Abstract
A communications system includes at least two communications units, each communication unit including a transmitter capable of transmitting to the other unit at different power levels and on different frequencies, the power levels and frequencies of transmission being controlled by a mode control unit in response to indicators of transmission quality and reliability, wherein the mode control unit initially establishes a minimum power output of the transmitter at a fixed frequency to establish communications and if reliable communications cannot be maintained, increasing the level of output power of the transmitter until reliable communications are established as indicated by signals returned from another unit in the communications system, and wherein the mode control unit changes the output frequency of the transmitter from a single frequency mode to a time division spread spectrum mode if the required power output level of the transmitter exceeds a first predetermined threshold.
