Wireless networks have significantly impacted the world, since their initial deployment. Wireless networks have continued to develop and their uses have significantly grown. Cellular phones are nowadays part of huge wireless network systems and people use mobile phones on a daily basis in order to communicate with each other and exchange information. Recently, wireless networks have been used for positioning as well, in order to enable the provision of location oriented services to the end-user. Different types of measurements available during standard network and terminal operation, mainly for resource management and synchronization purposes, can be employed to derive the user’s location. With these numerous uses of wireless network, this project will focus on resources sharing dedicated network. A professor at the University of Hawaii, Norman Abramson developed the world’s first wireless computer communication network, ALOHAnet (operational in 1971), using low-cost ham-like radios. The system included seven computers deployed over four islands to communicate with the central computer on the Oahu Island without using phone lines. WLAN hardware initially cost so much


that it was only used as an alternative to cabled LAN in places where cabling was difficult or impossible. Early development included industry- specific solutions and proprietary protocols, but at the end of the 1990s these were replaced by standards, primarily the various versions of IEEE

802.11 (in products using the Wi-Fi brand name). An alternative ATM-like 5 GHz standardized technology, HiperLAN/2, has so far not succeeded in the market, and with the release of the faster 54 Mbit/s 802.11a (5 GHz) and 802.11g (2.4 GHz) standards, it is even more unlikely that it will ever succeed. In 2009 802.11n was added to 802.11. It operates in both the

2.4 GHz and 5 GHz bands at a maximum data transfer rate of 600 Mbit/s.


Most  new   routers  are  able  to  utilize  both  wireless  bands,  known   as dualband.   This  allows  data  communications  to  avoid   the  crowded

2.4 GHz    band,    which    is    also    shared    with Bluetooth devices    and microwave ovens. The 5 GHz band is also wider than the 2.4 GHz band, with more channels, which permits a greater number of devices to share the space. Not all channels are available in all regions.

A wireless local area network (WLAN) links two or more devices using some  wireless  distribution  method  (typically spread-spectrum or OFDM radio), and usually providing a connection through an access point to the wider Internet. This gives users the ability to move around within a


local coverage area and still be connected to the network. Most modern WLANs are based on IEEE  802.11 standards,  marketed  under  the Wi-  Fi brand name. Wireless LANs have become popular in the home due to ease of installation, and in commercial complexes offering wireless access to their customers; often for free. New York City, for instance, has begun a pilot program to provide city workers in all five boroughs of the city with wireless Internet access. Likewise, Muritala International Airport, Lagos has free wireless internet access for passenger travelling.



Most of us have become accustomed to the limitations that come with a wired network. When we want to check our email or print a report we find ourselves confined to a certain location or cramped space. In the past few years, the growing popularity of wireless communication has caught the attention of corporate, manufacturing, and academic settings. Wireless network technology has proven it can deliver the benefits of a wired network with the added benefit of computing freedom and share resources.



There is existing LAN connection but there are some features its lacking which inspired me to implement this project. There is no share


printer/resource; no   dedicated network  irregularities  etc.,   upon completion of this project, all of these drawbacks would be taken care of.
