- Example: You can opt for a 20 Mbps EPBX connection with 8 landlines, 10 IP Phones, and 20 Mbps Internet Data Connectivity. This will be suitable for up to 20 users.
Select the Network Hardware
Next, you will need to select the network hardware such as routers, switches, and access points. Depending on the size of your office, you may opt for different models with more features or higher speeds.
In addition to this, you will also need cables for wired connections and Wi-Fi routers for wireless connectivity. You can purchase these from any computer shop or online store.
- Example: You may opt for a 24-Port Gigabit Switch (Cisco Catalyst WS-C2960X-24TS-L), a Router with 4-port Gigabit (Netgear, Cisco), an Access point (TP-Link, Cisco, Google).
Select Security/CCTV Devices
You will also need to select security devices such as firewalls, antivirus software, and CCTV cameras. The type of security device you select will depend on the size of your office and your budget.
- Example: You may opt for a firewall (Sonicwall TZ400) with Antivirus Software (Avast) and 4 HDCCTV Cameras (Amcrest) for your office.
Select Network Cables
You will also need to select the appropriate cables for wired connections. Depending on the type of connection you have, you may opt for Cat5e or Cat6a Ethernet cables.
- Example: If you are using a Gigabit Switch and Router, then you should use Cat6a Ethernet cables as they provide better speeds compared to Cat5e cables.
Select the Server & Printer/Scanner
To complete the setup, you will need a server for hosting applications and services. Depending on your needs, you can opt for a physical server or a virtual one. You may also need to purchase a printer/scanner if required.
- Example: If you want to host an email server with Microsoft Exchange, then you should opt for a physical server such as Dell R620 or HP ProLiant DL380 G9.
After selecting the hardware, you will need to install and configure them.
Installation of Network Hardware
Once you have selected the hardware, you will need to install and configure them. This may involve routing cables from one device to another, setting up switches and routers, installing firewall software, and configuring access points.

What network topology is used in offices?
The most common network topology used in offices is a star topology. In this type of network, all the devices are connected to a central hub or switch which acts as the single point of communication between them. This arrangement allows for easy expansion and upgrades since new devices can easily be added to the existing setup.
Another popular topology is a mesh topology where each device is connected to multiple other devices, allowing for redundancy and increased security. This type of setup is more expensive but provides better performance and reliability.
Which type of Network is Good for Office Network?
The best type of network for an office is a Local Area Network (LAN). This type of network provides fast and reliable connections, as well as secure access to data. It also allows users to share resources such as printers, scanners, and other devices.
A LAN can also include different types of networks such as switched Ethernet or wireless networks. Switched Ethernet is the most common type of network used in offices since it offers high-speed data transfer. Wireless networks provide flexibility and convenience, allowing users to access the network from anywhere in the office.
How Does Office Network Set Up Different from Home Network Set Up?
The main difference between an office network setup and a home network setup is in the security measures taken to protect data. Office networks typically use complex passwords, encryption keys, and firewalls to keep unauthorized users from accessing corporate data.
Home networks often use basic or no security measures at all, which can leave them vulnerable to hackers and other malicious activity.
In addition, office networks typically have more complex network topologies than home networks.
Office networks often include multiple routers and switches, while home networks usually have just one or two devices connected to the internet. This allows office networks to handle more users and traffic, as well as provide increased security.
