What is Campus Area Network (CAN) and How does it Work
Basic Networking

Campus Area Network (CAN) With Example

Campus Area Network was shortly called the CAN. Office, school, any area that presented at a limited distance is called the campus. The Providing of the network at a particular location is called a Campus Area Network. Now How the Campus Area Network is get connected? We cannot connect through Wi-Fi. The Campus area network is considered as more than the local area network, it is the collection of multiple buildings or houses at a particular within the particular area.

Several Local area networks can be connected through a switch or a router that connects through the single network area. The Campus area network has a maximum length of 40 meters.

Many educational institutions, campus universities, and all corporate and office buildings have come under the campus area network.

Let us take the college campus example in detail, for a university campus or school campus, in order to maintain the information between all the departments, the whole campus is connected through the Internet,

Campus Area Network

Libraries, core departments, administration offices, and all connected to the Wi-Fi to maintain the connection amongst each other.

Now this CAN connects the library, administration office, and all other departments in the college. This campus area network is only limited to the campus, no other unauthorized user can retrieve the information out of the campus. Any confidential or student information, faculty are maintained confidentially in the campus area network.

When a computer wants to interact with the other computer, it maintains some rules between the two networks. This Network is connected through the OSI(Open system communication model).

Normally Campus are network is similar to Wi-Fi, the internet access maintained only to a limited distance. But, The Information on the campus can be accessed only by the faculty of the campus. All the Student information, faculty information and all are other confidential information are maintained only by the authorized members of the Campus area network.

Before learning the connection of campus area network, firstly we need to know the local area network.

The local area network is a network that connects all the building houses and offices within that network. Many work stations within the area are connected through the local area network. The distance for the local area network is not more than the kilometer. The data rate in the local area network can be 10 to 1000 Mbps. This Local area network works based on the IEEE 802 standard.

All the houses buildings are connected individually. This Router is present in every individual house and building. Now, All these routers are connected to a network called the local area network.

All the buildings and network are connected through a router. This LAN is then connected to the Wide area network.

Now we have known the basics of the local area network let us know how the Campus area network works. These CANs, can also a computer network that is connected with the two or more local area networks within a limited distance. Many buildings and houses are covered in the CAN. This Campus area network is widely used in hospitals, laboratories, libraries, colleges, and school campuses.

This campus area network covers two or more local area networks. We can access the internet up to 5 or 10 kilometers. in the campus area network

Now let us know the connection in the campus area network using cisco packets. To discuss in detail the campus area network, first, we have to know the cisco packets transmission. When we want to search for a piece of information on the server-side of the program, the server sends the data in the form of small packets. How the data is transferred requested to the user site? To know the solution to the above question, let study the packet tracer how the data is transmitted.

let us take an example of campus area network topology. The below diagram is the topology of the campus area network. The figure shows the physical connection in the network. The campus map contains an internet service provider. This Internet service provider (ISP) connects different LAN networks in the campuses and the hostels. In the campus area, network different network rooms are present in the LAN local area network that all finally connects to the campus area network.

The Network room consists of a Wi-Fi modem that gets connected, laptops and phones are directly connected to the sockets in the network room. The same process is maintained in all different campus area networks. Every campus has its own device that can be only accessed within the campus network, so when a user requests a piece of information in the campus area network, the request moves into the server. Now this server responds to the requested user.

The main difference between the local area network and campus area network is, we interlink the connection between the networks of multiple buildings, home networks, and offices. But we do not interlink the connection between the buildings in the LAN (Local area network).

These campus area networks are very helpful for the university’s network connections and other office buildings. The campus area network is similar to the wide-area networks when the user requests particular information it goes to the server and sends the information in the form of packets. But these are some rules and conditions in the campus area network.

The Campus area network can access only within the campus area. All these departments can communicate with each other in the Network. These are similar to the Metropolitan area network but smaller than the MAN and WAN.

There are many more types of networks like MAN, LAN, WAN, and CAN. Each network is different in functions and connections between the network. The most important categories in the network systems are the local area networks and wide-area networks. Other types of networks are also used in the different categories are the Campus area networks and the metropolitan area networks. We simply can say that CAN and MAN are the larger versions of the local area network. It combines the multiple local area networks in it to connect together for network access.

All the hospital branches, College campuses, school campuses, and more all come under the CANs.

Lets us learn the features and the functioning of the local area networks.

Campus Area Network (CAN) With Example

Let us take a hospital example for the campus area network. There are different departments like Orthopedic, Neurology, general medicine, general surgery, plastic surgery, nephrology, urology, pulmonology, pharmacy department, Operation Theatre lab, city scan, and hospital management, and all can connect through the Campus area network. All these departments are interlinked with each other. Similar to the local area network. But all the local networks are not connected in the LAN connection as the campus area network.

