ABSTRACT:
One embodiment of the present invention relates to a method of limiting data loss in a point-to-multipoint communication system. Data is transferred on a communication channel among network nodes of the point-to-multipoint communication system according to an initial frequency band plan. If a characteristic of the communication channel changes, then data is transferred among the network nodes according to a modified frequency band plan that differs from the initial frequency band plan.
