文摘Discusses how to assign a set of noninterference radio channels to a symmetric network of transmitter location over a large planar area, the minimum of the span and the assignment of the channels with the changing of minimum distance among the same channels and the changing of the minimum difference among the adjacent channels. The minimum interval in the frequency spectrum of 9 interger channels is proved and obtained by using the graphic theory and the reduction to absurdity on condition that interference from nearby transmitters is avoided in the whole given grid and the grid spreading arbitrarily far in all directions.
