Various embodiments of the present invention relate to wireless network management. One specific example relates to efficient radio frequency (RF) spectrum management involving multiple mobile vehicles, whereby a system and/or a method of the invention achieves greatly improved spectral efficiency in the assignment of frequency bands to communications channels between the vehicles and/or stationary ground stations. Other examples of the present invention provide systems and methods to analyze the RF emissions resulting from the motion of transmitters and/or receivers through airspace with the help of five-dimensional quanta of space (x, y, z), time and frequency to assign frequency bands to test plans (including previously-validated test plan(s) and/or to-be-validated test plan(s)). In one specific example, the analysis is directed to the assignment of frequency bands with and without reuse.

A MOAF algorithm is used to resize cells for balancing capacity. The MOAF algorithm bases its decision on a cell and all other cells which the algorithm decides are sufficiently close in a propagation sense to affect the results. The MOAF algorithm also automatically determines those cells in an area which are most heavily loaded and those cells which are lightly loaded. The MOAF algorithm will only decrease the size of a cell if it determines specific adjacent cells that are willing and able to accept the load, and the MOAF algorithm will increase the size of a cell only if there is a nearby heavily loaded cell that requires the removal of load. Moreover, the MOAF algorithm can be tuned (via the threshold parameter T) to shift the focus of the optimization from avoidance of coverage holes to the avoidance of creation of excessive handover legs. Because the changes are electrical rather than physical they can be deployed instantaneously via the network management system thus saving the cost of sending a field crew to the site. Moreover, it is possible to make these changes much more frequently than has been possible in the past thereby permitting the optimization of the network to be done in near real time to meet the temporal changes in the geographic distribution of customers.
