What are the principles to be followed when planning LTE neighboring areas? (Multiple choice)
A . A geographically directly adjacent cell is generally used as a neighboring area.
B . 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
C . Because there is no prioritization problem in the neighboring area of LTE, and the detection period is very short, it is only necessary to consider not missing the neighboring area, and it is not necessary to sort the neighboring cells strictly according to the signal strength.
D . Turn on ANR to completely replace the neighboring area plan of the initial network.
