Adding WirelessNetworking

What is wireless networking? Although at first you might think of wireless networks in terms of simple LANs and desktop machines, in reality a wireless network can consist of almost any kind of computing machine and can extend over any area. Essentially, a wireless network transmits data along a certain frequency through the air rather than through a cable. Wireless networks include:

- LANs without fixed workstation locations

- Mobile networks, such as fleets of trucks connected via satellite

- Telecommuters who dial into their offices using wireless modems

The size of the network and the transmission medium are irrelevant to the definition of a wireless network. The main thing that most wireless networks have in common is a need for mobility. Few wireless networks evolve from traditional wired LANs more often, they stem from a unique need for networking components that are difficult or impossible to connect in any other way.

Much current wireless networking technology uses radio frequency (RF) signals to transmit data, but microwaves and infrared signals are also part of wireless technology.

Advantages and Disadvantages of Wireless Networking.

Like networking in general, wireless networking has things to recommend it, as well as definite detriments. Whether the pros outweigh the cons depends on your particular needs.

Advantages of Wireless Networking.

Most of the positive things about wireless networking stem directly from the lack of cabling to mess with.No cables potentially means the following:

- Networks in areas that are difficult or impossible to cable (for example, in less-developed countries or in buildings that are expensive or dangerous to cable)

- An easier network setup

- Printer sharing without a network

- Inter-office networking with no cabling "right-of-way" required

- Network access for those who can never be cabled (such as people with "virtual offices" in their cars)

- Modem use is possible without an outside telephone jack (a problem, for example, in hotels using switchboards)

In parts of the world where there either is little cable infrastructure or it has been damaged by war or environmental disaster, wireless communications can keep remote sites in touch with each other. How do you connect a remote mining site to the city office to discuss equipment needs? Or coordinate rescue efforts after an earthquake? In these cases, a cable infrastructure either never existed or no longer works. The only way to expeditiously share information in such circumstances might be a wireless network.
