Wilmington, NC - March 26, 2012 Approved second data base
administrator Telcordia - April 19, 2012 Approved second device
Adaptrum authorized deployment in Nottaway, VA
4TV White SpaceWhat We Are Doing
- Accepting processing applications for equipment
certification - Continuing process to approve data base
administrators - Establishing wireless microphone registration
process - Waivers to register certain TV receive sites in
data base
5Benefits of TV White Space
- Prime spectrum
- Great propagation coverage
- High amounts in much of the USA
- Close to spectrum used by commercial wireless
services - - potential synergy - New IEEE 802.22 standard
- IEEE SA Emerging Technology of the Year Award
- Broadband wireless access over a large area up to
100 km - Up to 29 Mbps per TV channel
- Can increase data rate through use of multiple
channels - Wi-Fi TV White Space is not an either-or
proposition - Each may suit particular needs
- Wi-Fi has greater bandwidth but usage density is
increasing - When combined consumers users could see
significant benefits -
6Potential Applications
Provides a new opportunity for innovation and
delivery of service, with potential for both
research and commercial applications Spectrum is
open to everyone and is available now
- M2M
- Smart Grid
- Health Care
- Education
- Data traffic off-load
- Broadband (generally)
- Rural broadband
- Video Monitoring, surveillance, distribution
- State Local Governments
Potential uses limited only by the imagination
7TV Broadcast Incentive Auctions
- Middle Class Tax Relief and Job Creation Act of
2012 (Spectrum Act) provides for TV incentive
auction - Incentive auction would share auction proceeds
with the current occupant to motivate voluntary
relocation of incumbents - Broadcaster participation in incentive auction is
voluntary - In exchange for a share of auction proceeds a
broadcaster could - Contribute one or more 6 MHz channels
- Choose to move from U to V
- Share a channel with another broadcaster
- Or choose not to participate
- FCC actions
- Formed Incentive Auctions Task force Co-chairs
Ruth Milkman and Gary Epstein - Order on channel sharing adopted at April 27
agenda meeting - Notice of proposed rule making planned by this
fall
8The FCC Would Need to Realign the Spectrum After
the Auction
Adjacent Channel Interference
- FCC would realign the spectrum into blocks to
maximize efficiency and value - Without realignment, interference between
television and wireless operations would increase - The FCC would work with industry to minimize any
interference or coverage impacts of realignment,
as we did for the DTV transition - Stations keep current channel numbers
- Moves to a lower band would be voluntary based
on broadcaster reserve price - Spectrum Act provides funding to relocate
operations in TV channel 37 if necessary

9Impact on TV White Space
- FCC will need to create band plan
- Spectrum Act
- FCC may implement band plans with guard bands
- Guard bands shall be no larger than is
technically reasonable to prevent harmful
interference between licensed services outside
the guard bands - May permit use of guard bands for unlicensed
- Unlicensed use shall rely on a data base or
subsequent methodology as determined by the
Commission - Benefit - - contiguous band available everywhere
- There will be white space size of guard bands
remaining TVWS TBD through rule making
10Sharing with Radars at 5 GHzIx Issues
Spectrum Expansion
- Sharing based on Dynamic Frequency Selection
(DFS) - Devices listen and perform processing to
detect radars - Spectrum Act requires study of expanded
unlicensed _at_ 5 GHz - Related to IEEE 802.11ac standard under
development
Device detects radar and moves to an unoccupied
channel

