Concert venues are extreme instances of traffic hotspots. Currently in concert venue settings, most operators use cellular solutions for voice and Wi-Fi for data. While this may be adequate for now, forecasts of exponential growth in user traffic (especially real-time video), this type of solution will not be sufficient in the future since Wi-Fi cannot provide Quality of Service (QoS) and the conventional cellular network will not have enough capacity. Let's consider a concert venue (e.g. Stadium) with a population capacity of 20000 to 90000. It's expected that people will be using smart devices with bandwidth-intensive applications such as mobile video. Hence, the forecast determines the traffic load will increase exponentially in the coming months. As a wireless operator, provide your recommendation to handle and maintain adequate QoS. Answer the following questions to provide the recommendations in a structured manner.
