San Francisco

“The Big Game has presented many opportunities for our city, including investments in critical infrastructure to meet the demands for higher-than-normal data usage,” said the city and county of San Francisco Chief Information Officer. “Extenet acted quickly to bolster wireless infrastructure to support the surge of cell phone usage, and the updated infrastructure will provide long-term benefits for future large-scale events and daily use in San Francisco.”


Connecting San Francisco With Distributed Networks

San Francisco’s rolling hills and notable architecture help draw people to Northern California’s epicenter, making San Francisco the most densely populated U.S. city after New York, with over 18,000 people per square mile. In 2016, Extenet designed and built an extensive distributed small cell network connected via a high-capacity fiber infrastructure throughout downtown San Francisco in preparation for football’s 50th championship game and the million-plus visitors it was expected to attract.

  • 995,000+ residents
  • 4G & 5G service-ready
  • Dense, high-capacity fiber backbone
  • Second-most population dense city in U.S. behind NYC


Working closely with city planners, SFPUC, MTA and other constituents, Extenet adhered to the aesthetic needs of the city and its residents during network design and construction phases. As an additional benefit, Extenet collaborated with the local utility company, Pacific Gas and Electric (PG&E), to create custom power meters integrated into the smart poles to monitor power consumption. The network will continue to deliver the city of San Francisco with high-speed wireless connectivity for years to come. With the emergence of 5G and the Internet of Things, advanced densified networks like this will be needed to reliably deliver the high-bandwidth speeds enabling those technologies.
