I don’t know if it’s the improvements in the Airport Extreme card or if the antennas are just better on the 12″ PowerBook G4, but the range on this puppy is just waaaay better than before on my old Titanium PowerBook G4. I can get full-strength reception anywhere in the house now, including places I could not even work before like the far side of the living room couch or on the front porch. I can sit on the lawn on the opposite side of the house from where the signal origin. I can see three other networks from my neighbors, all equally as strong. This is all using one of the original AirPort old-school base stations with 802.11b. Nice!
