The Advantages Of Wireless Networks

In this world of modern technology, most people prefer not to connect computers with Ethernet cables because excessive cables scattered throughout their office or home is unsightly. You can choose to install a wireless network to avoid excessive cabling. For a wireless network, there is no need to use Ethernet cables to connect your computers to the DSL or router.

Usually, a wireless network broadcast signal uses one or more wireless routers or wireless access points. The access points or router are provided with an aerial and an Ethernet port. The Ethernet port in the access point must be connected to the modem which is provided by your internet service provider, if you need internet access. If you have to move the wireless network to another place, you can simply transfer and install it in your new location easily.

You can also make a combination of wired and wireless connections with an access point or wireless router. The access point functions as the receiver and radio frequency transmitter and can interact with computers, IP Phones, PDAs and other access points having 802.11 wireless adapters. IEEE 802.11 standard of wireless transmission is utilized in a wireless local area network (WLAN). Certain other wireless networking standards such as Bluetooth are available now. However, 802.11 standard is considered as the most effectual networking solution. Actually, the aim of the developers of this network interface was to connect computers through a local area network. However, it has now been changed and a wireless network interface is also used for Voice over Internet Protocol (VoIP) and internet access.

Based on the surveys conducted so far, it is clear that you can stay connected in your network for a long period each day. If you have a laptop with a wireless connection, you can walk around your office with your laptop without losing the connection. Nowadays, certain emergency services are transferring their confidential data through a wireless network. We can consider this as an evidence for the data security which is provided by wireless network. You can send and share data quickly through a wireless network. This is the main reason why businesses and people prefer this network interface for their data sharing. Another important fact regarding wireless networks is that you can connect to the network easily even from the regions which have poor telecom infrastructure.

Some of the main reasons which make the wireless network interface popular include:

i) Convenience as you can use this network interface at home, the office or anywhere else without hassle.
ii) WLANs are available anywhere in the world at an affordable cost.
iii) If you are moving to a new location, you can transfer the interface and install it at your new location easily.
iv) There is no need for an Ethernet cable to connect computers to each other.

For a business, one of the main advantages in setting up a wireless network is savings. You can access the changes in your business in a short period of time after installing the wireless network. There is no need to spend money on cables and other equipments. The cost of maintaining a wireless network is also less when compared to other network interfaces.

Nowadays, you can buy wireless routers at an affordable cost. Also having a wireless network can increase productivity and improve the working environment in your office.

One of the main drawbacks of this network interface is that it may cause health and environmental hazards. Recent researches reported that the constant use of wireless network interfaces may lead to memory loss, poor concentration, premature senility, nausea and even the hazardous disease named cancer. Some environmental hazards that may occur due the constant usage of this interface are also reported. These hazards occur due to electromagnetic radiation coming out of wireless networks.

How To Create A Wireless Computer Network

While living in a growing age of technology, having at least one computer in the home is just as common as having a refrigerator. Most homes today will have some sort of computer equipment for either personal use or business use. With today's wireless-equipped laptops, a wireless router and, if you need one, a wireless adapter card, even the technically-challenged can create a network in a heartbeat. This discussion isn't about Bluetooth technology, nor does it relate to Macs.

The First StepWorkstations, printers, and laptops need a wireless adapter card installed. They're easy to install--sometimes they're already built in. If so, your equipment will say it's wireless network capable. If not, remove the case from your desktop computer, follow the adapter card's directions, and you'll easily identify the slot the card fits into. On a laptop, the card slot is on one of the outside edges of the keyboard half. The card only fits in one way and installs in two seconds, no problem. Once the adapter is set into its slot, Windows' setup wizard steps you through installing the driver. You'll get the familiar message, "Windows found new hardware." Follow the prompts. The current wireless protocol is 802.11. Wireless cards costs between $20 and $130. They can be found at any computer store or online outlet. The $20 card should be adequate. For a few dollars, weak-kneed users can get a pro to install the card and drivers.

Buying Your Wireless Router Going in search of wireless routers at an office supply megastore, you'll find them from $39 and up. They come with 4 Ethernet ports plus a wireless access point. The Ethernet ports are sockets for setting up a "wired" network, but since you're going wireless, you won't use them. The wireless access point is the sort of radio thing on the router that talks to your computer to make the wireless connection. It doesn't require you to plug anything in. Spending extra money buys more speed between router and computer, but for home use, on a small network, it's not really relevant. Usually, a router that transfers data at 100 megabits per second is fast enough. The package will tell you the speed.

Safeguard Your Stuff By the way, an important fact about wireless routers is that they act as "firewalls." A firewall is software or hardware that prevents hackers from hacking into your system. The router puts an extra layer of security between you and them. Some people claim the protection is negligible but a techie friend of this writer, with every piece of security known to man, tried to hack my network to demonstrate how feeble the router's protection was. He said, "In 10 minutes, I'll have your data." Three hours later, cussing a blue streak, he threw in the towel. Good security.

Wireless - Continued To install the router, rely on manufacturer's directions. All routers are slightly different. For example, you'll plug your basic Netgear router into an electrical outlet, go back to your computer and navigate to Control Panel -- Network Connections. The wireless network connection icon should say you have succeeded and are connected. Your router is now talking to your computer. That's it. Next, choose enable encryption, which is a way to assigning a security key, like a password, to the network's access to keep neighbors or anyone else from using your network. Gurus encourage everyone to do this. It's not difficult to figure out. The manual directs you to type 192.168.0.1 into the address bar of Internet Explorer. Every user manual has a similar IP address (Web address) to an administrative program for each router. It's easy to follow menu selections on the page that comes us next. The help files are generally user-friendly and tech support is available by phone as well.

Hooking Up With your new network set up, you add security cameras, printers, shared storage or anything else that can accept an adapter card or comes with network capability. Each item added -- printer, camera, computer -- needs wireless capability or a card and each shows up on the network with a name you give it - like, "new photo printer" or "Joe's laptop." The best part of the whole set up is that the wireless signal goes through most walls, allowing you to work almost anywhere in your home, sans the yards of black spaghetti that used to connect you. Take your laptop n front of the fireplace. Recliner chair becomes your desk. Sip some hot buttered rum and be the envy of the neighborhood.
