Altair and KDDI partner on LTE Cat-M demo

In Tokyo, Israeli chip company Altair Semiconductor teamed up with Japanese telco KDDI to demonstrate cellular LPWAN technology for IoT applications.
They demonstrated Cat-M – also known as CAT-M1 or LTE-M – using LTE extended discontinuous reception (eDRX) and power saving mode (PSM) settings in the presence of select media and industry executives.
"Cellular LPWA technologies are key enablers for the proliferation of IoT applications and use cases," said Hiroshi Tsuji, general manager at 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 realising the IoT vision."
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 communications. This reduces the amount of power required and extends battery life significantly.
"Long battery life is a very important feature for many IoT use cases," said Eran Eshed, co-founder of Altair. "Altair's chipsets set the industry benchmark for ultra-low power consumption. We are excited to cooperate with a leading carrier such as KDDI in an effort to commercialise this unique capability for the benefit of users and organisations in Japan and worldwide."
Altair Semiconductor produces single-mode LTE chipsets. Its portfolio covers the spectrum of cellular 4G market needs, from supercharged video-centric applications to ultra-low power, low cost IoT and M2M. The company has shipped millions of LTE chipsets, which are commercially deployed on LTE networks including from Verizon Wireless, AT&T, Softbank and Korea Telecom.
