Abstract

A method for positioning network devices includes receiving network parameters for a network and determining corresponding installation locations for the end devices based on the network parameters. The network includes at least one network backhaul, relay devices in communication with the network backhaul, and end devices in communication with the relay devices or the network backhaul. The end devices are configured to wirelessly communicate with user devices at the corresponding user locations. The method also includes determining communication connections between at least one of: the end devices and user devices; the relay devices and the at least one network backhaul; the relay devices and the end devices; or the end devices and the at least one network backhaul. The method further includes generating a network topology indicating the determined corresponding locations for the end devices and the determined communication connections.
