C. Load status of each AC

D. Configuration files of the respective ACs

E. Forwarding mode of each service set of AC

What is the difference between the center frequency values of two adjacent channels at 2.4 GHz?

A. 20MHz

B. 22MHz

C. 5MHz

In the WLAN network design, the following is the correct design for the cable?

A. The network cable between the AP and the switch should be no more than 100 meters long. In some cases, it should not exceed 80 meters.

B. When calculating the length of the network cable, it is just right to switch from the switch to the AP.

C. Keep away from strong electric and magnetic wires

In the outdoor backhaul scenario, the line of sight is met and there is no interference requirement. When the return distance does not exceed 1km, the uplink bandwidth requirement is 0.5Mbps, and the EIRP is not Restricted, AP external antenna 17dBi_H65 degrees _V7.5 degrees, the maximum number of AT815SN docked by a single AP?

The following is a statement about the combination of the WLAN room subsystem and the existing operator room system. What is wrong?

A. The WLAN signal is not in the same frequency band as the GSM, CDMA, 3G and other signals, and the combiner has a high isolation, so the signal between different frequency bands No interference with each other

B. Existing room division devices (power splitter/coupler/antenna) need to support the 2.4G frequency band of WLAN, otherwise the room division device needs to be replaced.

C. If the operator's signal can meet the coverage requirements, it can usually be satisfied after accessing the WLAN signal.

D. There must be a parallel topology relationship between the APs, and multiple APs are not allowed to be connected in series on one branch.

A. Surveying tools ------ tape measure, range finder

B. Observation record ------ telescope, camera

C. Signal source ------- fat AP

D. Signal scanning ------ laptop

What are the general methods of WLAN planning?

A. Demand collection

B. Product selection

C. Business negotiation

D. Deployment design
