1st Workshop on 6G Ambient IoT for A Sustainable Environment

Track ID: Work-13



The ubiquitous sensor-rich mobile devices have been playing a vital role in the evolution of the Internet of Things (IoT), which bridges the gap between digital and physical spaces. However, high energy cost and short lifespan of these devices pose significant barriers to the spread of IoT applications. These concerns have drawn substantial attention from both academic and industrial sectors, emphasizing the need for sustainable IoT solutions. Recently, the concept of Ambient IoT has been proposed as a promising solution. relies upon energy harvesting as one of the key strategies for powering and transmit data using backscattering communications. Ambient IoT leverages energy harvesting and backscatter communication, allowing IoT devices to operate without batteries, and sustainably manage perception and communication within diverse 6G scenarios. The objective of this workshop is to discuss the networking and communication solutions for ambient IoT, as well as to demonstrate a cutting-edge hardware module and prototype for potential ambient IoT applications, and identifying an evolution path of Ambient IoT for the development of perceptible, controllable and sustainable future world.


Objectives and Motivation

Internet of Things (IoT) has become a pivotal driver in the growth of global industries. The proliferation of IoT devices creates significant issues of energy consumption for the six-generation (6G) scenarios. To address the issue, the low power networks diffuse in the industries, where the IoT devices are capable of harvesting energy from other sources. Recently, ambient IoT, in which a transmitter deliver data to the destination through backscattering ambient signals, becomes a crucial technology for low power networks. In contrast to earlier generations of IoT devices like Narrowband IoT (NB-IoT) and Long-Term Evolution Machine Type (LTE-M), Ambient IoT, which is proposed in 3GPP R18, is much smaller and less expensive. Without requiring a dedicated infrastructure, Ambient IoT devices harvest energy from the ambient environment, enabling two battery-free devices to communicate with each other by backscattering existing wireless signals. This innovative technique frees the IoT from the monetary burden of wired power connectivity or batteries, allowing a wide range of deployment of devices that were previously inaccessible. As a result, Ambient IoT has the potential to pave the way for a sustainable environment.

However, the integration of Ambient IoT into 6G communication systems still remain open issues. Both in academia and industry, the development of ambient IoT and backscattering communications is still in its infancy, and there are significant challenges to overcome. For instance, the communication ranges of Ambient IoT are still limited to a short distance and the energy harvesting efficiency does not come up to expectation. In addition, the PHY/MAC layers of ambient IoT require further research and designs. To address these challenges, our workshop hope researchers and engineers can share their initial yet promising ideas and engage in insightful discussions about Ambient IoT. Participants will gain insights into the challenges and opportunities associated with backscattering communication through interactive discussions, as well as the most recent advancements and trends in the industry. Additionally, our workshop will serve as a platform for participants to exchange experiences and viewpoints, and learn from each other's perspectives on Ambient IoT.

The objective of IEEE Internet of Everything (IoE) Special Technical Community (STC) is to significantly advance the key enabling technological areas, including sensing, data analytics, networking and security, in the context of IoT. IoE STC will also focus on the development of the IoE prototype and general platforms through collaborations between various institutions and industry. Therefore, IoE STC submits this workshop proposal to get involved in the WFIoT conference and keep paces with the cutting-edge innovations on ambient 6G IoT technology.



Our workshop aims to provide a comprehensive understanding of backscatter communication within the context of Ambient IoT, with a particular focus on its applications and underlying technologies. Ambient IoT has been confirmed as a key component of 6G, yet its technical details are still in the initial stages and require more extensive exploration. Therefore, our workshop can effectively gather cutting-edge technology of ambient IoT, better illustrate how ambient IoT can be utilized to address a variety of challenges and opportunities in the context of IoT, and inspire engineers to develop practical solutions for implementing such technologies. In our workshop, the innovations related to ambient IoT will be fully discussed, which can be summarized as follows,

  • The PHY layer techniques such as the energy harvesting, encoding, waveform design, modulation and interference elimination in the ambient IoT.
  • The MAC layer techniques such as resource scheduling.
  • The challenges of ambient IoT hardware design, especially the energy harvesting module design.
  • The demos and prototype for ambient IoT applications.
  • The frontier issues such as how to enhance the energy harvesting efficiency, communication range and data rate.

In all, our workshop will be dedicated in ambient IoT and highlight the technical innovations, thus forming a guidance towards the future development of energy efficient IoT for a sustainable life.
