ABSTRACT
The basic problems of wireless access are that the available spectrum is too limited and there is great attenuation of energy.These can be solved by frequency reuse and by reducing the maximum distance from the terminal to the nearest base station.
Distributed wireless communication system (DWCS) is a new architecture for a wireless access system with distributed antennas, distributed processors, and distributed controlling. The basic idea is to flatten the tree cellular structure. With distributed antennas, syste ....etc

SEMINAR REPORT ON WIRELESS LAN SECURITY
Abstract:
a. The 802.11 Wireless LAN Standard
In 1997, the IEEE ratified the 802.11 Wireless LAN standards,
establishing a global standard for implementing and deploying Wireless
LANS. The throughput for 802.11 is 2Mbps, which was well below the IEEE
802.3 Ethernet counterpart. Late in 1999, the IEEE ratified the 802.11b
standard extension, which raised the throughput to 11 Mbps, making this
extension more comparable to the wired equivalent. The 802.11b also

Abstract”
In the presented paper, the principle of frequency domain channel estimation for wireless OFDM systems will be shown. A well known noise reduction technique will be adapted to HIPERLAN/2 and IEEE802.11a standards, and its positive effects will be demonstrated by simulation results. Channel tracking has not been considered by the WLAN standards named above, although it is well known that time-variant indoor radio channels can change their characteristics within one PHY burst. This paper presents some techniques for decision ....etc

INTRODUCTION

With the rapid progress in telecommunications, more and more services are provided on the basis of broadband communications, such as video services and high-speed Internet. With worldwide fundamental construction of a backbone network based on optical fiber providing almost unlimited communications capability, the limited throughput of the subscriber loop becomes one of the most stringent bottlenecks.Compared to the capa ....etc

Conclusion
What is WI-FI
This is wireless fidelity.
Wi-Fi is a wireless network protocol often used for wireless local Area networks (WLANS).
It enables multiple devices to share a single high-speed Internet connection over a distance of about 300 feet.
WLANs are local area networks of PCs without wires.
Data transmission is through air using radio frequency or infrared frequency instead of wires.
