Description

INTRODUCTION:

Wimax stands for Worldwide Interoperability for Microwave Access. Wimax technology is a telecommunications technology that offers transmission of wireless data via a number of transmission methods; such as portable or fully mobile internet access via point to multipoints links. The Wimax technology offers around 72 Mega Bits per second without any need for the cable infrastructure. Wimax technology is based on Standard that is IEEE 802.16, it usually also called as Broadband Wireless Access. WiMAX Forum created the name for Wimax technology that was formed in Mid June 2001 to encourage compliance and interoperability of the Wimax IEEE 802.16 standard. Wimax technology is actually based on the standards that making the possibility to delivery last mile broadband access as a substitute to conventional cable and DSL lines.

OBJECTIVES:

  • To suggest the solutions and the enhancements found during the research.
  • To validate that the new enhancements will provide more security and reliability in the other’s people research and context.
  • To gain in-depth knowledge about the WiMAX technology and how its works
  • To understand the problems about the WiMAX technology in maintaining and deployment.

 

 

 

PROBLEM STATEMENT:

WiMAX is a great technology for next generation with potential applications such as cellular backhaul, hotspot, VoIP mobiles and broadband connection but it have some problems as under.

Speed of connectivity

The WiMAX other drawback is that any user closer to the tower can get high speed which is up to 30Mbit/s but if a user exists at the cell edge from the tower can obtain only 14Mbit/s speed.

WiMAX range

The other disadvantage of WiMAX network is range. As WiMAX offer 70Mbps in range with moving station but in practice it is quite different because it is possible only in specify or ideal circumstances. If a user staying away from the specified environment then speed can drop considerably.

WiMAX Bandwidth

Like other network Bandwidth is collective amongst clients in a specified zone. But if there are a lot of users in one area the speed decreases which may be 2 to 10 Mbps of shared bandwidth.

Expensive network

The most disadvantage of WiMAX is its installation and operational cost. Due to heavy structure, tower, antennas etc. makes the WiMAX network collectively high cost network.

 

Power consuming

WiMAX network is very heavy in structure therefore need much electrical support for running the overall network.

Bad Weather

The quality of services decreases in rainy season because the weather condition could interrupt the signal which may cause of bad signal and broadcasting may be stop or interrupted.

 

LITERATURE SURVEY

 

  • Zakhia Abichar, Yanlin Peng, and J. Morris Chang in 2006 shows WiMax: The Emergence of Wireless Broadband The much-anticipated technology of WIMax,the Worldwide Interoperability for Microwave Access, aims to provide business and consumer wireless broadband services on the scale of the Metropolitan Area Network (MAN).WiMax will bring a standards- based technology to a sector that otherwise depended on proprietary solutions.The technology has a target range of up to 31 miles and a target transmission rate exceeding 100 Mbps and is expected to challenge DSL and T1 lines (both expensive technologies to deploy and maintain) especially in emerging markets.

 

  • Chizu Fukao Jun in 2007 Study on the Detection Scheme of WiMax signal for DAA Operation in MB-OFDM. In the first, by comparing the power 1-3 of the WiMax signal derived from the FFT outputs of the MB-OFDM receiver with the background noise, power detection scheme is performed. And using the central limit L theorem, Correlation detection comparing power detection scheme. It was confirmed that this scheme has much better performance than the power detection scheme under low signal to noise ratio situation. Therefore, it references is considered that the use of the guard interval information  “Ultra-Wide Bandwidth

 

  • Dusit Niyato and Ekram Hossain  in 2007 shows Integration of WiMax and WiFi Broadband wireless access networks based on WiMax can provide backhaul support for mobile WiFi hotspots. We consider an integrated WiMax/WiFi network for such an application where the licensed WiMax spectrum is shared by the WiFi access points/routers to provide Internet connectivity to mobile WiFi users. The WiMax backbone network and WiFi hotspots are operated by different service providers. Issues such as protocol adaptation, quality of service support, and pricing for bandwidth sharing that are related to integration of these networks are discussed. In addition, they propose a model for optimal pricing for bandwidth sharing in an integrated WiMax/WiFi network

 

 

 

METHODOLOGY:

RESEARCH DESIGN

A Research Design is the framework or plan for a study which is used as a guide in collecting and analyzing the data collected. It specifies the methods and procedures for acquiring the information needed to conduct the research effectively.

 

METHODOLOGY TO BE USED:.

  • Discussion about the security functions of WiMAX technology
  • Research about the basic security requirements for the WiMAX technology
  • Study of recent development in the WiMAX technology security
  • Discuss proposals for the solution of threats to WiMAX technology.
  • Discuss about the future of WiMAX technology and related work for enhancements.
  • Study and investigation of technical features of the WiMAX network.
  • Research about the requirements for the deployment of the WiMAX technology
  • Negative aspects of WiMAX technology security & discuss threats and other vulnerabilities.

 

 

DATA COLLECTION TECHNIQUES:

PRIMARY DATA:

 

The primary data will be gathered through personal interaction with various functional heads and other technical personnel.

SECONDARY DATA:

Secondary data will be collected from various reports / documents charts, management information systems, etc. and also will be collected from various magazines, newspapers, books, and internet.

 

Sampling: It is not always necessary to collect data from whole universe. A small representative sample may serve the purpose. A sample means a small group taken in a large lot. This small group taken in a large lot .This small group should be emanative cross section and really “representative” in character. This selection process is called sampling.

 

Sample size: Samples are devices for learning about large masses by observing a few individuals. The sample will be selected 100.

Population:-

All the employees of the organization

Methods of Sampling

Random sample method:

The method will be adopted here is random sampling method.  A Random sample is one where each item in the universe has as an equal chance of known opportunity of being selected.

Sampling techniques:- Random sampling method.
