EarthLink will offer a package to wireless ISPs, operators who want to follow in their footsteps: This ISP Planet article says EarthLink will require roaming and some unspecific conditions for its franchisees, and will request (but not demand) a right of first refusal to buy should the WISP choose to sell its network. EarthLink will provide its architecture plans, its volume equipment pricing deals, and can offer EarthLink products and support. There's no revenue share, an EarthLink exec said at ISPCON last week.
EarthLink also said it was looking to rollup smaller WISPs into its footprint, although it would retain local brand names.
