The BiPAC 7800GZ, a triple-WAN 3G / ADSL2+ firewall router integrated with the 802.11g wireless access point and 4-port switch, is a cutting-edge networking product for SOHO and office users. Uniquely, the router allows users to directly insert a 3G / HSPA SIM card into its built-in SIM slot instead of requiring external USB modems. This design will avoid the common problem of compatibility issues of many different 3G USB modems. With the increasing popularity of the 3G standard, communication via the BiPAC 7800GZ is becoming more convenient and widely available - enabling users to use a 3G / UMTS HSDPA / HSUPA or GSM GPRS / EDGE Internet connection, making downstream rates of up to 7.2Mbps possible. Users can watch movies, download music on the road or access e-mail wherever a 3G connection is available. In addition, the integrated IPSec VPN function allows you to encrypt connections of up to 4 VPN tunnels to securely transmit data over the Internet, making the BiPAC 7800GZ a perfect unit for SOHO and office users.
