OPPO has announced that they are working with partners in the industry to make Zero-Power Communications devices. The company wants this to become a core part of next-generation communications technologies.

Zero-Power Communication devices are battery-free, highly compact, ultra-low cost, and ultra-low power consumption. This in turn reduces waste and pollution associated with current electronic devices.

In its “Zero-Power Communications” white paper, the company examines the technical positioning of Zero-Power Communication technology in the context of current unmet demand in the IoT space while outlining a future roadmap for the technology to develop in coexistence with other communications systems of the future.

Zero-Power Communication technology avoids the need for batteries by harvesting ambient radiofrequency energy in the environment to generate power, resulting in highly compact, efficient, and low-cost devices. Such properties have benefits in commercial applications such as warehousing, logistics, and agriculture and in wearable devices, smart homes, and other cutting-edge consumer applications.

“From the first to the fourth generations of mobile telecommunications technology, the telecommunications industry has gone through four technological leaps — from analog to digital, to data, and finally to broadband. Each of these leaps has been designed to deliver faster data transmission rates; however, over the next decade, looking at 5G technology, we believe that technology should evolve to deliver greater convenience and sustainable value for society as a whole. Zero-Power Communications technology offers a means for electronics manufacturers to remove batteries from their products, reducing their costs and environmental impact in the process. As such, Zero-Power Communications is one of our core focus areas as we move into the B5G/6G generation,” said Henry Tang, OPPO’s Chief 5G Scientist.

Unlike the traditional method, Zero-Power devices can harvest ambient radio signals broadcast from sources such as TV towers, FM radio towers, cellular base stations, and WiFi access points as their source of power. After harvesting the energy from existing radio waves, the device can modulate ambient radio signals with its own information and transmit these signals outwards in a process known as backscattering communication.

OPPO has already successfully built its own Zero-Power Communication system and demonstrated the feasibility of the concept as a viable approach to future communications networks.
