CAT-1 LTE eDRX demonstrated on IoT devices
The announcement follows the chipset interoperability testing completion by NTT DOCOMO of the ALT1160 CAT-1 chipset from Altair.
Power saving mode (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 standards, enables further power improvement by allowing IoT devices to remain inactive for long periods and yet remain registered and accessible to network initiated communication. This reduces the amount of power required and extends battery life significantly.
“We are excited to test our LPWA IoT gateway with lower-category LTE technologies, for a solution that targets more than 10 years of battery life,” said Toshiyuki Futakata, Vice President and Senior Manager of NTT DOCOMO, Communication Device Development Department, Radio Access Technology Group.
“The CAT-1 standard doesn’t provide unique power reduction techniques. However, with Release 13, eDRX can exhibit very low current consumption on IoT devices,” said Eran Eshed, Co-founder and VP of Worldwide Sales and Marketing for Altair.
Altair’s ALT1160 CAT-1 chipset is designed specifically for IoT and M2M applications, such as wearables, vehicle telematics, smart meters and security applications. It features best-in-class power consumption, enabling battery life in excess of 10 years under specific use case conditions, and offers unique features such as enhanced security and a customizable application layer.
