Abstract:

Ambient internet of things (IoT) is the network of devices which harvest energy from ambient sources for powering their communication. After decades of research on operation of these devices, Third Generation Partnership Project (3GPP) has started discussing energy harvesting technology in cellular networks to support massive deployment of IoT devices at low operational cost. This article provides a timely update on 3GPP studies on ambient energy harvesting devices including device types, use cases, key requirements, and related design challenges. Supported by link budget analysis for backscattering energy harvesting devices, which are a key component of this study, we provide insight on system design and show how this technology will require a new system design approach as compared to New Radio (NR) system design in 5G.

Introduction

The internet of things (IoT) market is a major source of revenue for future wireless technology. Moving beyond enhancement of the mobile broadband devices market that is supported by fourth-generation (4G) cellular technology, ultra reliable low-latency communication (URLLC) and machine type communication (MTC) service classes were also introduced in fifth-generation (5G) cellular technology, which target use cases requiring high reliability and massive deployment of smaller and cheaper IoT devices, respectively. Sixth-generation (6G) technology will further expand these market segments. The IoT market is expected to steadily grow from 2020 to 2025, and further increase is expected beyond that period at a higher rate. Building and commercial, health, agriculture, infrastructure, and industries are some of the key sectors targeted by the IoT market. Almost all sectors are forecasted to grow in the future, but infrastructure and health segments are expected to grow at higher rates in the future compared to others [1].
