Car-to-car communications will spawn a generation of dedicated RF signal analysis

November 18, 2013 // By Christoph Hammerschmidt
An essential contribution to Intelligent transport systems (ITS) will be vehicle-to-vehicle (V2V) and vehicle-to-infrastructure (V2I) communications, which will use the IEEE 802.11p protocol standard. Testing solutions for this protocols are now falling in place.

Rohde & Schwarz has added to the features of its FSV and FSW signal and spectrum analysers to support the IEEE 802.11p wireless standard. The options, with designations FSV-K91p and FSW-K91p, are designed in particular for 812.11p-compliant signal analysis in V2x applications and Intelligent Transport Systems. Spectrum measurements are carried out according to IEEE 802.11p, along with analysis of the modulation quality of these signals. Pre-defined spectrum masks can be used to verify that the transmitted signal complies to the requirements of ETSI and FCC. FSW is designed for deployment in a development environment, FSV the vendor for both development and production environments.

The IEEE 802.11p wireless standard is used for communications between vehicles as well as between vehicles and the infrastructure - examples are traffic lights, traffic management systems and dynamic road signs. Operating in the licensed ITS band between 5.85 and 5.925 GHz, the standard regulates wireless access in vehicular environments and specifies stringent requirements in terms of spectral purity and permissible adjacent channel power
