The ZETA-NLP-LTEM (GL) is a cutting edge, extremely low power industrial modem. It will connect equipment to the new global LTE CAT-M1 and CAT-NB1 networks as they become available also providing connectivity to the existing global 2G / GSM cellular network. The modem is able to operate in an extremely low power state which makes it ideal for use in industrial IoT applications today and for long term future developments.
The unique feature of the ZETA-NLP-LTEM (GL) allows it to run in an ultra low power state due to its intelligent power saving design. Additionally the range offers interface options including legacy RS232 for connection to existing equipment and a high speed USB interface.
The powerful C development environment reduces redundancy and lowers system component costs, allowing developers to maximise the power of their application directly on the device and eliminating the requirement for an external microcontroller. As a result the ZETA-NLP-LTEM (GL) lends itself to rapid proof-of-concept developments with minimal investment, providing fast time to market and maximum scalability.

| Normal power mode with registered IP address in idle state | 15.9 mA | 9.5 mA | 5.56 mA |
| Normal power mode with IP socket connected and transmitting data | 126.7 mA | 81.9 mA | 42.4 mA |
| Normal power mode with active data call in progress | 205.5 mA | 128.2 mA | 67.4 mA |
Using the low power function on the Siretta Industrial Modem allows the device to consume very little power in its idle state. The modem will remain in the idle state for the majority of time and when there is data to send, the modem will enter normal power state for the duration of the transmission. This can reduce the overall power consumption in some applications by up to 97%.
