A wireless network is a computer network of any kind that is wireless and is often connected with a telecommunications network that has interconnections amid nodes that are applied without using wires. These wireless networks are typically applied with some sort of data transmission system which utilizes electromagnetic waves for the carrier and this application typically occurs at the physical “layer” or level of the network.
Wireless Connection Types
1. The Wireless PAN, known as WPAN, has a role of interconnecting devices that are within a small area and is typically within a person’s reach. An example of this would be the Bluetooth which is a WPAN used for interconnections of a laptop with a headset. WPAN are also supported by ZigBee. Some others that are getting popular are Wi-Fi PANs because vendors have begun integrating Wi-Fi in devices consumers use.
2. The Wireless LAN, known as WLAN, has a role of linking two or more devices by using wireless distribution methods (usually OFDM radio or spread spectrum), and typically supplies a connection to the wider internet through an access point. This allows a user the capability of moving around inside local coverage regions and not loose network connections. Some examples include Wi-Fi and Fixed Wireless Data.
3. Wireless MAN, known as Wireless Metropolitan Area Networks, are wireless networks that have the role of connecting numerous Wireless LANs. An example of a Wireless MAN includes WiMAX.
4. The Wireless WAN, known as wireless wide, are wireless networks that cover an outdoor area that is large in size. They can be used as public internet systems of access or to connect a business branch office. These systems usually contain wireless bridging relays, access points, and base station gateways. There are additional configurations which are mesh systems in which every access point serves as a relay.
