Broadband AND WiMAX



Broadband AND WiMAX

Introduction

Wi-Fi standards (802.11a, 802.11b and 802.11g), which became operational in the year 2,000, are beginning to fall short against the appearance of the new 802.16 standard. This technology is being developed by WiMAX Forum (Worldwide Interoperability for Microwave Access), representative whose two members are Intel and Nokia. Specifically, in 2001 created the WiMAX Forum, with over 230 members, to promote the standard and to help ensure the compatibility and interoperability across multiple vendors. The label WiMAX associated with the name of the standard. The key features of WiMAX include high Bandwidth: A single base station can support more simultaneous 60 links from T1/E1 connectivity type or hundreds of connections such as DSL. It is independent of protocol; which means you can carry IP, Ethernet, ATM and others (Gosh, 2005). That makes it compatible with other standards such as Wi-Fi, Ethernet, or Token Ring. Supports calls smart antennas (smart antennas), own networks telephony of third generation (3G), which improves the spectral efficiency. These antennas emit a very narrow beam that can be moving, electronically to focus on the receiver.

Discussion

Paper 1 (Article)

This paper is based on a survey on mobile WiMAX. This paper includes, that IEEE 802.16 is the latest standard quality technology which promises to provide long distance wireless access. WIMAX has moved to new technology IEEE 802.16e which provides the standards of mobility support. This paper includes all the details of WIMAX technology with association with cell phone development. The paper is focused in analyzing QOS provisioning and WiMAX mobile specification (Qin & Low, 2007). This paper is developed in Hong Kong University of Science and Technology.

Paper 2 (Article)

This paper is based, on service oriented and secures network control frame work for WiMAX network. WiMAX is a renowned technology which helps in providing long distance signals. It is a cost effective solution, so multihop communication is becoming important for the WiMAX system. Security is one of the biggest challenges in order to successfully deploy the multihop WiMAX network. In regard to security issue very little work has been done, because WIMAX is a modern world technology. This paper suggests the secure and service oriented network for the WiMAX networks. The frame work of secure and service oriented WiMAX network has been discussed in this paper in detail (Lu & Quain, 2007). This paper is developed in University of Puerto Rico.

Research question (Paper 1)

The discussion question in this research paper is based on the mobile phone advancement with association to WiMAX technology. The research question has been discussed in detail in the body of the research paper. The discussion is done on medium access control, PHY, BWA, OFDM, CDMA, QoS and IEEE 802.16.

Research question (Paper 2)

The research question is based on secure and service-oriented network and control framework for WiMAX networks. The paper is based on discussing the security and network control of WiMAX network.
