Setting up wireless technology requires some understanding of how it works so that you may understand the limitations and requirements needed to use wireless technology. One of the major limits of wireless technology is the range. A typical wireless device like a router or access point will only have a range of about 300 feet. This could be much less if it has the interference of heavy building materials like stone, brick and steel. The other side of the problem is that your wireless device may extend the range into your neighbor's front room where your neighbor could use your network if you did not restrict the use of the network.
In this example, the black circle has access to several wireless networks. It is important to protect your internal network from access that you do not want to provide.
