Outdoor bridge return need to focus on the installation of AP at the node, pay attention to the transmission path between nodes.
The following about leaf nodes, sink nodes and transmission paths, which is correct? (Multiple choice)

• A.  If the leaf node needs to be used for coverage, it is necessary to pay attention to the survey contents of the outdoor coverage
• B.  The transmission path is the path between the sites. In the field survey, it is necessary to confirm the distance between the connected nodes. The PMP mode needs to confirm the maximum angle between the links
• C.  sink nodes, leaf nodes cannot be obstructed between obstacles or too far, relay nodes and sink nodes, relay nodes and leaves between the points allowed to block obstacles
• D.  If there are multiple sink nodes need to confirm the location of each sink nodes, each sink nodes also need to confirm the AP installation location, power supply

In WLAN Tester2.0 hot map, tip box shows the following information, according to the information in the figure, which of the following statement is correct?

• A.  The Tip box only displays the the maximum field strength's SINR, PHY Data Rate
• B.  the SINR, PHY Data Rate is 0 that the Tip box does not display
• C.  The Tip box must be placed on the thermal chart 3S and above then it can be displayed
• D.  Tip Displays the signal information around the point
