Wireless Networks
Computer networks that are not connected by cables are called wireless networks. They generally use radio waves for communication between the network nodes. They allow devices to be connected to the network while roaming around within the network coverage.
Types of Wireless Networks
- Wireless LANs Connects two or more network devices using wireless distribution techniques.
- Wireless MANs Connects two or more wireless LANs spreading over a metropolitan area.
- Wireless WANs Connects large areas comprising LANs, MANs and personal networks.
Advantages of Wireless Networks
- It provides clutter-free desks due to the absence of wires and cables.
- It increases the mobility of network devices connected to the system since the devices need not be connected to each other.
- Accessing network devices from any location within the network coverage or Wi-Fi hotspot becomes convenient since laying out cables is not needed.
- Installation and setup of wireless networks are easier.
- New devices can be easily connected to the existing setup since they neednt be wired to the present equipment. Also, the number of equipment that can be added or removed to the system can vary considerably since they are not limited by the cable capacity. This makes wireless networks very scalable.
- Wireless networks require very limited or no wires. Thus, it reduces the equipment and setup costs.
Examples of wireless networks
- Mobile phone networks
- Wireless sensor networks
- Satellite communication networks
- Terrestrial microwave networks
