Wireless Networks
Good day Steemians!
It is another blessed day to which I will like to write on wireless networks. And I hope you will find it beneficial.
Over the last few years, the world has become increasingly mobile. The world's traditional networking methods have failed to meet the problems posed by our modern collective lifestyle. When users must connect to a network via physical wires, their mobility is severely limited.
The University of Hawaii established the first professional wireless network, known as ALOHAnet, in 1969, and it went online in June 1971. The WaveLAN product line, created by NCR in 1986, was the first commercial wireless network.
Wireless networking is a means for avoiding the costly process of putting wires into a building or as a connection between various equipment locations in residences, telecommunications networks, and corporate installations. Radio communication is commonly used to establish and operate commercial telecommunications networks. The physical layer (layer) of the OSI model network structure is where this implementation takes place.
Cell phones, wireless local area networks (WLANs), wireless sensor networks, satellite communication networks, and terrestrial microwave networks are all examples of wireless networks.
Types of Wireless Networks
• Wireless PAN
WPANs (wireless personal area networks) connect devices in a small area that is usually within reach of a person. In order to connect a headset to a laptop, a WPAN is created using both Bluetooth radio and invisible infrared light. WPAN applications are supported by ZigBee. Wi-Fi PANs have become easier to set up and configure thanks to Intel's "My WiFi" and Windows 7's "virtual Wi-Fi" features.
• Wireless LAN
A wireless local area network (WLAN) uses a wireless distribution mechanism to connect two or more devices over a short distance, typically giving internet access through an access point. Users may be able to roam around inside a limited coverage area while still being connected to the network if spread-spectrum or OFDM technologies are used.
Wi-Fi is a brand name for products that use the IEEE 802.11 WLAN standards. Fixed wireless technology uses dedicated microwave or modified laser light beams over line of sight pathways to create point-to-point links between computers or networks at two different sites. It's commonly used in cities to connect networks in two or more buildings without having to create a cable connection. A wireless router or the private hotspot capabilities of another mobile device can be used to connect to Wi-Fi using a mobile smartphone.
• Wireless ad hoc network
A wireless ad hoc network (WANET), also known as a wireless mesh network or a mobile ad hoc network (MANET), is a wireless network made up of radio nodes that are organized in a mesh topology. Each node executes routing and forwards messages on behalf of the other nodes. Ad hoc networks have the ability to "self-heal," rerouting traffic around a node that has lost power. A variety of network layer protocols, such as Distance Sequenced Distance Vector routing, Associativity-Based Routing, Ad hoc on-demand Distance Vector routing, and Dynamic source routing, are required to implement ad hoc mobile networks.
• Wireless MAN
Wireless metropolitan area networks (WMANs) are a type of wireless network that connects many wireless local area networks (WLANs).
• Wireless LAN (WLAN)
WWANs (wireless wide area networks) are wireless networks that commonly cover huge areas, such as between cities or between cities and their suburbs. These networks can be used to connect business branch offices or to provide public Internet access. Point-to-point microwave lines using parabolic dishes on the 2.4 GHz and 5.8 GHz bands, rather than omnidirectional antennas, are used to connect access points in larger networks.
• Cellular Network
A cellular network, also known as a mobile network, is a radio network that is divided into cells and supplied by at least one fixed-location transceiver, also known as a cell site or base station. To avoid interference in a cellular network, each cell typically employs a distinct set of radio frequencies than all of its immediate neighbors.
Originally designed for cell phones, cellular telephone networks now commonly transport data in addition to voice calls, thanks to the rise of smartphones.
• Global Network
A global area network connects a large number of wireless LANs, satellite coverage zones, and other locations to support mobile communications. The transfer of user communications from one local coverage area to the next is a major difficulty in mobile communications.
• Space Network
Space networks are networks that allow spacecraft to communicate with one another, mainly in the neighborhood of the Earth. NASA's Space Network is an example of this.
USES
Cell phones, which are a part of everyday wireless networks and allow for convenient personal communication, are one example of utilization. Intercontinental network systems, for example, communicate across the globe via radio satellites. Wireless networks are often used by emergency services such as the police. Individuals and enterprises, whether in a tiny office building or across the globe, use wireless networks to send and exchange data quickly.
