IEEE 1609.0:2013 pdf free download – IEEE Guide for Wireless Access in Vehicular Environments (WAVE)Architecture
This architecture guide focuses on the physical entities or subsystems of an ITS architecture, for examplethe U.S. National ITS Architecturc. The National ITS Architecture describes a physical representation(though not a detailed design) of how the system provides the required functionality. Four categories ofsubsystems are identified: Travelers (e.g.,Remote Traveler Support, Personal Information Access), Centers(e.g.，Traffic Management，Emergency Management)，Vehicles，and Field (e.g.，Roadway Payment,Parking Management). The roadside unit (RSU) exists in the “Field”area, and the onboard unit (OBU)exists in the“Vehicle”area. The WAVE communications provide vehicle-vehicle communications andfield-vehicle communications.
4.2 ASTM and the Federal Communications Commission (FcC)
Pursuant to the Transportation Equity Act for the 21st Century, the U.S. FCC, in consultation with theU.S. DOT, allocated the 5.850-5.925 GHz band to DSRC in October 1999.(See 5.6.) On November 7,2002, the FCC adopted a Notice of Proposed Rule Making (NPRM) seeking comment on proposed DSRCservice rules in the 5.9 GHz band, and on December 17,2003, it adopted the DSRC service rules.
To promote the widespread use and evaluation of intelligent vehicle-highway systems technology， theCommission in the DSRC Report and Order FCC 03-0324 [B7] adopted the ASTM E2213-03 Standard(ASTM-DSRC)[B1], which was supported by most commenters and which had been developed under anaccredited standard setting process.To achieve interoperability, allow open cligibility, and encourage thedevelopment of a market for equipment that will meet the needs of public safety DSRC licensees, the rulesadopted by the FCC require all DSRC operations in the 5.9 GHz band to comply with the ASTM-DSRCstandard. DSRC Roadside Units (i.e., communication units that are fixed along the roadside) are licensedunder Part 90 Subpart M of the FCC rules(“Intelligent Transportation Systems Radio Service”).RSUlicensees receive non-exclusive geographic-area licenses authorizing operation on seventy of the seventy-five megahertz of the 5.9 GHz band.OBUs are licensed by rule under new Subpart L of Part 95 of the FCCrules; OBU operation is not geographically restricted by FCC license.
Since 2003, work has continued on IEEE standards for the 5.9 GHz band, making the FCC reference to theASTM-DSRC standard obsolete. lt is currently expected that equipment deployed in the 5.9 GHz band inthe U.S. will be compliant to the IEEE 1609 family of standards and IEEE Std 802.11-2012.
4.3 IEEE standards
4.3.1 Trial-use WAVE standards-historical
In 2006 and 2007, a set of IEEE 1609 standards were adopted for trial-use. The trial-use standards wereused to demonstrate and prove the WAVE architecture and protocols, with the resulting lessons learned fedback into full-use standards published in 2010 and beyond (see Annex F for an overview of field trials, and4.3.3 for a description of subsequent standards). These EEE 1609 trial-use standards,which weredeveloped for use with IEEE Std 802.1 1p (now IEEE Std 802.11-2012; see 4.3.2), are depicted in Figure 1and described following.
4.3.2IEEE Std 802.11
IEEE Std 802.11-2012 specifies one medium access control (MAC) sublayer and several physical layers(PHYs) to provide wireless connectivity among fixed, portable, and moving stations(STAs) within a localarea.IEEE Std 802.11p-2010 [B12], now incorporated in IEEE Std 802.11-2012,standardized a smallnumber of extensions to IEEE Std 802.11-2012 for operating outside the context of a basic service set(OCB, i.e., with the dot11OCBActivated parameter set to true), that is,supporting the types of vehicularscenarios required for WAVE system operation.IEEE Std 802.11p-2010 [B12] also standardized the 5.9GHz OFDM PHY (5.850-5.925 GHz in the U.S., 5.855-5.925GHz in Europe), channel bandwidths,operating classes, transmit power classification, transmission masks, and the alternate channel and alternateadjacent channel rejection requirements.
