D.3 Environmental requirements for the BSS equipment

05.053GPPRadio transmission and receptionTS

This clause applies to both GSM 400, GSM 900 and DCS 1 800 BSS equipment.

The BSS equipment shall fulfil all the requirements in the full range of environmental conditions for the relevant environmental class from the relevant ETSs listed below:

EN 300 019‑1‑3: Equipment Engineering (EE); Environmental conditions and environmental tests for telecommunications equipment, Part 1‑3: Classification of environmental conditions, Stationary use at weather protected locations.

EN 300 019‑1‑4: Equipment Engineering (EE); Environmental conditions and environmental tests for telecommunications equipment, Part 1‑4: Classification of environmental conditions, Stationary use at non‑weather protected locations.

The operator can specify the range of environmental conditions according to his needs.

Outside the specified range for any of the environmental conditions, the BTS shall not make ineffective use of the radio frequency spectrum. In no case shall the BTS exceed the transmitted levels as defined in 3GPP TS 05.05 for extreme operation.

D.3.1 Environmental requirements for the BSS equipment

The following clause applies to the GSM 850, PCS 1 900, MXM 850, MXM 1900 BSS.

Normal environmental conditions are defined as any combination of the following:

Temperature Range

+15°C to +35°C

Relative Humidity

35% to 75%

Air Pressure

86 kPa to 106 kPa

Extreme operating temperature ranges depend on the specific manufacturer and application, but typical ranges are as follows:

BSS Indoor Temperature Range:

-5°C to +50°C

BSS Outdoor Temperature Range:

-40°C to +50°C
