To identify the ideal Industrial Cellular Modem for your application we have developed the Modem Selector Tool which is a configurable filter to narrow down the results to match your exact requirements.

Siretta Modem Range

The Siretta range of industrial low power modem solutions are a family of cellular enabled modems which have been designed to an industrial specification to allow an easy connection for remote devices over the internet. The family of products supports a standard set of features including low power operation with a wide range and robust power supply, RS232 and USB serial connectivity and extended temperature spec as standard.

Each member of the modem family supports an embedded TCP/IP stack for simple network connectivity and an enhanced set of AT commands to support many advanced features such as FTP, email, SMS, CSD, direct data socket connections and over the air software updates. As a result the units are designed to be used as a direct replacement for existing equipment and can be easily setup with the correct commands to operate out-of-the-box.

In addition to the data communication services offered by the industrial low power modem family, they can also be configured to detect the cellular network provider, signal strength and perform a complete network survey to establish the optimum network for the location.

Siretta Industrial Low Power Modem Application Example

The power supply has been designed to cope with difficult operating environments such as wide voltage spikes seen with an engine cranking and also extremes of operation at low and high voltage operation. With the latest application developments there is a requirement for solutions to run on a much lower power budget and as a result Siretta has designed a family of extremely low power products. These products encompass an intelligent power management solution to shut down power to any non essential components and reduce consumption to an absolute minimum. When running the cellular engine in its lowest power state these devices can operate at less than 1mA whilst remaining connected to the cellular network. This means that they are always online and available to respond to incoming data socket connections whilst drawing substantially lower power than existing solutions.

The Siretta industrial low power modem family also support eSIM profiles to allow multiple SIM profiles to be stored within the cellular engine. This allows users to specify in real time which network they want to connect to and enables a global connectivity platform to take advantage of different pricing structures around the globe. Profiles can also be downloaded in to the unit once they have been shipped in to the field which means that there is no longer a need for an engineering visit.

The Siretta industrial low power modem solutions can be connected to most existing applications and remote equipment in the field can be configured to control and remotely access online resources with the minimal amount of effort using the serial interface and a standard set of AT commands.
