Wireless communication apparatus and interference detection method

摘要

According to one embodiment, a wireless communication apparatus is provided with first and second determination units. The first unit determines based on a first carrier sense threshold whether busy state or not and specifies a first time when busy state is determined with the first threshold, and determines based on a second carrier sense threshold smaller than the first threshold whether busy state or not and specifies a second time when busy state is determined. The second unit determines, if at least busy state is determined based on the second threshold and the second time precedes a reference time equal to or earlier than the first time, to perform processing for avoiding interference.

主权项

1. A wireless communication apparatus comprising:
a buffer configured to store a received frame; a first processor configured to detect a first busy time when a received signal strength indication (RSSI) becomes equal to or more than a first threshold, and configured to detect a second busy time when the RSSI becomes equal to or more than a second threshold, the second threshold being smaller than the first threshold, and configured to perform processing to avoid interference, if the second busy time precedes the first busy time, wherein the processing is at least one of changing a channel to be used, changing a transmission rate, issuing a notification to a user, or changing an interframe space.
