TL;DR: This paper provides the analysis of the broadband wireless access (BWA) technology by using WiMAX technology and compares it with the other wireless technology like Wireless Fidelity (Wi-Fi) and third-generation (3G).
Abstract: Worldwide Interoperability for Microwave Access (WiMAX) is a broadband wireless access technology which brings the broadband experience to a wireless context. There are two different types of broadband wireless services. One is fixed wireless broadband which is similar to the traditional fixed line broadband access technology like DSL or cable modem but using wireless as a medium of transmission. Another type is the broadband wireless known as mobile broadband which has additional functionality of portability, mobility and nomad city. The IEEE 802.16 family WiMAX is designed to accommodate both fixed and mobile broadband applications. WiMAX offers higher peak data rates and greater flexibility than 3G networks and Wi-Fi. This paper provides the analysis of the broadband wireless access (BWA) technology by using WiMAX technology and compares it with the other wireless technology like Wireless Fidelity (Wi-Fi) and third-generation (3G).

TL;DR: The Telecommunication Information Networking Architecture (TINA) is an open architecture unifying the telecommunication management network (TMN) and the intelligent network (IN) architectures together that provides more flexibility in application interoperability, and facilitates a faster application development.
Abstract: The broadband and multimedia are changing our life style. It provides the opportunity for scanning 500 channels, video-on-demand (VOD) in real-time, interactive games, home shopping, distance learning, telecommuting, etc. The national information infrastructure, regional information highways, and other broadband initiatives have created the need for a new service architecture. The broadband development can be revolutionized by a flexible operations and network architecture. The Telecommunication Information Networking Architecture (TINA) is an open architecture unifying the telecommunication management network (TMN) and the intelligent network (IN) architectures together. It provides more flexibility in application interoperability, and facilitates a faster application development. The information superhighway is considered as highway of broadband communications networks with ramps connecting different service/shopping centers of information providers. The video dial tone (VDT) and interactive services are based on integrated broadband communications network. The VDT and interactive services have both service and management oriented features and functionalities. The TINA having both capabilities TMN (to support management aspect) and IN (to support service aspect) is most suitable for the VDT and interactive services.

01 Jan 2001TL;DR: This work suggests applying multi-carrier spread spectrum (MC-SS) techniques to fixed wireless access applications that are robust against multipath effects and can provide service coverage not only to line-of-sight (LOS) subscribers but also to nearly LOS subscribers.
Abstract: We suggest applying multi-carrier spread spectrum (MC-SS) techniques to fixed wireless access applications. In these applications, cross-polarization discrimination and directional subscriber antennas can be used to reduce interference in multi-cellular systems. Power control is applied on both uplink and downlink. The suggested system has a high capacity and uses a simple multi-access layer. It is robust against multipath effects and can provide service coverage not only to line-of-sight (LOS) subscribers but also to nearly LOS subscribers. Only a single carrier frequency is used in the entire network.

TL;DR: Regulatory implications of the deployment of wireless heterogeneous networks, standardisation and technology neutrality, spectrum management, market analysis, open access and infrastructure sharing, interconnection pricing and charging, broadband deployment policies, and privacy and security issues are analyzed.
Abstract: A wireless heterogeneous network can help increase the access transmission speed and contribute thereby to the broadband deployment policies of administrations and telecommunications operators Given the technical particularities of wireless heterogeneous networks, the deployment of wireless heterogeneous networks raises a number of challenges that need to be addressed by regulatory authorities This article analyses the following regulatory implications: standardisation and technology neutrality, spectrum management, market analysis, open access and infrastructure sharing, interconnection pricing and charging, broadband deployment policies, and privacy and security issues

TL;DR: The role of self-similarity in the development of bandwidth capacity modelling techniques is examined and the results of a case study analyzing Internet traffic on a global broadband network are presented.
Abstract: Self-similarity is a major assumption used in the modelling and characterization of Internet traffic. This paper examines the role of self-similarity in the development of bandwidth capacity modelling techniques and then presents the results of a case study analyzing Internet traffic on a global broadband network. Most modelling techniques of today express network traffic as a function of fractal Browning Motion, as proposed by Ilkka Norros [1], which are based on assumptions that the traffic is self-similar and long range dependant. This study analyzed the network traffic characteristics of airline users on an example broadband network. The data was collected from four different gateways at geographically diverse locations. Collected data was analyzed for self-similarity and the applicability of fractal Browning motion. A distinct trend away from self-similarity was observed and probable causes are postulated.