A Separate network room is present in the different areas in the Hospital. All the department networks are connected through a Wi-Fi Modem. In the hospital, all the patient’s information and surgery and bill payments, and room allocations, food arrangements of all the department’s connections are maintained through the Campus area network. Simply the sequence of multiple local area networks yet less than the Metropolitan and the local area networks.

It is useful to know the quick and detailed information of a patient by entering the registration number in the hospital database.

Let us take the school campus network, how the school and college networks are connected to communicate with the different departments. libraries, different departments, administration departments, Lab rooms, Electrical equipment rooms, mechanical machines, and many more different branches of the colleges are connected through the campus area networks. Now a special room is established in each department of the campuses. And all these are then connected through a Modem. If any information wants to be retrieved from the Campus area network, the user should have been an authorized person and we cannot share the information with outsiders of the campus. All the fee management, Wage managements are also maintained confidentiality to ensure the security for the students and the faculty.

Features of Campus Area Network

Let us know some of the characteristics of the Campus area networks.

Business networking Network – Nowadays, the campus area networks are mostly used in Business and different enterprises. Business networking has the highest growth in its sales and earnings growth.

Server Networks

In all the marketing sales, server marketing has the slowest growth comparing to all the other fields.

Storage Network

There is an increase in the demand for storage networking. We can store all the stuff, Over 9.6 million peoples are using storage networking.

Advantages of the Campus area networks

The Advantages of CAN are following. These are:

Cost effective

The Campus area network is very cost-effective. only a limited no of switches routers are used in the campus area which reduces the economical burden for the Campus. We can decrease the Economical cost of using simple hubs for that connection of the different local area networks.

Uses the Wireless connections

In campus area networks we use the wireless connection to connect the different local area networks, there will be no physical damage occurs in the wireless network. Due to the limited distance, the data will be transmitted and retrieved within the faster than in the metropolitan and the Wide area network.

By using the wireless connection to connect different campuses and branches, there will be no delay in the transmission and no congestion occurs due to the less traffic in the network. And we can search for any information in any type of circumstances if we are authorized to the Campus area network.

Using the Internet Service Provider

To provide internet access a unique Internet service provider is used in the Campus area network. All the local area networks are connected to the Internet Service Provider. This Internet Service provider provides (ISP) Provide services to all the departments and the branches of the campus area network. The Buildings and Homes should subscribe to the Internet Service provider to access the information in the CAN.

Easy Data Transfer

The Transfer of the data in the campus area network is easy and reliable. there will be no data congestion or collision occurs in the campus area network. Due to the less traffic and the data, we can send or receive the data fastly. The Internet service provider also assure security during the transmission of the data. The transfer of the data is easy and simple, so many people are using the campus area network for data transmission.

Disadvantages in the Campus area network


The Mainatainence of the campus area network is very expensive and many of the university and small businesses are not providing the campus area network.

Limited connections

In the Campus area network, there are limited nodes. There is a limited no of connections in the campus area network. so that the data transfer is fastest than in the metropolitan and Wide area.

The Campus area networks are only used for limited distances, we cannot use them for the large area networks.

The Automotive applications are used in the campus area networks.

All the Organizations, companies, schools, colleges, universities use the campus area networks.

Summary for the Campus Area Network

The Campus area network is called the CAN. It is mostly used for the Universities and all the educational institutions and buildings. The Network can be accessed only at a limited distance. The campus area networks are similar to the local area networks.

It interlinks the different local area networks in it. The communication is maintained in the Campus area networks. The router is maintained to connect the networks of all the departments. The Special networking service is maintained in CAN.

The Internet Service Provider (ISP) is used to supply internet access in the campus area network. This internet service provider is specially established for the campus area networks. For the Supply of the Internet service provider, the users should access the Internet service provider.

After subscription to the Internet Service provider, access is provided to the authorized user. The main advantage of the Campus area network is we can assure the security of the student information and the faculty information of the data.

It has the fastest transmission of the data in the CAN due to the less traffic flow. Only the limited members are able to access campus information. A limited no of nodes and networks are connected to the campus area networks. the Best Example for the campus area networks is the College campus networks.

It consists of the individual networks for the libraries and different departments on the campus. the network is connected through the router. a router is used to provide the internet and to send and receive the data from the other different routers or switches.

All these routers are then connected to the special modem or Sitch or hub in a Network room. A separate network room is maintained for each of the internets. This is called the Campus Area Network. The Campus Area network provides the internet to the campus for limited distances.

