The article presents a structure of human shape microstrip patch antenna operating at dual frequencies. In this paper a rectangular patch of human shape cutting is proposed. The human shape antenna is designed for wireless applications, which works at 2.4 GHz and 5.4 GHz frequencies. This proposed antenna can be widely used for Wi-Fi (IEEE 802.11 standard), BLUETOOTH, WLAN, WiMAX (IEEE 802.16 a...

A significant body of research has addressed whether fixed internet use increases, decreases or supplements the ways in which people engage in residential and workplace settings, but few studies have addressed how wireless internet use in public and semi-public spaces influences social life. Ubiquitous wi-fi adds a new dimension to the debate over how the internet may influence the structure of...

The population of smart mobile devices drives the mobile traffic growth rapidly. To deal with the traffic explosion, heterogeneous radio network integration is considered as a cost-effective solution for mobile operators to reduce network congestion. With the coverage overlapping of various wireless networks (e.g., LTE and Wi-Fi), we can use multiple networks to transfer different services simu...

Since the IEEE ratification of the 802.11 standard in 1999, continuous exploits have been discovered compromising the confidentiality, integrity and availability of 802.11 networks. This paper describes the justification for a project to assess the security status of wireless network usage in society. It reviews the status of both commercial and residential approaches to wireless network securi...

Nowadays, the more and more popular location based applications require accurate position information even in indoor environments. Wireless technologies can be used to derive positioning data. Especially, the Wi-Fi technology is popular for indoor localization because the existing and almost ubiquitous worldwide Wi-Fi infrastructure can be reused lowering the expenses. However, the primary purp...

Video transmission over wireless links is becoming an interesting issue in modern communication networks. The paper presents a framework for modeling and providing an optimal solution to the problem of power control in transmission of embedded video over a single Wi-Fi link. The approach, based on a constrained optimization problem, is then compared with equal energy distribution, demonstrating...

Abstract Li-Fi (Light Fidelity) is a new wireless communication technology that comparable to Wireless Fidelity (Wi-Fi). However, supposed be better than Wi-Fi, and this has been theoretically verified. also thought make significant contribution networks. The practical application of will discussed in study. In paper we chose NOMA because its ability efficiency simultaneously transporting data,...
