Tenda 3G/4G 300Mbps Wireless N Router is designed for wireless network deployment in remote locations or temporary command centers. The device provides 3G/4G wireless WAN and wired Ethernet connectivity. By simply plugging into a compatible 3G/4G USB modem, a secure, wireless (up to 300Mbps) network is created, which can be shared by multiple users. The device automatically fails over to your wired connection if 3G/4G signal is lost. In addition, the universal repeater functionality enables the 4G630 to connect to existing WiFi for a secure connection.
