• Open and free wireless internet access in public
places should be part of municipal infrastructure
• Provide coverage where it matters
• The network needs a committed owner
•J i f
Join forces via a public-private partnership
i bli it t hi
• Municipalities – present the challenge!
• Share your WiFi infrastructure
• Incorporate telcos via a concept like panOULU subscription
• Make your network open
