Imagine being able to take your notebook computer to anywhere in your office and surf the Internet. This is no futuristic scenario. If you're looking to upgrade your network or set one up for the first time, this is your chance to explore the option of a wireless network.

Wireless networks offer two primary advantages over regular networks. The first is flexibility - with a wireless network, equipment like notebook computers and printers can be toted from office to office without a problem. The second is the ease with which it can be reconfigured. New employees can simply be added onto the network and your office can be rearranged without having to re-route all the wires.

Wireless networks, also known as WLANs, work by connecting devices via radio waves rather than wires. Each device that you want to be wireless, whether it's a desktop, notebook, or printer, needs a wireless adapter installed. You also need at least one access point, which is a small box with an antenna that acts as a hub for all the data being sent and received. Each access point allows 300 feet to 500 feet of roaming room, depending on how open your space is.

Before you rush out and buy a system, keep in mind that wireless networks are not yet perfect. Working on a wireless network can be slow, and network connections can be dropped. You might find yourself working on files at 10 percent of the speed you are used to with a regular network.

Interference can also cause bandwidth congestion, slowing down your network. This can come from other offices using WLANs, or even from a microwave oven in your office. Filing cabinets, walls, and other obstacles have also been known to compromise network speed. Multiple access points will help, but that can be a costly venture.

The technology is also still in its early stages, with several competing wireless technology standards. The Institute of Electrical and Electronics Engineers' (IEEE) standard 802.11b, which is also known as Wi-Fi, is prevailing as the choice for businesses.

Researchers recently found holes in the security encryption for 802.11b - meaning someone could get ahold of your data pretty easily. In the meantime, while researchers attempt to craft a solution (which is expected by the end of the year), sources of protection, such as firewalls and additional layers of encryption can help plug the security breach.

Prices for WLANs have been dropping considerably. An access point for a small office can cost as little as $300 - down from $1,000 last year. Similarly, the price tag for wireless access cards has also slipped from more than $1,000 last year for one card to $100 to $300 per card this year. By contrast, Ethernet cards cost about $50, but also require the often-costly installation of wires.

Given the recently dropping prices, WLANs are definitely an option with the potential for big benefits for small businesses. If you're shopping for a network solution, it may just be time to get out your wire cutters.
