VII Program and DSRC/WAVE

• U.S. DOT continues strong support for the vehicle
  infrastructure integration (VII) effort
• Strong (exclusive) communications emphasis on
  DSRC/WAVE at 5.9GHz (IEEE 802.11p)
• Testing to be extended in the VII program
• Continuing efforts toward
• Intersection collision avoidance
• Cooperative crash avoidance
• Application focus now in VII Consortium (U.S.
  DOT, state DOTs, and several vehicle
  manufacturers)
• VII Road Show beginning shortly live
  demonstration of VII technologies in multiple
  cities across the U.S.

Safety Message Communications in Low Coverage
Areas

• DSRC deployment leaves coverage gaps (not just in
  U.S.)
• Especially in rural areas where disproportionate
  number of crashes occur
• Need a wide-area vehicle data communications
  technology to fill gaps
• 700 MHz one possibility
• Safety messages to/from vehicles could be
  overlaid on public safety usage, especially in
  rural areas where this usage is low

5
700 MHz in the U.S.

• Spectrum becomes available with transition to
  digital TV
• 24 MHz allocated to public safety / emergency
  response
• 12 MHz wide band, 12 MHz narrow band
• FCC issued request for comments (March 2006) on
  proposals from Lucent, Motorola, and the National
  Public Safety Telecommunications Council (NPSTC)
  for the reconfiguration of the wideband portion
  for public safety
• More on this shortly, under Legislative/Regulatory
  Update
• ITS America is considering to comment, not to
  take sides but to make sure the vehicle safety
  communications issue is visible

6
U.S. Legislative/ Regulatory Update

• Communications Assistance for Law Enforcement Act
  (CALEA)
• FCC Second Report and Order and Memorandum
  Opinion and Order (FCC 06-56) see
  gsc11_grsc4_26a1
• Adopted May 3, 2006, ET Docket No. 04-295
  RM-10865
• Requires all carriers providing facilities-based
  broadband Internet access and interconnected VoIP
  services to comply with CALEA by May 14, 2007
• The FCC may take separate enforcement action
  against carriers that fail to comply
• Carriers are generally responsible for CALEA
  development and implementation costs for
  post-January 1, 1995 equipment and facilities
• Concludes it would be premature for the FCC to
  intervene in the standards development process
• Memorandum Opinion and Order
• Denies request to re-set the CALEA compliance
  deadline
• Concludes that the public interest is best served
  by the May 14, 2007 compliance date,
• Impact
• Extends the reach of CALEA to new services and
  technologies. What are the implications for next
  generation in-vehicle technologies?

7
U.S. Legislative/Regulatory Update (contd)

• 700 MHZ - 8th Notice of Proposed Rulemaking (FCC
  06-34)
• The Development of Operational, Technical and
  Spectrum Requirements for Meeting Federal, State
  and Local Public Safety Communications
  Requirements Through the Year 2010
• Adopted 2006-3-17, Released 2006-3-21, Comments
  Due 2006-6-6
• Seeks comment on
• Whether to modify the current 700 MHz band plan
  to accommodate public safety broadband operations
• Whether there is a continuing need for wideband
  data interoperability
• 3 Proposals - NPSTC, Motorola, and Lucent
• Recommends re-channelizing the wideband and
  reserve portions of the band nearly 12 MHz to
  accommodate broadband operations. 
• Interoperability. What provisions should be made
  for interoperability if the FCC creates broadband
  channels? What is the purpose of maintaining
  wideband interoperability channels in a broadband
  environment? Whether to adopt an
  interoperability standard and require all
  wideband/broadband radios to support such a
  standard?
• Narrowband.  FCCs tentative conclusion is not to
  alter the narrowband portions of the 700 MHz band.

8
U.S. Legislative/Regulatory Update (contd)

• 700 MHz (contd)
• Public Safety Applications
• How broadband applications for public safety
  could promote interoperability and whether to
  adopt interoperability standards for wideband and
  broadband channels.
• Channel Size and Spectrum Efficiency
• Whether high data rate broadband applications are
  a spectrally efficient use of the 700 MHz band or
  are better suited to the 4.9 GHz public safety
  band.
• Interference
• Methods of interference protection necessary to
  protect both adjacent narrowband operations and
  in-band broadband/wideband operations.
• Impact
• Spectrum could potentially also be used to fill
  gaps for vehicle safety communications where
  DSRC/WAVE services cannot reach, particularly
  rural areas.

