WIRELESS NETWORK SECURITY

WIRELESS NETWORKS

Wireless Network is the linking two or more computer without the use of any wires . Thirty years ago , entrepreneurs , real estate agents and trades people incorporated pagers and cell phones into their work and personal lives for one central reason : productivity . Wireless

connections meant they could more rapidly interact with customers partners and suppliers . Over time , wireless users have had more exposure to key business applications such as appointment scheduling , customer relationship management and supply chain management software

Bluetooth wireless technology has become a global specification for "always on " wireless communication between portable devices and desktops . Simply put , it 's a way for devices such as PCs , handhelds , and cell phones , to "talk " to each other and synchronize data--all without wires . As more companies begin to create Bluetooth-enabled devices , look for the technology to explode by year 's end . The first set of Bluetooth-enabled devices will ship midyear . Bluetooth has a range of up to 30 feet , giving users greater mobility in the workspace . Unlike infrared connections , users don 't have to have a line-of-sight connection to the device being accessed . Plus , without cables , the work environment looks and feels more comfortable

Bluetooth can also be used to make wireless data connections to conventional local area networks (LANs ) through an access point equipped with a Bluetooth radio transceiver that is wired to the LAN . For example , you can reply to an e-mail on your PDA , tell the device to make an Internet connection through a mobile phone , print a copy of the e-mail on a printer nearby , and record the original on the desktop PC--all while walking down the hall

Since its development in 1994 by Ericsson , more than 1 ,800 companies worldwide , including Motorola , have signed on as members of the Bluetooth Special Interest Group (SIG ) to build products with the wireless specification and promote the new technology in the market

But with any new technology , there 's a downside . And this one is no different . With Bluetooth , you can synchronize all of your devices only as long as they are within that 30-foot range . Beyond that , you 're out of luck . And if you want to synchronize data with others , for example you want to share your contact list with a colleague setting up Bluetooth to do this can be a tedious and involved process . In this case , infrared might be a better option

Today , laptops , PDAs and tablet computers with embedded 802 .11 chips are answering a similar productivity challenge laid down by IT management even more than wired networks . WLANs assure a mobile "always on computing environment , allowing knowledge workers to constantly be in contact with their data and applications

Several applications have emerged that take advantage of the benefits...
