Patent ID: 7031657

Claim:
A system for mobile or wireless communication or computation, said system comprising: first unit comprising first antenna, wherein said first unit is mobile or wireless; last unit comprising last antenna, wherein said last unit is mobile or wireless; and said first unit receives data from said last unit, wherein said data is transmitted from said last antenna to said first antenna, wherein said last unit receives said data from a location outside said system, wherein said data is transmitted from said location outside said system to said last antenna, wherein transmission of said data between said first antenna and said last antenna is done at first frequency, and transmission of said data between said last antenna and said location outside said system is done at second frequency, wherein said second frequency is different than said first frequency, wherein said first frequency is chosen from a range of frequency which corresponds to a low radiation power absorption for a specific tissue or part of human body, or which corresponds to a low overall radiation power absorption for whole body of a human or a specific animal, and wherein transmission of said data between said first antenna and said last antenna is done at first power, and transmission of said data between said last antenna and said location outside said system is done at second power, wherein said second power is different than said first power, wherein said second power is larger than said first power.
