Spread-spectrum changeable base station

A method of using a communication unit used in a spread-spectrum communication system having a plurality of the units which allows for simultaneous communication among a plurality of active units, the method comprising the steps of:

• initiating the generation of a command signal;
• transmitting communication signals at one of two frequencies and transmitting said command signal;
• and
• receiving communication signals at one of said two frequencies and receiving said command signal, whereby upon initiation of said command signal, said command signal is transmitted for receipt by all active units in the system and the unit transmitting said command signal receives communication signals at a selected frequency of said two frequencies and transmits communication signals at another frequency, and whereby upon reception of said command signal from another unit in the system, the unit receiving said command signal transmits a communication signal at said selected frequency of said two frequencies and receives communication signals at said another frequency.

A spread-spectrum communication system having a plurality of communication units which allow for simultaneous communication among a plurality of active units, each communication unit comprising:

• a command signal generator for generating a command signal;
• means for transmitting communication signals at one of two frequencies and for transmitting said command signal;
• and
• means for receiving communication signals at one of said two frequencies and for receiving said command signal, whereby upon initiation of a command signal, said command signal is transmitted for receipt by all active units in the system and the unit transmitting said command signal receives communication signals at a selected frequency of said two frequencies and transmits communication signals at another frequency, and whereby upon reception of said command signal from another unit in the system, the unit receiving said command signal transmits a communication signal at said selected frequency of said two frequencies and receives communication signals at said another frequency.
