Compare and contrast wired and wireless LANs. What unique concerns must be addressed by the designer of a wireless networks.
LAN is a local Area Network and a computer network covering a small physical area, like a home, office, restaurant or small group of buildings, such as a school, a college or an airport. Although a LAN can be used as an isolated network to connect computers in an organization for the sole purpose of sharing resources, most LANs today are also linked to a wide area network or the Internet. A LAN can be one of two types: wired or wireless. A wired LAN requires Ethernet cable to physically connect all computers on the network to a main device called a switch. Below is an example of wired LAN.
1.1 Wired Local Area Network
WLAN is a wireless local area network links devices via a wireless distribution method and usually provides a connection through an access point to the wider internet. This gives users the mobility to move around within a local coverage area and still be connected to the network. A wireless LAN uses radio waves to communicate, eliminating the need for wires. Therefore, the hardware used in a LAN should all be of either the wireless or wired type.
1.2 Wireless Local Area Network
Wireless networking hardware requires the use of underlying technology that deals with radio frequencies as well as data transmission. The most widely used standard is 802.11 produced by the Institute of Electrical and Electronic Engineers (IEEE). This is a standard defining all aspects of Radio Frequency wireless networking.
A Mixed Wireless Network is one with both wired and wireless connections. In a Mixed Wireless Network, some devices are directly connected via Ethernet cables, while other devices, including Desktops, Laptops connect wirelessly via Wi-Fi.

Mixed Wireless Networks are ideal if you have one or more desktops within Ethernet cable range of your
