In addition, the improvement of the present waste management systems is made possible with 5G technology. Smart bins that use sensors can determine the fill level of the bin in real time, thus allowing the waste management services to plan for better efficiency in collection routes and frequencies. This helps save costs since it will not require the collection agency to make visits due to full bins not required to be collected at all. 5G allows smart streetlights that are prepared with motion detectors and cameras to follow the movements of pedestrians. These lights can brighten where there are individuals on the road and dim where there is no one on the road, hence conserving energy. Therefore, the upgrading of the network through 5G is central to the improvement of the urban structures into technology-intensive structures that create favorable living standards for the residents.
Intelligent Transportation Systems
Transportation is an essential aspect of running society in the urban areas due to the high population density in such regions. V2X communication, often known as vehicle-to-everything communication, is enabled by 5G due to the high volumes that 5G transmits data with little or no latency. The capabilities that can be described include sending and receiving information about traffic and road conditions, weather conditions, and possible dangers to traffic, etc., to facilitate better decision-making and adaptation by one vehicle to the other and the road environment. For instance, if a vehicle sees that there is a change in traffic pattern, then it is able to notify other vehicles in the vicinity of this change and then recommend the best routes, hence reducing traffic jams and also preventing the happening of accidents. In addition, the technology of 5G provides the feasibility of the advancement of self-driving cars, where the vehicles depend on immediate feedback to avoid a crash in congested cities. New rapid communication ensures the ability to receive updates on the maps, work with automated traffic control systems, and respond quickly in case of some emergencies. This is because today they have embraced electric and autonomous vehicles, hence employing 5G technology becomes vital for better and more efficient working of the cities. In addition, it is worth noting that various aspects of the public transportation system may be improved by 5G as follows. Passengers can have real-time updates of bus and train movements, hence enabling them to arrange for their travel properly. By so doing, it can also provide users with arrival time, number of seats, and any service cancellation, which are key aspects that can increase user satisfaction.
Enhanced Healthcare Services
The healthcare sector is on the cusp of the revolution because of the integration of 5G in the smart cities. Telemedicine increased during the COVID-19 crisis and can be enhanced with the help of 5G that provides ultra-reliable low-latency communications. It also enhances the possibilities of competent healthcare practice because patients can receive consultations from healthcare providers virtually, without any disturbances. It can also be used with wearable health devices through 5G applications to consistently log patients’ vital signs and health parameters to the care providers. In patients with such diseases, such constant check and control may mean early treatment and necessary care, not requiring frequent hospitalizations. Hence, through the application of the incorporation of 5G technology, the implementation of surgery through telemedicine platforms is practical. Specialists can implement various procedures with the help of robotic systems that are based on many kinds of communication; hence, specialists can effectively act with patients even if they are situated in remote zones. This capability helps to widen the people’s access to such techniques and interventions of a healthcare professional. In addition, the adoption of telemedicine in hospital settings also allows for patient smart management by use of real-time data for management of resources and effective time segmentation to avoid long waiting times for patients. Because of this, 5G technology analyzes patient statistics and the number of health care professionals to improve the functionality of hospitals and thus, improve health care delivery.

Energy Efficiency and Sustainability
Environmental sustainability is an overarching concept for smart cities, and 5G technology specifically enhances energy saving and thus protections of the environment. Smart grids via the 5G network can track the energy usage continually and let the cities manage resources efficiently. For instance, smart buildings with sensors through 5G can regulate the heating, cooling, or lighting systems by detecting who is in the building. Thus, the automation helps to reduce energy inefficiency and greenhouse gas emissions with reference to sustainable development objectives while at the same time cutting down operational expenses. Moreover, 5G technology improves the control of the systems of the recharging stations of electric vehicles connected with the smart grid. These charging units might have a capability to connect with the electric vehicles to synchronously plan charge timings to prevent overloading of the electricity supply. In addition, 5G makes the environmental monitoring within the urban area easier to execute. It is noteworthy that sensors are capable of measuring the quality of air, noise levels, and temperature in the city, while officials need such information to address the key issues affecting the environment. Real-time data also assists cities to react quickly to pollution or any other predetermined environmental threats to provide a healthier atmosphere in cities. It also helps the city planners analyze the data produced by IoT devices to make proper decisions on the planning of the city and the use of resources. The idea of using big data in decision-making processes helps to nurture city development that is more sustainable and is capable of withstanding the effects of climate change.
Challenges and Considerations
Despite this, there are several challenges and factors that have to be considered in the context of applying 5G technology in smart cities. Yet another issue that can be mentioned when it comes to 5G is the cost of creating the required infrastructure to support this connection. Cities cannot force companies to deploy small cell towers and fiber optic networks where cost-effective to the companies, but they must make sure that such technology reaches the unserved areas so as to afford the citizens equal opportunity. Another important concern is cybersecurity as the cities grow integrated. 5G is associated with high-risk factors when devices are connected, especially with the growth in internet usage nowadays. These city structures need to have strong security measures in place given that such cities will handle residents’ data. This includes the use of security features such as encryption, timely updates of software, and constant assessments of risks in the networks. That is the reason why quantity 5G technology requires high acceptance and understanding among the public domain. Members of the society should be made aware of not only the benefits that come with technology and 5G but also the risks, such as the risks it poses to their lives. This means that anyone who would embark on community engagements willingly and proactively to help introduce the technologies will be well taken with the community. Last but not least, the equity factors have to be looked into. With cities now adopting smart technologies, it was important that all populations within the cities get to benefit from smart city applications irrespective of the population’s ability to pay. Another measure that needs to be taken on the way to ensuring that smart cities are for everyone is to deal with the digital divides and also invest in the training programs for those who do not understand how to handle technology.
