5G has the potential to transform New Zealand cities and towns forever. Councils and citizens will be able to better manage resources, reduce costs and increase the quality of life. A smart city can collect and analyse data from sensors and video cameras, with a city operator deciding how and when to take action. Some actions can be performed automatically. For example, a public wastebin can contact the city for service when it is near capacity instead of waiting for scheduled pickup. Cities can generate revenue with demand-based parking and reduce parking space search time. Smart street lighting can lower energy consumption by only illuminating lights when there are vehicles or pedestrians in the vicinity. Infrastructure maintenance will be on an as-needed basis, dramatically cutting costs.
