Japanese electric power companies seek to maintain highly reliable telecommunication networks in order to protect, operate, and maintain electric power systems. Hence, such companies operate telecommunication networks that consist of various kinds of network elements, such as microwave radio communication systems, optical fiber communication systems, and communication line carrier networks. Int...

The recent move towards market deregulation and open competition has sparked a wave of serious introspection in the telecommunications service industry. Telecom providers and operators are now required to open up their primary revenue channels to competing industries. In this paper, we examine the service structure of two major global communication networks the Telephone Network and the Interne...

Network design and network synthesis have been the classical optimization problems in telecommunication for a long time. In the recent past, there have been many technological developments such as digitization of information, optical networks, internet, and wireless networks. These developments have led to a series of new optimization problems. This manuscript gives an overview of the developme...

This paper provides an overview of next generation telecommunication networks LTE and WiMAX. They are compared to each other and the current telecommunication networks. It also shows their availability in the world and explains which of these two networks is superior in which case and gives an outlook about their succesors LTE-Advanced and WiMAX release 2.0.

Telecommunication networks are growing very fast. The user’s needs, in regards to new services and applications that have a higher bandwidth requirement, are becoming bigger every day. A telecommunication network requires early design, planning, maintenance, continuous development and updating, as demand increases. In that respect we are forced to incessantly evaluate the telecommunication netw...

As communication networks have evolved towards IP (Internet Protocol) networks, telecommunication operators has expanded its reach to internet multimedia web content services while operating circuit-switch networks in parallel. With the adoption of SOA (Service Oriented Architecture) that enables service capability interfaces to be published and integrated with other service capabilities into n...
