GSM stands for Global System for Mobile communication.
<a href="https://www.asfera.in/products/gsm-pri-gateway.html">PRI Gateway</a>
is a standard developed by European Telecommunication Standards Institute
(ETSI) to describe protocols for second generation (2G) digital 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
operating in over 200 countries worldwide. It uses narrowband time division multiple access
(TDMA) technology. GSM PRI Gateway covers almost complete Western Europe
and growing in America and Asia.
