Abstract
A communication device (12) transmits a communication signal during repetitive time slots. The communication device (12) includes a duty-cycle adjustment signal generator (82) that generates an adjustment signal based on a proximity signal. A controller (54) in response to the proximity signal, adjusts a transmission duty cycle relating to the repetitive time slots for transmitting a communication signal during a time slot. The communication signal is then radiated via an antenna (70).
Claims18
A communication device that transmits a communication signal during repetitive time slots, comprising:
- a proximity detector that generates a proximity signal;
- a duty-cycle adjustment signal generator that is responsive to the proximity signal to generate an adjustment signal;
- a controller that in response to the adjustment signal, adjusts a transmission duty cycle relating to the repetitive time slots for transmitting a communication signal during at least one time slot;
- and
- an antenna that radiates the communication signal.
A method for a communication device to transmit a communication signal during repetitive time slots, comprising:
- generating a duty-cycle adjustment signal in response to a proximity signal;
- adjusting a transmission duty cycle that relates to the repetitive time slots for transmitting a communication signal during at least one time slot, in response to the adjustment signal;
- and
- radiating the communication signal.
