Root
ABC company has contracted you to install a wireless LAN in their facilities. They inform you that there is a warehouse approximately 200 feet from the main building and that there are no Ethernet wires run to the warehouse. Which of the following technologies will you most likely use to provide wireless network access to the remote warehouse?
