18、tion:3.1.1 onboard unit (OBU)an onboard unit (OBU) is aDSRC transceiver that is normally mounted in or on a vehicle,but which in some instances may be a portable unit. An OBUcan be operational while a vehicle or person is either mobile orstationary. The OBUs receive and contend for time to transmito

19、n one or more RF channels. Except where specificallyexcluded, OBU operation is permitted wherever vehicle opera-tion or human passage is permitted. The OBUs mounted invehicles are licensed by rule and communicate with roadsideunits (RSUs) and other OBUs. Portable OBUs are also licensedby rule. OBU o

30、ables accurate and valid message deliverywith communication units that are primarily mounted inhigh-speed moving vehicles. These communications may oc-cur with other units that are: (1) fixed along the roadside orabove the roadway; (2) mounted in other high-speed movingvehicles; (3) mounted in stati

31、onary vehicles; or (4) portable orhand-held. Communications may also occur between station-ary or low-speed mobile units and fixed or portable units on theroadside or off the road, in private or public areas. However,most IEEE 802.11 systems implement communications be-tween stationary units or mobi

32、le units moving at low speeds.High speeds are considered those achieved by the generalpublic and emergency vehicles on North American highways.Low speeds are considered as walking to running paces.(2) DSRC devices must be capable of transferring mes-sages to and from vehicles at speeds of 85 mph wit

33、h a packeterror rate (PER) of less than 10 % for PSDU lengths of 1000bytes and to and from vehicles at speeds of 120 mph with aPER of less than 10 % for PSDU lengths of 64 bytes.(3) As explained in the definitions, in-vehicle communica-tions units are called onboard units (OBUs). Communicationunits

34、fixed along the roadside, over the road on gantries orpoles, or off the road in private or public areas are calledroadside units (RSUs). The DSRC RSUs may function asstations or as access points (APs) and DSRC OBUs only havefunctions consistent with those of stations (STAs). The com-mon function bet

35、ween all RSUs is that these stationary unitscontrol access to the RF medium for OBUs in their commu-nication zone or relinquish control to broadcast data only.(4) In order to accommodate the more dynamic environ-ment with essentially the same radio technology and providepriority to public safety com

36、munications, DSRC uses a differ-ent channel access strategy than IEEE 802.11 units andemploys additional operating rules. This additional systemmanagement strategy is described primarily in the IEEEControl Channel and Service Channel standard (underdevelopment), number TBD.E2213 03 (2018)2(5) The es

37、sence of this strategy is the identification of acontrol channel and service channels, a system of priorityaccess, and mandatory service channel data transfer time limitswhile in motion.(6) DSRC uses a unique ad hoc mode. The DSRC ad hocmode is used on all DSRC channels as the default mode ofoperati

38、on. However, it is the only mode of operation on thecontrol channel. In this mode, the BSSID is all zeros and thereis no distributed beaconing mechanism. An OBU nominallylistens on the control channel for messages or applicationannouncements and a data exchange channel assignment, butdoes not scan.

39、The IEEE 802.11-1999 management frames arereceived and acknowledged but not acted upon in the DSRC adhoc mode.(7) RF power, sensitivity, and antenna pattern are intendedto be referenced to a standard location on the vehicle. Thisstandard location is intended to be the front bumper of apassenger vehi
