1. 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.
