In an attempt to secure his 802.11b wireless network, Bob decides to use strategic antenna positioning. He places the antenna for the access point near the center of the building. For those access points near the outer edge of the building he uses semi-directional antennas that face towards the buildings center. There is a large parking lot and outlying filed surrounding the building that extends out half a mile around the building. Bob figures that with this and his placement of antennas, his wireless network will be safe from attack.
