The document discusses Ericsson's response to questions about the inner workings of the GSM mobile system. It provides information on how GSM systems function at a technical level, explaining components like the switching system and protocols that allow mobile devices to connect to the network. The document aims to give insight into the technical details and architecture of GSM networks.

- On 8 October, 2005, a massive earthquake rocked northern Pakistan, killing over 73,000 people and injuring more than 128,000. Around 3.5 million people were left homeless by the 7.6 magnitude quake, which flattened hundreds of thousands of houses, schools, health clinics and shops over a vast and mountainous expanse of land. The Ericsson WIDER system made the different UN organizations able to work together on the same network in a disaster site for the first time in history.
- - GSM systems in container solution prepared for stand alone traffic or intergration into an operators network via radio or satellite link. - WIDER systems in crate solution for IT coordination and integration of several IT user groups into one satellite link. The WIDER also includes opportunity to set up a WLAN. - Satellite antenna systems on stand by. - QuicLink 3G system for stand alone traffic and connectivity to internet is under evaluation for possible use in Ericsson Response missions. Ericsson will install and operate the equipment and where possible include partner operators. In the future other applications will be tried out to develope the Ericsson Response Unit fleet Having an instant radio link capability makes it possible to link different portions of the Ericsson emergency equipment, such as the Oden and Brage GSM systems. MINI-LINK can be used over large distances, provided there is a line of sight between the antennas at each end. This means that telecom services can be implemented quickly over a large area, or to create a connection to a remote disaster area, even if there is no cable network available to link the sites. Instead of having to connect every site directly to a satellite or an existing backbone network, only a single site now requires an external connection. The radio link is not limited to telephone traffic but is equally useful for any type of data transmission. The MINI-LINK can also be used to create a link to non-Ericsson equipment used by other operators, or part of the capacity can be offered to UN organs or relief organizations for their internal needs. The user would in this case only need to hook up by cable to the nearest Ericsson Response site. If need be, the MINI-LINK equipment could even be installed directly at the users’ site, requiring only a suitable mounting base and a power source. MINI-LINK is a market leading product since 40 years, with more than 2 million radio units delivered to users in over 150 countries. The equipment used by Ericsson Response consists of the latest model 15 GHz MINI-LINK TN "hop" with a capacity of 345 Mbits/s. The two sides of the hop each consists of an indoor modem unit, mounted e.g. inside a container, and an outdoor unit mounted on a mast, together with an antenna. The 30 cm antenna size currently selected gives a range of up to 25 km but this can easily be augmented by using a larger antenna. Each hop is pre-configured and the equipment can quickly be made operational on arrival. The MINI-LINK TN is rugged and requires only minimal on-site facilities and maintenance to perform optimally.
- GSM systems GSM systems in container solution prepared for stand alone traffic or integration into an operators network via radio or satellite link. GSM system is used for mobile traffic. In Haiti we had the container "Brage" coming from Brindisi (UN base in Italy) The container GSM system basic configuration consist of 3 sectors i.e. approx 90 simultaneous calls/lines . With additional material delivery the system can expand. - Can be connected to different power supply versions by configuration of the power intake. Connected by micro link, satellite link, cable, etc if integration to other network required. The system can be used as a stand alone network . Size is 7" container The GSM system contains MSC (Mobile Switching Center), BSC (Base Station Controller), HLR (Home Location Register), RBS (Radio Base Station), MINI-LINK, GSM mast Antennas The 12m-high GSM mast is part of a complete, autonomous GSM system with MSC (mobile switching center), BSC (base station controller), HLR (home location register), RBS (radio base station) and MINI-LINK. These container GSM systems are produced in Katrineholm, with all components fitting in a 2.1m container. Even the 12m mast is packed snugly in six 2m tubes inside the container for smoother and quicker Ericsson will install and operate the equipment and where possible include partner operators. In the future other applications will be tried out to developed the Ericsson Response Unit fleet
