802 Whitespace Use Cases

2. 802 Whitespace Use Cases Richard Paine/Nanci Vogtli/Dan Lubar

3. Whitespace Use Case Review • Group decision to discuss use cases based on the regulatory constraints • 4W Use Case • 100mW Use Case • 40mW 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 • Fixed, Master, client • Identify all devices that might be involved.  • Contrast what is different between licensed bands and new frequency

4. 4W Whitespace Use Case - Fixed • Out-of-building in areas of weak TV broadcast signaling • Towns • Farms • Suburbs Client • Grain Elevator Enterprise • Slaughterhouse Enterprise • Waterpark Enterprise • Hunting Lodge • Fishing Lodge • Agriculture Enterprise • Military Equipment • Public Safety Equipment • Master • Database Access • Cell Towers Installable • Private Comm. Systems • Emergency Services • Water Towers • 20-30km Coverage • Suburban • Consolidated Access (MDU/MTU) • Military Operations • Public Safety Client • Light Residential/Suburban • Farming & Agricultural Client • Ranching • Mountainous

5. 100mW Whitespace Use Case • In-building or out-of-building in areas of weak TV broadcast signaling • 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 • LAN 100m • Residential • Neighborhood or farm star/tree/mesh? Client Client Master

6. 40mW Whitespace Use Case • In-building in relatively strong TV broadcast signaling • Areas of relatively strong TV broadcast signals with less bandwidth avbl • Access Points • Unlicensed Voice Applications – ex: Femtocell-like • Point-to-Point Wireless • Portability • Body Area Networks (BAN) – may not be broadband Internet access • Area • Indoor Networks • PAN • 10m Client Client Master

7. <40mW Whitespace Use Case • PAN • Body area network support • Areas of relatively strong TV broadcast signals with less bandwidth avbl • Body Area Networks (BAN) – may not be broadband Internet access • Sensing devices and microphones Client Client Master

8. NOI Use Case Implications • Should represent a “high power use case” than that of current TVWS R&O or its imminent R&O Errata • NOI work status is unknown and may not be “in progress” • Geared toward very Rural, very low density deployments • Purpose may be to provide larger coverage areas • May require database, sensing together & a higher power CPE • May require adjustments/amendments to R&O’s “fixed wireless” rules

9. 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 • Use of the 4W by cell towers/organizations/safety/emergency responders/etc • Economics of using competing wireless technologies (802.11?) • Data base • Sensing • Protective Contours (Keepout Frequencies) • Interactive radio station (IP-based transport) • 30 min presentation on big Whitespace group at next Whitespace meeting • Topologies depend on the use cases

10. Use Case Conclusions THE TVWS USE CASES WILL.. • Will be part of a larger Wireless eco-system • Be driven by both Markets & Policy demands & requirements • Be hard to predict before we “get there” • Will facilitate, and be facilitated by, innovation
