質問 37
When using a WLAN dual-frequency combiner to expand the capacity of an indoor distributed system, which of the following statements is correct? (Multiple choice)
- A. 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.
- B. The WLAN combined channel expansion solution can increase the overall WLAN system capacity by combining two APs using different channels.
- C. 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.
- 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.
正解: A,B,C
