Abstract
Provided is a radio communication device including a reception unit that receives a radio signal, a measurement unit that measures a field intensity of the radio signal received by the reception unit, a determination unit that determines whether the radio signal received by the reception unit satisfies a predetermined condition for a noise component, and an estimation unit that estimates a distance from a transmission source device of the radio signal based on the field intensity of the radio signal determined by the determination unit to satisfy the predetermined condition.
Claims12
A radio communication device comprising:
- a reception unit that receives a radio signal;
- a measurement unit that measures a field intensity of the radio signal received by the reception unit;
- a determination unit that determines whether the radio signal received by the reception unit satisfies a predetermined condition for a noise component;
- and
- an estimation unit that estimates a distance from a transmission source device of the radio signal based on the field intensity of the radio signal determined by the determination unit to satisfy the predetermined condition;
- wherein the estimation unit calculates an average value of the field intensity of the radio signal determined by the determination unit to satisfy the predetermined condition, determines in which of defined average value ranges the average value is included, and estimates the distance from the transmission source device of the radio signal to be a distance corresponding to the average value range in which the average value is determined to be included.
