Reconfigurable Radios The Problem

• From an ITS Reconfigurable Radios perspective
  -Wireless standards change on average every 18
  months, while average automobile design takes 3
  years, and cars last an average of 10 years
• Without Radio Reconfiguration capability,
  different RF hardware has to be designed and
  provisioned per region, per function
• Particularly severe constraint in vehicles
  analog digital audio, GPS tracking,
  WWAN/Internet, WWAN/Emergency Information
  Delivery, tolls/EZPass, key access, radar, BT,
  WLAN, etc.
• Updates (critical or not) in any of the wireless
  technologies means cost
• Multimode Mobiles need to support different
  3G/4G/WLAN/BT standards and 5 frequency bands
  today, and more coming
• Cost, power implications
• Will get worse with future multipurpose broadband
  devices for converged WWAN/WLAN/PAN/BAN..

Reconfigurable Radios The Goal

• Source Presentation on SDR by Dr John Chapin of
  VANU Inc. at the Fully Networked Car Conference,
  Geneva, 5-7 March, 2008

Reconfigurable Radios - Rationale

• Reconfigurable Radios (RRs) are expected to
  reduce device BoM cost and be upgradable in the
  field to support future communications standards
  and applicable spectral bands
• RR capable hardware is software loaded, i.e.
  customized, for destination at appropriate point
  in supply chain
• Some vendors have integrated RRs in deployed
  infrastructure and subscriber units, but admit
  limited or no frequency agility (flexibility)
• Key question does this need standardization?

5
Key Interfaces ITS/SDR Forum

• The ITS industry and the SDR Forum are asking for
  a new Digital IF standard
• Implies common baseband processor for multiple
  radios
• Existing specifications - OBSAI, CPRI, DigRF -
  found not appropriate for automotive requirements
• RF configuration/control is the challenge
• The SDR Forum has significant activity in this
  area

Frequency band flexibility is still a major
limitation without Digital RF implementation
6
Regulatory Aspects

• United States
• FCC Rules on Free and Open Source Software (FOSS)
  and Software-Defined Radio, July 6, 2007
• for certification of devices whose radio
  frequency and power characteristics can be
  modified by software
• new process allows vendors to update critical
  software on the devices without re-certifying the
  devices with the FCC
• supports open standards in principle to
  strengthen the security and robustness of
  wireless devices
• FCCs challenge to the industry related to SDR/RR
• to prevent unauthorized changes to the software
  on the device that might alter its radio
  frequency and power parameters in a way that
  takes it out of compliance with the regulations
  known as FCC Part 15 regulations

Recent Activity - ETSI

• ETSI created a Technical Committee for
  Reconfigurable Radio Systems (RRS) in January
  2008 to study the feasibility of standardization
  related to Software Defined Radio (SDR) and
  Cognitive Radio
• Feasibility report expected by Jan 2010
• Committee focus on systems aspects, equipment
  architecture, functional architecture
• Clear focus on Public Safety application,
  recognizing requirement for SDR and CR from
  Defence and Public Safety segments
• Liaisons with bodies in the area, as IEEE, SDR
  Forum and others working in the field of SDR and
  CR

8
Recent Activity - ITU

• Report ITU-R M.2117 Software defined radio in
  the land mobile, amateur and amateur satellite
  services approved by ITU WP 8A addresses
• Characteristics of software-defined radios
• Software download types and security issues
• Deployment considerations
• Potential regulatory implications
• SDR application to specific mobile systems
• Technology aspects related to IMT-2000
• Includes input from WP 8B (radars), WP 8D (mobile
  satellite systems), and WP 8F (IMT-2000 and
  systems beyond IMT-2000)
• Report M.2064 (2005) is also a reference for this
  area
• Need information on location and characteristics
  of other RATs through access to a database
  supporting access and connectivity or by using a
  Cognitive supporting Pilot Channel (CPC)
• Ch6 - AI 1.19 considering regulatory measures in
  order to enable the introduction of
  software-defined radio and cognitive radio systems

Recent Activity - ISAAC

• Reference ISAAC Contribution GSC-13 PLEN 05 for
  Emergency Communications RES
• software-defined radio (SDR) and cognitive
  functions1 could facilitate interoperability
  among public-safety agencies by adapting to
  changing communications protocols and frequency
  bands
• 1 With regard to the 2011 World
  Radiocommunication Conference (WRC-11), agenda
  item 1.19 addresses the consideration of
  regulatory measures and their relevance, in order
  to enable the introduction of software-defined
  radio and cognitive radio systems, based on the
  results of ITU-R studies.

