The OnCell G3100 series offer connectivity to all tri HSDPA/UMTS frequency bands (850/1900/2100 MHz), as well as all quad GSM/GPRS/EDGE frequency bands (850/900/1800/1900 MHz) used in Europe and the United States, allowing seamless global roaming at locations around the world.
To achieve this Ethernet-to-cellular function, the OnCell G3100 series is assigned an IP address by your service provider (your "cellular ISP") and outgoing TCP/IP connections are handled with Network Address Translation (NAT). This allows any number of local Ethernet devices to act as outgoing TCP/IP clients to access remote servers. However, the OnCell G3100 series appears as a single IP address to the "public" Internet. The OnCell G3100 works in a manner similar to a router. Ethernet devices connected to the OnCell's LAN port will be hidden from the outside world thanks to the OnCell's NAT function.
The OnCell G3100 series offers versatile operation modes such as Reverse Real COM mode for cellular network structures (to handle the IP address issue) and automatically generates virtual COM ports to match serial ports to allow you to communicate with remote serial devices. The OnCell G3100 series products also come with a built-in relay output that can be configured to indicate the priority of events when notifying field engineers and the two digital inputs allow the connection of basic I/O devices. In addition, the OnCell comes with redundant power inputs to ensure non-stop operation.
