Wireless network capacity optimization needs to consider the service types and user models of customers in different scenarios, and provide customers with capacity optimization suggestions based on network construction standards. When a customer has 300 users accessing the existing network, the concurrency rate is 40%, the average bandwidth of a single user is 16Mbps, and the terminal bandwidth of the currently selected AP is 16 Tlbpsi, the number of concurrent terminals is 15, then in order to meet the capacity requirements, () APs need to be deployed in the area.

Drag and Drop Question
When designing the network plan for an outdoor parking lot, there may be two situations as shown in the following figure (with buildings and without buildings). Please match the antenna type, installation method and AP deployment method recommended by the following network plan with the two situations.

In a WLAN network, there is a Wi-Fi 6 AP with 12 antennas. How many spatial streams can the AP support at most?

Use terminal dialing test tools to evaluate the quality of customer networks. After the test is completed, export the test report. The test results show that the Internet uplink performance and Internet downlink performance test results are poor. Internet uplink performance: average 5Mbps, failure rate 100%; Internet downlink performance: average 21Mlbps, failure rate 100%. In response to the above problems, which of the following optimization and troubleshooting measures are recommended for customers? (Multiple choice)
