Patent ID: 8890714

Claim:
A radio apparatus comprising: a receiving unit configured to receive a packet signal sent from another radio apparatus; a processing unit configured to process the packet signal received by said receiving unit; a measurement unit configured to measure a received power of the packet signal received by said receiving unit; a monitoring unit configured to monitor a variation in the received power measured by said measurement unit; and a notification unit configured to send a notification such that, when the received power measured by said measurement unit is smaller than a first threshold value and when the received power increases in such a manner that the variation monitored by said monitoring unit is larger than a second threshold value, said notification unit starts to convey information reflecting content of the packet signal processed by said processing unit, and when the received power measured by said measurement unit is larger than or equal to the first threshold value, said notification unit starts to convey the information reflecting content of the packet signal processed by said processing unit, regardless of the variation monitored by said monitoring unit.
