Wireless LANs have gained popularity in areas such as the health-care, retail, manufacturing, warehousing and academia markets (Kurose, 2003). Some widely known wireless technology in use in devices includes, cameras, automobiles, security systems, and kitchen appliances. Wireless LANs use electro magnetic airwaves (radio or infrared) to transmit information from one point to another without relying on any physical connection (Dean, 2000). Radio waves often are referred to as radio carriers because they simply perform the function to delivering energy to a remote receiver. Networking firms have a range of technologies to choose from when constructing wireless LANs.

The IT, or Information Technology has become a standard and very critical part of today’s society. Wireless technology came from the basic just cellular usage to sensors in the medical field. Wires are now a thing of the past in today’s world with forever revitalizing technology. Wi-Fi (Wireless Network) or 802.11 networking is a phenomenal way of providing Internet wirelessly at a low cost. Using radio waves, a wireless network connects a PC, mobile phone or just about anything that connects to the internet wirelessly by a router.

The reason computer user are using network system is to share document, software but also help transmit internet signal through their network making internet accessibility in the area they preferred. There many network but the most common use are WAN, LAN, and MAN. The WAN network covers large area like a city, a country or the world. The LAN is the one people use at home and it covers a limited area. The WAN is control by a network provider like cablevision and use a lot LAN to provide internet service.

The technology is also used in hospitals and in universities to connect cabled networks in different buildings. The number of wireless LANs in the world are increasing rapidly because of the advantages they have. Section B: Sho... ... middle of paper ... ...unauthorized persons. Therefore one should make sure that his laptop is kept to high security levels by updating antivirus and spyware programs, installing firewalls, use strong passwords, and be aware of email attachments and file downloads. Section D: Valid reasons to invest in Wi-Fi It is worth investing in wireless networks because it has many benefits and this is shown from the deployment which is taking place in universities all around the world.

Once a connection is established between the user and the network, the user will be prompted with a login screen and password if it is a fee-based type network. Though there’re also free-based network connections as well in some areas. Wi-Fi networking around the world is creating hot spots in cities where anyone with a laptop can wirelessly plug into the internet.

By freeing information from the restrictions of a desk or search for a nearby Wi-Fi hotspot, people can quickly retrieve and exchange information. This is great for a business at it allows people to access their website easier as they do not have to do it from a desktop computer or laptop, providing a vast connectivity. Many people use their mobile phone carriers internet 3G/4G towers to search the web. It allows fast internet connections and by carrying a mobile phone it is a lot more portable than a normal computer. These days the mobile phone is peoples life, wherever they go, the phone goes.

SECURING THE ENTERPRISE WIRELESS LAN Enterprise wireless LAN deployments have advanced in recent times , emerging from guest access in conference rooms, to limited hot zones of connectivity by highly authorized users within the enterprise to full coverage throughout the company/organization. Unfortunately many of these deployments are still insecure, leaving opportunities to try and access confidential enterprise information for the just curious or malicious hackers. Securing a wireless LAN is not so hard, Industry advances in the field of technology and vendor innovation makes this easier than ever before. Following are some best practices for securing enterprise wireless LAN. 3.1 CHANGE THE MANUFACTURER’S DEFAULT SSID TO A ‘SECURE’ SSID To advertise the availability of the access points these were given standard network names such as Linksys, tsunami, default, etc that broadcast to clients.

The only real complaint that we heard about Wi-Fi is that there are security issues. Hackers have been known to drive around accessing people’s wireless networks. So security is an issue. One way to deal with security is to use WEP (wired equivalent privacy). This technology allows us to use wireless and still have some of the same protection as with a wired network.

Businesses try to filter Spam by using blockers but these attempts may fail, because Spam is sent out in its millions this can clog up the internet network causing computers to rum slow or even crash. E-mail E-mail is short for electronic mail. E-mail is not only for fun but plays a large part in effective communication between major businesses. Almost everybody connected on the internet has an e-mail account. Accounts are free and can be achieved by singing up with companies such as yahoo, AOL and hotmail.

The quite of wire used though, the standard copper wire can be easily manipulated and data packets stolen, optical fibers are way safer though. In one way we cannot be sure of being safe ever. The internet is a rapidly growing field and securing the flow of data is surely getting harder day by day. Wireless is ideal for providing network access in meetings or common areas and can also be used to offer internet access to visitors. There is a number of wireless networking standards too.