It can be connected through a wireless area network. The Wire Less area network reduces the congestion and no data delay occurs in the Campus environment. The Campus Area Network is absolutely greater than the local area network but smaller than the metropolitan area network and the Wide area Network.

There is a slight difference between the campus area network and the local network area network, the Local area network provide is the collection of different buildings houses offices. All this is connected through the router, switch, or hub but, it doesn’t interlink different routers to communicate with each other. But, In the Campus area network, the information can be stored only within the campus environment.

we can also communicate different individual local area networks than are present within the campus. The main use of this campus area network is to maintain the interactions and to share the information from the network within the campus. The Campus Networks share the information in the form of packets.

The data is divided into multiple packets. When the authorized user Requests a webpage or the student information, the login credentials are entered that are given by the campus staff, the server checks whether the user is authorized to access the information or not and. If it is authorized then the server provides the service to the user request. this server takes the requested data and searches for the data.

After the data is found the data is sent in the form of the Cisco packets. Each packet can store only a small amount of the data. many of the universities, Big industrial companies use the CAN due to the low cost and fastest performance is provided by the Internet service provider.

It also has limited data traffic so that there are fewer delays in the transmission of the data. It is simply like a Wi-Fi connection that connects the different networks. The features of the local area network are mainly used for the storage networks, enterprise networks, and sever networks, there is a huge growth in the enterprise and business networks compared to the server and the storage networks.

the storage network can also have a high demand in recent days, many of the universities, small business owners are using the campus area network due to the cost-effective and fastest data transmission. It has a high data rate than the local area network and wide area network. Due to the user of the internet service provider, there is no need to maintain the Internet server all the time. The Internet service provider handles all the maintenance frequently.

The benefits are more in the Campus Area Network than the Local, Metropolitan and Wide area. All the automotive applications, Educational Institutes, small business holders, enterprises, schoolings are the main applications of the Campus area network.

Second Explanation of Campus Area Network (CAN)


In this age of Information technology and with the advances happening in semiconductors, processors, and communication, Computers can communicate with each other. This happens through the arrangement of hardware and software in a planned way. Campus Area Network (CAN) is one of the ways to achieve this. Basically, CAN be defined as a connection of various (two or more) Local Area Networks (LANs) in a limited geographical area. While the LAN may be limited to a building or residence or school etc, CAN connect several buildings in a limited area.

A CAN is thus wider than LAN but smaller in geographical spread than Metropolitan Area Network (MAN). CAN be used in interconnecting networks in Military bases, dedicated laboratories, educational campuses i.e. of schools or universities or various departments in a limited geography.

This limited geography may extend from one to five Kilometres in range. Almost all the equipment and physical hardware used in CANs are owned by the campus owner. This campus owner may be a university, government department, corporate entity or an organization.

In a CAN, computers may be wirelessly or wire connected. Along with the sharing of computer resources, data, research work, information, etc, CAN make a private network within an organization. Also, since sharing of resources occurs on a CAN, there may not be a need to install software on all the computers and thus users can access and use software through the network. Such services are provided by servers placed in the network.

Now one may wonder about the workings of a CAN. Basically, CANs work on similar principles as that of a LAN, but on a larger scale and with more connections and resources required. Computers connected to the network can broadly be differentiated into two categories, i.e. Servers and Workstations.

Humans don’t generally use Servers directly, but these servers run continuously to provide lots of services such as software hosting, file storage and sharing, data storage and access, security, safety, and other such features. Humans interact with the network and utilize their services through the Workstations. Workstations may be a desktop, laptop, android devices, iPhone/iPad, etc. Servers are more powerful than Workstations and have higher speeds and very large storage than the Workstations.

Thus, a LAN in a CAN may comprise various Servers and Workstations connected through cables or through wireless mediums, but typically wired connections may be found in a LAN. CAN may be arranged by connecting different LANs through routers, switches, hubs, copper wires or optical fiber. But in most cases nowadays CANs are connected through more economical wireless mediums as compared to wires and cables.

So, multiple LANs interconnected together to form a CAN may connect to each other via wireless mediums. But this preference depends on the organization’s economy and preferences. Also, since a CAN is limited, so the data transfer rates in a CAN are faster as compared to a Wide Area Network (WAN) or MAN.

So now one may wonder about the ways in which the devices in a CAN may be connected i.e. about its topology. The topology of a CAN may be of various types depending on the requirements and economy, availability of resources.

A Campus Area Network (CAN) may be connected in mesh, star, ring or bus topology. Different LANs within the CAN may have their own topology for connection and communication amongst its nodes. So, varying LAN topologies can still be connected to each other even if they use the same or different physical means or protocols. Also, Bridges, Ethernet cards, hubs, switches, and routers play their respective roles in such connections.
