Radio access point testing method and testing apparatus

An access point having a plurality of sectors and performing radio communication with a radio access terminal in one of the sectors, the access point comprising:

• a main signal processing unit including:
• a plurality of antennas for each sector;
• radio transmission parts for each sector connected with one of the antennas and for transmitting radio signals to the radio access terminal through the connected antenna;
• and
• radio reception parts for each sector connected with one of the antennas and for receiving radio signals from the radio access terminal through the connected antenna,
• an access point controller;
• and
• a test function unit including:
• an access terminal function portion which has a communication function same as or similar to a communication function of a radio access terminal;
• a first switch for selecting the sector, which is an object of a test designated from among a plurality of tests and performed using the test function unit, from among the plurality of sectors;
• a second switch for selecting the antenna, which is the object of the test performed using the test function unit, from among the plurality of antennas of the sector which is the object of the test and is selected by the first switch;
• and
• a test function controller,
• wherein the main signal processing unit further includes, for each sector:
• a third switch for connecting the antenna, the radio transmission part and the test function unit through a directional coupler and for selecting one of a path for transmitting packets from the radio transmission part to the test function unit passing through the directional coupler and the antenna and, a path for transmitting packets from the radio transmission part to the test function unit passing through the directional coupler and not passing through the antenna;
• a fourth switch for connecting the antenna, the radio reception part and the test function unit through a directional coupler and for selecting one of a path for transmitting packets from the test function unit to the radio reception part passing through the directional coupler and the antenna and, a path for transmitting packets from the test function unit to the radio reception part passing through the directional coupler and not passing through the antenna.
