Two new standards for short-range wireless communication are under development. These are DSRC (Dedicated Short Range Communications) at 5,9 GHz and ZigBee. This study shall serve as a basis for an assessment of the suitability of the communication systems. Primarily, to increase security for moving and unprotected road-users. Earlier versions of the DSRC-standard have been developed to mainly support use of ETC-services (Electronic Tool Collection). The new DSRC-standard aims to support ETC-services as well as new and future services. These services are going to be supported between vehicles and roadsides as well as between different vehicles. ZigBee are going to support use of applications that do not have any special requirements on high data rates but instead a strict requirement on low power consumption. The battery must last for months or even years. The study contains: analysis of each communication system, account of advantages and disadvantages with both communication systems and also evaluation of the communication standards. The evaluation will answer questions like: What potential do these standards have to become widespread? In what ways are these standards technically interesting? What applications can be used with the standards?
