Installation Guide

3. Avoid to install near high-power wireless transmitter stations, such as radar stations,
television stations, etc. If the gNB must be installed in such locations, you should
check whether there is mutual interference, and take measures to prevent it.
4. Avoid to install on mountains. The mountain interference range is large, therefor the
frequency reuse will be affected. Install gNB on high mountains in rural areas is
often not good for the coverage of towns and villages in small basins.
5. Avoid to install in the forest. If the gNB must be installed in such locations, the height
of the gNB must be higher than the treetop.
6. It is strictly prohibited to install the gNB in the mining area and places where is easy
to be submerged by flood and landslide
7. In urban area, for the macro gNB, the site should be selected that is higher than the
average height of buildings but lower than the highest building. For the micro gNB,
the site should be selected that is lower than the average height of buildings and the
surrounding buildings are well shielded.
8. In urban area, the gNB should avoid obstructions caused by tall buildings near the
front of the antenna or the reflection interferes the same frequency gNBs behind it.
9. Avoid selecting sites where new buildings may affect coverage or there are
co-frequency interference.
10. As far as possible, the site of gNBs of the two communication network systems
should be co-located or close.
