In the backhaul scenario where the AP6510DN is connected to the AT815SN in point-topoint, the return distance is about 100m. The six AT815SNs are distributed in a length of 60 meters and wide. Within 60 meters, the equipment is installed at the same height and has a line of sight.
When the upstream bandwidth requires 10 Mbps and there is no EIRP limit, which of the following antennas can be selected?

A.

5G_19dBi_H15 degrees _V15 degrees

B.

5G_17dBi_H65 degrees _V7.5 degrees

C.

5G_16dBi_H100 degrees _V5.5 degrees

D.

5G_28dBi_H5 degrees _V5 degrees

The following statement about the connection of the device is wrong?

A.

The joints on the AP/power splitter/coupler/combiner/antenna are generally N-type male heads, and the two ends of the feeder are generally N-type female heads, and the two are connected to each other.

B.

Under normal circumstances, the indoor system or the longer distance (greater than 50 meters) uses 7/8 lines, and the tributary or short-distance transmission uses 1/2 feeders.

C.

1/2 super soft feeder is very thin and flexible. It is generally used in the case where the gap is small or the turning angle is large.

D.

When the actual project calculates the feeder, the short feeder can directly calculate the number of standard feeders. After the long feeder needs to confirm the routing path, reserve 10%. ~20% feeder length

What is the encryption technology used by CAPWAP?

A.

WEP

B.

TKIP

C.

CCMP

D.

DTLS

What are the advantages of PoE switches compared to PoE power injectors?
