Abstract
This study focuses on heterogeneous services and communication technologies for retrieving and sending information in Malaysian Higher Educational Institutes. It intends to investigate pattern and significant level of various services implementation, convergence of communication technologies, bandwidth capacity for Internet (WAN)/LAN and Quality of Service (QoS). It is designed to determine which communication technologies, services, bandwidth capacity and QoS will achieve the highest level acceptance in Malaysian Higher Educational Institutes. Heterogeneous environment can also generate mobility approaches. A survey method is used to collect data from respondents (System Network Administrator) in Malaysian Higher Educational Institutes. Statistical Analysis using t-test shows that implementation of high speed bandwidth for Internet (WAN) achieved significant level. Frequency test are used to analyze the various services implementation via convergence of communication technologies in heterogeneous environment for retrieving information. The results did not show any significant difference on implementation of various services over convergence of communication technologies and it also shows decreasing of graph in exponential pattern. The most apparent finding of this study is that various services implementation in Higher Educational Institutes can affect convergence of communication technologies usage in accessing information over heterogeneous network environment. From the survey results, it confirms that Malaysia Higher Educational Institutes have not achieved a maximum level of various services implementation via convergence of communication technologies in heterogeneous network environment and QoS implementation. Therefore, low convergence of communication technologies can also produce a low mobility and ubiquitous computing environment in Malaysian Higher Educational Institutes. Recommendation based on the finding for future work is to develop heterogeneous model environment for evaluating convergence of communication technologies and services performance in Higher Educational Institutes.
