Design an Outdoor Wireless Network You are a network technician for a small corporate network. You need to create a network connection between two buildings. You've decided that a wireless connection between the two buildings is the best solution. Employees have complained about the wireless connection on both buildings' patios. You conducted a wireless site survey and found that the wireless signal is very poor on both patios. In this lab, your task is to complete the following: Install the proper antenna on the roof of both buildings to provide a high-speed wireless connection between them. Use the wireless survey exhibit to identify weak signal areas and determine which type of antenna to use with the WAP. Install the appropriate WAP on the roof of each building. Attach the antenna that will provide adequate coverage to only the problem area.

Install an antenna on each building's roof to provide a high-speed wireless connection. On the Shelf, expand High-gain Antennas. Drag the High-gain Antenna (Directional) to the installation area on Building A's roof. You use a high-gain directional antenna for the connection between the buildings to provide a very strong, concentrated signal in only one direction. Using a high-gain omnidirectional antenna will broadcast the signal in all directions for a very long distance, introducing a security vulnerability. Drag the remaining High-gain Antenna (Directional) to the installation area on Building B's roof. Install a WAP on each building's roof. On the Shelf, expand Wireless Access Points. Drag the Wireless Access Point (Outdoor) to the installation area on Building A's roof. Because you need to provide coverage to only the patio areas, the best antenna choice is a directional antenna. Outdoor WAPs are designed to withstand outdoor conditions, such as heat, cold, and rain. Drag the remaining Wireless Access Point (Outdoor) to the installation area on Building B's roof. Attach both antennae to provide adequate coverage. On the Shelf, expand WAP Antennas. Drag the WAP Antenna (Directional) to one of the installed outdoor WAPs. Drag the remaining WAP Antenna (Directional) to the other installed outdoor WAP.
