Increased use of laptop computers within organisations, and the necessity for worker mobility have fuelled the demand for wireless networks. Until recently, wireless technology was a patchwork of incompatible systems from a variety of vendors. The technology was slow, expensive and reserved for mobile situations or hostile environments where cabling was impractical or impossible. With the maturing of industry standards and the deployment of lightweight wireless networking hardware across a broad market section, wireless technology has come of age. |

| What about security? | |
Wireless communications obviously provide potential security issues, as an intruder does not need physical access to the traditional wired network in order to gain access to data communications. However, 802.11 wireless communications cannot be received --much less decoded-- by simple scanners, short wave receivers etc. However, to protect against more sophsticated potential security issues, 802.11 wireless communications have a function called WEP (Wired Equivalent Privacy), a form of encryption which provides privacy comparable to that of a traditional wired network. |

In addition however, there are a number of inexpensive security solutions which can also be bolted on to the wireless solution as well as incorporating your existing virtual private network (VPN). |