9
U.S. Legislative/Regulatory Update (contd)

• Universal Service Fund (USF) Several Ongoing
  FCC Proceedings
• FCC is reconsidering how it collects the
  universal service fund because the current method
  is outdated and does not reflect todays market 
• Unclear if USF will expand to VoIP systems or
  voice-enabled instant messaging that do not rely
  on telephone numbers. 
• FCC Chair supports a "numbers-based approach,"
  which levies taxes on all phone numbers,
  regardless of calling technology used
• OnStar, ATX, and Mercedes filings oppose
  proposal, saying it is
• Inequitable and discriminatory Wide disparity
  exists between users and each cannot be assessed
  the same fee. Telematics does not compete with or
  substitute for regular voice services.
• A cost burden  A per phone-number is unfair
  because of low utilization of telecommunications.
  Average usage is less than 10 minutes per
  month.  Prepaid users pay no monthly charges.
• Not in the Public Interest Discourages use of
  life-saving telematics technology and hinders
  public service.
• Options FCC should exempt telematics, use
  current assessment model or percentage of
  telecommunications revenues based on an
  equivalency ratio adjustment to the monthly per
  phone number rate.
• Unaddressed issue is machine to-machine
  communications.

10
eCall and ACN

• In the U.S., the FCC has directed that all mobile
  phones must be able to provide their location for
  an emergency call (E-911)
• Technology up to phone vendor and carrier
• Could include a GPS chipset in phone ()
• Could try to triangulate phones signal (not very
  accurate)
• Deployment progress very slow, especially since
  this represents cost without revenue to phone
  vendors and carriers deadlines keep slipping
• In vehicles, sensible approach is to have the
  vehicle deliver its location to any onboard phone
  dialing 9-1-1 (1-1-2), most notably if the call
  is triggered by the vehicles detection of a
  crash
• Vehicle-delivered location helps to sync up eCall
  with ACN message
• Need Bluetooth profile for vehicle to deliver
  location and trigger call
• Need Bluetooth profile for phone to request
  location from vehicle for non-triggered eCalls
• In any case, standard format/rules needed for
  encoding location in message from phone to PSAP
• Need a crash message approach that does not
  depend on driver paying a monthly subscription
  charge

11
New Secretariat for ISO/TC-204

• ITS America is retiring as ANSIs designee for
  ISO TC-204 secretariat
• TIA is taking on this responsibility as of June
  2006
• TIA will also serve as Administrator of the U.S.
  Technical Advisory Group (TAG) to TC-204
• TIA has been WG16, Working Advisory Group (WAG)
  Administrator for over a decade and SDO involving
  air interfaces applicable to ITS
  messaging/notification and as a mobile Broadband
  communication media

12
Vehicle Communications Workshop and Exhibition

• In conjunction with the 77th International Geneva
  Motor Show 8-18 March 2007
• Follow-on to very successful workshop last year
  in same venue
• The Fully Networked Car II Workshop March 7-9,
  2007
• (sponsors include ITU, ISO, IEC)
• Exhibition March 8-18, 2007
• Urge all PSOs to notify their members and
  encourage their participation in the Geneva event
• ITS communications is emerging as part of overall
  interconnectivity paradigm shift involving the
  home/enterprise, mobile/nomadic devices, and
  transport vehicles like automobiles

13
Nomadic Devices

• Hot topic How vehicles will interface with
  nomadic devices
• Vehicle manufacturers are starting to think about
  building such interfaces (e.g., a docking
  station)
• Connector will probably become a consumer
  disposable
• Hot topic Standard for workload management
• i.e., get device to go dormant if driver workload
  exceeds a device-dependent threshold
• Standard Delivery of codes by vehicle to device
  characterizing current driver workload
• ITU APSC TELEMOV would be a good home for this
  activity

14
Location for Vehicle Safety

• Positioning dangerous conditions must be precise
  for roadways
• Hole in road 26 cm from right edge
• Crash vehicle position must be precise for
  emergency vehicles
• Upper level or lower level of roadway
• Main road of slip road

15
Privacy and Lawful Intercept

• An area of hot debate at present
• Privacy is a top requirement, but ...
• ITS communications will be subject to lawful
  intercept (wireless wire tapping) with court
  order
• CALEA (in the U.S.) and case law make clear that
  systems must be designed to make this reasonably
  easy
• Possible that records will have to be retained
  for court-authorized post hoc acquisition and
  analysis by law enforcement agencies
• Message authentication and hacking prevention
  will require some identifying information to
  travel with messages
• Can drivers be allowed to opt out in the name
  of privacy if this means they are withholding
  safety-critical data?

16
Software Reconfigurable Radios

• Separate report in more detail
• SRRs are software-based radios that can download
  and install updates to their own software, and
  which include updatable software-controlled
  antenna filters
• Essential for vehicle safety, considering
  mismatch in lifecycles between vehicles and
  communications technology
• GSC resolution needed to get this work rapidly
  under way approaching critical path
• Relevant standards venues include
• IEEE 802.22 for TV white space including the use
  of SDR
• IEEE P1900 series on spectrum management for
  policy-driven radios
