Due to the integration of different wireless applications at different bands on a single device, multi-band microstrip patch antenna is the best solution keeping the overall size of the device small. In the present work, a metamaterial-inspired antenna is proposed for WiMAX/WLAN applications. Design studies, parametric analysis, simulation results along with measurements for a L-shape slotted g...

The standardization of worldwide interoperability for microwave access (WiMAX) represents an opportunity for a radical shift in viewing the Internet and its access systems. Considering the current constellation of the Internet service providers (ISPs), WiMAX can both improve its presence (by offering broadband connectivity where previously unavailable) and trim down its authority (if used as an...

The major performance objectives of the next-generation wireless communication systems are high link capacity and increase application/service performance from the user perspective. An attractive technology for providing broadband access is WiMAX network. For the network and application-level capacity and performance analysis, we first provide an overview of WiMAX network architecture and syste...

Mobile Ad-hoc Network is a self configurable routing protocol. Nodes in MANET can shift freely from one place to another place and each node in MANET can take action as a transmitter, receiver and router. WiMAX is a telecommunication technology standard which provides fixed and mobile Internet access. Access Server Network (ASN) in WiMAX provides the layer 2 connectivity to the user equipments....

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...
