Vonage said it will offer Wi-Fi access to its VoIP service in select U.S. cities after inking a three-year deal with EarthLink. Financial terms were not disclosed.

Under the deal, Vonage will buy Internet access from EarthLink on a wholesale basis, where EarthLink will build, own and operate municipal Wi-Fi networks.

Vonage will offer the resulting wireless service under its own brand.

Later this year, Vonage said it plans to introduce new hardware to support the partnership with EarthLink, including a wireless modem unit. Later on, Vonage plans to offer a Wi-Fi phone, as well. 

Presently, EarthLink has Wi-Fi contracts in Philadelphia, Pa.; Anaheim and Milpitas, Calif.; and New Orleans.
