Abstract
A wireless access point apparatus includes a mixer, an analog low-pass filter (ALPF), an analog-to-digital converter (ADC), a radar detector and a controller. The mixer is configured to mix a wireless signal and a carrier signal for performing frequency conversion on the wireless signal. The ALPF with a passband is configured to perform filtering on the wireless signal, so as to filter out a signal component of the wireless signal out of the passband. The ADC is configured to convert the wireless signal from an analog form to a digital form. The radar detector is configured to detector whether the wireless signal includes any radar signal. The controller is configured to adjust a carrier frequency of the carrier signal depending on a determination result of the radar detector for switching between a dynamic frequency selection (DFS) channel, a non-DFS channel and a composite channel.
