This morning, OPPO Research Institute followed the previous "6G AI-Cube Intelligent Network" white paper, and officially released the "Zero Power Communication" white paper that is closely related to the field of communication technology. Based on the current unmet needs of Internet of Things communication, the white paper "Zero Power Communication" for the first time explains the technical positioning and development prospects of zero power communication technology in detail, and gives direction guidance for the coexistence and integration of its coexistence and integration with future communication networks.
In the case that the vast majority of electronic devices still rely on batteries for energy supply and energy supply needs to be improved in many aspects, OPPO closely follows the theme of the times, discovers the energy supply problems of electronic devices and further proposes the white paper "Zero Power Communication", puts into practical action to build a zero power communication system, and promotes the popularization and landing of "zero power communication technology", which confirms OPPO's continuous exploration and efforts in the field of communication technology.
In the near future, IoT devices will be able to directly obtain energy through Bluetooth, WiFi, and mobile phone signals, so as to achieve smaller size, longer life, and lower cost. The loss-proof electronic tag used to track the location of the item will not require battery replacement, each endangered migratory bird can carry ultra-remote monitoring equipment, and the number of batteries that cannot be environmentally degraded will be greatly reduced, which is the description of this communication system in OPPO's "Zero Power Communication" white paper.
Zero-power communication terminals exist in the form of electronic tags, pasted on keys, glasses and other small items that are easy to lose, which is convenient for quick search of items, with no battery, extremely small size, ultra-low power consumption, ultra-low cost and other characteristics, which can effectively reduce the maintenance costs and pollution hazards of current micro electronic products.
So far, almost all electronic devices on the market have relied on battery capabilities. There are problems in many aspects of battery energy supply, such as overall size, production cost, service life, ease of use, recycling, etc., and the size is large, the power consumption is high, and the cost is high. In addition to the battery itself, there are also many problems in passive communication technology, passive communication technology represented by radio frequency identification (RFID) technology, short communication distance, high cost, the need for additional radio frequency sources, etc. has always been a problem on the vent. In the harsh environment of the industrial Internet, low-cost high-capacity logistics and warehousing scenarios, low-cost and low-power smart home and extremely small size wearable and other special applications, there are still great challenges.
In terms of charging to obtain energy, the zero-power communication system can enable the device to directly complete energy acquisition through Bluetooth, WiFi, and mobile phone signals, without charging or replacing the battery. In addition, zero-power terminals can also reduce costs and increase efficiency for vertical fields such as intelligent warehousing, intelligent logistics, and smart agriculture. In terms of communication technology, unlike traditional passive communication technology, zero-power terminals can collect RF energy from wireless signals emitted by existing environmental RF sources (such as TV towers, FM towers, cellular base stations and WiFi access points), and backscatter communication is achieved by modulating incoming wave signals.
At the same time, the white paper formulates a combination of cellular-based, side-line communication, and hybrid cellular-based communication for zero-power communication according to different deployment scenarios and usage needs. Among them, the cellular-based zero-power communication system is suitable for industrial Internet of Things scenarios with harsh environments, huge quantities and high maintenance costs, reducing manpower and equipment investment; side-line communication between terminals meets the needs of low-cost short-distance communication, and realizes intelligent reading, environmental monitoring, intelligent control and other functions in smart home and wearable scenarios; in addition, the two systems can also be flexibly adapted and combined to create communication conditions for more application scenarios.
Tang Hai, chief 5G scientist of OPPO, said: "From 1G to 4G, it has undergone four technological changes of analog, digital, data and broadband, and the pursuit of higher transmission data rate is the theme of "unchanged" mobile communication technology. But as we move into the next decade, the industry as a whole will need to rethink what the new needs and drivers will be? OPPO believes that in addition to pursuing higher data transmission rates, next-generation communication technologies should also focus on how to allow more people to enjoy the convenience of technology and create positive and more sustainable values for society. Zero-power communication technology can help the micro-electronic products on the market to get rid of the battery, greatly reducing the maintenance cost and pollution hazards of the terminal, and is one of the core technical solutions that OPPO pays attention to in the B5G/6G stage. ”
In terms of zero-power communication, OPPO is not the so-called "verbal talk", and has successfully built a zero-power communication system and completed the verification of the principle of zero-power communication technology. In addition to technical self-research, OPPO also leads the research proposal of zero-power communication in the international standard organization 3GPP as the main standard promoter, contributing to the communication industry ecology. At the IMT-2030 "6G Vision Outlook" seminar that ended in September 2021, OPPO initiated and organized a zero-power communication theme forum, inviting schools and enterprises to discuss the application scenarios, technical requirements and key technologies of zero-power communication.
In oppo Research Institute's first 6G white paper, "AI-Cube-Enabled 6G Network Architecture", OPPO pointed out that 6G will reshape the way people interact with AI, so that convenient AI can be popularized and become an infrastructure that can be used by everyone. At present, the intelligent terminal in our hands will become an important participant and user of AI, and the user's terminal device can call and load AI algorithms in different scenarios, bringing users a new immersive intelligent experience, and also delivering data and feedback for AI, and improving the AI model, and ultimately achieving a win-win situation.
Looking at the 6G era, OPPO believes that zero-power communication will be combined with hot technologies such as symbiotic communication, intelligent hypersurface, artificial intelligence, and non-orthogonal multiple access (NOMA) to play the full potential of the system.
