This report provides the background information on analog and digital communication and a review on the WAN and LAN technologies currently used by road agencies. It also describes the future WAN/LAN technologies including their use within the new National Broadband Network (NBN) infrastructure that will provide increased connectivity through more bandwidth and faster communication speed. These technologies were then compared on outsourcing models, risks and costs amongst other criteria. The issue of network availability, latency, resilience and security also receives attention.
