Mac: Measuring Wireless Signal Strengths

Very interesting article i found here, about Optimising wireless reception from a distance, using the following command in Terminal:

while x=1; do /System/Library/PrivateFrameworks/Apple80211.framework/Versions/Current/Resources/airport -I | grep CtlRSSI; sleep 0.5; done

it returns a value in dBm, the wireless radio signal strength.
