  • Energy-efficient indoor localization system and a method of reducing power consumption of a radio badge in the indoor localization system
    Patent number: 8159333
    Abstract: A method of reducing power consumption of a radio badge in a localization system is disclosed, in which the radio badge is carried by a tracked target and is provided with a pedometer for detecting a footstep count of the tracked target. The method includes: estimating a velocity of the radio badge according to the footstep count detected by the pedometer; calculating a sleep time from the velocity of the radio badge; and controlling the radio badge to discontinue emitting radio signals during the sleep time. An indoor localization system that performs the method is also disclosed.
