Highlights of Current Activities –
Summary
 Most activity about reconfigurable radio systems (RRS),
including cognitive radio (CR) and software defined radio (SDR),
has been conducted in ETSI, IEEE, and ITU-R. Other
contributions come from groups including OMG and especially
the Wireless Innovation Forum (formerly SDR Forum)
 Working definitions of SDR and CR were adopted in 2009
• ITU-R WP1B is the responsible group for WRC-11 AI 1.19
• ITU-R WP5A is developing a report on a definition for CRS and
input for WP1B
• ITU-R WP5D is giving input to WP5A on CR related to IMT/3G
 Market and regulatory issues, including potential benefits and
potential complications, are also being studied
• In early 2010, the U.S. FCC granted several experimental licenses for work
in TV white space; FCC movement in this area is still slow
2
Highlights of Current Activities – IEEE
 IEEE 802.22 (standard for WRAN using TV white spaces) is
still in the standard drafting stage
 IEEE 802.16h (improved coexistence of 802.16-based
networks in unlicensed bands) reached sponsor ballot stage
 The IEEE 802.19 technical advisory group is evaluating
coexistence between IEEE 802.11y and IEEE 802.16h
 March 8-11, 2010: IEEE SCC41 Meeting (co-located with the
Wireless Innovation Forum 65th General Meeting)
• Ad hoc committee on White Space Radio (1900.7) was created
within IEEE SCC41
 Purpose: to consider standard defining MAC and PHY layers for
white space communication system

Highlights of Current Activities – ITU-R
 In June 2010, ITU-R WP1B finalized the draft CPM
text for WRC-11 Agenda Item 1.19 (introduction of
software-defined radio and cognitive radio
systems)
 During 2009, ITU-R WP5A received many
contributions from equipment makers, telecoms
carriers, and governments to its draft report on
“Cognitive radio systems in the land mobile
service”

Highlights of Current Activities – OMG
 Object Management Group (OMG) Software-Based Communication
(SBC) Domain Task Force (DTF) develops and promotes
specifications for SDR devices, through activities including
• Promotion of UML and model-driven technology
• Development of specifications to improve interoperability of softwaredefined components
• Promotion of software radio specifications
 SBC DTF and the Wireless Innovation Forum – supported by several
companies – are working on a commercial standard based on the SCA
 OMG and the Wireless Innovation Forum released a joint smart
antenna specification in May 2009 – their first joint specification

Highlights of Current Activities –
Wireless Innovation Forum (1/2)
 Name changed from SDR Forum in December 2009
• Website: www.wirelessinnovation.org
 116 organizational members, including
• Huawei (joined in 2009)
• ZTE (joined in 2010)
 First TV White Spaces Summit was held June 15, 2010, in
Washington, DC
•
•
•
•
Discussed commercialization of TVWS
Reviewed the progress of proposed standards
Examined technology/regulatory/deployment requirements
Keynote by Commissioner Meredith Baker of the U.S. FCC
encouraging movement in this area

Highlights of Current Activities –
Wireless Innovation Forum (2/2)
 66th General Meeting was held June 21-23, 2010, in Mainz, Germany
•
•
•
CRWG met jointly with PS-SIG to collaborate on Information Process Architectures
CRWG finalized and balloted “Quantifying the Benefits of Cognitive Radio”
CRWG work continues on two projects


•
•
•
“Cognitive Radio Database (CRDB) – a Radio Environment Map (REM) anticipating future CR needs”
“Information Process Architecture”
MLM-WG continued work on the report “Modeling Languages for Mobility”
T&M WG continued work on “Test Guidelines and Requirements for Television
Band Devices (TVBDs) Designed to Operate on Available Channels in the
Broadcast Television Frequency Bands”
SAWG worked on “Smart Antenna Specification: PIM and PSM for Smart Antenna”
 Second annual European Reconfigurable Radio Technologies Workshop
was held June 23-25, 2010 in Mainz, Germany
 67th General Meeting will be held Sept. 17-19, 2010, in Schaumburg,
Illinois, U.S.A. (hosted by Motorola)
•
Second TV White Space Summit to be held with the 67th General Meeting

Challenges (1/2)
 The market is moving very fast, complicating standardization
• Debate continues over the role of standards in RRS
 What needs to be standardized? Will setting standards so early in RRS
development hurt innovation?
• Several technologies are competing for de facto standard status
 Regulatory bodies need to make sure that devices will meet current and
future requirements
• Most interest has been on the business and technology sides, but
mature policy is also necessary for RRS to succeed
• A conformity assessment apparatus is necessary
 Regulators also need principles for considering questions unique to RRS
• Example: whether to allow software updates without requiring a
device to be recertified
8
Challenges (2/2)
 Existing services (especially public safety) need protection from
interference that might result from SDR and CRS
• Some standards and/or regulatory entities might want to exclude
SDR/CRS from some bands
 Some countries (e.g., the U.S., Canada) have not recommended
regulatory changes or changes to ITU rules before RRS can be
implemented, but other countries might
 On the technology side, standards are needed for components that
make CR networks secure from various kinds of DoS attacks, a
generalized CR-MAC, and cross-layer design
 Despite all of the efforts, the real need for vehicle manufacturers is the
ability to build vehicles with radios that can be updated for new
protocols over the life of the vehicle

Summary
 ETSI has initiated major Reconfigurable Radio
Systems activities
 CCSA has projects on Cognitive Radio Systems
 Progress on RRS continues to move slowly
around the world
