Going Wireless at Work
Most businesses now have a broadband Internet connection with more than one PC connected in a network arrangement. This involves a lot of messy cabling and, until recently, the only option was to spend a small fortune on a wireless network. However, going wireless these days will cost you less than you think - and do a lot to free up your workplace.
Wireless networks aren't really complicated. They work just like a cabled network but their communications are sent via a wireless signal similar to that of a cordless telephone. All computers on the network can share the same Internet access point, and as long as they're within the area served by the network, can share equipment such as printers and other hardware devices.
How wireless networks operate
At the center of the network is a 'router' or 'hub' that transmits a signal to the equipment forming part of the network. One computer is always used with the router and stays on whenever the network is in use. The router connects to the Internet and removes the need to log on every time you want Internet access from a computer in the network. You can stay with your current Internet service provider (ISP) but check that they will support wireless networks when problems occur.
There are currently three wireless standards in use around the world, A, B and G. As progress has been made in wireless networking technology the speed and security of operating standards has been improved, although it's possible that the current 'G' standard may be superseded at some time in the future.
Why you'd enjoy going wireless
The basic benefit naturally, is that you do away with all the cable connections in your office. You can move your computers and printers around without having to re-cable every time. You also don't have to worry about hiding cables or ensuring that nobody trips over wiring between pieces of equipment.
There's no need for users of notebook computers to have docking stations. Once they are within the network coverage area they're wirelessly connected just like any other PC. This can be a big benefit for businesses with frequent visits from members of their field sales team. It's also much easier to add a new PC or notebook to the network. Once their wireless connection has been configured its part of the system.
Things you need to consider before going wireless
The wireless signal is limited in its range, depending on such things as the power of the signal source (the router), how far the signal has to travel, and what it has to travel through.
Things like walls and filing cabinets reduce the strength of the signal and therefore the distance over which it can effectively be used. Trying to operate a wireless network between two floors in a modern office building can also be a problem. To some extent these problems can be overcome with signal boosters, although these devices have their limitations too.
Your network can also suffer from interference caused by other radio signal-emitting devices, including cordless phones, cellular phones and 2-way voice communications systems. It's always best to use the services of an expert when setting up your network so it will do what you want it to do and work at optimum levels. |
