Comparing WLANs with Ethernet LANs

WLAN Concept 

A Wireless LAN connects mobile users to a LAN with a wireless connection. It uses high-speed radio waves to initiate communication between the connected devices. Nowadays PC users mostly use laptops. The laptop users may need to connect to a network whenever they are at home or at work They also need to connect to the internet very often. This has increased the growth of wireless LANs. 

Comparing WLANs with Ethernet LANs

Ethernet LANs and WLANs are similar in many aspects. Both the networks allow devices to communicate with each other.

WLANs 

1. The IEEE standard for WLAN is IEEE 802.11.

2. WLANs use high energy radio waves to transmit data.

3. Radio waves travel through space; hence a physical connection is not required between devices that are connected to WLANs. 

4.. WLAN uses half-duplex (HDX) mechanism for communication.
5. WLANs suffer more interference since the matter (walls, metals and other obstructions) in the space come in the way of radio waves that travel through space.
6. WLANs use CSMA/CA ((Carrier Sense Multiple Access/Collision Avoidance) to avoid collisions in the network. 

Ethernet LANs 

1. The IEEE standard for Ethernet LAN is IEEE 802.3. 

2. Ethernet LANs use electric signals to transmit data. 

3. Electric signals flow over cables; hence a wired connection
is required between devices that are connected to Ethernet LANs. 

4. Ethernet supports Full-duplex (FDX) mechanism for communication when a switch connects through a single device rather than hub.
5. LANs suffer less interference since the electric signals travel through cables. 

6. LANs use CSMA/CD (Carrier Sense Multiple Access/ Collision Detection) to detect collisions in the network.
