wirerless LAN technology

                   WIRELESS LAN TECHNOLOGY

         wireless lan in data communication

It is a wireless computer  network connection .Two  or more services using  a wirrerless distribution method with in a limited area as in  school or offrice building etc.

it provides mobility within coverage area .

Two popular standardizing organizarrtion which support wireless lAN are IEEE & ETS.

IEEE stands for the  instirtute of Electrrical Electronics Enginering .

ETSIstands for the European Telecommunication Standard Interfaces.

                                       ADVANTAGES AND FEATURES.

*LAN EXTENTION.

In this we donot need to use lan extention to increase our disrtant limitation or to extend the network access. wireless lan covers only the nework with in a building office only .

*CROSS BUILDING  INTERCONNECTION.

It is the best feature and advantage of lan because it can be connected with another lan easily  without any physical connection .It uses buffers to connect with the other lans .

*FLEXIBILITY.

Flexibility make the wlan more attractive than  a physical lan because it can be flaxible as the size of an office with the use of  buffers . In this lan we dont need an extra piece of wired connection to extend our connection .

*INCREASED MOBILITY & COLLABORATION.

Wireless lan gave us the freedom of mobility to use  the wlan in different places  . It refers that if an office is shifting from karachi to lahore than this lan can be used in lahore same as it was uses in karachi.

*ENHANCE GUEST ACCESS.

Wireless lan also gives us the possibility of more connection in a lan without disturbing the existing lan network . It means we can add or remove the  any node in the lan witout any disturbance in the lan system settings .

*USAGE.

Wireless lan is easy and best way to connect with in a network connecrtion . you just need to connect with the device using  your device with the lan  device once anywhere within the limitations of the lan connection and  you will become a part of the lan.

                                                     DISADVANTAGES.

*TRANSMISSION QUALITY.

Wireless lan quality is low due to its wireless connection signals can be sometimes slow and fast .

sinals can be distured for many reasons.

*EQUIPMENT COST.

Wireless lan equipments and its devicre is costly as compared to the physical lan network. it can  be increase the costr of the whole setup.

*SECURITY.

Wireless connection is always unsafe from the hackers . The hackers can hack ther wireless connection lan and also they can disturb the connection settings or may stole the important informtion
