Analysing IEEE 802.11p for vehicle-to-vehicle communications

November 29, 2013 // By Graham Prophet
Rohde & Schwarz has expanded the functions of its FSV and FSW signal and spectrum analysers to include the IEEE 802.11p wireless standard. The FSV-K91p and FSW-K91p measurement options are designed for IEEE 802.11p compliant signal analysis in vehicle-to-vehicle (V2V) applications and intelligent transport systems (ITS).

R&S FSV and FSW signal and spectrum analysers equipped with the new software options support developers of vehicular communications components, modules and systems. They can perform spectrum measurements in line with IEEE 802.11p and analyse the modulation quality of the signals. Predefined spectrum masks can be used to verify that the transmitted signal is ETSI/FCC compliant.

IEEE 802.11p is used for communications between vehicles as well as between vehicles and roadside infrastructure such as traffic lights, traffic management systems and traffic signs. IEEE 802.11p regulates wireless access in vehicular environments (WAVE). It also specifies stringent requirements in terms of spectral purity and permissible adjacent channel power. It operates in the licensed ITS band from 5.85 GHz to 5.925 GHz.
