SATTRANS MicroGSM is a unique hardware and software solution intended for building and operating small GSM networks with one or more base stations. The MicroGSM system is an effective means to provide reliable and affordable mobile communications in areas where no cellular coverage is available.
The MicroGSM system is indispensable for companies and organizations conducting operations
in remote territories. Extracting and construction companies, ship and aircraft operators, military
and security forces, international relief organizations are often in need of reliable mobile
communications for their operational staff in the field. Satellite networks have ubiquitous
coverage areas but are not always suitable for local communication. The MicroGSM solution
provides excellent calling within the area of operations and takes advantage of satellite
networks for hauling long-distance and international calls.
SATTRANS MicroGSM provides the following features:
- GSM-standard voice communication between user terminals within the coverage area
- Ability to access external telephone networks (PSTN, mobile and satellite operators)
- The effective coverage area can be as large as 3,000 km2 (depending on terrain characteristics and the height of the antenna mast)
- The system provides for a GSM standard number of seven (7) simultaneous calls per each base transceiver station (BTS)
- Support of any types of mobile terminals compatible with the system’s GSM frequency range
- Support of any standard subscriber identification module (SIM), which can be either manually pre-programmed in HLR or automatically registered as guest users from other operators (up to 10)
- The maximum number of users in HLR is unlimited, system’s customer billing module allows to log all calls within the cell fro billing purposes
- The system stores logs of all service commands between terminals and the base station for further archiving, analyzing or display
- Small dimensions and light weight, so it can be carried around easily
- Quick and easy setup, operation and dismantling due to the portability of the MicroGSM system.
A standard one-cell MicroGSM solution consists of the following components:
- base transceiver station (BTS)
- BTS controller
- Mobile switching center with HLR/VLR capabilities
These components are assembled in one portable case fit for installation in 19-inch racks. The backside panel has connectors for AC power cable, the service antenna (N-type connector), VGA monitor and PS/2 keyboard and mouse (for initial setup of the system).
Assembly options (available upon customer request):
- water- and dustproof case with backup power source for rough environments
- vehicle installation kit with a 12m mast, a 12dBi omni directional antenna, and a 12VDC power supply.
Upon request a GSM system supporting dozens of base stations and thousands of users can be built and implemented within short time.
