NTT DOCOMO has completed the chipset interoperability testing of the Altair ALT1160 Cat-1 chipset for the first commercial implementation of extended discontinuous reception (eDRX) technology in Japan. Altair has commenced shipping of the ALT1160, featuring Ultra Low Power Consumption optimized for battery operation.
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. It allows for unprecedented reduction in power consumption.
