Communication Bandwidth for Emerging Networks: Trends and Prospects

Abstract: Bandwidth is one of the essential resources for communication. Due to the emergence of large number of new services in different types of communications and their value added entities, the demand for bandwidth has gone up more than ever before. The Internet and its allied services are one of the main users of the global bandwidth. With this increasing demand, effective usage of the available bandwidth and the discovery of new bands become very important. In this article, we show current bandwidth usages and their utilities in different application domains. We show the present trends of bandwidth used for global communication by taking the international bandwidth of the core networks in to account. We analyzed the bandwidth trends in optical and wireless communication domains. Emerging services such as Internet of Things and their bandwidth provisioning too have been discussed in this article.
