A system and method for conducting dynamic RF-link margin tests in an electronic toll collection for non-stationary vehicles travelling up to highway speed. The system maintains a list of candidate transponders and, during the course of a normal toll collection, if a transponder is on the list then the system schedules a margin test for a later handshake in the capture zone. At a location at or near the peak margin test the system conducts a margin test during one or more of the reader-transponder handshakes. The attenuation may be dynamically controlled by the system using a variable attenuator in the RF path from the reader RF module to the antenna. Distributing the margin measurement over multiple passes of a vehicle through the capture zone provides for a highway speed method of measuring link margin.

NETWORK NODE FOR AN AD-HOC NETWORK AND PROCESS FOR PROVIDING APPLICATION SERVICES IN AN AD-HOC NETWORK
The invention relates to a network node (N i) for an ad-hoc network having a plurality of network nodes (N j) of the same type, which provide one another with application services via wireless connections (2), wherein the network node (N i) generates a list (LAST i) of all application services (S n) provided to it by other network nodes (N j) with associated quality classes (QEC in) and makes this list (LAST i) available to other network nodes (N j) as list of the application services (S n) provided by it with such quality classes (QEC in), wherein said quality class (QEC in) is at least dependent on the number of consecutive network nodes, via which the application service (S n) is provided, and the quality class (QEC jn) specified by the last of these network nodes. The invention also relates to a process for providing application services in an ad-hoc network.
A method and system for determining right of way for a plurality of mobile units at an intersection. The method and system include collecting position and movement information about the plurality of mobile units approaching the intersection; storing a plurality of rules about right of way at the intersection; accessing information about geometry of the intersection; calculating which one or more of the plurality of the mobile units have right of way to enter the intersection, responsive to the position and movement information, the stored rules and the information about geometry of the intersection; and wirelessly transmitting right of way indication signals to one or more of the plurality of the mobile units.
