What is Campus Area Network (CAN)?

Campus Area Network (CAN) is also called a corporate area network and it helps to like LAN with small geographical space. The main objective is offering the best accessibility of campus residential regions like schools, colleges, university, small institutes (Campus), and corporate area (building). It is larger than LAN but small than WAN and MAN networks

It can cover many buildings in an area. Here all computers are connected together and have some relationship to each other.

For example − Different buildings in a campus are connected using Campus Area Network (CAN) they help to interconnect departments, library and computer laboratories.

Given below is the diagram representing how CAN connects different buildings in Campus −


The advantages of CAN are as follows −

  • Affordability − To construct CAN networks we use hardware devices like hub, routers, switches, cables which are affordable.

  • Easy accessibility of data − We can easily access the data that are present in different departments with the help of CAN.

  • Wireless medium − With the help of wireless connection we are able to link offices which are present in different buildings.

  • Higher speed − CAN is supported to transfer large files or data with high speed over a network with the help of the internet.

  • Protection − CAN networks have firewalls and proxy servers which are used for security purposes.

  • Share internet connection − CAN network will share internet connection.


The disadvantages of CAN are as follows −

  • It does not support a maximum number of nodes.

  • It can connect only up to 64 nodes because of electrical loading.

  • CAN maintenance is costly when compared to other networks like LAN, SAN, WAN etc.

  • It can support up to 40 meter length.

  • There are undesirable interactions in between all nodes.


The places where the CAN is used are given below −

  • School campus
  • University campus
  • It is used in large organization and industrial sites.
  • It is also used in automotive applications.
