Systems and methods are described for automated sector creation in greenfield physical radiofrequency (RF) communication network infrastructures. For example, a network operator is granted licenses to use multiple spectrum blocks in multiple geographic regions for which the network operator does not currently have physical infrastructure. An RF network design defines a number of template antennas located at template site locations to meet a link budget over a target coverage area. For each template site location, embodiments can automatically compute sectors based on the associated template antennas and local spectrum licensing information. The computed sectors can effectively define a physical network deployment, including locations and configurations for sector antennas, by which the network operator can provide a desired quality of coverage to subscribers in the target coverage area.
