METHOD AND APPARATUS TO FACILITATE USING MULTIPLE CARRIER FREQUENCIES |
摘要 |
A wireless radio frequency transmitter (400), upon detecting (101) an end user assertion of an end user interface and in automatic response thereto, uses a first rolling carrier frequency to transmit (102) a message. Upon then determining (104) that the end user is continuing to assert this end user interface, this transmitter then re- transmits (105) that message using a predetermined fixed carrier frequency. By one approach, the first rolling carrier frequency is selected from amongst a pool of candidate carrier frequencies using a carrier frequency calculation formula. By another approach, this carrier frequency is selected from one or more tables that comprise a plurality of different carrier frequencies. |
