A.wlan service-template 1 has been applied to the radio of the AP, you need to cancel the application first and then enter the command "wlanservice-template 1 crypto". If wlan service-template 1 is not applied, directly enter the command "wlan service-template 1" crypto".

B.You cannot modify the encryption type of the existing wlan service-template 1. You can only delete the original service-template 1, and then create a new service-template 1 through the command "wlan service-template crypto" to modify it to the purpose of the encryption type, but if wlan service-template1 has been applied to the radio of the AP, the relevant application needs to be released first.

C.First try to enter "service-template disable" in service-template 1, then enter "wlan service-template 1 crypto" in the global view, and finally enter in the service-template 1 view.

D.Enter the command "wlan service-template 1 crypto"

A.The WLAN combined channel expansion solution can increase the overall WLAN system capacity by combining two APs using different channels.

B.When using this combined circuit expansion solution, the insertion loss introduced by the WLAN combiner is about 2dB, which needs to be taken into account when calculating the signal strength.

C.During project implementation, if FIT AP is used for WLAN dual-frequency combining, it is recommended to enable the load sharing function of the wireless controller + FIT AP, so that wireless users can be evenly connected to two APs, avoiding a lot of users on one AP. Rarely happens to users on another AP.

D.At present, this expansion program due to the restriction device characteristics, supports only channel 1 and channel 11 a road expansion, but the two-port multiplexer which then channel 1 of the AP, which then channel 11 of the AP and not strictly limited.

A.The interference produced by FM radio is narrow-band interference.

B.The signal of each frequency point in the spectrum analyzer should be a standard sine wave if viewed through an oscilloscope.

C.In theory, noise will uniformly affect all frequencies of radio signals, while narrow-band interference is noise that is only in a small range of frequencies.

D.There are two common methods for signal analysis: time domain analysis and frequency domain analysis. Time domain analysis usually uses an oscilloscope to view the signal, while frequency domain analysis usually uses a spectrum analyzer.
