The effective range of Bluetooth devices is dictated by their power output.
Class I devices are reckoned to have a maximum line-of-sight range of 100
metres. To accomplish this, they can use up to 100mW of power. Class II
devices are consume a maximum of 2.5mW and have an effective range of 10
metres, Lastly, Class III devices are the baby of the bunch, using up to
1mW, with an effective range of 1 metre.
I've seen some Bluetooth dongles with antennas claiming the 100m range.
