PRELIMINARY
Technical Data
3.4 Acoustic Noise
The radio may emit low levels of acoustic noise when operating on low capacity
in LTE.
With the Radio 2217 fan unit, the acoustic noise is ambient temperature
dependent.
The sound pressure level for Radio 2217 without fan and when operating on
low capacity in LTE can be 30 dBA.
The sound pressure levels for Radio 2217 with fan are shown in
Table 6.

The sound pressure level for Radio 2218 without fan and when operating on
low capacity in LTE can be 28 dBA.
3.5 Environmental Characteristics
This section contains operating environment data for the radio.
3.5.1 Operating Environment
The following are the values for the normal operating environment of the radio:
Temperature
(1)
0
40 to +55
C
Solar radiation ≤ 1,120 W/m²
Relative humidity
5–100%
Absolute humidity 0.26–40 g/m
3
Maximum temperature change
1.0
C/min
Maximum wind load at 50 m/s (pole
installed single case)
260 N (front)
(1) Depending on installation scenario, traffic load, and configuration, the product might in the
highest 10
C temperature range, temporary reduce the output power. This depends on the
durations of the high ambient temperature.
