Mobile telecommunications networks provide the ability to access the internet and use telephony services, where the infrastructure exists. Because of its mobile nature a customer can always connect to the internet, even when not in the comfort of their home, unlike the case with fixed-line services. This paper studies the impact of mobile telecommunications investment on economic growth in South Africa. To test the impact of mobile telecommunications investment on economic growth, the dissertation examines the development of mobile telecommunications infrastructure in South Africa and the relationship between mobile communications infrastructure investment (MCII) on economic growth. It is hypothesised that MCII has a relationship with economic growth. The methodology employed by this study is the autoregressive distributed lags (ARDL) approach with secondary data sourced from the World Bank Group and Global System Mobile Association (GSMA) databases over the period 1994 to 2016. To model the relationship, the study used a neoclassical growth model with proxies for economic growth as gross domestic product (GDP); capital as mobile operator capital expenditure and gross capital formation; and labour as the labour force and the unemployment rate. Results of the study showed that there was a unidirectional Granger causality between GDP and MCII and therefore no bidirectional causal relationship between MCII and GDP. Furthermore, using the ARDL approach found no cointegration between the variables and consequently no long run relationship. Producing the short run model as a VAR (2) model using the Akaike information criteria (AIC) lag selection also resulted in no significant relationship between MCII and GDP. This result has very important implications for policy recommendations to government and for development. Firstly, government should investigate why there is no significant impact of MCII on GDP because this relationship does exist in other markets. From these findings, government can develop and adopt policies which could produce a positive effect of MCII on GDP.

Electronic systems of the future require a very high bandwidth communications infrastructure within the system. This way the massive amount of compute power which will be available can be inter-connected to realize future powerful advanced electronic systems. Today, electronic inter-connects between 3D chip-stacks, as well as intra-connects within 3D chip-stacks are approaching data rates of 100 Gbit/s soon. Hence, the question to be answered is how to efficiently design the communications infrastructure which will be within electronic systems. Within this paper approaches and results for building this infrastructure for future electronics are addressed.

This paper describes problems of eGovernment and proposes way to measure e-Government services. Described is the state of the Czech eGovernment in detail to selected projects and in international comparison. The description shows that the development is still ongoing, but in a much slower pace than in the electronically advanced countries. Main identified problem is inconsequent strategic management and resortism, which is constraining deployment of cross-resort projects. Based on the description of the current situation and on the international experiences, author offers specific recommendations to future development of the electronization of public administration in the Czech Republic. In response on management problems is in this paper proposed and tested methodology for measuring the effectiveness of e-Government services. This methodology is an objective procedure of measuring the effectiveness of e-services which is providing feedback for service providers. Testing of methodology evaluates three services from taxation agenda and highlights their weaknesses, including the proposal of corrective solutions.
