GSM Mobile Network – mobile network of 2nd generation
Services & Applications

GSM system enables the provision of telecommunications services (Teleservices) and transmission services (Bearer Services).

The telecommunications services may be classified into:

- telephony (including emergency calls and through roaming also in all other networks)
- message services such as SMS (Short Message Services) with the possibility to send a maximum of 160 characters between two points in both directions or with possibility to send the message to all mobile stations in the cell by means of CBS (Cell Broadcast Service) such as traffic or weather reports
- voicemail
- e-mail (service in connection with Internet electronic mail)
- bank services
- information services, etc.

Into the transmission services may be included in particular:

- duplex asynchronous data transmission with transfer rates ranging from 300 to 9 600 bps
- duplex synchronous data transmission with transfer rates ranging from 2400 to 9 600 bps

GSM services are continuously expanded and list of implemented services depends on network operator (provider). At present, these include increasing of the transmission rate up to 14.4 kbps, respectively with the changing of the encoding up to 21.4 kbps.

There are also a variety of services to increase participant comfort. For example, the immediate introduction of accounting services (Hot Billing) allows the use of prepaid cards and their subsequent service charge, and thus creates a group of anonymous users who do not pay flat monthly fees.
