Computers are connected through wired or wireless media. In wired media STP or UTP cables and devices like hub, switches, routers etc. are used. Now a days people are opting for wireless networking more than wired networking. In wireless networking radio waves and microwaves are used to attach computers. Wireless network also called Wi-Fi network. The first wireless card was 802.11b but the standard are upgraded day by day. In companies, universities, libraries, hotels, airports wireless network are more in demand and more feasible than the wired network. Telecommunication network is a bigger network in wireless networking eg. Mobile Phones. There are many wireless devices that are used like wireless Access Point, Wireless LAN Cards, Wireless Adapters, Wireless Routers etc. There are many types of wireless networking like Wireless PAN, Wireless LAN, Wireless MAN etc.
The wireless network has many advantages as compare to wired networking, there is no need to put cables across the walls of homes and offices, it helps maintaining the beauty and cost/time incurred on drilling/repairing the walls is saved. We also save cost incurred on network cables, it is less time consuming and requires less technical support, easy to set up than wired media. It is accessible anywhere within its range, hence you need not to find a network I/O to get connected, take your laptop within the range of the wi-fi network and access the internet or other resources.
The only problem of a wi-fi network is its limited range and larger networks are affected by weather as well. If you want to setup wi-fi for a large area say college campus etc. you have to add in more access points.
If you are planning to setup a wi-fi network at your home or office, you must address the security issues as someone may intrude into your network and access your valuable information or may send emails using your IP. In the recent incidences, terrorists used the Wi-Fi network of neighbors to communicate with each other and sent threatening emails to people. Hence, ensure that your Wi-Fi is fully secured and nobody else is using it except you.
You can protect your network with firewalls, proxy, VPN and WEP key etc. In WEP (Wired Equivalent Privacy) we give a security code that secures our network and unauthorized person can not access the network. WEP comes with 64bit, 128bit , WPA-PSK, WPA?TKIP security features. For better security, keep changing your WEP key and administrator password, router password regularly, filter out the MAC address and use firewalls at every computer in a network and lock all the folders and make access lists. Access list provided extra level security while giving instructions to routers and filter the MAC addresses. Switch off the routers and other devices when not in use. But the above securities measures can not be implemented in the public areas like libraries, hotels, airports etc.
More and more electronic devices are wireless. From high-tech personal digital assistants (PDAs) to cutting-edge laptops and more, these wireless wonders are becoming a fixture for business and personal uses. Wireless networking solutions allow people to easily exchange information between these devices and are becoming essential to productivity and to conducting business. Still, there are many who find that establishing a Wi Fi networking connection of their own can be costly and sometimes confusing.
One way to get around the expense and hassle of putting in your own wireless network is to piggyback on the Wi Fi connections that are already in place. Being able to find public wireless Wi Fi hotspot connections that you can tap into also enables travelers to stay connected and in touch no matter where they happen to be. This makes it easy for business people to stay productive even when they need to be on the road taking care of business.
Locating the existence of the Wi Fi networking wireless mobile hotspots is the first step in being able to leverage these free Wi Fi networks and it opens up the possibility of enjoying internet access from just about anywhere. This of course has the potential to enhance both business and personal communications and makes ecommerce easy.
One of the ways to locate Wi Fi connections is to use a device that "sniffs out" the Wi Fi hotspot signals. These Wi Fi sniffers are a relatively new tool that simplifies the task of finding the available hotspots and can be the fastest way to help you find a Wi Fi access signal when you need it the most.
These days, all of the major airports and most hotels provide access to Wi Fi connections for both business and leisure travelers. In many municipalities there are even Wi Fi networks that are often accessible to people who want to do their work or their studies from a peaceful park, a cozy coffee house or busy shopping center. Mobile Wi Fi wireless antennas provide people on the go, such as truck drivers, RV vacationers and others, to have continual wireless mobile access to the internet. This means that they won't need to leave their laptops or personal digital assistants at home, but can put them to use through Wi Fi connections to stay in touch with family, friends or their company.
