In the evolution of cellular wireless technology by European Telecommunication Standardization Institute(ETSI) came out with enhanced TDMA based Global System for Mobile(GSM) Technology that was widely adopted by almost 90% of the world except North America that were already on CDMA technology for cellular wireless communication.This technology was developed for a full scale roaming and interoperability across globe. While world is moving toward 3G, 4G, LTE, IMS and 5G, GSM is still co-existing in almost everywhere in the world, because  transition to these new technology requires huge capital expenditure.

In this course we will study about the architecture of GSM wireless technology with focus on fundamentals and easy learning through mapping the architectural concept with OSI and internet architecture. The course builds up the understanding from basic of telephony and slowly moving toward most complex IP and SS7 architecture of network that co-exist today.

Apart from architecture and call flow, the management of network and business application system has been explained to complete the 360 degree view of GSM networks. 

This course will help you to explore the service provider environment and how they manage the business of air-time selling. You will be better equipped with knowledge to intelligently ask questions and engage in the discussion among telecommunication eco-system partners and service providers.
