End users in a wireless local area network access the network through adapters such as PC cards in laptop notebook computers. And PCI cards in desktop computers. These cards provide the interface linking the network operating system (NOS) and the airwaves by means of an antenna. The wireless connection is clear to the network operating system as well as to those using the network, and it supports applications such as electronic mail (e-mail), access to shared peripherals, and access to multi-user databases and applications. Wireless LANs have gained popularity in areas such as the health-care, retail, manufacturing, warehousing and academia markets (Kurose, 2003).
It has a lot of scope for usage from networking to pairing devices, it provides a wireless connections. There are many other devices, like Smartphone, tablets, Laptops, etc which have Wi-Fi client so that they can access any of the Wi-Fi access point or hotspot to access data services or internet. Research Wi-Fi is a known technology and works on the protocols as defined by IEEE (Institute of Electrical and Electronics Engineers) 802.11 standards. The name Wi-Fi is used as a synonym for Wireless LAN or WLAN. Normally the range of any wireless access point is few meters, however as it work on microware, the range reduces with any kind of obstacles such as wall.
Survey of Wireless Computing Abstract Wireless technology can provide many benefits to computing including faster response to queries, reduced time spent on paperwork, increased online time for users, just-in-time and real time control, tighter communications between clients and hosts. Wireless Computing is governed by two general forces: Technology, which provides a set of basic building blocks and User Applications, which determine a set of operations that must be carried out efficiently on demand. This paper summarizes technological changes that are underway and describes their impact on wireless computing development and implementation. It also describes the applications that influence the development and implementation of wireless computing and shows what current systems offer. 1 Introduction Wireless computing is the topic of much conversation today.
The world has gone through a lot of changed as time passes by. With advancements in the technological field people are can communicate with ones from around the world without having to even lift a finger. To make things more efficient and more cost saving industries have made technology wireless. Wireless technology gives people the chance to get up from their stationary computer, or cord phone and able to freely move without restrictions. The IT, or Information Technology has become a standard and very critical part of today’s society.
This enhances usability and in some sense, creativity. Wireless internet isn’t really that hard to setup. You need an access point, a server, and a laptop. After that, it’s all a matter of configurations and you’re in. The only real complaint that we heard about Wi-Fi is that there are security issues.
Wireless Networking Basics According to (Vacca, JR 2006) The term wireless networking means the technology that facilitates two or more computers to communicate using standard network protocols, but without network cabling.

Introduction Wireless communication has improved dramatically in the last few years. Their networks are indispensable providing the means for mobility, city-wide Internet connectivity, distributed sensing and outdoor computing . It allows the transfer of messages between people that are on the other side of the world. Without wireless communications people would not have a lot of the devices many 21st century citizens could not live without, namely the smartphone. It is also required for devices using Bluetooth, remote controls, Wi-Fi; really any electrical devices that communicate via a wireless or wired channel .
This approach consists of two tokens: Passport (identification token) and Visa (authorisation token) to provide a flexible authentication method for foreign network to authenticate mobile users. The security analysis indicates that our proposal is more secure and suitable for ubiquitous mobile communications specially in roaming agreement-less enviroment. Keywords: authentication, ubiquitous wireless access, security protocols, roaming agreement, telecommunication security. Introduction The advanced capabilities of mobile devices and wireless technologies facilitate accessing variety of services over the Internet: e-mail, mobile commerce and mobile banking. It becomes more desirable to mobile users (MU) to access these services wirelessly while they are o... ... middle of paper ... ...munications Magazine, vol.
Transmission of Multimedia Data over Wireless Ad-Hoc networs A. Berk Barutlu Abstract Ad-hoc networking has been of increasing interest and therefore recognized as an important research area in recent years. This paper is about transmission of multimedia data over wireless ad-hoc networks, the problems and the related issues. 1. Introduction 1.1 Ad-Hoc Networks An ad-hoc network is a collection of wireless mobile nodes that will dynamically form a temporary network without the use of any existing network infrastructure. The technological developments that have enabled ad-hoc networks are divided into two major groups; the first group is the devices that are small and light enough to carry them around like printers, laptops, PDA’s,… etc., and the second group is wireless network interfaces, like WirelessLAN, Bluetooth, GSM,… etc., that are available for these types of devices .

It is also easier to provide network connectivity in difficult locations to access, such as warehouses or manufacturing plants. • Scalability: a wireless LAN can usually be extended with existing equipment, so that a cable network may require extra cables or other equipment. • Safety: the control and management of access to your wireless LAN network are important aspects for the success of its implementation. The latest advances in WiFi technology provide robust protection and allow you to ensure that your data are easily accessible through the wireless LAN network only to authorized persons.
