We all use mobiles daily, we communicate with a lot of our friends. How does that work exactly?? What is the difference between GSM and CDMA. The layman won’t try to understands the differences between them and the technology which is existing.
But let’s see on what is GSM in this post!!
What is GSM?
GSM stands for Global System for Mobile communication originally Groupe Spécial Mobile. This standard was developed by European Telecommunication Standards Institute(ETSI).
GSM standard was developed as a replacement of the 1G(1st Generation) analog cellular networks.
ETSI describes the GSM standard as the 2G technology. The 2G technology uses a digital, circuit-switched network optimized for full duplex voice telephony.
This expanded over time to include data communications, first by circuit-switched transport, then by packet data transport via GPRS (General Packet Radio Services) and EDGE (Enhanced Data rates for GSM Evolution or EGPRS).
2G technology was first deployed in Finland in July 1991. And as of 2014 it has become the standard over 90% market share in over 290 countries and territories.
Subsequently, 3G and 4G technologies have evolved. Currently 5G technology is under research.
Stay tuned for more explanations on 3G, 4G and 5G technologies!!!
Something excited happens every moment!! So, stay excited!!!
