Types of the wireless network: The wireless network is a network that is not connected by wired or any physical communication medium. In today’s life wireless network is too common we are using it almost everywhere. There are so many types of wireless networks. We are using it like a mobile, Wifi, TV, Radio, satellite Communication and so on. They use radio waves for communication between the network nodes. So in this article, we are going to see Types of wireless networks.

Advantages of the wireless network.

  • It’s too easy to install and set up a wireless network as compared to a wired network.
  • It saves additional wire cost which needs to establish a wired Lan connection.
  • It helps you to keep your desk free from a mess of wires.
  • You can connect new devices easily without adding any extra wire such as Tv, Laptop, Sound system, Cameras E.T.C.
  • It increases the mobility of network devices which is connected to the system since the devices need not be connected to each other.
  • Accessing network devices from any location is easy. You can easily change the location of any device within wifi range.

(PAN) Personal area network.

A personal area network can be defended as a computer network that connects devices within the renege of person to person or in less area.

PAN provides a network range within 10 meters (33 feet) which is quite a small area. in PAN networks devices contain such as tablets, computers, printers, phones, PDAs, speakers, remote, video game consoles, etc.

The Personal area network PAN is developed in M.I.T. Media Lab by Thomas Zimmerman and other researchers

Types of Personal Area Network (PAN) :

There are two types of Personal Area Network Depending upon there connection such as Wireless Pan or Wired PAN

  1. Wireless PAN – Wireless Personal Area Network uses signals to communicate or transfer data from one device to another device such as Bluetooth, ZigBee, infrared. Wireless PAN is used every ware such as remote, toys, sounds, headphones, TV, Laptop, mobile, etc. the devices which work in a small area.
  2. Wired PAN – Wired Pan can be defined as the networks which are established using cables in a small area such as (USB).

Example of PAN:

  1. Home Office Network: In-Home Office setup the separate small network which is not connected to the internet is called Home Office Network such as a printer, keyboard, mouse, PDA, Laptop, Desktop connected to each other using wired or wireless medium. This network works as a separate body of network in-home or office.

2. Body Area Network: while walking around a person carries various devices with him such as headphones, Bluetooth, Smartwatch which is connected to mobile or other communication devices which he carried is Body Area Network.

Types of wireless network

(LAN) Local area network.

LAN can be defined as a computer network that contains cables, routers, switches, access points that enable devices. To connect internal servers or web servers within campus, hospitals, schools, buildings, or home network. and connected to other LANs via a wide Area Network (WAN).

Devices connected to LAN are typically computers, laptops, workstations, which can share files and can be accessed by each other for communication over single internet connection.

WLAN (Wireless Local Area Network)

WLAN stands for “Wireless local area network” These networks allow devices to connect and communicate wirelessly. A traditional wired LAN, in which devices connected to it comunicate through Etharnet cables, such as devices on WLAN communicate using WI-FI.

Basically, the behavior or work or LAN or WLAN is the same but it looks different. the only difference is the LAN uses cables to communicate between devices or WLAN uses signals to communicate with devices.

in these network devices are typically added or configured using DFCP.

In LAN data is transferred over physical cables in series of Ethernet packets. or in WLAN, data is transmitted through the air using one of the IEEE 802.11 protocols.

But WLAN should not be confused with WI-FI, there are some semantic differences in These. Where “Wi-Fi connection” refers to a given wireless connection that a device uses, Or the WLAN is the network itself, which is different.

Types of wireless network

(MAN)
Metropolitan area network

Metropolitan area network can be defined as the network which interconnects the computer users or wireless gadgets or resources to the network.

it connects the resources within the size of the metropolitan area Such as town, city.

In simple language, we can say that the metropolitan area network is a network of LAN as we see the LAN is the connection of multiple computers or devices interconnected in a smaller area by using LAN.

Or interconnection of LAN within the larger area such a city we can build a metropolitan area network MAN. It is nothing but an interconnection of LAN within the area which is the size of the city.

History of Metropolitan area network.

LAN is very well established in 1999 for communication in buildings offices or institutes. But the limitation of LAN is it only works in small areas such as one building. So for communication at that time, people in the city probably relied on the public switched telephone network. Which is used for voice communication within the city.

So all the businesses mainly relied on that network. But when the telephone network was able to support data transfer through it as a packet -transfer then people start to use it for the exchange of data. But that network already has a heavy load or demand for circuit-switched voice. Telephone lines are not made for transfer such huge files or data as LAN does.

So to solve that problem they connected office buildings using single-mode optic fiber lines. Such as dark fiber or then telephone companies start to provide these services within subscriber packages. So the load of the telephone line is reduced or the speed of transferring data through these networks also increased.

and they start to connect the whole city with these networks or all the city become a big interconnected network called a (MAN) Metropolitan area network.

Types of wireless network

(WAN)
Wide area network

WAN Wide Area Network We know this network as the Internet. WAN is a worldwide network that is mainly formed to connect the world together for sharing information transfer data or communication.

MAN network provides connection within the limited area it has its limitations. or forming MAN network worldwide is not possible due to geographic conditions or the cost it needs to be established.

IT is a telecommunication network that is extended over a large geographic area for the purpose of a computer network or sharing information. it is often established with leased telecommunication circuits.

It is built by internet service providers to provide a connection from an organization’s LAN to the Internet WAN. WAN’s are often built by using a leased line. where each leased line end has a router connected to it.

How did WAN start?

The U.S. Air Force in the late 1950s created the first WAN network to interconnect sites in the Semi-Automatic Ground Environment (SAGE) radar defense system. They build it by using dedicated phone lines, Telephones, or Modems linked to the sites together.

The Advanced Research Projects Agency Network (ARPANET) is the foundation of the IP based internet. the first wide-area packet-switching network with distributed control & it is the first network to implement TCP/IP protocol suite.

What is a WAN router?

A WAN router is a device that routes data packets between WAN locations, which is giving enterprise access to the carrier network.

Several WAN protocols have been developed over time, including Packet over SONET/SDH (PoS), ATM, Multiprotocol Label Switching (MPLS), and Frame Relay.

Types of WAN technologies

  • Packet switching
  • TCP/IP protocol suite
