Re: [Bluez-users] using class 1 dongle

["Thomas Kear" <thomas.kear@gmail.com>]

The "100 metre" range depends on both devices being class 1.  If you
have a class 1 device talking to a class 2 (10m) device, your maximum
range may be higher than 10 metres due to the increased transmit power
and recieve sensitivity, but won't be anything like 100m.

Unlike 802.11 there is no user-adjustable transmit power either,
you're stuck with the dongle figuring that out for you.

If your phone is class1 (a few are, but 99.5% are class2) then you
genuinely have an issue, which could be as simple as a wall in the way
which is blocking the signal, or as difficult as your neighbour having
a leaking microwave oven.
