BRINGING LIFE TO SMART CITIES
Source -udithawijesena. blogspot . com
Because of the heavy industrialisation and the intense urban migration the world has been facing in the last few decades , many cities have undergone unplanned developments . Although the quality of life has been significantly improved in the recent past , the above strategies have challenged the sustainable evolution of the densely populated areas . The concept of smart cities has emerged as a consequence of the attempt to solve urban problems around the globe .

With a multitude of next generation wireless technologies such as Li-fi , 5G , LoRa and network slicing being developed alongside the emergence of IoT ( Internet of Things ), the experience of large towns and cities is set to be enhanced considerably under the smart city concept . It is very crucial that these wireless technologies are developed promptly to provide the infrastructure for the diverse aspects of smart cities such as assured water and electricity supply , clean and renewable energy , smart grids , intelligent traffic control , efficient urban mobility and public transport , robust IT connectivity , waste management , safety and security of the citizens etc ..
The existing mobile and wireless infrastructure such as 3G and 4G which came before the real inception of IoT ( Internet of Things ) and smart devices lag considerably when it comes to the realisation of needs of the complex networks associated with smart cities . Therefore , these technologies should be developed further so that they are capable of catering for the various requirements effectively and efficiently . Network slicing is one of the key capabilities that will enable flexibility , as it allows multiple logical networks to be created on top of a common shared physical network , thereby supporting the numerous and different services envisaged in 5G . Network slicing is expected to play a critical role in 5G networks because of the diversity of use cases and new services that 5G will support . Here , a single physical network will be sliced into multiple virtual networks that can support different access networks . So , it can be primarily used to partition the core network .
Smart cities will rely on low latency to offer essential real time and
