A. Cross-L2 network networking between Fit APs and wireless switches

B. L3 network spanning between FIT AP and wireless switch

C. Cross-WAN networking between FIT APs and wireless switches

D. Direct connection between Fit AP and wireless switch, for small Fit AP network

A. It adopts the working principle similar to sonar, the clocks of receiving and sending are all from the clock of the local AP, which avoids the complex clock synchronization problem of one-way measurement (such as GPS system).

B. The high-precision local clock ensures accurate measurement results and ultimately improves positioning accuracy.

C. Compared with the RSSI value, it is greatly affected by the environmental factors in the transmission process, and the environmental influence on the RTT value is relatively small.

D. The CUPID system adopts the technical route based on the electromagnetic wave transmission time difference RT. In the case of no sampling, a more accurate and stable positioning effect is achieved.

A. Gain

B. bandwidth

C. Power

D. Polarity

A. 2400-2483.5

B. 1900- 1920

C. 1710-1715

D. 825-835

A. 802.1X authentication occurs during the authentication process, and the association process starts after the authentication is completed. The question bank is required for the association process.

B. PSK authentication occurs during the authentication process, and the association process starts after the authentication is completed

C. PSK authentication occurs after the association is completed, and the authentication and encryption information exchange with the AP is completed through eapol

D. 802.1X authentication occurs after the association is completed, and the authentication and encryption trust interaction with the AP is completed through eapol

A. error

B. correct

A. When deploying multiple APs in such areas, it is necessary to consider the channel division between APs. The APs are deployed with poor channels to reduce interference. For example, when three APs are deployed, the channels of AP1, AP2, and AP3 can be separated from each other. Set to 1, 6, 11

B. This type of area is the main WLAN indoor application place, such as comprehensive function area, hotel room, etc. This type of area can be divided into small areas according to rooms, walls, columns, etc., which can be regarded as multiple areas with small radius and few users The combination

C. This type of area can be covered by low-power APs. The coverage method can be carried out according to the coverage method of the area with small radius and few users. When covering, it is necessary to pay attention to the frequency isolation of each AP.

D. Such areas can be covered by an indoor distributed system, and the antenna feeder system of the original wireless network (such as PHS, CDMA, etc.) can be used to combine the WLAN system, so as to achieve the effect of one AP covering a large area.

A. 802.11ax introduces BSS-COLOR to quickly identify BSS and improve signal reception and demodulation efficiency.

B. 802.11ax supports both uplink and downlink MU-MIMO.

C. 802.11ax modulation mode supports 1024QAM.

D. Supports 8-channel bonding with 160MHz bandwidth.

A. AP's version information is wrong

B. Wrong serial number configured on AC

C. Wrong version information for AC

D. Wrong serial number configured on AP

A. 7/8" feeder cable

B. RF matching load

C. 2dBi gain antenna

D. 1/2" feeder cable
