The future of private microwave radio networks in the era of national broadband networks
The transition of private networks to IP standards opens up a plethora of backhaul options. These range from simply replacing traditional TDM-based backhaul with IP-based transmission systems of similar capacity to placing the backhaul in the hands of commercial telecommunications carriers and their low-cost IP service options. The promises of ubiquitous broadband coverage from national broadband networks (NBNs) potentially add even more confusion to this already complex design environment. This paper is based on the recent experiences of ATI in the Australian environment of providing high-capacity broadband backhaul in remote regional areas as well as urban areas. It touches on the important network variables as well as backhaul transmission characteristics in order to provide a set of selection and design guidelines applicable to most network cases, with particular focus on network security and cost.
