The document discusses how Streetline Networks and Dust Networks improve city efficiency and citizen happiness by reducing traffic and pollution. One of the challenges addressed is the issue of parking. It is estimated that 30 percent of urban traffic is caused by drivers searching for parking. The solution proposed involves collecting real-time data from individual parking spaces using wireless technology. The solution needs to be battery-powered and resilient, as wireless signals are affected by vehicles on the street. Additionally, the solution should be easy to deploy, scale up, and configure.
