AT&T said Tuesday it will expand its fiber network to Chicago, as it competes with Google and others to provide super-fast Internet speeds across the country.



AT&T said its fiber network can deliver speeds of up to one gigabit per second, about 100 times the national average. At that rate, a user can download 25 songs in one second.



The Dallas-based company announced in April that Chicago was one of 100 cities nationwide it was considering for the expansion of its fiber network. The other candidates in Illinois were the suburbs of Des Plaines, Glenview, Lombard, Mount Prospect, Naperville, Park Ridge, Skokie and Wheaton.



AT&T did not provide information Tuesday about whether those suburbs will also receive the fiber network.



In the race to get cities super-fast Internet, the question is whether the service will be affordable. AT&T said it will announce pricing and availability in the Chicago market at a later date.



In Austin, Texas, where AT&T has installed its fiber network, the one-gigabit-per-second service, is available for $70 a month, according to published reports.
