Radio links without infrastructure refer to wireless communication systems that establish direct connections between devices or locations without the need for intermediary infrastructure such as cell towers, fiber-optic cables, or satellites. . When a mobile device communicates in a cellular network, data is typically going in both uplink (UL) and downlink (DL) directions to a transceiver entity generally known as a basestation. In this blog post, we explore how these systems work, their applications, and their benefits. What Are Radio Links Without Infrastructure? Radio links. . Mobile telephone base stations and satellite telephones are of major importance, but they have their limitations in terms of cost, construction time, and access on a large scale. A Swedish researcher presents a program that runs on telephones and can deliver messages even when the infrastructure for telecommunication. . High-altitude platform station (HAPS) systems can be used to provide both fixed broadband connectivity for end-users and transmission links between the mobile and core networks used for backhauling traffic. They're called non-terrestrial networks and are expected to roll out in the early 2030s. Researchers at the King Abdullah. .
