GSM PRI Gateway

pri-1
GSM stands for Global System for Mobile communication. GSM PRI Gateway is a standard European Telecommunication Standards Institute (ETSI) developed to describe protocols for second-generation (2G) digital cellular networks. It replaced the first generation (1G) cellular networks The idea of developing GSM originated from a cell-based mobile radio system at the Bell Laboratories in the early 1970s. GSM is an open, digital cellular radio network in over 200 countries. It uses narrowband time division multiple access (TDMA) technology.GSM PRI Gateway covers almost complete Western Europe and growing in America and Asia. It is not only used for voice calls. Furthermore, it can also be used for data computing and sending text messages. A user can connect his GSM-enabled phone with his laptop to send or receive e-mails, and faxes, browse the internet, check security, etc. GSM was developed using digital technology. It can carry 64 Kbps to 120 Mbps of data rates.
