The GSM/GPRS technology quickly conquers the professional telemetry applications market and gets the advantage over the radio modem solutions being commonly used up to now. The wide areas of applications include an environment protection, water-sewage systems, agriculture, forestry, power and gas industries, utilities, remote reading of media consumption and object security. The basic benefits of wireless GSM/GPRS systems usage in an remote monitoring and control are low costs, short time of implementation, unlimited distance between the objects, insensibility to lay of the land and natural obstacles (e.g., forests or high buildings), lack of complicated antenna systems and capability to announce the alarm events directly to the mobile phones of responsible persons. The GPRS technology provides direct and secure access to the information using mobile devices (phones, PDAs and computers). Additionally, there is no bottleneck effect in the central station in case of complex telemetry systems. An HDSPA router used in the central station normally provides up to 1.8 Mbit/s throughput, and even up to 10 Mbit/s with the fixed link to the network operator. The event-driven transmission (when the object itself is sending data under defined circumstances) allows fast and simultaneous sending the information about state changes of the arbitrary located objects to the central system, even in the case of very large installations with hundreds of monitoring points.
