	DSRC - Dedicated Short Range Communications
		Dedicated Short Range Communications (DSRC) is a block of spectrum in the 5.850 to 5.925 GHz band allocated by US FCC to enhance the safety and the productivity of the transportation system”.
		DSRC is a medium range communication service intended to support both Public Safety and licensed Private operations over roadside-to-vehicle and vehicle-to-vehicle communication channels.
		DSRC complements cellular communications by providing very high data transfer rates in circumstances where minimizing latency in the communication link and isolating relatively small communication zones are important.

		The DSRC prototype initiative is a prerequisite for introducing new roadway applications such as issuing alerts to drivers about impending intersection collisions, rollovers, weather-related road hazards, or warning a driver that his vehicle is going too fast to safely negotiate an upcoming curve.
		DSRC and traditional RFID differ in other ways: DSRC will use a modulation type that breaks data down into small parts and transmits them in parallel within a wide channel, whereas traditional RFID sends everything in series over a narrow channel.
		The DSRC Industry Consortium, which was formed in late 1999 and held its first official meeting in February 2000, will receive $1.3 million from the FHWA in the first phase of the DRSC prototype initiative.

	Dedicated Short Range Communications (DSRC) by ARINC
		In North America, 5.9 GHz Dedicated Short-Range Communications (DSRC) systems are being developed to support a wide range of public-safety and private operations in roadside-to-vehicle and vehicle-to-vehicle environments for the transportation industry.
		DSRC has several key benefits: It complements cellular communications, where time-critical responses (less than 50 ms) or very high data transfer rates (6-54 Mbps) are required in small zones with license-protected authority, and it enables a new class of communications applications that can support future transportation systems and needs.
		For example, ARINC wrote the first definitive reports on DSRC spectrum requirements in 1996, which formed the basis for the 5.9 GHz spectrum petition to the FCC.

		NTIA believes that since many of the technical parameters for the DSRC equipment to be used in the United States have now been finalized, it is appropriate for the DOT to initiate another study to determine the effectiveness of the current coordination zones.
		DSRC is a short to medium range communications service that supports both public safety and private operations in roadside-to-vehicle and vehicle-to-vehicle communication environments.

	ARRLWeb: ARRL Comments in Response to RM-9096
		Finally, the League argued that, though DSRC applications may not necessarily be incompatible with incumbent and future amateur use of the spectrum, and notwithstanding the fact that ITS America reassures all concerned that there is such compatibility, the record in this proceeding to date was insufficient to demonstrate such.
		Therefore, to the extent that an allocation for DSRC systems above 40 GHz would avoid the issue entirely, and because the cost implications of that alternative are not shown to be a significant obstacle,[6] the League suggests either that the DSRC allocation be entirely above 40 GHz.
		If DSRC devices were classified as Part 15 devices, amateur operations in the band would be unencumbered, since Part 15 devices would not be entitled to interference protection and would not be permitted to cause such.

	FCC unleashes privately owned short range communications networks
		The Federal Communications Commission has quietly opened up licensing of the 5.9 GHz frequency band in the US, paving the way for private sector deployment of Dedicated Short Range Communications (DSRC) systems along America's roads and highways, according to market analyst firm ABI Research.
		Benjamin thinks not: "The instigator for DSRC will be the addition of transmitters to the vehicles by automotive OEMs," he says, adding, "Right now there are no vehicles that can actually use the signals at 5.9 GHz.
		ABI Research's report, "Dedicated Short Range Communications (DSRC)" analyzes RFID and Wi-Fi based offerings for the vehicle, along with competing and supporting technologies for DSRC networks, in addition to potential business models.

	FCC Creates Opportunities In 5.9-GHz Band (Site not responding. Last check: 2007-11-03)
		Private-sector deployment of Dedicated Short Range Communications (DSRC) systems along roads and highways in the United States received a huge lift by the United States Federal Communications Commission (FCC) recent ruling to open the 5.9-GHz band to this application, according to market research firm ABI Research (Oyster Bay, NY).
		The firm's research report - Dedicated Short Range Communications (DSRC) - notes that any organization can buy a nonexclusive license for a relative affordable feed that allows them to erect towers in defined geographic area potentially as large as an entire state.
