D.2 Environmental requirements for the MSs

3GPP45.005GSM/EDGE Radio transmission and receptionTS

The requirements in this clause apply to all types of MSs.

D.2.1 Temperature (GSM 400, GSM 900, ER-GSM 900 and DCS 1 800)

The MS shall fulfil all the requirements in the full temperature range of:

+15C ‑ +35C for normal conditions (with relative humidity of 25 % to 75 %);

‑10C ‑ +55C for DCS 1 800 MS and small MS units extreme conditions
(see IEC publications 68‑2‑1 and 68‑2‑2);

‑20C ‑ +55C for other units extreme conditions (see IEC publications 68‑2‑1 and 68‑2‑2).

Outside this temperature range the MS, if powered on, shall not make ineffective use of the radio frequency spectrum. In no case shall the MS exceed the transmitted levels as defined in 3GPP TS 45.005 for extreme operation.

D.2.1.1 Environmental Conditions (PCS 1 900, GSM 850 and GSM 700)

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:

MS Temperature Range:

-10°C to +55°C

D.2.2 Voltage

The MS shall fulfil all the requirements in the full voltage range, i.e. the voltage range between the extreme voltages.

The manufacturer shall declare the lower and higher extreme voltages and the approximate shut‑down voltage. For the equipment that can be operated from one or more of the power sources listed below, the lower extreme voltage shall not be higher, and the higher extreme voltage shall not be lower than that specified below.

Power source	Lower extreme	Higher extreme	Normal cond.
	voltage	voltage	voltage
AC mains	0,9 * nominal	1,1 * nominal	nominal
Regulated lead acid battery	0,9 * nominal	1,3 * nominal	1,1 * nominal
Non regulated batteries:
Leclanché	0,85 * nominal	nominal	nominal
lithium	0,95 * nominal	1,1 * nominal	1,1 * nominal
mercury/nickel cadmium	0,9 * nominal	nominal	nominal

Outside this voltage range the MS, if powered on, shall not make ineffective use of the radio frequency spectrum. In no case shall the MS exceed the transmitted levels as defined in 3GPP TS 45.005 for extreme operation. In particular, the MS shall inhibit all RF transmissions when the power supply voltage is below the manufacturer declared shut‑down voltage.

D.2.3 Vibration (GSM 400, GSM 900, ER-GSM 900 and DCS 1 800)

The MS shall fulfil all the requirements when vibrated at the following frequency/amplitudes:

Frequency ASD (Acceleration Spectral Density) random vibration

5 Hz to 20 Hz 0,96 m2/s3

20 Hz to 500 Hz 0,96 m2/s3 at 20 Hz, thereafter ‑3 dB/Octave

(see IEC publication 68‑2‑36)

Outside the specified frequency range the MS, if powered on, shall not make ineffective use of the radio frequency spectrum. In no case shall the MS exceed the transmitted levels as defined in 3GPP TS 45.005 for extreme operation.

D.2.3.1 Vibration (PCS 1 900, GSM 850 and GSM 700)

10 – 100 Hz: 3 m2/s3 (0.0132 g2/Hz)

100 – 500 Hz: -3dB/Octave