Recent Activity - IEEE

• Reference Contribution GSC13-PLEN-62
• P802.22 series for cognitive wireless RAN medium
  access control (MAC) and physical layer (PHY)
  specifications policies and procedures for
  operation in the TV bands
• P1900 series under SCC 41, Dynamic Spectrum
  Access Networks, including terminology, analysis
  of interference and coexistence, spectrum access,
  architectural building blocks for distributed
  device decision making

11
Recent Activity - TIA

• Relative to Reconfigurable Radios, TIA TR-8
  focuses on Public Safety
• Users in TR-8 have expressed a desire to look at
  SDR aspects, and a subcommittee was created years
  ago, TR-8.7, but has been relatively inactive
• Multiple bands are in use by systems for first
  responders
• TR-8 Chair reported renewed interest in Software
  Defined Radio work
• leadership for subcommittee TR-8-7 being sought

12
Challenges

• Digital IF interface specification (ITS)
• Support for multiple radios, on plug and play
  basis, nearer term
• Support for growing number of wireless standards
• C2K, GSM/GPRS/EDGE, EV-DOrA, HSPA, LTE, WiMAX,
  802.11x, 802.15.x, 802.16d, 802.20, etc as
  applicable)
• Also BT2.x/3.x, Zigbee, UWB, NFC, new CAI for BAN
  profiles, etc
• Tunable filters and amplifiers, broadband
  antennas
• Digital RF for global frequency flexibility, (no
  need for agility?)
• 450MHz/700MHz/850MHz/900MHz/GPS1.575GHz/Galileo1.2
  78GHz/GLONASS/1.7GHz/1.8GHz/1.9GHz/AWS/2.3GHz/2.5G
  Hz/3.3GHz/3.5GHz/4.9GHz/5.8GHz
• low power, low footprint, in CMOS, hence low
  cost, RFICs
• an implementation challenge, to achieve economies
  of scale
• FCC security requirement to prevent hacking to
  alter operating band

Proposed Resolution

RESOLUTION GSC-13/XX (GRSC) Software Defined Radios and Cognitive Radio Systems (Revised Draft)

• The 13th Global Standards Collaboration meeting
  (Boston, USA, 2008)
• Recognizing
• that Software Defined Radios (SDRs) may offer
  design and operational versatility and
  flexibility in mobile radio systems
• that for in-vehicle use, SDRs may help in
  reducing the mismatch between the lifecycles of
  vehicles and communications technology
• that SDRs have been addressed in a variety of
  organizations often by people interested in
  different aspects and for different purposes
• that the terms used in association with SDRs and
  with Cognitive Radio Systems currently vary
  significantly
• that some of the features that many would
  currently associate with SDRs do not, in fact,
  require SDR technology to be implemented or
  achieved (e.g., some kind of flexibility may be
  obtained by multimode equipment)
• that the use of SDR or Cognitive Radio Systems
  may have implications on the radio parameters,
  security, and/or reliability of operation
• that it would be useful if SDOs and regulatory
  bodies adopted a common set of terms covering the
  various aspects relating to SDRs (e.g., focusing
  on various layers, physical, logical, etc.) and
• the importance of cognitive radio technology and
  the need for a common understanding of what is a
  cognitive radio system.
• Considering
• Report ITU-R M.2117 Software defined radio in
  the land mobile, amateur and amateur satellite
  services
• Question ITU-R 230-1/8 Software defined
  radios and
• Question ITU-R 241/8 Cognitive radio systems in
  the mobile service.
• WRC-11 Agenda Item 1.19 to consider regulatory
  measures and their relevance, in order to enable
  the introduction of software-defined radio and
  cognitive radio systems
• Resolves
• to encourage Participating Standards
  Organizations (PSOs), and to invite other
  standards bodies and regulatory bodies, to
  cooperate in order to adopt common terminology
  definitions covering the various aspects relating
  to SDRs and
• to encourage PSOs, and to invite other standards
  bodies and regulatory bodies, to cooperate in
  order to adopt a common terminology definition
  and common approaches to cognitive radio
  technology.
