Programmable Modem

This modem is designed especially for M2M applications. As the device is programmable, you can transform it into a standalone product or can use it to reduce the complexity of your solution as well as time to market. The modem can deliver instant wireless connectivity to multiple applications and allow you to integrate features such as Data pre-processing, SMS, Date operations, etc to your cloud server via TCP-IP.
Our programmable Modem is ideal for application in diverse areas such as Automatic Meter Reading (AMR), GSM-based pump automation, Fleet/Traffic Management (with optional GPS integration), Security Systems, Remote Data logging and reporting, System to monitor data over the Internet, Remote monitoring of Vending machines.

The modem is a plug and play device making its installation and configuration very simple. It is encased in a rugged aluminum alloy extrusion casing with good aesthetics and surface finish to withstand the toughest field environments. The open interfaces and AT commands can embed and run your applications very efficiently. With its proven technology, the modem can be relied on for enduring and dependable performance.

“The Internet of Things is removing mundane repetitive tasks or creating things that just weren’t possible before, enabling more people to do more rewarding tasks and leaving the machines to do repetitive jobs.”
