No. 870: Reducing the data amount of Internet of Things (IoT) to one tenth (April 15, 2015)

Technology:
NEC developed a technology to reduce the data amount of IoT that has been increasing rapidly to one tenth. The company plans to start the substantiative experiment of this new technology within the year. IoT connects various devices like vehicles, industrial machines, and wearable healthcare terminals, and it is required to solve problems caused by rapidly increasing data amount.

The new technology can tell the difference between vehicles that travel over a wide range and electronic appliances that are used inside the house. The server studies the change of position information and communication frequencies and transmits only required amount of data with the best possible timing. For example, the new technology takes out heart rates from a sensor frequently, while it lengthens the measurement interval of equipment that examines the deterioration of bridges and tunnels. The data trading method became the standard of 3GPP that is the international standard project of mobile communication.

The Ministry of Economy, Trade and Industry reckons the number of devices connected by IoT was about 3 billion worldwide at the end of 2013, but it will increase to about 25 billion worldwide in 2020.

 IoT will connect more than 25 billion devices in 2020

NEC said, “This new technology will play an important role in IoT’s info-communication infrastructure and accelerate the provision of various solutions for such fields as traffic, energy, logistics, and medical treatment and healthcare. We will continue our utmost efforts for the development and practical applications of networks to build a secure, safe, efficient, and impartial social infrastructure.”
