GSC9/GRSC_024a SOURCE: TIA TITLE: ITS Communications Update AGENDA ITEM: GRSC-2, Agenda Item 5.7 CONTACT: T. Russell Shields, Ygomi LLC, Email: [email protected] Tel: +1.847.577.9800, Fax: +1.408.873.2513 ITS Communications Update GSC-9, Seoul 1 Items for Discussion • FCC Notice on “Cognitive Radio” • Status of CALM M5 (WAVE at 5.9 GHz) • Vehicle safety communications TIA – Shields – ITS GSC-9, Seoul 2 Software-based Radios and Software-controlled Antenna Filters • ITS community has clear interest in this area – Can help create in-vehicle communications devices that will function for the service life of the vehicle – Important for Automatic Crash Notification • But ITS community not well informed on the subject • In late 2003, U.S. FCC issued a Notice of Proposed Rule Making (NPRM) seeking comments on “Cognitive Radios” TIA – Shields – ITS GSC-9, Seoul 3 FCC NPRM Seeks Comment On... • How to remove regulatory impediments to development and deployment of smart radio technologies • How to let unlicensed devices use higher transmission power in rural and under-served areas. – Would potentially reduce network infrastructure costs • How smart radios could facilitate public safety interoperability – Potential to serve as a communications bridge between two different radio services • Specific applications for smart radios, such as mesh networks and real-time frequency coordination • Ways the FCC can better accomplish cognitive radios and smart radio systems • See http://hraunfoss.fcc.gov/edocs_public/attachmatch/FCC-03-322A1.pdf TIA – Shields – ITS GSC-9, Seoul 4 DSRC at 5.9 GHz “WAVE” • Dedicated Short-Range Communications (DSRC) at 5.9 GHz now called WAVE (Wireless Access in Vehicular Environments) • Business case for building the 5.9 GHz beacons will be tested by a U.S. DOT project called VII (Vehicle Infrastructure Integration) • Possible applications for public authorities include – – – – – – Traffic Buses Heavy vehicles Police / fire / ambulance Vehicle safety Emergency response / evacuations. TIA – Shields – ITS GSC-9, Seoul 5 High Level of Activity • IEEE 1609 – – – – 1609.1: Resource Manager 1609.2: Application Services 1609.3: IP Network Services 1609.4: MAC Extension Services • IEEE 802.11 • ISO TC204 WG16 (ISO 21210 – CALM M5) – One of multiple technologies for CALM (Continuous Air interface for Long and Medium distance) – Also includes 2.5/3G cellular, 802.11a/g, infrared, millimeter (62-63 GHz) TIA – Shields – ITS GSC-9, Seoul 6 Vehicle Safety Data Communications • Data communications for vehicle safety requires very high reliability – In the advanced countries, new vehicles travel an average of more than 100 million kilometers between serious accidents • Data communications can help further reduce serious accidents – The error rate for vehicle safety data communications probably needs to be better than 10-7 – To achieve this error rate, safety data messages should be sent using at least two different media with substantially different characteristics, e.g., microwave (5.9 GHz) and millimeter (62-63 GHz) • To achieve the necessary reliability, the allocated frequencies should be dedicated to safety and identical across regions – Vehicle manufacturers should not be faced with slight differences in data communications in different regions when lives are at stake TIA – Shields – ITS GSC-9, Seoul 7 ITS Communications Update • Informational Note--ITS involving 4.9 GHz: TIA Engineering Committee TR-8 is taking on the work of developing standards for broadband data systems (within newly established TIA TR-8.8) involving the 4.9 GHz spectrum and may have implications or relations to ITS activities. • Other ITS Reference: TIA Contribution (document) under GSRC-2, Item 5.6, entitled ITS Communications Update.
