This work presents a novel approach for concurrent synchronous multi-lane communications between Road Side Units (RSUs) and On-Board Units (OBUs), based on the flexibility of software defined radio receivers. By exploiting frequency multiplexing, the proposed technique guarantees the concurrent communications of two RSUs with the same OBU across the road, without any need for additional selective filtering. The technique applies to the electronic toll collecting systems operating under the ETSI ES200674 communication standard, in which it enables the free-flow application. Experimental validations show a behavior backing the suggested technique, and field tests demonstrate a communication area compatible with the real-case scenario usage.
