AN OVERVIEW OF THE WIRELESSNETWORKING

Here you will find wireless networking tutorials, what is wifi, general securioverview, wlans, wpans, wmans, wep and wireless access control overview.Whether you want to make a phone call from your mobile, received a messaon your pager, checked your email from a PDA we have come across a wirel

data or voice network.

WIRELESS NETWORK TYPES

Wireless Local Area Networks (WLANS)

Wireless Personal Area Networks (WPANS)

Wireless Metropolitan Area Networks (WMANS)

Wireless Wide Area Networks (WWANS)

WIRELESS LOCAL AREA NETWORKS (WLANS)

WLANS allow users in local area, such as in a university or a library to formnetwork and gain wireless access to the internet. A temporary network canformed by a small number of users without the need of access point; given tthey do not need to access the resources.

WIRELESS PERSONAL AREA NETWORKS(WPANS)

There are two current technologies for wireless personal network Bluetoand Infra Red. These technologies will allow the connectivity of persdevices within an area of 30 feet. Infra Red requires a direct line and the rais less as compared to Bluetooth technology.

WIRELESS METROPOLITAN AREA NETWORKS(WMANS)

WMANS allow the connectivity of multiple networks in a metropolitan asuch as building in a city. The network connectivity is the alternative of copor fiber cabling.

WIRELESS WIDE AREA NETWORKS (WWANS)

WWANS or Wireless Area Networks can be maintained over large areas such as indifferent cities or between different countries, via multiple satellite systems or antensites. The types of system are called 2G systems.The following table shows the range those different types of wireless network cover

The following different types of security methods are available in the wireless

networking.

WIRED EQUIVALENT PRIVACY (WEP)

Wired Equivalent Privacy is intended to stop the interference of rfrequency that is signaled by unauthorized users and this security measurmost suitable for the small networks. There is not key management protoand each key is entered manually into the clients thats why this is v

consuming administrative task. The WEP security method is based on the Rencryption algorithm. In the WEP all the client computers and Access poare configured with the same encryption and decryption keys.


9/14

SERVICE SET IDENTIFIER (SSID)

Service Set Identifier (SSID) acts a simple password by allowing WLnetwork to be split up into different networks and each having a unidentifier. These identifiers are configured in the multiple access points.access any of any networks, a computer is configured in such a way that eac

having a corresponding SSID identifier for that network. If the SSID ma between the two computers or networks then access is granted to each other.


10/14

MEDIA ACCESS CONTROL FILTERING(MAC ACCESS CONTROL)

A list of the MAC addresses of the client computers can be inputted into anAccess point and only those computers are granted to give the access to thenetwork. When a computer makes a request, its MAC address is compared tothe list of the MAC addresses to the Access point and based on this access

permission granted to deny.This is a good security method but it is mainly involved in the small wirelesnetworks because there is more manual work is involved of entering the MAaddress into the Access point.

BLUETOOTH

Bluetooth is a simple type of the wireless networking that operates in the digdevices, like mobiles phones, personal computers, PDA, Laptops, digital camera, M

players and other Bluetooth enabled devices to form a small network. In the Bluetotechnology eight devices can be connected to each other at the same time. Bluetocan also be found in the headsets, hands-free kits, wireless keyboards and mouBluetooth technology was invented by Ericsson in 1994 and after four years in 19some major mobile phone companies such as Nokia, Ericsson, Intel and Tosformed a group to promote this technology.

BLUETOOTH CONT .

Bluetooth technology falls in the category of personal area networking becait operates in the range of 30 to 300 feet. Bluetooth uses the radio wtechnology, which is not very expensive and has low power consumptMany different companies are intended to add the Bluetooth chip in t

digital devices. Bluetooth technology is getting very popularity because olow cost and portability.

THE FUTURE OF WIRELESS NETWORKING

WLANS wireless networking type is very popular in home networking and more th20 percent homes with broadband internet are using WLANS and this numbeincreasing. In a general estimate worldwide hotspots have now reached more t30,000 and will grow about 210,000 in the next few years. Most large hotels alreaoffer Wi-Fi and the business travelers are willing to pay wireless access. 802.11 is next Wi-Fi speed standard is set to offer bandwidth around 108Mbps and is still undevelopment. With the speed of 70 Mbps and a range up to 30 miles, the 80standard, known as WiMAX is sure to get boost.

SOME TIPS & TRICKS

When purchasing a wireless NIC card try to get one that is having external antennWhen you are out and using Wi-Fi enabled laptop, disable Microsoft file and sharinwhich enables other computers in a network to access data and resources on yourcomputer. In this way, your computer or laptop will be saved from hackers. If you are concerned about the interference from the other wireless access point se

the AP and wireless computers to use a non-overlapping channel. Change the configuration interface password of the access point before you enabl Only buy an access point that is having upgradeable capabilities. By this way youcan take the advantage of security enhancements. Keep the access point up to date.
