At a Glance

The City of San Jose was able to design an enhanced wireless mobile broadband network using new technologies, innovative automatic tools and GIS data to facilitate the operational deployment on field.

Problem Addressed

With the use of new technologies providing ultra-broadband services using high frequencies, different challenges arise. The need for automatic tools to design such networks is compulsory to go to scale. An accurate description of the environment is also needed for wireless propagation, but also for inventorying urban furniture such as lampposts to host antennas.

San Jose, in collaboration with other stakeholders used/is using the outputs of this project to address this/these challenge(s).

Solution(s) Used

First Siradel collected LiDAR data on field to produce an accurate 3D model of the environment, using different sources, such as aerial images, aerial and street LiDAR data. Then Siradel provided a complete and automatic inventory of urban furniture based including lampposts, traffic lights, bus stops, etc. Using this realistic 3D environment, Siradel was able to design the network based on radio constraints in order to maximize the network performance and reduce the cost.

Outcomes

  1. Optimized network deployment providing a broadband service at a minimum cost

Something Unique

The uniqueness of this project is brought by the innovative tools and data developed and the innovative data collected.
