Altair Ships IoT Chipset with Ultra-low Power Consumption to Support NTT DOCOMO’s Launch of Japan’s First eDRX Implementation

Demonstration Shows Power Reduction of up to 80%, in comparison with Altair Chipset using DRX, Significantly Extending Operation of Battery-Powered IoT Devices


HOD HASHARON, Israel – May 15, 2018 – Altair Semiconductor (, a leading provider of LTE chipsets, today announced that chipset interoperability testing on Altair’s ALT1160 Cat-1 chipset has been completed by NTT DOCOMO, INC., Japan’s largest mobile services provider. Altair has commenced shipping of the ALT1160, featuring Ultra Low Power Consumption optimized for battery operation, to support the first commercial implementation of extended discontinuous reception (eDRX) technology in Japan by DOCOMO.

Highlighting the significant difference between eDRX and existing DRX technology, DOCOMO  recently demonstrated its ability to significantly extend the sleep-mode duration of IoT devices, resulting in up to 80% power reduction and extending battery life by several times (in comparison with DRX). Operating on existing LTE networks, the technology will simplify the full deployment of long-term, battery-operated IoT devices such as smart utility meters and agricultural monitors. A variety of IoT Devices supporting eDRX are expected to be commercially deployed by Altair’s business partners.

eDRX substantially improves battery life by extending the sleep time between paging cycles of LTE-network connected devices. As a result, devices can remain ready to receive data for longer periods while maintaining full network accessibility.

“eDRX allows for unprecedented reduction in power consumption,” said Ilan Reingold,  VP Business Development and Marketing for Altair. “We are fully committed to continued development of a series of new chipsets to provide industry-leading power consumption rates that will enable exciting new devices for multiple IoT markets. We look forward to driving further innovation and enabling the expansion of cellular IoT business through our partnerships with leading Japanese mobile network operators. The new technologies of CAT-M1 and NB1 will improve this further.”
