On-Demand Networking for Ubiquitous Connectivity and Network Resilience: A Network-in-a-Box Solution

Recently, the wireless community has initiated research on the sixth generation (6G) cellular network for the next decade. The 6G visions are still under development but are converging toward ubiquitous, sustainable, and automated digital society. A network-in-a-box (NIB) is a portable and fully-fledged networking solution that has many potentials to stimulate 6G visions, especially for ubiquitous and resilient network connectivity. In this article, we highlight how NIB features suit 6G use cases and requirements and how it can be used for 6G communications. In addition, we discuss the challenges of the potential enabling technologies of 6G that can reinforce the NIB performance.
