Free Wi-Fi is coming to 31 San Francisco parks, thanks to local tech giant Google picking up the massive tab.

City supervisor Mark Farrell announced the news on Wednesday. All of the parks, plazas and open spaces are expected to be fully connected by spring 2014, with installation beginning this December.

While it will bring free Internet to thousands of San Francisco residents and visitors, the move doesn't come cheap: Google is paying $600,000 to cover the necessary installation, hardware and maintenance costs.

Why? It's a smooth PR move to be sure, but Google's community affairs manager Veronica Bell said the company hopes it has larger implications than just a positive news splash.

"This network will make the web more accessible than ever for many San Franciscans — all they have to do is visit their neighborhood park to get online," she said. "We hope that free Wi-Fi will be a resource that the City and other local groups will be able to use in their efforts to bridge the digital divide and make their community stronger."
