Comparison: 3G Wireless Networks with 4G Wireless Networks Technology Wise

Abstract

Opportunities and challenges compel us to throw light on the differences between the two 3G and 4G networks. This task is being done in order to list out the drawbacks and merits of these 3G and 4G evolutions of the networks and further to implement R&D research to bring out their sparks in this modern era. If we look into 4G, objective of 4 th generation is to enhance specifications for a new radio-access technology for higher data rates, low latency and greater spectral efficiency so 4G (also known as LTE-Advanced) is therefore not a new technology; it is actually an evolutionary step in the continuing development of LTE. The differences of 3G and 4G are done on the following Index terms: Background difference, definitions, technologies progress, speed/ rate of transmission, switching technologies used, network, band width, design specification, QoS, service and billing, features and capabilities.
