GSM/GPRS network connectivity, which is ideal for M2M data exchange, requires the supply of enough energy to cope with high consumption peaks of external cellular modems. Many devices are not able to supply such power so the modem has to be plugged into a dedicated power supply. This constraint increases the upfront investment and makes the on-site installation process more complex as it requires an additional cable and power plug.

eDevice, a French company, has introduced an external model known at Cellgo that allows serial devices to connect to the network through a single cable which carries both the data and power signals. It enables power-constrained products, such as battery-powered devices, to handle power bursts required during cellular data transmission. Cellgo's maximal consumption is below 400mA.

The product is driven through easy-to-use AT# commands that trigger TCP socket data transfers, email sending, and FTP file reception for immediate transfer of data via the Internet through the cellular network. Cellgo is equipped with an internal quad-band antenna and internal SIM cardholder.

Cellgo can be used with different types of “already-in-the-field” devices equipped with serial ports including remote patient monitors, telecardiology monitors, alarm and security systems, TV set-top-boxes, point-of-sales equipment, energy metering systems, etc.

eDevice is a leading provider of complete M2M solutions. There are over 3 million products in the field that are embedded with eDevice’s technology. eDevice is ISO-9001 certified and serves international customers including Fortune 200 companies in various activity areas such as metering, security, monitoring, with a specific focus on mHealth and telemedicine.
