"The San Francisco Bay Area is the world's high-tech center, and now anyone traveling through SFO can access their e-mail, shop, and conduct business on the airport's Wi-Fi service free of charge," Newsom said in a prepared statement.
For the past several years, airport officials have provided wireless Internet through a fee-based service.
Airport officials decided to adopt the free service, originally scheduled to start Sept. 1, after the contract with their vendor expired earlier this year.
"For the past few years our internal surveys have shown that our customers wanted free Wi-Fi, and we're now offering that because SFO is committed to providing first class customer service to everyone who passes through our gates," Airport Director John Martin said in a prepared statement.
