Systems and methods for: suggesting network topologies for a wireless communication network such as a millimeter-wave network; using drones for determining a line-of-sight condition between pairs of geospatial locations where communication nodes in the network are to be placed; and wirelessly interconnecting pairs of nodes in the network according to the a line-of-sight conditions previously determined using the drones. The drones may test for a line-of-sight condition using any number of methods, including laser range-finding, signaling between two of the drones, and pattern matching of visual imagery. A network planning tool may be used to suggest the network topologies, communicate and control the drones, and come to a final conclusion regarding the actual network topology selected, the placement of the communication nodes, and the specific wireless links to be used in interconnecting the nodes in the final network.
