US FCC Regulatory Use Case Matrix CoChannel Adjacent Channel 4W Fixed X 4W Fixed to 100mW Portable 100mW Personal Portable 40mW Sense Only <40mW (Adjacent Channel) Everything outside the TV protected contour (41dBmicroV/m on channel)

Whitespace Use Case Review Group decision to discuss use cases based on the regulatory constraints 4W Use Case 4W to 100mW Use Case 100mW Use Case 40mW Use Case <40mW Use Case International Use Case Future looking NOI Use case 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? Categorize by power Terms: Fixed, Master, client Identify all devices that might be involved.  Contrast what is different between licensed bands and new frequency

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 40cm point-to-point 11

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) 30 min presentation on big Whitespace group at next Whitespace meeting Topologies depend on the use cases

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
