Parameters Effecting 2D Barcode Scanning Reliability

This paper describes a case study to identify the various parameters that affect the scanning reliability of 2D barcodes for high content density applications. A review of the numerous options for 2D symbologies showed that, in theory, these symbologies are capable of encoding relatively large amounts of data, but in practice, barcode scan-ability decreases as the encoded content increases. Wit...

Mobile WiMAX Network Security

WiMAX networks provide broadband data access to mobile as well as stationary users. While the wireless link is based on the 802.16e-2005 specification developed by IEEE, a complete network architecture “behind the base station” with global roaming support has been specified by the WiMAX forum. The security architecture for these networks covers EAP/AAA-based secure network access, secure bootst...

Performance Analysis of Downlink Mimo in 2x2 Mobile Wimax System

In this paper, we analyze the error rate performance of downlink coded multiple-input multiple-output orthogonal frequency division multiple access (MIMO OFDMA) systems under frequency selective fading channel conditions. The IEEE 802.16 standard, commonly known as WiMAX, is the latest technology that has promised to offer broadband wireless access over long distance. Since 2001 WiMAX has evolv...

Analysis and Simulation of Fractal Antenna for Mobile Wimax

The growing demand of wireless services requires the definition of new standards able to provide an increased degree of mobility for the end user and a higher speed of data transmission. Among emerging standards, one of the most promising is the IEEE 802.16 Wireless Metropolitan Area network Air Interface (generally called Wimax).In last few decade the miniaturization led antenna to be conforma...
