Performance Comparison Between VoLTE and non-VoLTE Voice Calls During Mobility in Commercial Deployment: A Drive Test-Based Analysis
The optimization of network performance is vital for the delivery of services
using standard cellular technologies for mobile communications. Call setup
delay and User Equipment (UE) battery savings significantly influence network
performance. Improving these factors is vital for ensuring optimal service
delivery. In comparison to traditional circuit-switched voice calls, VoLTE
(Voice over LTE) technology offers faster call setup durations and better
battery-saving performance. To validate these claims, a drive test was carried
out using the XCAL drive test tool to collect real-time network parameter
details in VoLTE and non-VoLTE voice calls. The findings highlight the analysis
of real-time network characteristics, such as the call setup delay calculation,
battery-saving performance, and DRX mechanism. The study contributes to the
understanding of network optimization strategies and provides insights for
enhancing the quality of service (QoS) in mobile communication networks.
Examining VoLTE and non-VoLTE operations, this research highlights the
substantial energy savings obtained by VoLTE. Specifically, VoLTE saves
approximately 60.76% of energy before the Service Request and approximately
38.97% of energy after the Service Request. Moreover, VoLTE to VoLTE calls have
a 72.6% faster call setup delay than non-VoLTE-based LTE to LTE calls, because
of fewer signaling messages required. Furthermore, as compared to non-VoLTE to
non-VoLTE calls, VoLTE to non-VoLTE calls offer an 18.6% faster call setup
delay. These results showcase the performance advantages of VoLTE and reinforce
its potential for offering better services in wireless communication networks.Comment: Accepted for presentation and Publication on the IEEE 10th

Atmospheric Influence on the Path Loss at High Frequencies for Deployment of 5G Cellular Communication Networks
Over the past few decades, the development of cellular communication
technology has spanned several generations in order to add sophisticated
features in the updated versions. Moreover, different high-frequency bands are
considered for advanced cellular generations. The presence of updated
generations like 4G and 5G is driven by the rising demand for a greater data
rate and a better experience for end users. However, because 5G-NR operates at
a high frequency and has significant propagation, atmospheric fluctuations like
temperature, humidity, and rain rate might result in poorer signal reception,
and higher path loss effects unlike the prior generation, which employed
frequencies below 6 GHz. This paper makes an attempt to provide a comparative
analysis about the influence of different relative atmospheric conditions on 5G
cellular communication for various operating frequencies in any urban microcell
(UMi) environment maintaining the real outdoor propagation conditions. In
addition, the simulation dataset based on environmental factors has been
validated by the prediction of path loss using multiple regression techniques.
Consequently, this study also aims to address the performance analysis of
regression techniques for stable estimations of path loss at high frequencies
for different atmospheric conditions for 5G mobile generations due to various
possible radio link quality issues and fluctuations in different seasons in
South Asia. Furthermore, in comparison to contemporary studies, the Machine
Learning models have outperformed in predicting the path loss for the four
seasons in South Asian regions.Comment: Accepted for presentation at THE 14th INTERNATIONAL CONFERENCE ON

RADIO ACCESS NETWORK REQUIREMENT FOR NEW DEPLOYMENT OF WIMAX IN DHAKA
Mobile WiMAX is expected to be the next generation radio-interface, complementing WLAN and challenging EVDO/HSPA/LTE. High speed data rate, reduced latency, better Quality of service, and mobility can allow WiMAX to meet the rapidly growing demand of the users. A study of WiMAX Radio Network Planning (RNP) for an urban area like Dhaka city in Bangladesh is presented in this paper in order to help predetermine the radio access infrastructure requirements. A suitable radio planning tool has been used for this purpose. The simulation results of throughput and Carrier to Interference plus Noise Ratio (CINR) are provided
