  2. Overview • Public WLAN • OBAN Approach • OBAN Service Examples • Opening WLAN • Opportunity for Service Providers • Deploy Now or Later? BroadBand Europe, Geneva

  3. Public WLAN BroadBand Europe, Geneva

  4. Today, there are many initiatives & approaches for offering public WLAN • Hotspots • Airports, hotels etc. • Municipal networks • Use mesh technology • Access points located on street furniture • WiFi sharing initiatives • Grassroots • Third party • OBAN (operator focus) BroadBand Europe, Geneva

  5. Some approaches have drawbacks • Hotspots • Limited availability (hotels, airports etc.) • Expensive • Municipal networks • Poor indoor bandwidth • Most WLAN usage is indoors! BroadBand Europe, Geneva

  6. OBAN Approach BroadBand Europe, Geneva

  7. The OBAN concept is to share residential broadband with the public using WiFi BroadBand Europe, Geneva

  8. There are many potential OBAN base-stations • High broadband penetration • Growing WLAN usage at home • Conveniently located where people live • OBAN service possible anywhere there are houses BroadBand Europe, Geneva

  9. Several OBAN-enablers have evolved • Standards • 802.11e available (QoS) • WiFi Pre-n product certification announced (range extension) • New WLAN products • Phones • Cameras • MP3 players • Video recorders BroadBand Europe, Geneva

  10. OBAN Service Examples BroadBand Europe, Geneva

  11. Many potential services VPN Connectivity VoIP Calls Video Uploads Photo Uploads Music Downloads BroadBand Europe, Geneva

  12. High-speed connection to the work place For business BroadBand Europe, Geneva

  13. Holiday photos or videos shared and secured For tourism BroadBand Europe, Geneva

  14. Music download For leasure BroadBand Europe, Geneva

  15. Cheap phone and video calls For communication BroadBand Europe, Geneva

  16. Opening WLAN BroadBand Europe, Geneva

  17. The resident has two main reasons to open bandwidth to the public • Community membership • Get access to resources of others in return for offering own • Financial reward • Service provider subsidy of access line or WLAN equipment • A share of revenue from public users • Preconditions • No impact on privacy & security • No impact on residential QoS • No legal implications BroadBand Europe, Geneva

  18. Opprotunity for Service Providers BroadBand Europe, Geneva

  19. ISPs currently waste most local-loop value ADSL Example (5 mbs capable copper) • 2 Giga Bytes download per month => less than 0.2 % downlink used • 99.8% for exploitation Local-loop capacity waste • Dedicated to one family • Not used most of the time • Bitrate is limited by Internet bottlenecks towards the server • Bitrate is limited by subscription Utilsation of local loop Good business to fill more seats BroadBand Europe, Geneva

  20. Cellular operators can benefit • Extend capacity at lower cost • Avoid public concerns about unsightly masts • Avoid costs of site acquisition cabling, maintenance • Use cheap base-station equipment (from the Internet world) • Off-load high-bandwidth traffic, low margin traffic • Enter new residential business BroadBand Europe, Geneva

  21. Deploy OBAN Now? BroadBand Europe, Geneva

  22. There are good reasons to deploy OBAN now • Leverages existing investments (local loop, WLAN) • Excellent indoor coverage • New WiFi products appear • First ventures on the market (Fon) BroadBand Europe, Geneva

  23. But, there are also reasons to wait • Not well understood technology • Small cell size and delay in pre-N standard for range extension • Unlicensed spectrum remains an issue for QoS due to inference • Economics of installing external antennas versus mounting on street furniture unclear • New WLAN terminal types appear, but usage habits not yet established (e.g. WLAN VoIP phones) • Cheap WLAN VoIP will cannibalise cellular BroadBand Europe, Geneva
