WiMAX Networks:Services and their Quality Matrics
نویسنده
چکیده
WiMAX is the worldwide interoperability for microwave access, to provide business and consumer world wireless broad band services in metropolitan area networks. It has a target range of 31 miles and a target transmission rate exceeding 100 Mbps. Mobile WiMAX is an OFDM based technology for deployment which allows multiple-antenna operations to be performed on vector-flat sub carrier. Fixed WiMAX, which is based on IEEE 802.16-2004, uses a 256 FFTbased OFDM physical layer. Mobile WiMAX, which is based on the IEEE 802.16e-2005[5] standard, uses a scalable OFDM-based physical layer. It integrates wireless technology specific functionally with IP networking equipment. Enables the use of mobile devices and optimizes handovers. This paper presents an overview of WiMAX, its key features and its

متن کاملGeneral and social cognition in first episode schizophrenia: identification of separable factors and prediction of functional outcome using the IntegNeuro test battery.
OBJECTIVE It is increasingly recognized that cognitive assessments, unlike symptom ratings, provide a reliable predictor of functional outcome in schizophrenia. This study evaluated the utility of the 'IntegNeuro' computerized test battery for assessing cognition in first episode schizophrenia. We determined the presence of separable factors of general and social cognition, their equivalence to...

متن کاملSurvey & Assessment of Wimax, its Security Threats and Their Solutions
For a broadband wireless standard such as WiMax, security is important and must be addressed. This is to ensure wide acceptance both from the perspective of the end users and the service providers. In order to compete with existing broadband cable or DSL services, the WiMax network must offer comparable security. We discuss the WiMax security mechanisms for authentication, encryption, and avail...
متن کاملQuality of Service Differentiation in WiMAX Networks 753 Quality of Service Differentiation in WiMAX Networks
Broadband Wireless Access (BWA) based on the IEEE 802.16 standards [IEEE 802.16, 2004] [IEEE 802.16, 2005], also known as Worldwide Interoperability for Microwave Access (WiMAX), is gaining momentum as more and more field trials are transformed in commercial roll-outs. Very much likely, this is certainly a merit of the combined effort of the IEEE 802.16 standardization community, the WiMAX Foru...
