Time-Reversal Wireless Paradigm for Green Internet of Things: An Overview

March 1, 2016

In this paper, we present an overview of the timereversal (TR) wireless paradigm for green Internet of Things (IoT). It is shown that the TR technique is a promising technique that focuses signal waves in both time and space domains. The unique asymmetric architecture significantly reduces the cost of the terminal devices, the total number of which is expected to be very large for IoT. The focusing effect of the TR technique can harvest the energy of all the multi-paths at the receiver, which improves the energy efficiency of the wireless transmission and thus the battery life of terminal devices in IoT. Facilitated by the high-resolution spatial focusing, the TR division multiple access scheme leverages the uniqueness of the multi-path profiles in the rich-scattering environment and maps them into location-specific signatures, so that spatial multiplexing can be achieved for multiple users operating on the same spectrum. In addition, the TR system can easily support heterogeneous terminal devices by providing various quality-of-service (QoS) options through adjusting the waveform and rate backoff factor. Finally, the unique location-specific signature in TR system can provide additional physical-layer security and thus can enhance the privacy and security of customers in IoT. All the advantages show that the TR technique is a promising paradigm for IoT.

Fixed 5th Generation Advanced and Beyond

whitePaper | September 20, 2022

One of the overarching goals of the ETSI Industry Specification Group (ISG) F5G on Fifth Generation Fixed Network is to establish a regular rhythm of evolution for the fixed telecommunications network. This technology enhancement corresponds to the series of generations defined for the wireless network. So far, F5G has published technical specifications on use cases, generations definition of fibre networks, architecture, and more. As it continues, these documents will be enhanced and revised to describe the fifth generation of fixed networks more fully. Therefore, we need to consider the evolution of F5G. This White Paper describes the drivers, dimensions, and technologies of the F5G advanced and beyond.
