The purpose of this paper is to give a preview into the deployment and management of 5th Generation (5G) wireless network in Nigeria thereby addressing technical challenges of 5G deployment, assisting in the establishment of a 5G ecosystem, ensuring cost-effective implementation, management, and deployment in a timely manner in Nigeria. Data forecasting, and cost analysis were adopted for this study as the preferred tool to be used. It involved studying various network business deployment models, market demand and subscriber’s growth, and the cost for deploying 5G network equipment’s. The result showed that Infrastructure sharing based on Technology or based on Business/ownership are the preferred method for deployment cost reduction. Results obtained for subscriber’s growth forecast using optimistic, normal, and pessimistic scenarios are 171.52%, 163.35%, 155.19% respectively for the next 10 years. Also, deployment cost was observed to varies with population density and projected coverage area as for the case of Port Harcourt and Ahoada which are 12,069,144,108 dollars and 143,680,287 dollars, respectively. This work will contribute to the knowledge of Nigeria government in the Telecommunication sector, network operators to fast forward the rollout of 5G network in Nigeria and its management to reduced cost for the benefit of the Nigeria user. Also, this study adds to the body of knowledge by addressing technical issues, contributing to the formation of a 5G ecosystem, and maintaining cost-effective and speedy rollout of the 5G network across the country.

An Overview of the Deployment and Management of 5th Generation (5G) Wireless Network in Nigeria
This paper ex-rays the capacity of slaughter roundabout to address the traffic challenges by studying the traffic at the intersection. Slaughter intersection is one of the busiest intersections in Port Harcourt. Traffic volume count and analysis was carried out at the intersection and converted to equivalent Passenger Car Unit per hour (PCU/hr). The study revealed that, the intersection attracts a traffic volume of 3411 PCU/hr with a practical rotary capacity of 3209 PCU/hr. These capacities are about 13.7% and 7% higher than the recommended rotary capacity of 3000 PCU/hr given by the Indian Road Congress (IRC) making the present intersection inadequate and incapable of handling the present traffic set-up at Slaughter intersection leading to traffic problems. Further analysis on the four approaches revealed that they are undersaturated with degree of saturation of 0.31 (31%), 0.29 (29%), 0.45 (45%), and 0.23 (23%) for the North, East, South and West approaches, this is an average of about 0.53 (53%) below 0.85 (85%) of recommended traffic demand. Hence, the traffic situation experienced at Slaughter roundabout from field observation, were as result of illegal trading around the intersection, road user behavior, lack of pedestrian crossing facility, absence of pavement markings, lack of packing facility and not the flow from the approaches. The study therefore recommends an improved design of the intersection, parking facilities, pedestrian crossing facilities, a stop to illegal trading and markets around the intersection, provision of a flyover in the Trans-Woji section of the intersection.
