The difference between Class 1 and Class 2 devices is the range/power at
which they operate.

Class 1 is rated at 100m
Class 2 is rated at 10m
I think there is a class 3 as well with a range of about 3 feet!

Phones are mostly class 2 or 3, access points are class 1, other stuff
depends on size, power requirements etc.
