designed to be robust where it handles a decent amount of interference before encountering degraded performance.

I didn’t know that part (the rest yes). So much for using airplane mode to conserve battery. I suppose it’s the tower handshake that is most energy hungry in my experience.
100% although my comment was in the context of people who don’t really understand Bluetooth at all.
+1 for the rest, thanks.

Your understanding is slightly off.
Airplane mode Does In Fact Turn off your CELLULAR Radio This radio is what powers your (2/3/4/5)G and LTE (This is 4G btw) connection to the cell towers.
Most international radio communications laws can prohibit the use of Cellular Radio in flight; however they often don’t prohibit the use of shorter range radio technologies such as WIFI or Bluetooth.
It’s all about ‘loudness’. Think about it. Your phone must ‘scream louder’ at a farther away cell tower than it would need to communicate with a nearby WiFi router or a Bluetooth headset.

Also, phones don’t use a lot of power to purely listen for Wifi beacons. They’re not transmitting until they actually try to join, so leaving wifi on doesn’t cost significant power unless you just happen to be near a remembered network.

Your comment missed the mark entirely. Please don’t reply-guy me; I know what I’m talking about.
