Cellgo

Low Current 2G/3G Modem
Mobile Connectivity for Power-Constrained Devices

Cellgo is a compact cellular modem allowing devices with serial port to connect to the 2G/3G cellular network. Cellgo integrates a SuperCapacitor enabling power-constrained products, such as battery-powered medical devices, to cope with power peaks required during cellular transmission. Cellgo can be powered directly through the RJ45 serial connector for a convenient single cable installation or with an optional charger.

This cost-effective 2G/3G wireless modem comes with a powerful TCP/IP stack, all in a compact and stylish form that makes it ideal for Telehealth and in-home applications. Cellgo is optimized to provide a reliable and price competitive solution to eHealth projects, offering a short time-to-market option for connecting medical devices wirelessly.

Based on the award winning eDevice TCP/IP stack, Cellgo includes, in addition to standard TCP/UDP sockets, a DNS client, an FTP client and an email client. 

Cellgo, by virtue of its low-cost achieved through hardware and software optimization, is the easiest way to enable electronic equipment to communicate wirelessly. The existing serial port is simply connected to the RJ45 connector on the Cellgo, allowing Internet connectivity through cellular networks using standard AT and AT# commands.

As an external network accessory this cellular modem allows approved medical devices to migrate to cellular connectivity with a very low regulatory impact.
