Abstract
IEEE 802 ECSG on White Space ADHOC USE CASE slide deck to capture TVWS USE CASE Sceneraios
Purpose
To provide input to the ECSG and others on possible use cases that will help clarify how the TVWS spectrum might be used and how these uses might possibly be addressed by IEEE 802 work.

Shellhammer Input
Broadband wireless internet access? Yes, with VOIP over the broadband, but may use the frequencies for other applications like sensors or in-home devices that do not require broadband wireless internet access.
Ranga Reddy Input
Ranga Reddy input - star/tree/mesh? Maybe?
Have we covered sufficiently the requirements?

7. Geo-location /Regulatory
100mW/50mW (sense only) Whitespace Use Case
In-building or out-of-building outside the protected contour (41dBmicroV/m on channel) on non-adjacent channels where many TV channels are being used
Suburban Neighborhoods
Farm
Wireless device access in a residence or farm or neighborhood
Areas of weak TV broadcast signals
Access Points – may or may not be for broadband Internet access
Unlicensed Voice Applications – ex: Femtocell-like
Point-to-Point Wireless
Physical Area

11. NOI Use Case Implications
Will represent a “high power use case” versus current 4W TVWS R&O & Errata
NOI work status is unknown and may not be actively “in progress”
Maybe geared toward very Rural low density deployments covering large areas
Will provide much larger coverage areas at low cost
May require both database, sensing together & also higher power CPE
May require adjustments/amendments to R&O’s “fixed wireless” rules

12. Discussion Inputs
Use case: broadband wireless Internet? Not necessarily
Whether to contribute star, tree, or mesh as a use case? Within a use case?
Health issues?
Security?
Keepaway zones/incumbent protection
Use of the 4W by cell towers/organizations/safety/emergency responders/etc
Economics of using competing/complimenting wireless technologies
Data base
Sensing
Cognitive radio applications/Interactive radio station (IP-based transport)

Topologies depend on the use cases

13. Use Case Conclusions THE TVWS USE CASES WILL..
..be part of a larger Wireless eco-system
..be driven by both Market demand & Policy requirement
..may be hard to predict the most common use cases before we “get there”
..will facilitate, and be facilitated by, innovation & policy goals
