Location & Environment
2.3
In addition to network planning, when determining where to place the eNB you need to
consider factors such as climate, hydrology, geology, the possibility of earthquakes,
reliable electric power, and transportation access. Avoid locating the eNB in areas where
there may be extreme temperatures, harmful gases, unstable voltages, volatile
vibrations, loud noises, flames, explosives, or electromagnetic interference (e.g., large
radar stations, transformer substations). Avoid areas prone to impounded water, soaking,
leakage, or condensation.
Table 2-2 provides typical environmental specifications for this eNB.
