WMAN network: What is it, what is it for and how does this type of wireless network work?

wireless networks They have become one of the most important elements of today. The same is known by all, but only very few really know what are they and what is their operation? 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 They were previously used only in military or scientific academiesbut as time has passed its use has been extended, coming to be 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?

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. Connections can usually 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 for what it is its installation through copper or fiber cables, as well as the rental of the lines. Thus, WMAN typically use 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 covering tens of kilometers to signal transmissionbecoming enough to cover a entire population.

Thus, WMAN It mainly serves to interconnect WLAN networks with each other. Also, use WiMAX technology where its use is increasing and reaching hard-to-reach 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 by 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 WiFibut it has a greater range of coverage and bandwidth.

Taking this into account, here we show you the main characteristics of this network:

• Your coverage can be extended up to maximum of 50 km.
• According to the frequency range used for transmission can be of radio or infrared waves.
• 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 like the LMDS “Local Multipoint Distribution Service”.
• Its technology is based on WiMAX “Worldwide Interoperability for Microwave Access”.
• It is used to provide connectivity portable and mobile broadband, anywhere and anytime.
• It offers the possibility of 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 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. According to 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 wireless version of MAN.
• usually has a increased range range of tens of kilometers compared to MAN.
• It uses techniques that are based on the WiMAX communications standard.
• is able to provide a transmission of data in 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 that wide-area networks such as 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 to radio interference.

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

Currently there are different types of topology in wireless networks, being these of different forms and each one of them with a specific objective. Thus, topology deals with describing how 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 mesh network topologywhere 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 case that the mesh network is fully connectedthis one cannot have any interruption in communication. This is because each of the servers have your own connections to all other servers of the system.

Ring Topology

Is ring net indicates that each of the stations have a single input connection and one output connection. Therefore, each of these stations will have a receiver and a transmitter which also acts as translatorand in turn will pass the information to the next station.

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

Double ring topology

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

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

star topology

the star network indicates that the stations are directly connected 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, does not allow either a lot of information traffic simultaneously, this in order to avoid collisions.

Bus Topology

This Bus network is characterized by having a single communication channel which is called bus, backbone or trunk and which connects to different devices. This causes all devices to 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 hub node. But if they have a trunk node which is frequently occupied by a switch or hubfrom which the other nodes branch.

Examples of wireless metropolitan area networks

Wireless networks are mainly characterized by operating as any form of communication establishedeither through the reciprocity of transmitters and receivers through a physical channel or through coordinated interaction.

Depending on the functionality of these elements, the performance of the network will depend mainly. With this in mind, here are some examples of wireless metropolitan area 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, share work folders among other items.
• In almost all the cities of the world they use it to provide free internet to the public. This is done through low-range wireless hotspots, typically be no more than 10 meters.
• They are also frequently used in small commercial stores, where they can bring internet to your computers and customers arriving at the store.

WAN networks

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

MAN Networks

• They are generally used by government institutions of each of the countries, it offers greater security which makes it ideal for share sensitive 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 information.
• Mostly used by companies that sell local internet accessalso known as ISP or Internet Service Provider. This service is offered through MAN networks which are responsible for managing each of private LAN networks.
• Today it is also applied by a large number of businesses and shops that are interconnected in the same University Cityand which in turn are separated by a wide distance.
