ABSTRACT:
A method is provided for transmitting data. A first device generates a first signal having a first duty cycle, comprising a first gated-on portion and a first gated-off portion in a time slot; and a second device generates a second signal having second duty cycle, comprising a second gated-on portion and a second gated-off portion in the same time slot. The first gated-on portion is generated during a first segment of the time slot and the first gated-off portion is generated during a second segment of the time slot, while the second gated-on portion is generated during the second segment and the second gated-off portion is generated during the first segment. Media access control (MAC) can be used to further define positions within time slots and provide error correction, power control, and the like. A preamble can be transmitted at an increased power level to facilitate acquisition.
