Actually there are three classes of bluetooth: Class 3 with with 0 dBm (1 mW), 100M or so range (usually as a seperate dongle, not many devices have this capability built in as it eats batteries, however several "base station" products do it). Class 2 with 4 dBm (2.5 mW), 10M or so range (the "usuall" one) Class 1 with 20 dBm (100 mW) 10cm range (i.e. physically next to something).
[...]Ummm, why does the range go down as the power goes up? Should there be "-" signs in front of those dBm values? Or are they listed in the wrong order? 100 mW should get you a lot farther than 10 cm if you have any antenna at all.
