Different types of terrain may require specific types of network connections in order to adequately cover the region over which data communications are needed. More demanding terrain may require a larger number of intermediate nodes or possibly larger higher-gain antenna systems and mounting structures. Expansion and Growth - Will your network need to expand or adapt to changing conditions over time? Mesh networks are ideally suited for *ad hoc* growth and least cost routing based on the availability of nodes. As more devices are added to the network, however, a simple *ad hoc* mesh topology will not properly scale in size. It could result in increased latency on the network, with some network segments becoming almost unusable if application response time thresholds are exceeded. A growing network will probably require a different well-designed topology that routes data traffic efficiently in order to reach its intended destination. + Will your network need to expand or adapt to changing conditions over time?

Depending on the characteristics of the AREDN® implementation, this digital data network can operate at near-Internet speeds with many miles or kilometers between network nodes. A foundational design goal of the AREDN® project is to minimize the technical expertise that is normally required to configure a robust radio network. Devices running AREDN® firmware are in many ways self-configuring so that users without a background in IP networking can easily build or connect to a local RF network. As mentioned in a recent `Amateur Radio Digital Communications (ARDC) `_ annual report, "AREDN® software allows volunteers to set up a node with minimal expertise and effort, and because the software configures the network automatically, advanced network technology is not needed."
