The purpose of reasonable protection of wireless access points is to isolate the wireless network from outsiders who are not authorized to use the service. It is often easier said than done. In terms of security, wireless networks are often more difficult to protect than fixed wired networks because of the limited number of fixed physical access points in the wired network and the use of wireless networks at any point in the antenna's radiation range. In spite of its difficulties, the rational protection of wireless network system is the key to avoid serious security problems. To maximize these vulnerabilities, ensure that network personnel take six measures to protect the wireless network. Planning antenna ...
