Altair, KDDI demonstrate cellular LPWA for IoT

Altair Semiconductor has teamed up with Japan’s KDDI to demonstrate CAT-M (a.k.a. CAT-M1 or LTE-M), the new Release 13 in conjunction with ultra-low-power consumption, using LTE extended discontinuous reception (eDRX) and power saving mode (PSM) settings. The demonstration took place in Tokyo on December 9, 2016.

“Cellular LPWA technologies are key enablers for the proliferation of IoT applications and use cases,” said Mr. Hiroshi Tsuji, General Manager, Product and Device Technology Department of KDDI. “We at KDDI have a longstanding partnership with Altair, which started with CAT-4, extended to CAT-1 and is now focused on Cellular LPWA technologies. Altair’s ultra-low power consumption architecture and early market leadership are very valuable for KDDI in realizing the IoT vision.”

“Long battery life is a very important feature for many IoT use cases,” said Eran Eshed, Co-founder and VP of Worldwide Sales and Marketing for Altair.

PSM, as specified by 3GPP Release 12, allows devices to connect to the network only as needed, preserving battery life by remaining in sleep mode. Similarly, eDRX functionality, part of the new Release 13 standard, enables further power improvement by allowing IoT devices to remain inactive for long periods, yet remain registered and accessible for network-initiated communication. This reduces the amount of power required and extends battery life significantly.
