NEC technology reduces network load for operating IoT devices - Optimizing control signals reduces the load for carrier networks -

*** For immediate use April 7, 2015

Tokyo, April 7, 2015 - NEC Corporation (NEC; TSE: 6701) has developed a groundbreaking new communication technology that significantly reduces the number of control signals used for operating Internet of Things (IoT) devices, thereby reducing the carrier network load required for IoT devices to perform.


This technology adjusts the control signals that are sent between carrier networks and IoT devices based on factors such as the transmission interval and the speed of the IoT device. This is done by recognizing the communication and mobility characteristics of each IoT device and implementing control based on the communication status and position of each IoT device.


Furthermore, the technology employs 3rd Generation Partnership Project (3GPP) international standards that NEC has helped promote throughout the world, enabling compatibility on a global scale.


Mobile networks are currently designed to suite daily human behavior, such as carrying a mobile phone, where control signals are transmitted to meet the communication needs between a device and the carrier networks. However, IoT devices operate differently than humans, such as smart meters that repeatedly start and stop communication and automobiles that rapidly move between network areas, which generate a large number of unnecessary control signals. This increases network load and prompts concerns over reduced network reliability.


“This technology lowers network load by reducing the number of control signals for IoT devices to approximately one-tenth that of previous levels while maintaining highly reliable mobile networks,” said Motoo Nishihara, general manager, Cloud System Research Laboratories, NEC Corporation.


“In the future, this technology can be used to optimize the exchange of control signals for the wide range of products and applications that are expected to connect to carrier networks, including automobiles, smart meters and other innovative IoT devices that can be harnessed to create new businesses and services.”
