The fifth-generation mobile network has been developed and standardized with an intention of exploring the market beyond 2017. The question was to study the distribution strategies to fill out the needs of this strong network introduced for real-time feedback. Mobile operators proposed five alternative network architectures to 3GPP. The response to the question was to carry out the first distribution strategy which is Non-Standalone New Radio (NSA NR) in 2017 followed by a Standalone New Radio access network that was standardized in 2018. This study analyzes the distribution strategies of the 5G New Radio (NR) network, main technologies, benefits and drawbacks and compares NSA NR and SA NR distribution modes in terms of coverage, network capability, the inter-working which is between 4G and 5G, complexity and network distribution cost in Rwanda. This also highlights the potential challenges to implement 5G especially in Least Developed Countries.

Micro Operators have been also used to accelerate the deployment for new entries and presented some challenges where the proposed solution for them has been the planification of a huge amount of economic resources as well as skilled manpower. The study concluded that the reliable and efficient distribution strategies of 5G NR Networks will be based on Non-Standalone (NSA), Standalone (SA) and the Micro Operators considerations to accelerate its distribution not only in global context but also in Rwanda.
