The introduction says "Bluetooth is a wireless technology standard" but that is not much of a definition. A standard can be many things, such as a standard color coding for identifying something. Is Bluetooth a protocol? List of Bluetooth protocols says it is "wireless data exchange standard" and that it "uses a variety of protocols". Sam Tomato (talk) 02:41, 5 March 2015 (UTC)
I am curious as to why bluetooth devices disconnect and must be re-connected all the time if they are idle even for a few moments. This seems to be a pervasive problem, seemingly currently addressed (if at all) at the device driver level. Is this a bluetooth protocol issue? Is it something else? In any case that behaviour is totally insane, since the driver has no way of knowing what the user is doing. It is very difficult to find this information anywhere.

The article says "2.402–2.480 GHz [...] the Bluetooth protocol divides the band into 79 channels (each 1 MHz wide)". From 2.402 to 2.480 GHz it is only 78 MHz. I do not think that 79 channels, each 1 MHz wide, fit in that interval. I do not know if it should be 78 channels or if it is 2.4015–2.485 GHz (by the way, the reference is broken), but it seems that a change is necessary somehow. DrTobbe (talk) 17:45, 8 April 2015 (UTC)
The 79 channels (for "classic BT", i.e. BR/EDR) are each 1 MHz wide and centered at 2402..2480 Mhz. There's a guard band of a couple of MHz above and below the channels actually used William M. Connolley (talk) 19:47, 8 April 2015 (UTC)
