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.

802 Whitespace Use Cases

Richard Paine/Nanci Vogtli/Dan Lubar

Whitespace Use Case Review• Group decision to discuss use cases based on the regulatory constraints

• 4W 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

4W Whitespace Use Case - Fixed

• Grain Elevator Enterprise• Slaughterhouse Enterprise• Waterpark Enterprise• Hunting Lodge• Fishing Lodge• Agriculture Enterprise• Military Equipment• Public Safety Equipment• All Business Enterprises

• Light Residential/Suburban• Farming & Agricultural

• Ranching• Mountainous

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

• Outdoor use in areas of weak TV signals or un-used TV channels• Towns• Farms• Suburbs

100mW Whitespace Use Case• In-building or out-of-building in areas of weak TV signals or un-used TV channels

• 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

Client

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

<40mW Whitespace Use Case• Areas of relatively strong TV broadcast signals with less bandwidth avbl

• Body Area Networks (BAN) – may not be broadband Internet access• Protection Beacons and Microphones• In-home backhaul• Network Sensors/Control Devices• Smart Utility Networks• PANs

Service Rules by Different Countries• US rules (Part 15, Part 74, and Part 90)

• Canada rules

• EU rules

• Australia rules

• UK (OFCOM)

• Asia rules

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

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
