WMAN network  What is it and what is it for? Examples ▷ 2020

Wireless networks They have become one of the most important elements of today. They are known to all, but only very few really know What are they and what is their function? This is how these networks have become essential in the life of the human being, being used daily by the majority of users.

As usual, wireless networks were previously used only in the military or scientific academies, but as time has passed, their use has expanded, becoming used in shopping malls, industries, clinics, at home, work, among many other sites.

Due to the great amplitude that was achieved, they had to create different types of networks where each of them was adapted for a specific need. This is how here we will explain a little more about the WMAN network and its operation.

What is a WMAN network and what are they for in computing?

What is a WMAN network and what are they for in computing?

This type of network allows users to establish wireless connections between different locations within the same metropolitan area. They stand out for having a range of tens of kilometers. Usually connections can be made between office buildings in a city or on university campuses.

One of its main advantages is that it does not require a high investment cost what it is for its installation through copper or fiber cables, as well as the rental of lines. Thus, WMAN usually uses infrared light or radio waves to transmit the data from point A to point B.

In this way, this type of network usually has a radius of action greater than WLAN networks, thus spanning tens of kilometers to signal transmission, becoming enough to cover a entire population.

Thus, WMAN mainly serves to interconnect the WLAN networks with each other. Also, use WiMAX technology where its use is increasing and reaching hard-to-reach areas or rural areas where before they did not arrive internet connections.

What are the main characteristics of a WMAN network?

This type of network is mainly characterized by be the sum of many interconnected local area networks. What is also known to many as a wireless local loop.

He himself has become a wireless communication standard which is based on the IEEE 802.16 standard, being a protocol very similar to WiFi, but that has a greater coverage range and bandwidth.

With this in mind, here we show you the main characteristics of this network:

  • Your coverage can extend up to maximum of 50 km.
  • According the frequency range used for transmission can be radio waves or infrared.
  • In the case of infrared, they must be completely aligned on a surface, and they go from 300 GHz to 384 THz.
  • It also has a communication system such as the LMDS “Local Multipoint Distribution Service”.
  • Its technology is based on WiMAX “Worldwide Interoperability for Microwave Access”.
  • It serves to provide connectivity of portable and mobile broadband, anywhere and anytime.
  • It offers the possibility of power access a wireless alternative to traditional wired systems. In this way, it allows free broadband access.

WMAN vs MAN How are they different and which is the better type of network?

Wireless networks they have become one of the most important factors today. That is why the creation of a large number of networks has been developed to carry out different functions and thus achieve better results and greater signal ranges. In accordance with all this, here we are going to explain the difference between what is a WMAN network and a MAN network.

WMAN network

  • The WMAN network or wireless Metropolitan network is a MAN wireless version.
  • It usually has a greater range of tens of kilometers compared to MAN.
  • It uses techniques that are based on the WiMAX communications standard.
  • It is able to provide a data transmission across an entire population.

MAN network

  • The MAN network or Metropolitan Area Network has been designed to be used for data transmission in towns or cities.
  • They have a smaller geographic reach than wide area networks like WMAN.
  • They are characterized by having very good speed connections where they use fiber optic cables.
  • Has a much lower latency and error rate than WMAN networks.
  • Is very stable and resistant radio interference.

What are the most used topologies for this type of wireless networks?

Currently there are different types of topology in wireless networks, these being of different forms and each one of them with a specific objective. Thus, the topology is responsible for describing the way in which the data is converted into a raster format And the way in that electrical pulses are transmitted through the communication medium. Therefore, here we show you each of the most used topologies in networks.

Mesh Topology

Also known as the mesh network topology, where each of nodes is connected to all other nodes. This allows messages to be carried from one node to another by different paths and in a very simple way.

In the event that the mesh network is fully connected, this cannot have any communication break. This is because each of the servers have your own connections to all other servers of the system.

Ring Topology

Is ring network indicates that each of the stations have only one inlet and one outlet connection. Therefore, each of these stations will have a receiver and a transmitter which also does the function of translator, and in turn will pass the information to the next station.

In this case, communication occurs through the passage of a token or token, which can be defined as a kind of element that collects all the information and then delivers it in packages. This serves to avoid what is loss of information and collisions.

Double ring topology

The double ring topology is similar to the ring one, but this has the difference that it has a second ring connecting the same devices. That is, it allows increase network flexibility and reliability, where each of the network devices is part of two independent ring topologies.

Therefore, this topology acts as if they were two independent rings, but only one is used at a time.

Star topology

The star network indicates stations are connected directly to a central point in the system. Therefore, all existing communications have to go through it. In this case the devices are not found connected to each other, neither allows a lot of information traffic simultaneously, this in order to avoid collisions.

Bus Topology

This Bus network is characterized by having only one communication channel which is called bus, backbone or trunk and which connects to different devices. This makes all devices have to share the same channel to communicate with each other.

Tree Topology

We finally found tree topology, which indicates that the nodes are located in the form of a tree. This looks very similar to what a series of interconnected star networks, but in this case they do not have a central node. But if they have a trunk node which is frequently occupied by a switch or hub, from which the other nodes branch.

Examples of wireless metropolitan area networks

Wireless networks are characterized mainly by operating as any form of communication established, either through reciprocity of senders and receivers through a physical channel or through coordinated interaction.

Depending on the functionality of these elements, the performance of the network will mainly depend. With this in mind, here are some examples of metropolitan area wireless networks.

LAN networks

LAN networks

  • Is a computer network or computer network that are connected to each other by physical devices for sending and receiving information.
  • Is a net domestic that anyone can install in their home to cover devices such as computers and mobile phones.
  • It is also considered as a internal office network where this type of network is often implemented so that all workers’ computers can communicate. This also allows them to have shared access to computers such as printers, sharing portfolios among other elements.
  • In almost every city in the world it is used to provide free Internet to the public. This is done through short-range wireless hotspots, typically be no greater than 10 meters.
  • They are also frequently used in the small commercial stores, where they can bring Internet to your computers and the customers who come to the store.

WAN networks

WAN networks

  • National banking networks usually use this type of network, since from it they can manage a very wide network and with connections to other banks, even if they are abroad.
  • The Internet is another clear example of what these are WAN networks, which is capable of communicating technological devices that are in enormous distances, even between different countries or continents.
  • It is also used by military satellite networks, since it allows them to have a very wide communication to which they add the satellites, ships, planes, domestic transport vehicles, among many others.
  • The big ones business franchises of the world they also use WAN networks. This allows you to have your workers informed and communicated, being able to exchange information and data between each of the branches.

MAN networks

MAN networks

  • They are generally used by government institutions of each of the countries, it offers greater security which makes it ideal for share critical and private data. These are usually interconnected through a optical fiber that allows them to be on the other side of the city and not lose any type of information.
  • Used mostly by companies that sell local internet access, also known as ISP or Internet Service Provider. This service is offered through MAN networks which are in charge of managing each of particular LAN networks.
  • Today it is also applied by a large number of businesses and shops that are interconnected in the same University City, and which in turn are separated by a wide distance.
