#Contest Entry: Discuss Wireless Network by @anyiglobal || Zero to Infinity

Hello my fellow Networkers and lovers of Technology I greet you all. This is my entry on how wireless network works! I explicitly elaborate on Wireless Network in this content. Yeah, so let's get started!

First of all I will define what wireless network is!

What is a Wireless Network?
A wireless network refers to a network that creates use of frequency (RF) connections between nodes within the network. Wireless networks are a well-liked solution for homes, businesses, and telecommunications networks.

It is common for people to wonder “what may be a wireless network” because while they exist nearly everywhere people live and work, how they work is usually a mystery. Similarly, people often assume that each one wireless is Wi-Fi, and lots of would be surprised to get that the 2 aren't synonymous. Both use RF, but there are many various sorts of wireless networks across a variety of technologies (Bluetooth, ZigBee, LTE, 5G), while Wi-Fi is restricted to the wireless protocol defined by the Institute of Electrical and Electronic Engineers (IEEE) within the 802.11 specification and it’s amendments.

Wired vs. Wireless Network: what's the Difference?
At the foremost obvious, a wireless network keeps devices connected to a network while still allowing them the liberty to maneuver about, unencumbered by wires. A wired network, on the opposite hand, makes use of cables that connect devices to the network. These devices are often desktop or laptop computers but also can include scanners and point-of-sale machines.
There are more subtle technology differences that are available to play between wired and wireless. latest wired networks are now “full duplex”, meaning that they will be transmitting/receiving packets in both directions simultaneously. additionally , most wired networks have a fanatical cable that runs to every user device.
In a Wi-Fi network, the medium (the frequency getting used for the network) may be a shared resource, not only for the users of the network, but often for other technologies also (Wi-Fi operates in what are called ‘shared’ bands, where many various electronic devices are approved to operate). This has several implications: 1) unlike a wired network, wireless can’t both talk and listen at an equivalent time, it's “half duplex” 2) All users are sharing an equivalent space must alternate to speak 3) everyone can ‘hear’ all traffic happening . This has forced Wi-Fi networks to implement various security measures over the years to guard the confidentiality of data passed wirelessly.

Types of Wireless Connections
In addition to a LAN, there are a few of other kinds of common wireless networks: Personal Area Network (PAN), Metropolitan Area Network (MAN), and Wide Area Network (WAN).

LAN
A local-area network may be a network that exists at one site, like an office block . It are often wont to connect a spread of components, like computers, printers, and data storage devices. LANs contains components like switches, access points, routers, firewalls, and Ethernet cables to tie it all at once . Wi-Fi is that the most ordinarily known wireless LAN.

PAN
A personal-area network consists of a network centralized round the devices of one person during a single location. A PAN could have computers, phones, computer game consoles, or other peripheral devices. They are common inside homes and little office buildings. Bluetooth is that the most ordinarily known wireless PAN.

MAN
A metropolitan-area network may be a network that spans across a city, small geographic area , or business or college campus. One feature that differentiates a person from a LAN is its size. A LAN usually consists of a solitary building or area. A MAN can cover several square miles, counting on the requirements of the organization.
Large companies, for instance , may use a person if they need a spacious campus and wish to manage key components, like HVAC and electrical systems.

WAN
A wide-area network covers a really large area, like a whole city, state, or country. In fact, the internet is a WAN. Like the internet, a WAN can contain smaller networks, including LANs or MANs. Cellular services are the foremost commonly known wireless WANs.

The Components of a Wireless Network
Several components structure a wireless network’s topology:

• Clients: What we tend to consider because the user devices are typically called ‘clients’. because the reach of Wi-Fi has expanded, a spread of devices could also be using Wi-Fi to attach the network, including phones, tablets, laptops, desktops, and more. this provides users the power to maneuver about the world without sacrificing their bridge to the network. In some instances, mobility within an office, warehouse, or other work area is important . for instance , if employees need to use scanners to register packages thanks to be shipped, a wireless network provides the pliability they have to freely move about the warehouse.

• Access Point (AP): An access point (AP) consists of a Wi-Fi that's advertising a network name (known as a Service Set Identifier, or SSID). Users who hook up with this network will typically find their traffic bridged to alocal-area network (LAN) wired network (like Ethernet) for communication to the larger network or maybe the web .
