For the following LTE neighborhood planning, which description is correct?

The directly adjacent cell geographically is generally used as a neighboring area.

For dense urban areas and ordinary urban areas, due to the relatively short distance between stations (0.3~1.0 km), neighboring areas should do more

Because there is no sequence problem in the neighboring area of LTE, and the detection period is very short, it is only necessary to consider not missing the neighboring cells without needing to sort the neighboring cells strictly according to the signal strength.

ANR function can completely replace the neighboring area planning of the initial network
