Signal analyser supports car-to-x communications standard

November 28, 2013 // By Christoph Hammerschmidt
Rohde & Schwarz has expanded the functionality of its R&S FSV and R&S FSW signal and spectrum analysers to include support the IEEE 802.11p wireless standard for the car-to-x communication. The new R&S FSV-K91p and R&S FSW-K91p measurement options are especially designed for IEEE 802.11p compliant signal analysis in car-to-car (aka vehicle-to-vehicle or V2V) applications and intelligent transport systems (ITS).

R&S FSV and R&S FSW signal and spectrum analysers equipped with the new software options support developers of vehicular communications components, modules and systems. They enable designers to 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.

In the future, intelligent transport systems (ITS) will help reduce traffic congestion and improve road safety. The IEEE 802.11p wireless standard is used for communications between vehicles as well as between vehicles and roadside infrastructures such as traffic lights, traffic management systems and traffic signs. IEEE 802.11p regulates wireless access in vehicular environments (WAVE). It also specifies 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.
