Assessment/Analysis of Multi-Hop Relay-Enhanced Wimax Networks and the Reliability Concept of Long Term Evolution Advanced (LTE-A) In 4G Wireless Technology
Journal Title: American journal of Engineering Research - Year 2018, Vol 7, Issue 5
Abstract
Modern telecommunication companies have developed or installed high-speed data plan services to convey information in the form of a stream of networks that relay data or information faster than the typical data delivery. Multi-hop relay (MHR) enhanced WiMAX networks are conceivably the most promising Radio Access Technology set up to provide high-speed broadband connectivity to large geographical locations. This research provides an assessment of the challenges of enhanced WiMAX network concepts and its impact in offering reliability within the LTE-Advanced framework. The study identified common physical components, technologies, and wireless standards of enhanced WiMAX networks, establish the effectiveness of Quality of service (QoS) in enhanced WiMAX networks, interpret the challenges of enhanced WiMAX network concepts in LTE-Advanced framework, and analyze the determining factors thataffects enhanced WiMAX network in offering reliability within the LTE-Advanced framework. The study adopted a research survey design byusing a simple random sampling that focused on Collection of data through online questionnaires and analyzing the data to generate specific findings using descriptive statistics, Analysis of Variance (ANOVA), and Principal component analysis. The study found several challenges including; coverage holes due to ‘shadowing’ (r=- 0.642), poor signal to interference and noise ratio (SINR) for the SSs’ with respect to Base Stations, BS (r=919), cost of servicing few Subscribers Stations (SSs) or few users (r=-0.719), reliability problems still persist on inband relaying with respect to out-of-band relaying (r=0.817) and technical and non-technical support services (r=0.854), werefound to be statistically significant in the enhancement of WiMAX networks. The study findings created framework for the implementation of policies on communication technology enhancements that would spearhead infrastructural development towards improvement in multi-hop relay enhanced networks on WiMAX and provide a reliable LTE-Advanced framework.
