Now you no longer need to boot up your notebook PC just to find out whether you are near a Hot Spot! Our little Wi-FiFinder is an RF wireless device that detects Wi-Fi 802.11b and 802.11b/g signals. It captures Wi-Fi signals while avoiding interference from other devices such as 2.4GHz cordless telephones, A/V senders, microwave ovens and Bluetooth devices. Just turn it on and find where to get online without the hassles!
