Chooses SSID for you General Solution Sets

5. doc.: IEEE 802.11-09/0830r1 Submission Advertise the easement. Wi-Fi provider decides which Public Easements he wishes to enable (e.g., texting or multimedia). Texting or multimedia is advertized with SSID (eg, “PublicEasement”) Bandwidth/size/location is shaped at the discretion of the access point Provides Public Easement through NATed last leg Wi-Fi connectivity The provider protects itself from abuse of the easement Providing Public Easements July 2009 Slide 5Richard Paine, Self

6. doc.: IEEE 802.11-09/0830r1 Submission Search and select an easement When user presents Easement Name (eg: texting or multimedia) as passcode, the traffic is passed through the public easement.

8. doc.: IEEE 802.11-09/0830r1 Submission July 2009 Slide 8Richard Paine, Self Easement Comparison to Existing Services Texting and low bandwidth are integral applications and services for ISPs. Existing examples: iTunes easements at Starbucks Amazon easements at all WISP locations Libre Texting: http://www.neda.com/PLPC/110015 Business Considerations Texting is low bandwidth, but high cost in cellular Secure texting and content-based easements needed in WLANs to have comparable services to cellular Location and content considerations for 802.11 growth and profitability 802.11 Considerations Need security and location protocol elements Integrate MAC easement elements like security, location, etc

9. doc.: IEEE 802.11-09/0830r1 Submission July 2009 Richard Paine, SelfSlide 9 Public Easement Information Texting and short multimedia applications are very small and needing 802.11 ubiquity –Inconsequential bandwidth –Secure easements availability in all WLANs –Location-based and needing texting content protection Multimedia (A/V) applications are becoming ubiquitous in WLAN –Music Purchasing –Multicasting/Broadcasting –Video conferencing –Real-time Streaming –3D gaming Content protection requirement is ubiquitous –Content provider’s content –User generated content Easement and content protection support is required from MAC and PHY in WLAN –Proximity control –Packet-level link protection

10. doc.: IEEE 802.11-09/0830r1 Submission Enticement to buy more access and bandwidth Access point manufacturers would want to move toward ubiquity – vehicle to expand market Move from personal to ubiquity – more access points Easement providers gain location and usage information Location-based applications can be created Public easement increases foot traffic - desireable place to be Business Case for Providing Public Easement July 2009 Slide 10Richard Paine, Self

12. doc.: IEEE 802.11-09/0830r1 Submission July 2009 Richard Paine, SelfSlide 12 Proximity Control Requirement Content may need to be constrained to a certain range or location (location provided by 11k and 11v). For example, within the black circle vs coverage (red circle).

13. doc.: IEEE 802.11-09/0830r1 Submission July 2009 Richard Paine, SelfSlide 13 Summary Public easements are a request for limited free access to WLANs Content protection is becoming a crucial issue for Texting/Audio/Visual applications for WLAN. Content protection requires support from MAC and PHY layers in WLAN. –Security controls –Proximity control –Packet level rights control Lack of such support in current WLAN solutions. Call for discussion.
