High-end commercial buildings, airports, large venues, large shopping malls, high-end residential communities and other large traffic and VIP scenarios are suitable for co-deployment of MIMO solutions. What are the advantages of this solution? (Multiple choice)

A.

High capacity

B.

Can fully reflect the MIMO uplink and downlink capacity gain

C.

low cost

D.

project Low difficulty

For the same-frequency switching scenario, which of the following parameters has little effect on the handover?

Up and Downmcs

B.

RSRP&RSRQ&RSSI&SINR

C.

What are the principles that need to be followed when planning LTE neighboring cells? (Multiple choice)

A.

Neighborhoods that are directly adjacent to the geographic location are generally regarded as neighboring cells

B.

For dense urban areas and ordinary urban areas, due to the relatively close distance between stations (0.3-1.0 km), neighbouring areas should do more

C.

Because there are no sequential I and possible questions in LTE neighboring cells, and the detection period is very short, it is only necessary to consider not missing neighboring cells, and it is not necessary to sort neighboring cells strictly according to signal strength.

D.

Turn on ANR to completely replace the neighborhood planning of the initial network

Regarding the over-zone, overlapping coverage control, which of the following statements is wrong?

A.

Station height control: strictly control the station height to avoid over-zone interference

B.

Station spacing control: strictly avoid overlapping coverage sites within 100m

C.

Topological structure planning: the site distribution is as uniform as possible

D.

The angle of the sector in the station should be kept as close as possible to 60 degrees, direct sparring between stations can enhance coverage

Which of the following events is the basis for LTE synchronous frequency switching?

A.

A1

B.

A2

C.

A3

D.

B1

What are the evaluation methods for overlapping coverage issues? (Multiple choice)

A.

The number of cells with RSRP>-100dBm is greater than or equal to 2.

B.

The number of cells with RSRP>-100dBm is greater than or equal to 3.

C.

RSRP of the strongest cell-RSRP of the 3rd strongest (or 4th strongest) cell<6dBo

D.

RSRP of the strongest cell-RSRP of the 3rd strongest (or 4th strongest) cell<3dBo
