Environmental Capabilities
GSM concepts
The GSM concepts for Normal operation and Extreme operation
conditions as defined in GSM 11.20-12.3.2 are both equal to the
Normal condition as defined and used in this document. This means, all
RF parameters are guaranteed within the Normal condition range as
defined in this document.

41.4.1 General Conditions
The severity of the requirements is in conformity with: IEC 721-3-2
classes 2K4/2B2/2C2/2S2/2M2. and ETS 300 019-1-2 Class 2.3
"PUBLIC transportation".
These requirements are valid for equipped cabinets (excluding batteries).
The values in these conditions are valid for a maximum transport time
of 3 months. The time is measured from the packages are leaving the
shipping store, and includes storing in connection with the transport.
Note: These requirements restrict flight transportation to aircraft
with pressure cabins. As modern aircraft have pressure
cabins, these limitations are expected to be only formal.
41.4.2 Climatic conditions
During transportation the equipment could be exposed to extremes in
temperature and humidity. The equipment shall be in packaged
condition.
