Abstract/Summary:
he International Telecommunications Union stated that 4.53 billion people use cellular telephones. Cell phones commonly drop calls. The purpose of the research was to investigate a new form of wireless transmission that has been termed manifold pathway network wireless systems. The method aims to reduce one of the primary reasons for dropped calls, that of shadow fading. The manifold concept uses multiple base stations to maintain calls. The present method uses one base station at a time. The study of shadow fading and fading phenomenon provided background knowledge. The research question was related to the difference in average call drops between manifold systems versus standard wireless networks. A quantitative design using 80 computer simulation experiments was guided by a Markov chain model as a theoretical framework. The mean number of call drops for a manifold system with nesting layer of two was 4.6 versus 33.6 for a normal wireless network. The t test showed a significant result for call drops, t(9)=16.07, p <0.00001, with higher call drops in a normal wireless network. Simulation results were reincorporated into the Markov chain model. The manifold concept could generate technological progress by reducing the number of dropped calls. Social impacts include the potential to save lives by retaining some of the 531,333 emergency calls that drop worldwide. Another major social impact is the reduction of subscriber churn that costs the wireless industry...
