DSRC Packet Sniffer, a vehicle-to-vehicle communication technology is under demo

Sirit Inc has announced that they will demonstrate a Dedicated Short Range Communications ("DSRC") Packet Sniffer at the ITS World Congress. The Packet Sniffer is a listening device used to independently verify transmitted DSRC data and protocols. The new test tool is the first device to verify IEEE 802.11p and 1609 standards based "Over-the-Air" transmissions.

DSRC Overview
5.9GHz DSRC is a communication technology designed to provide standards-based, interoperable, low latency, highly secure, high-bandwidth vehicle-to-vehicle and vehicle-to-infrastructure communications enabling a broad range of applications. Its development represents a critical milestone toward the realization of the combined goals of reduced accidents and fatalities as well as improved mobility - all on one platform. A prominent attribute of 5.9GHz DSRC is that it's based on open standards and can be built by any supplier.
DSRC Benefits
As an independent single-channel listening device, the 5.9GHz Packet Sniffer is a low-cost autonomous protocol analysis tool that verifies transmitted data against published VII protocols. The software runs on a Windows XP laptop and captures and decodes over-the-air data packets. The single-channel radio listening device detects DSRC units within a short range and monitors either the control channel or service channel. It decodes WSA ("WAVE Service Announcement"), WSM ("WAVE Short Message") and UDP ("User Datagram Protocol") messages per IEEE 1609 and SAE J2735 standards along with embedded security certificates. If the data transmitted over the 802.11p radio does not meet protocols, the test tool reports the data seen and provides information on whether the data can be decoded properly. The Packet Sniffer represents a critical step for Sirit's customers by providing a low cost verification tool for OmniAir 5.9GHz DSRC device standards compliance program.
Sirit originated its work with the DSRC Industry Consortium with the responsibility of testing the developed technology against the emerging 5.9GHz standards. Currently, Sirit continues its RF Communications testing role in VII proof of concept development.
