Atlanta has been a laggard in major airport Wi-Fi coverage: They've been discussing airport access as part of a broader citywide Wi-Fi service since 2004. The airport was supposed to be unwired this spring, but let's not blame them for ambitious plans. The company that was to provide this service still says coming soon on their Atlanta FastPass page, the name for this project.
The airport will offer service on a wholesale basis to providers which will resell it or include it to their customers, an approach which seems to offer the least friction.
The service will cost $3 million to install. The article doesn't mention anything about the larger Atlanta project.
