Enable the wireless user speed limit function on the SSID "H3C" of the Fat AP, the configuration is as shown in the figure.

Based on the above configuration, which of the following statements are correct?

• A. If the number of users currently connected to this Fat AP is 10, the bandwidth per user cannot exceed 20000/10=2000Kbps.
• B. If the number of users currently connected to this Fat AP is 10, and 5 of them have no traffic, the bandwidth per user cannot exceed 20000/5=4000Kbps.
• C. If the number of users currently connected to this Fat AP is 10, the maximum bandwidth per user cannot exceed 20000Kbps.
• D. The wireless user speed limit function of Fat AP is divided into static speed limit and dynamic speed limit. The above configuration realizes dynamic speed limit.

Which of the following is incorrect about WLAN engineering optimization

• A. The five-category wiring distance between AP and POE switch should be controlled within 150m
• B. The network cable on the AP should have a corresponding label to identify the information such as the number and location of the AP
• C. The surrounding of the AP should try to avoid the electric egg wave interference devices, such as the constant trace furnace, bluetooth equipment, etc.
• D. Select antenna type according to different coverage scenarios

For area coverage planning with large radius and few concurrent users, the correct statement is

• A. 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.
• B. 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.
• C. 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
• D. 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

The correct description of an area with a small radius and few concurrent users is:

• A. Generally speaking, one AP can meet the requirements of wireless signal coverage and the number of users in such areas. The key is to choose the appropriate AP installation location and installation method.
• B. Generally, the radius of such area is less than 60m, and there are not many users accessing it.
• C. When planning the coverage of residential households, the AP placement location should be selected reasonably to take into account the wireless signal coverage of each room.
• D. Generally speaking, small meeting rooms, bars, cafes, residential homes, etc. belong to this type of area.

Contents and concerns of survey decision-making include ?

• A. Approve the total number of APs required for coverage, and add a 5%~10% margin
• B. Determine the antenna type corresponding to the AP (built-in antenna, ceiling antenna, outdoor antenna, etc.)
• C. Calculate the number of access switch ports connected to the AP, and make the number ratio according to the actual situation. At the same time, it needs to be considered in combination with the power supply mode (when using POE/POE+ mode, the output power of the switch).
• D. Determine the AP selection mode (11agn, 11ac, single and dual frequency) and the exact installation position
