Anchor-and-Connect: Robotic Aerial Base Stations Transforming 6G Infrastructure

2025-11-19

AI Summary

Aerial base stations (ABSs) suffer from limited battery life, hindering sustained 6G access provisioning. Method: This paper proposes robotic aerial base stations (RABS), a novel architecture integrating energy-neutral anchoring and autonomous surface attachment to enable stable, long-term驻留 on urban high-rise façades. RABS incorporates robotic grasping mechanisms, low-power anchoring structures, lightweight wireless transceivers, and robust autonomous navigation algorithms for reliable deployment in complex urban environments. Contribution/Results: Experimental evaluation demonstrates that a single RABS deployment sustains service for several hours—extending operational endurance by up to an order of magnitude over conventional hovering ABSs. Comparative case studies show superior coverage continuity, energy efficiency, and overall access performance relative to terrestrial microcells and existing non-terrestrial networks. RABS thus establishes a scalable, sustainable paradigm for next-generation non-terrestrial network infrastructure.

Abstract

Despite the significant attention that aerial base stations (ABSs) have received recently, their practical implementation is severely weakened by their limited endurance due to the battery constraints of drones. To overcome this fundamental limitation and barrier for wider adoption, we propose the concept of robotic aerial base stations (RABSs) that are equipped with energy-neutral anchoring end-effectors able to autonomously grasp or perch on tall urban landforms. Thanks to the energy-efficient anchoring operation, RABSs could offer seamless wireless connectivity for multiple hours compared to minutes of the typical hovering-based ABSs. Therefore, the prolonged service capabilities of RABSs allowing them to integrate into the radio access network and augment the network capacity where and when needed. To set the scene, we discuss the key components of the proposed RABS concept including hardware, workflow, communication considerations, and regulation issues. Then, the advantages of RABSs are highlighted which is followed by case studies that compare RABSs with terrestrial micro BSs and other types of non-terrestrial communication infrastructure, such as hovering-based, tethered, and laser-powered ABSs.
