Abstract
The intent of the FCC in the recent Second Report and Order setting out the rules for unlicensed operation in the TV bands can best be understood by looking at some earlier related rulings and inquiries.

Introduction
• The FCC problem– More spectrum needed for wireless future– Sharing with licensed users is a necessary evil– No increase in enforcement resources – Do not want to repeat (registration) errors of the past
• The solution, in a number of steps– Announce the spectrum opportunity– Engage industry– Test the self-policing mechanisms– Set the rules
• Historical perspective required to understand the intent of the new Part 15.700 rules

First Steps
• Policy Statement FCC 00-401 & NPRM FCC 00-402 (November 2000)– Recognize the need to share spectrum to support the burgeoning wireless
applications
– Examine how to remove regulatory barriers for efficient spectrum sharing
– Enable development of methods for opening licensed bands for sharing
• NOI FCC 02-380 (December 2002) – Requesting comments on opening the unused TV spectrum for unlicensed
use
NPRM = Notice of Proposed Rulemaking
NOI = Notice of Inquiry

Opening the TV Bands
• NPRM FCC 04-113 (May 2004)– Enabling unlicensed use of unused TV channels– Keepout zones, beacons and sensing requirements– Primarily rural applications
• NPRM FCC 04-100 (April 2004) & R&O FCC 05-56 (March 2005)– Open 3650 to 3700MHz Government Transfer Band for cognitive access– Sharing of 50MHz; 25MHz of it also open to non-cognitive access, such
as WiMAX– Must include self regulating mechanism

IEEE 802.22
• Task Group formed in 802.18, the RR-TAG– Chair stepped down to lead the Study Group
– New WG formed in September of 2004
• Based on NPRM 04-113, focused on rural access applications– Similar to WiMAX (802.16) with sensing mechanisms
– Trying to adapt to meet Part 15.700 rules• Database rules with sensing; study the value of beacons
• Require synchronized (to GPS clock) quiet periods for all TV Band Devices (TVBDs)
• Now scrambling to add personal/portable device support
• Still no 802.22 approved draft
RR-TAG = Radio Regulatory Technical Advisory Group

IEEE 802.11y
• CBP SG started March 2005; TG in March 2006– CCA changes to allow operator adjustment– Station enablement mechanism on timed hear and decode beacon
• Fixed, registered stations transmit beacon• STA not receiving must stop transmitting after preset interval
– Registered STAs in database for interference mitigation without FCC intervention
• P802.11y completed and approved November 2008• Manufacturers not yet making a major commitment
– Small amount of spectrum available (50MHz)– Approval process, at FCC labs is daunting and slow
CBP = Contention-based Protocol
CCA = Clear Chanel Assessment

Submission
The TVWS Rules: Part 15.700
• Second R&O 08-260 released (November 2008)– 17 petitions for reconsideration– Comment period ends May 8th– 10-day reply comment period
• A number of conflicting opinions must be resolved– Wireless microphone interference; both legal and illegal mics– 802.22-required silent period a non-starter for personal portable or other
indoor devices– Society of Broadcast Engineers, quoting from the Communications Act of
1934 says FCC can’t share the band – National Association of Broadcasters suing in Federal Court to stop all
TVWS action• Final result will probably await the seating of the new FCC
chairman (expected in July)
R&O = Report and Order
