Rephrase: There are efforts underway to turn entire cities, such as San Francisco

Please rephrase the paragraph bellow for simply understanding.

There are efforts underway to turn entire cities, such as San Francisco, Portland, and Philadelphia, into big wireless hotspots. Many of these plans will offer free, ad-supported service or ad-free service for a small fee.

A question first: what are these "planes"? Should it be "plans"? Even then the sentence would be odd, but not as odd as it is now without context.
