Overview
This key chain sized Wi-Fi detector instantly detects hot Wi-Fi spots with the push of a button. The number of lights indicate the signal's strength, and the green LEDs light up fixedly to indicate that a signal is available while a red LED flashes to indicate no signal. It can detect 802.11b and 802.11b/g signals up to 200 feet away. No need to boot up your notebook, and no computer or software needed.
