- Troubleshooting takes time and technical skills.
- A single problem can affect many users.
10. Limited Remote Access Options
A CAN mainly supports users within the campus area.
- Working remotely becomes difficult without extra setup.
- You need VPNs or special tools for outside access.
- Not ideal for hybrid or remote working environments.
Alright champs, those were the key limitations of a Campus Area Network. We hope you’ve clearly understood the pros and cons of campus area network shared above. Now, it’s time to move on to the next section i.e. campus area network’s feature.”
Features of Campus Area Network (CAN)
A Campus Area Network (CAN) comes with some special features that make it useful for schools, colleges, offices, and hospitals. Let’s look at what makes a CAN different and helpful in daily use.
Covers a Fixed Area like a Campus or Office Block
A CAN is designed to work in a limited area, not across cities.
- It connects computers and devices in nearby buildings.
- Usually used in a school campus, university campus, office block, or hospital campus.
- All systems stay linked within that specific space.
Example: A college campus with separate buildings for labs, classrooms, and admin—all connected through one network.
High-Speed Connection Between Systems
Data moves quickly from one system to another.
- Uses fast cables like fiber optics or high-speed switches.
- Reduces waiting time for sending files or messages.
- Helps teams work faster and smoother.
Centralized Management and Control
Everything in the network is managed from one place.
- One IT team can control the full system from a central room.
- Easy to apply updates, monitor devices, or fix issues.
- Saves time and keeps the network organized.
Secure Data Sharing Within the Network
Data shared within the campus stays protected.
- Only authorized users can access files and systems.
- Helps prevent outsiders from stealing information.
- Security tools like firewalls and permissions can be added.
Support for Multiple Users and Departments
A CAN can handle many connected users working at the same time.
- Departments like admin, HR, library, or labs can all use it.
- Each department can have access to shared tools, files, and other network resources.
- Helps in smooth collaboration across the organization.
Supports Wired and Wireless Connections
A Campus Area Network (CAN) supports both wired and wireless technologies for better flexibility and coverage.
