  1. Presentation Summarizing Contribution onTV Whitespace Coexistence Matrix and Use Cases Date: 2009-05-17 Authors: Richard Paine, Self; Mark Cummings, EnVia; Alex Reznik, Interdigital Slide 1

  2. Propose modification to the co-existence matrix • Suggest an additional element of “network operation/ownership” to be considered as part of a use case • Provide detailed analysis of 2 use cases • Campus (i.e. college campus, suburban mall, etc.) • Large apartment building Abstract Richard Paine, Self; Mark Cummings, EnVia; Alex Reznik, Interdigital Slide 2

  3. Whitespace Coexistence Matrix Richard Paine, Self; Mark Cummings, EnVia; Alex Reznik, Interdigital Slide 3

  4. It would appear that in general different technologies cannot co-exist except through sufficient geographical separation • UWB is an exception • However, this depends on an underlying assumption of passive co-existence • In some cases, the notion of an active coexistence enabler is not unreasonable • For example if a single operator of a heterogeneous network is provided such a device • Our use-case study needs to address such possibilities • In particular, we should differentiate between co-existence between networks operated by different entities and co-existence of network operated by the same entity • We examine two scenarios which make illustrate this point Observations from the Matrix Richard Paine, Self; Mark Cummings, EnVia; Alex Reznik, Interdigital Slide 4

  5. The Campus Use Case • Key aspects of this Use Case • Presence of macro-coverage • Cellular providers • Fixed WWAN (Wimax) • Potentially high density of 100mW devices • WiFi networks (per store, department, etc.) • WiFi hot-spots • Femto-cells • 40 mW devices • Microphones • Presence of a single coordinating entity • Campus owner • Mall owner • This entity may • Own and sublease all or part of the network • Impose constraints and requirements on network operations by individual operators Richard Paine, Self; Mark Cummings, EnVia; Alex Reznik, Interdigital Slide 5

  6. The Apartment Building Use Case • Key aspects of this Use Case • Presence of macro-coverage • Cellular providers • Fixed WWAN (Wimax) • Potentially high density of 100mW devices • WiFi networks (per store, department, etc.) • WiFi hot-spots • Femto-cells • 40 mW devices • Microphones • Each apartment potentially an independent network • May use different broadband/cellular/femto-cell providers • No ability to coordinate WiFi usage (except maybe direct human goodwill) Richard Paine, Self; Mark Cummings, EnVia; Alex Reznik, Interdigital Slide 6

  7. Voice (4W or low power Whitespace frequencies) Femtocell (low power Whitespace frequencies Internet (4W or low power Whitespace frequencies) VOIP (4W or low power Whitespace frequencies) Cellular Provider Use of Whitespace • Two Different Cellular Providers • Different WS Channels Richard Paine, Self; Mark Cummings, EnVia; Alex Reznik, Interdigital

  8. Home (low power Whitespace frequencies) Enterprise (low power Whitespace frequencies) WiFi Hotspot (low power Whitespace frequencies) Internet Access (low power Whitespace frequencies) VOIP (low power Whitespace frequencies) WiFi Provider Use of Whitespace Richard Paine, Self; Mark Cummings, EnVia; Alex Reznik, Interdigital

  9. Voice (low power Whitespace frequencies) VOIP (low power Whitespace frequencies) Internet (low power Whitespace frequencies) Suburban (4W Database) Rural (4W Database) Fixed WWAN (WiMAX, 802.22)Provider Use of Whitespace Richard Paine, Self; Mark Cummings, EnVia; Alex Reznik, Interdigital

  10. WS TV Broadcast (4W Database) Non-802 Protocols (4W Database or low power Whitespace frequencies) Local TV Broadcast TV Broadcaster Richard Paine, Self; Mark Cummings, EnVia; Alex Reznik, Interdigital

  11. Voice (low power Whitespace frequencies) Non-802 Protocols (low power Whitespace frequencies) Microphone Provider Use of Whitespace Richard Paine, Self; Mark Cummings, EnVia; Alex Reznik, Interdigital

  12. Made comments to the matrix • Presented 2 use cases (see our text for more detail) • Propose that the notion of a “operating entity” is an important factor in considering a use case. Conclusions Richard Paine, Self; Mark Cummings, EnVia; Alex Reznik, Interdigital
