  1. Open Networks - Session I Introduction to Open Networks and WLPR.NET Matti Juutilainen Matti.Juutilainen@lut.fi Lappeenranta University of Technology Communications Engineering

  2. Agenda • The evolution of wireless LANs • WLAN network models & comparison • Wireless Lappeenranta network model WLpr.net • Influences of open networks • Conclusions

  3. Company ISP ISP Company Intranet Closed Access Network Closed Access Network Closed Access Network ISP network Internet The Evolution of Wireless LANs Wireless ISP network + manageable, easy planning – high building costs, interference – closed, limited possibilities – roaming requires co-operation

  4. Internet ISP ISP Community Network ISP ISP ISP Community network The Evolution of Wireless LANs Community network + likely to spread, lots of users + shared building costs + public, wide possibilities (users, services, …) + easy roaming – hard to manage – difficult to plan (access point locations) – coverage area – Internet-access?

  5. Open Access Network Company ISP ISP Company Intranet Operator Interface Internet Lappeenranta Model The Evolution of Wireless LANs Public multi-ISP network + manageable, easy planning + low building costs, less interference + public, wide possibilities + easy roaming + lots of users + local services – complex user routing and authentication

  11. Influences of Open Networks • Local influence • Influence on • Internet Service Providers (ISPs) • Service providers • End users • City and the local area • Network manager

  12. Conclusions • WLAN networks are affordable and popular for the last mile. • WLAN technology is not yet mature • Need for speed, reliability, security, range, lower costs, interoperability, QoS etc. • Also other competing/supporting wired network technologies (Fiber, Ethernet, …) • New network models are emerging • Community networks • Public multi-ISP networks • Demand for public and affordable local networks.

  13. Conclusions • Commercial usability is vital. • Different network options: • Commercial single-ISP networks • Advantageous only for the ISPs? • Community networks (Seattle Wireless etc.) • Commercial usability/reliability? • Public access systems • StockholmOpen.net • Wireless Lappeenranta • HelsinkiOpen.net • Regional networks • In practice, most of the networks are a combination of previous options.

  14. Conclusions • Publicity will be in a key role • Public access networks will be strong. • Publicity offers new opportunities for everyone • Internet Service Providers (ISPs) • Service providers • End users • Neutral network manager • City and the local area • Need for services and content!
