Dynamic channel assignment (dca)
Dynamic channel assignment (dca) a technique of assigning or reassigning radio channels in a communications system in order to respond to current interference or propagation conditions. Such assignment or reassignment may be made before or during radio transmission. Dca is typically implemented in a distributed fashion, with mobile terminals and/or fixed cell sites taking measurements to determine local interference levels, and then applying an algorithm to choose the best radio channel on which to initiate or reassign communication.
