This is the portable WiFi signal booster that extends the range and improves the signal strength of a wireless network. The device simply plugs into an AC outlet, connects to a wireless network, and rebroadcasts the signal to provide a faster, more reliable WiFi connection at a hotel or airport. The wireless hotspot's power prongs fold into the device and the entire unit fits in a pocket for simple, unobtrusive storage when traveling. It uses the most advanced 802.11 n protocol (compatible with b and g devices too), enables up to 150 Mbps download speed, and allows up to 10 devices to access the Internet at once. It provides WEP, WPA-PSK, and WPA2-PSK security for optimal privacy. The unit also converts a wired Internet connection into a wireless network via a built-in Ethernet port. 3 1/4" L x 2 3/4" W x 1" D. (3 1/4 oz.)
