6G for Bridging the Digital Divide: Wireless Connectivity to Remote Areas
share
In telecommunications, network sustainability as a requirement is closely related to equitably serving the population residing at locations that can most appropriately be described as remote. The first four generations of mobile communication ignored the remote connectivity requirements, and the fifth generation is addressing it as an afterthought. However, sustainability and its social impact are being positioned as key drivers of sixth generation's (6G) standardization activities. In particular, there has been a conscious attempt to understand the demands of remote wireless connectivity, which has led to a better understanding of the challenges that lie ahead. In this perspective, this article overviews the key challenges associated with constraints on network design and deployment to be addressed for providing broadband connectivity to rural areas, and proposes novel approaches and solutions for bridging the digital divide in those regions.
