This paper describes about how you can secure your Wireless Network from hackers about various threats to wireless networks, How hackers makes most use of it and what are the security steps one should take to avoid becoming victim of such attacks. There are plenty of opportunities to connect to public Wi-Fi hotspots when you're on the go these days. Coffee shops, hotels, restaurants and airport...

Wi-Fi technology has always been an attractive solution for catering the increasing data demand inmobile networks because of the availability ofWi-Fi networks, the high bit rates they provide, and the lower cost of ownership. However, the legacyWiFi technology lacks of seamless interworking betweenWi-Fi and mobile cellular networks on the one hand, and between Wi-Fi hotspots on the other hand. ...

Fiber to the Rooms paradigm is gaining a lot of attention recently. In this paradigm, the last mile wireless (viz., IEEE 802.11x) connectivity, backed by optical fiber infrastructure, supports uncompressed high data rate while rendering seamless mobility and higher frequency reuse. To provide cost effective solution, Access Points (AP) in each room are replaced by distributed antennas. A centra...

With the rapid growth of wireless access networks, various providers offer their services using different technologies such as Wi-Fi, Wimax, 3G, 4G and so on. These networks compete for the scarce wireless spectrum. The spectrum is considered to be a scarce resource moderated by the spectrum allocation regulatory (“regulatory” for short) which is the governance body aiming to maximize the socia...

W i-Fi—consisting of the IEEE 802-11a, 802.11b, and 802.11g technologies—has proven to be a fast wireless-networking approach that is relatively easy and inexpensive to implement. The technology is particularly popular in North America and Asia. About 21 million Wi-Fi (short for wireless fidelity) cards will ship worldwide this year, and 33 million will ship in 2004, said Gemma Paulo, senior an...

The Next Generation Wireless Systems (NGWSs) consists of heterogeneous wireless access networks such as UMTS, Wi-Fi, WiMAX and LTE where Mobile Users (MUs) can access these technologies and services using a single device. This device is equipped with multiple radio interfaces include devices capable of supporting multiple Radio Access Technologies (RATs) by incorporating several interface cards...

Background: The radiation emitted from electromagnetic fields (EMF) can cause biological effects on prokaryotic and eukaryotic cells, including non-thermal effects. Objective: The present study evaluated the non-thermal effects of wireless fidelity (Wi-Fi) operating at 2.4 GHz part of non-ionizing EMF on different pathogenic bacterial strains (Escherichia coli 0157H7, Staphylococcus aureu...

The development of wireless internet infrastructures is progressing at a staggering pace. As the telecom sector emerges from the collapse of the internet bubble, incumbent wireless carriers, as well as a plethora of new start-ups, are investing in a range of technologies that offer near ubiquitous mobile access to the internet. Alongside these corporate efforts, there is also a bottom-up altern...

Wireless networking has become an important area of research in academic and industry. The main objectives of this paper is to gain in-depth knowledge about the Wi-FiWiMAX technology and how it works and understand the problems about the WiFiWiMAX technology in maintaining and deployment. The challenges in wireless networks include issues like security, seamless handover, location and emergency...
