For several years, automobile makers and government agencies have sought ways to improve safety on roadways and effectively manage traffic flow. As wireless communication systems are advancing, the vision of automobiles talking to each other and to roadside units is becoming a reality. These planned automotive wireless communication systems are known as ITS (Intelligent Transportation System). This paper will provide an overview of the current status of the ITS worldwide with a focus on the IEEE 802.11p PHY. Additionally, the paper provides information on test and measurement solutions for devices and components used in ITS.

Spectrum that was previously reserved for TV broadcasting is being freed up in many countries for use under the new Long Term Evolution (LTE) mobile radio standard (keyword: 'digital dividend'). As a result, numerous coexistence scenarios are possible. So network operators and manufacturers from both the mobile radio and the broadcast sector have a vital interest in avoiding any interference and performing in-depth testing of their products. Rohde & Schwarz offers a wideranging product portfolio for such applications. This Application Note presents Test & Measurement equipment for the broadcast and mobile radio sector and discusses some possible test setups.

Automating measurement setups is advantageous for multiple reasons. It saves time in case of repeated measurements and in hazardous environments, instruments can be operated from a distance. The measurements are repeatable because they are always performed with a defined procedure, leading to higher test confidence.But in remote control applications, users often perceive synchronization and binary transfers as challenging. Therefore, this application note focuses on binary transfer of data to and from the instrument and shows code example to demonstrate the ease of use.
