質問 12

If the Fit AP fails to register successfully during the Layer 2 registration process, the following information can be obtained by debug lwapp on the WLC side:
*Oct 17 14:38:05:117 2008 5002 LWPS/7/Event : Discovery request message received from AP with WA2220E-AG Model and Serial-ID 210235A22WC07C000300
*Oct 17 14:38:05:127 2008 5002 LWPS/7/Error : AP not found for Serial-ID 210235A22WC07C000300
*Oct 17 14:38:05:137 2008 5002 LWPS/7/Error : Discovery request is dropped due to Processing failed

質問 13

Which of the following is the correct description of the room division system
Which of the following is the correct description of the principle of indoor distribution system combining is _______.

（A）In the acceptance test stage, the comparison before and after combining should be carried out from the aspects of system coverage field strength, call quality, handover, call drop, and the influence of the technical parameters of the source base station.

（B）If the system power is insufficient, it is necessary to replace the original transmission feeder of the system or add a power amplifier.

（C）According to the coverage and the installation position of the combined access point, it is necessary to make a reasonable calculation of the power of the two networks to determine the installation position of some active devices.

（D）The quality of the combined access point selection directly affects the system effect of the two networks in one. Generally speaking, it is mainly selected on the branch of the GSM/CDMA indoor distribution system, one will not affect the power distribution of the GSM/CDMA network backbone, and the other can reduce the loss of the WLAN network in feeder transmission and ensure that the

質問 14

Which of the radio link handover control parameters is correct?

（A）Link Hold RSSI : The minimum signal strength required to establish and maintain a link

（B）Link Switch Margin: The signal threshold for switching the backup link to the primary link. When the signal difference between the RSS I of the backup link and the RSS I of the primary link is greater than the Link Switch Margin value, the backup link switches to main link

（C）Link Hold Time: In order to prevent frequent switching of the primary link, when the backup link switches to the primary link, the shortest duration of the primary link is maintained.

（D）Link-maximum-number : The number of MESH links established between the on-board MR and the trackside, including the main link and the backup link

（E）Link Saturation RSSI: When the signal strength of the opposite end exceeds this threshold, it may cause signal reception saturation, resulting in failure of demodulation and link failure. At this time, link switching will be performed immediately
