Patent ID: 7907908

Claim:
A radio access point comprising: an access terminal function portion which includes a transmitter part for transmitting signals and a receiver part for receiving signals, and which serves to test the radio access point; either of a receiver of one loop and receivers of two loops, for receiving forward signals that are transmitted from said access terminal function portion and a communication terminal; a transmitter for transmitting reverse signals that are transmitted to said access terminal function portion and said communication terminal; a path switch part for switching to connect an input end of said receiver with an antenna or not, and for switching paths of the signal from said transmitter and the signal toward said receiver; and a controller which receives a test start command, terminates the input end of said receiver by said path switch part in compliance with the command, connects a desired one of said transmitter and said receiver with said access terminal function portion and, controls a measurement path diagnosis which acquires a first reception power value of said receiver in the case of connecting said receiver with said transmitter part of said access terminal function portion and, in which failures of said receiver are diagnosed depending upon whether or not a difference between the first reception power value and a predetermined first reception power expectation lie within predetermined ranges.
