3 Scope of Working Group 4 ITS WG 4 works on PHY & MAC standardisation issues ITS-G5A ITSG5B ITS-G5C ITS-IR ITS-G60 IMT Bluetooth GNSS VHF/UHF (European profile) in GHz to GHz frequency range (European Profile) in GHz to GHz (European profile) in WLAN 5.4 GHz frequency range Infrared 60GHz millimetre wave Public cellular services such as 2G/3G, IMT Bluetooth (when referring to satellite based positioning information) Air interface below 1 GHz based on existing PMR/PAMR regulation & Harmonized Standards 3

4 European Profile Standard ETSI ES Published by ETSI on January 14, 2010 after successful completion of the ETSI Membership Voting procedure. Based on the completed work for 5.9 GHz ITS spectrum allocation in Europe, WG 4 created a new European profile standard for the PHY and MAC layers. In 2010, there will be a revision of this deliverable and is also expected to become European Norm. Harmonized Standards EN for 5 GHz ITS Will be revised to be in line with the European Profile Standard and experience gained from projects. EN for ITS operating at GHz Harmonized European Standard is being created in WG 4. Work on Harmonized European Standards for all media is in ITS WG 4. For the approval process, ETSI TC ERM is involved. ITS WG 4 may also develop new ETSI System Reference Documents in the future (i.e. spectrum requests) in line with the MoU between CEPT and ETSI. 4

7 Related Activities Current ETSI Work Items for ITS G5 (ABC) Mitigation techniques to avoid interference between European CEN Dedicated Short Range Communication (RTTT DSRC) equipment and Intelligent Transport Systems (ITS) operating in the 5 GHz frequency range (related to ETSI Special Task Force 395, EU funded) Transmitter Power Control Mechanism for Intelligent Transport Systems operating in the 5 GHz range - TPC specifications for operation in the 5 GHz range to satisfy: regulatory requirement, congestion control and networking, inter-layer management, further requirements if identified. (related to ETSI Special Task Force 395, EU funded) Intelligent Transport Systems (ITS); Harmonized Channel Specifications for Intelligent Transport Systems operating in the 5 GHz frequency band The specifications for operation in the 5 GHz range to satisfy the harmonized usage of the designated spectrum by control and service channels including usage of channels for road- safety related ITS applications. This will also include transmit and receive restrictions (likely to have implications on TPC). Reference usage scenarios and parameters will be depicted in informative annexes that justify the specifications. Co-channel and adjacent channel interference considerations will be encompassed. 7
