This research paper provides an insight into the comparison between VoLTE and 4G. 4G Wireless Systems or Fourth
generation wireless system is a packet switched wireless system with wide area coverage and high throughput. It is designed to be
cost effective and to provide high spectral efficiency. VoLTE (voice over LTE) supports voice calls over 4G LTE network. With
advanced VoLTE technology, the 4G network now provides high-speed data services, high-quality voice and video calls at
affordable price. This paper first presents the challenges and benefits of both 4G and VoLTE and then compares them with
consideration of different points.
