Guide to Setting Up a Wireless Network
Wireless networking is a technology that enables the cabling that connects each computer to the network to be replaced by a specially coded wireless signal. When fitted with a wireless network card, a computer can exchange data with other similarly equipped computers nearby without the need to be plugged into a network point, forming a wireless network. Since the wireless network uses the same protocols and addressing schemes as a wired network, the two types of network can be freely mixed.
Like a wired network, a wireless network is neutral to the operating systems used by the computers on the network. Whether you are a PC user, a Mac user or a Linux user you will be able to wireless network if you install the appropriate wireless card in your computer or laptop.
In the last two or three years, low cost wireless components have produced a number of ways of connecting computers together wirelessly. These networks are growing in popularity with many organisations because they offer low purchase costs, almost no installation costs and they allow wireless equipped computers to be freely moved around the room, the building or even outside.
Wireless networks can be easily assembled with only basic knowledge of computers and networking. Most wireless components are built with their own software or firmware that will make them work “out of the box”, so for many users it has simply been a matter of install and go. However, this deceptive ease of use hides a number of pitfalls to do with differing standards, physical limitations with wireless signals, and security issues. These pitfalls can make setting up or extending a wireless network a nightmare if the issues are not considered before the components are purchased.
