Mobile GSM Infrastructure over Satellite
Mobile GSM Infrastructure over Satellite ( MOGIS , GSM over satellite ) from Siemens AG enables cell phones to be used in remote areas that are not served by radio masts .
MOGIS is a mobile GSM solution based on the standard cellular technology from Nokia Solutions and Networks , expanded to include a compressive, bandwidth-saving transmission via satellite.
The Airbus company has IP-based pico base stations behind the aircraft ceiling paneling, which connect mobile devices to the GSM cellular network with the help of satellite technology. For this purpose, SDE developed hardware and software that suppress direct communication between the base station and mobile device, so that radio traffic from the aircraft goes exclusively via satellites so as not to interfere with the aircraft electronics.
MOGIS is completely IP-based and has an Opex reduction of 86%, which allows seven simultaneous telephone calls at 64 kbit / s. It can be deactivated externally at any time and activated automatically, for example at a certain GPS position . Voice and signaling data are also compressed using this software in order to minimize the satellite bandwidth and to adapt the communication protocols between the GSM network and the satellites.
MOGIS is mainly used in airplanes, trains and ships and supports numerous satellite systems, such as Inmarsat , DVB-RCS , VSAT , etc. a.