Frequency (MHz)
11NTIA Report on 1755 1850 MHz
- NTIA recently released report on potential for
reallocation of federal spectrum at 1755 1850
MHz for wireless broadband - Numerous challenges - - cost, complexity, time
- Strong support for increased sharing
- T-Mobile recently filed for an experimental
license on behalf of CTIA to perform sharing
tests - NTIA to convene work group under Commerce
Spectrum Management Advisory Committee - FCC will participate in work group
- Federal Incumbent Systems
- Fixed Point-to Point Microwave
- Military Tactical Radio relay
- Air Combat Training System
- Precision Guided Munitions
- Tracking, Telemetry Commanding
- Aeronautical Mobile Telemetry
- Video Surveillance
- Unmanned Aerial Systems
- Other Systems
12Small Cells at 3550 3650 MHz
- Small cells can reduce traffic on wide-area
networks - provide coverage and capacity where
needed - Example Wi-Fi offload
- Today, re-connect at each AP
- Soon, seamless connectivity
- FCC Technological Advisory Council recommended
federal fast-track band 3550 3650 MHz for small
cells - This band had little interest for wide-area
networks due to high frequency exclusion zones
- Several approaches are possible for small cells
and other uses in this spectrum - Proceeding later this year
13MSS S-Band Proposal
- Notice of Proposed Rule Making - March 2012
- Proposes to relax rules to facilitate increased
terrestrial use of S-band MSS spectrum at 2000
2020 MHz (Earth-to-space) and 2180 2200 MHz
(space-to-Earth) - Notice of Inquiry invites comment on potential
band realignment to create opportunities to
expand PCS - Comments due this Thursday
- Figure 1 Existing 2 GHz Band Plan
- Figure 2 Proposed AWS-4 Band Plan
14Receiver Performance
- Increasing focus on receiver performance as
limiter to spectrum access efficiency - FCC conducted workshop on March 12 13, 2012
- Various policy approaches suggested
- FCC Technological Advisory Council (TAC) is
studying the issue looking towards making FCC
recommendations
15Medical Body Area Networks (MBANS)
- MBANS are very short-range networks consisting of
multiple body-worn sensors (eg, on a patients
chest, back, arms, etc.) and a nearby hub
station - Sensors take readings of key patient-specific
information (eg, temperature, pulse, blood
glucose level, etc.) - Antennas embedded in sensors make it possible to
wirelessly transmit data to body-worn or closely
located hub devices - Hub devices may process data locally and/or
transmit it wirelessly for centralized
processing, display, and storage - MBANS can reduce infection risk, increase
patient mobility improve caregiver
effectiveness - FCC issued Notice of Proposed Rule Making for
MBANS to share 2360 2400 MHz w aeronautical
telemetry - Industry has submitted jointly agreed proposed
rules - FCC plans to consider at May 24, 2012 agenda
meeting
16Experimental Licensing Notice of Proposed Rule
Making (ET Docket No. 10-236)
- Notice of Proposed Rule Making (NPRM) seeks to
promote research and development of new radio
technologies, devices, and applications. - Proposed to create a new type of Program License,
which would give qualified entities broad
authority to conduct a program of research
without the need for approval of each experiment.
- Â
- Proposed three types of Program Licenses
- Research license would allow universities,
laboratories, and other qualified research
institutions to conduct experiments over a wide
variety of frequencies and other operating
parameters, without the need for individual
authorization or reauthorization for each
individual experiment. - Geographic innovation zones generally
relatively remote locations - where researchers
could conduct a wide range of experiments under
certain general conditions. - Medical institutions to innovate and develop new
devices that can save lives, have a significant
impact on reducing medical costs, and provide new
treatment options for our wounded service men and
women. - Â
- Proposed ways to streamline and clarify the
existing rules such as expanding opportunities
for researchers and manufacturers to conduct
market trials

17FCC Notice of Inquiry on Dynamic Spectrum Access
(ET Docket 10-237)
- Notice of Inquiry (NOI) considers how dynamic
access radios and techniques can provide a more
intensive and efficient use of spectrum - Seeks comment on the current state of the art and
how FCC can promote these technologies - -
test-beds or modifying its spectrum management
practices and policies - Covers both licensed services and unlicensed
devices - What spectrum bands would be most suitable?
- Asks whether TV White Space model might be used
for other bands - Asks whether and how to incorporate spectrum
sensing for other bands - Asks whether FCC provisions for secondary market
arrangements could be enhanced to increase use by
dynamic access radios - Asks how to improve FCC Spectrum Dashboard for
DSA
