Environmental Capabilities

The purpose of this chapter is to specify the environmental capabilities
for RBS 2301 and RBS 2302.
41.1 Scope
This chapter describes the environmental capabilities for the indoor and
outdoor temperature non-controlled operation conditions. Subjects
included are: Climatic, Biological, and Chemically active substances;
Mechanically active substances, and Mechanical conditions.
The capabilities cover the base station excluding installation and
adjacent parts as antenna and earth connectors.
Note:
41.2 Terminology
Definition of concepts:
Normal operation conditions
Environmental conditions where all units shall be able to function as
specified.
Safe function
Environmental stress above the limits for normal operation where all
units shall continue to function during the stress, but performance or
capacity may be reduced.
Reduction of performance or capacity shall be documented as typical
value.
When the environmental stress has dropped to normal operation
conditions, function as specified shall automatically be achieved.
Safe function refers to an operation period of not more than 72
consecutive hours, and a total of not more than 15 days in one year.
Non-destruction
Environmental stress above the limits for safe function during which no
function is guaranteed and performance may degrade in an unspecified
manner.
When the environmental stress has dropped to normal operation
conditions, no manual intervention (on site) is needed to restore full
performance of the RBS.
Non-destruction refers to an operation period of not more than 96
consecutive hours, and a total of not more than 5.5 days in a 3 years
period.
