In order to ensure coverage of a larger area, the antenna should be as high as possible

In order to ensure that there is no black under the tower, the antenna should be as low as possible.

Directional antenna hanging height is not recommended more than 12m

The network card must be loaded before each survey.

After opening the tool, you only need to load the network card once.

After entering the tool for the first time, the network card must be loaded when starting the survey.

After opening the tool to load the network card, the second network card will be loaded automatically, but there is an interval between them.

Tip shows the signal information around the point

Tip box must be placed on the heat map for 3S and above to display

The SINR and PHY Data Rate that are not displayed in the Tip box are 0.

Tip box only shows the SINR and PHY Data Rate of the maximum field strength value.

The management VLAN is responsible for transmitting packets forwarded through the CAPWAP tunnel, so the management VLAN must be VLAN 1.

When using tunnel forwarding, the management VLAN and service VLAN cannot be the same VLAN.

When tunnel forwarding is used, the management VLAN and service VLAN can be the same VLAN.

When deploying authentication-based user VLANs, use in conjunction with user group authorization technology

Office coverage, high concurrency, medium density

Concert hall coverage, low concurrency, high density

ward inspection, no bandwidth requirements, need good coverage

Hotel rooms are covered, the rooms are small and dense, and there are certain requirements for coverage area and field strength.

The STA listens to each channel beacon and finds that AP2 satisfies the roaming condition and sends a probe request to AP2.

AP2 responds by sending a response on channel 6 after receiving the request in channel 6 (the channel used by AP2)

The STA sends the 802.11 disassociation information to the AP1 through the channel 6 (the channel used by the AP2), and the association between the user and the AP1 is released.

The STA sends an association request to AP2 through channel 6, and AP2 responds with the association response to establish an association between the user and AP2.

False

The WLAN and CATV signals are mixed by the signal combiner and input to the existing CATV cable, and transmitted to the CATV coaxial shielded cable.

In the room, finally separate the signals through the splitter panel to achieve indoor wireless network coverage and TV signal transmission.

The overall construction of WoC does not need to be changed too much, the construction impact is negligible, and the wireless coverage is better. It is excellent in wireless system transformation projects.

Obvious

Signal combiner and WoC panel, need to be customized separately from the partner

At present, the cable commonly used by CATV is SY(W) V75-5 coaxial cable, which is specially produced for cable TV. The transmission frequency of 2.4G is very small, so the distance from AP to terminal panel can be longer, but it is recommended not to exceed 500 meters

Combine multiple input signals into one output, and then split the mixed signal in the opposite direction.

Average one signal into multiple outputs

Take the required signal energy from the main line to the near-end antenna and allocate more signal energy to the far-end antenna

The network is divided into access layer, distribution layer and core layer.

AP is connected to the access layer switch. It is recommended to use a PoE switch.

AC can be implemented using the built-in AC card of the core switch.

At the access layer, you can use the side-mounted CA to implement wireless centralized control.

The Fresnel zone of the radio beam is an ellipsoidal region that surrounds the visible line of sight directly.

The antenna installation position should ensure that the two nodes of the link are visible, and try to ensure that there is no obstruction in the Fresnel zone.

Two nodes of the site link are visible, and the Fresnel zone boundary is blocked, which will not affect the link transmission effect.

The distance between the stations is 2 kilometers, and the radius of the Fresnel area is about 6 meters.
