The Stevens Cell-Net is a smart cellular data modem designed for remote environmental monitoring & control M2M applications. Cell-Net is designed to be a smart cell modem that manages power consumption, data delivery information, communication protocols, and system health diagnostics. Cell-net is also designed to easily link legacy data loggers / RTUs to the internet in being an effective conduit that shortens the communication link between the sensors and data presentation / analysis on-line. This is accomplished by all communication protocols and data buffering control being programmed into the Cell-Net modem.

Communication via the internet to servers use HTTP, FTP protocols, or both for dual communication option. Selecting HTTP protocol enables direct connection to a cloud-based web server, such as “Stevens Connect” for data management, custom calculations and presentations.

The Cell-Net modem has advanced data buffering capabilities that enables various data transmission scheduling to occur at user defined set time intervals or data packet events. Such data buffering enables power management features and is used to ensuring reliable transmission and delivery during periods of high cellular data traffic via the cell network.

Cell-Net features user-selectable header information, which can include signal strength, battery voltage, time, date, latitude, and longitude information with every data transmission.
