3.3 Reference sensitivity
3.3.1 GSM
Sensitivity on 50 Ohm
The sensitivity is according to the GSM specification for the class 4 portable terminal;
The standard ETSI regulation para 6 fix a limit of –102dBm.
The goal limit is –104 dBm for an Rx Quality < 0.2 – 0.4%.

The antenna for the GSM band is ALLGON 3576.2
3.4.2 Globalstar
The antenna for the satellite Globalstar band is composed of more parts and is assembled
on the telephone in way that can rotate on 4 positions.
The satellite antenna in its rotating stalk contains an LNA for the Rx section, the receiving
part Rx and the transmitting part Tx.
An optical sensor assembled on the body of the telephone under the antenna rotor, activates the satellite transmission when the antenna is rotated in the positions 1, 2 and 3. In
the intermediary positions the transmitter of the satellite section is always disabled.
In the position 0 the telephone works only on the GSM band.
The rotation of the antenna is prevented over the position 3.
