The promise of 5G network has been lauded for a long time, but it is now finally becoming a reality. 5G was finally introduced into the market after years of creating buzz about the lightning-fast speeds offered by the latest generation of mobile network technology; and this was followed by massive rollout and deployment in 2020. The introduction of 5G is going to transform the way we connect in 2021 and beyond. It will influence the use of internet of things (IoT), mobile devices and sensor technologies in critical industries including smart cities, automotive, industrial, communication, wearables and consumer electronics. 5G is set to usher in a new phase of better and more effective connection and service. Though the arrival of 5G technology and its futuristic future applications has been received with great excitements and high hopes, it is important to note that the 5G implementation is still in its infant stage. Therefore, it is believed that the current excitement about its transformational impact is too early as there is a great deal of work that is required before the network can begin to deliver on its promises. This paper examines the possible future applications of 5G network, where the technology is today, its implementation issues, and what the industry is doing about it.
