H12-322 Exam Dumps - Huawei HCIP-WLAN Questions and Answers

This network diagram is the data forwarding mode of the datagram. All data packets in the figure are not AC.

All management messages must be forwarded through the tunnel.

All signaling packets can be forwarded directly without forwarding through the tunnel.

The wireless user service data in this network needs to be converted to 802.3 and 802.11 packets on the AC, and then through the upstream aggregation switch.

Forwarding

The combiner can synthesize multiple input signals and output them, and then separate and filter the mixed signals.

The splitter can divide one signal equally into multiple outputs

The coupler is a power splitter whose output power is not equally divided. It takes the required signal energy from the main line to the far-end antenna, and allocates more.

Signal energy to the proximal antenna

The WLAN room sub-network generally uses a microstrip power splitter, which has low power and low cost compared to the cavity power splitter.

The office surveys the main load-bearing columns and partitions to cover the impact. If it is an overall suspended ceiling, the AP should be considered as close to the maintenance port, if it is metal

Ceiling, you can choose to place the AP under the ceiling or wall mount

If the wall of the school classroom is made of reinforced concrete, the signal attenuation is large. It is best to measure the attenuation when surveying. The teaching building should pay attention to the weak electricity room.

Set

The ward inspection scene has high requirements for coverage field strength, roaming effect, and bandwidth requirements. At the same time, it is necessary to pay attention to the interference or disallow of medical equipment.

Area with Wi-Fi signal

The stadium has a complicated environment and difficult wiring. Therefore, the weak house and the wiring should be confirmed with the property. If the distance is too far, it may be considered.

Adding an external switch, the survey should focus on mutual interference and installation methods between APs.

Final signal field strength = antenna gain - transmission distance attenuation value - obstacle signal attenuation

Final signal field strength = AP transmit power + antenna gain - transmission distance attenuation value - obstacle signal attenuation

Final signal field strength = AP transmit power - Transmission distance attenuation value - Obstacle signal attenuation

Final signal field strength = AP transmit power + antenna gain + transmission distance attenuation value - obstacle signal attenuation

Cannot export multiple paths at the same time

Only one path packet can be imported at a time

Indoor and outdoor paths support mutual guidance

The path only supports importing nodes whose drawings are not larger than the original drawing.
