From the beautifully named city of Espoo, Finland, comes the news that seven Finnish WISPs are roaming freely across their networks starting in 2004: The networks include the cities of Hamina (operated by Haminan Energia), Lahti (Suomen 4G), Mäntsälä (Mäntsälän Sähkö), Porvoo (Porvoon Energia), Rauma (Rauman Energia), Vaasa and the Leppävaara area in Espoo (Netsafir) as well as Vantaa (Vantaan Energia). Radionet is providing the roaming technology.
Interestingly, TeliaSonera HomeRun, the largest trans-Scandinavian WISP, isn't part of this deal. HomeRun has extensive roaming agreements across Europe and elsewhere that require fees for their users when outside of the HomeRun network, but retain the single login, single bill convenience.
