With growing demands for fast provision of new and complex services, imposed by life and business dynamic in general, service providers are forced to adopt open technologies and advanced business models in their solutions. These enable a fast response to market demands and maximum utilization of the network. A big challenge for operators today is how to deliver broadband services in rural areas...

WiMAX and LTE are the telecommunication technology standards. WiMAX and LTE both offer high data rate. Both are used to provide VOIP, online gaming, video conferencing, streaming media services to the users. In this paper we have done numerical analysis of WiMAX and LTE network in the form of maximum number of users supportable and minimum demand to all the users in a particular area based on d...

In this paper we investigate multi-service load balancing mechanisms in an overlay heterogeneous WiMAX/WLAN network through vertical handover. Considering the service characteristics of the overlay heterogeneous network together with the service requirements of different applications, all streaming applications are served in WiMAX while elastic applications are distributed to WiMAX and WLAN. Tw...

In this paper, a novel multi-frequency microstrip antenna with complementary ring slot resonator (CRSR) structure that satisfies Bluetooth, worldwide interoperability for microwave access (WiMAX), and wireless local area network (WLAN) applications is proposed. The conventional consists of circular patch at resonance frequency band 2.5 GHz. By loading two CRSR the radiating element, three opera...

Wimax is a standard based wireless technology that provides high throughput broadband connection over long distance. It can offer low cost high speed and long range communications for applications. In wimax relay networks the relay stations are used to improve the transmission quality. Bandwidth allocation is the process of assigning bandwidth to users and applications. The comparative analysis...

A study on the design of heterogeneous transceivers using the software radio approach is presented. The objective of the study is to extend the research on software radio towards the design of multi-protocol transceivers which can communicate between two or more heterogeneous wireless access technologies. A critical overview of some of the current multiprotocol software radio devices is present...

We investigate the performance and coexistence techniques for worldwide interoperability for microwave access (WiMAX) delivered from high altitude platforms (HAPs) and terrestrial systems in shared 3.5 GHz frequency bands. The paper shows that it is possible to provide WiMAX services from individual HAP systems. The coexistence performance is evaluated by appropriate choice of parameters, which...

Voice over IP (VoIP) applications such as Skype, Google Talk, and FaceTime are promising technologies for providing low cost voice calls to customers over the existing data networks. Wireless networks such as Wi-Fi and WiMAX focus on delivering Quality of Service (QoS) for VoIP applications. However, there are numerous aspects that affect quality of voice connections over wireless networks. In ...

This work aims the implementation and analysis of an environment formed by WiMAX and MetroEthernet networks. WiMAX offers unwired broadband access with high capacity of data transmission for dispersed areas. This network allows the interconnection of MetroEthernet networks with connection up to 10Gbps. The study herein presented deals with a proposal of an end-to-end Quality of Service (QoS sui...
