Abstract
A network apparatus for self-testing network connectivity, a method thereof, and a method of analyzing frequency spectrum. The invention includes a link mode and a diagnostic mode. In the diagnostic mode, the MAC self-tests the network apparatus for network connectivity at least in signal quality, link quality, and quality of service by generating output signals traveling from the transmitter to the receiver, thus providing a simple, low power consuming, and reliable means for troubleshooting errors. The method of analyzing frequency spectrum eliminates the need of an expensive spectrum analyzer by utilizing the transmitter to output signals detectable by the receiver, then calculating power level differences between selected channel and its adjacent channels of the channels assigned to the receiver, and comparing the calculated power level differences with a plurality of pre-determined threshold values stored in a memory controlled by the MAC in order to meet standards and specifications.

18. A method of self-testing network connectivity applied in a network apparatus, the network apparatus comprising a receiver, a transmitter, and an antenna, the method comprising:
-
outputting by the transmitter a plurality of output signals to the receiver;
optimizing uplink capability by tuning the transmitter, such that the output signals are output substantially at a predetermined maximum power level satisfying a predetermined transmitter packet error rate (PER);
checking downlink capability by tuning the transmitter, to see if the output signals are output substantially at a predetermined minimum power level satisfying a predetermined receiver PER; and
checking crosslink capability by tuning the transmitter to see if the output signals are output at a characteristic crosslink power level satisfying a predetermined link quality indicator (LQI) and a predetermined indicator of quality of service (IQoS). - View Dependent Claims (19, 20, 21, 22, 23)
