mmWave technology: An impetus for smart city initiatives

摘要

The sub 6 GHz bands are vastly congested in many communication and non-communication applications and in the future environment of Networks will require to meet exclusive requirements of spectrum with complete user satisfaction demanding improved network efficacy and its ability to meet increased demands and capacities in enclosed spaces with dense inhabitation. Cities will need to induct and adapt technologies for monitoring resources viz water, energy, monitor movements of goods and assess security of people while ensuring that the quality of life is maintained below the threshold of human interference. In such an environment of the future 5G networks and communication systems, devices such as sensors in this region of the spectrum will assume importance as it inherently provides large bandwidths, efficient spectrum management for deployment of pico-nets over small community areas. The deployment of 5G network will provide a high speed low latency network on which Intelligent Transport Systems can be fielded for accident avoidance and mitigation of traffic congestions and making smart city functions fairly autonomous. Further it is relatively easier to sense range, velocity and angle of detection with great accuracy and also provide the robustness for continuous operation for various indoor and outdoor applications. In all these features a large array of sensors deployed will need constant and accurate data flow which will be feasible on future 5G networks based on mm Waves. The paper aims to identify the areas in which mm wave spectrum and devices can be gainfully utilized in the backdrop of smart cities of the future.
