ToggleNetwork system construction and installation for offices is an essential solution to ensure stable connectivity, support smooth workflows, and enhance productivity. The construction process must be carried out professionally, ensuring safety, reliability, and future scalability. Let’s explore this service with Co-IDB in the article below!

What does office network construction include?
Office network construction consists of two main parts: Internet network and Internal network (LAN). The Internet ensures stable connectivity for information access, communication, and online business activities. Meanwhile, the LAN connects internal devices, allowing fast information exchange and data sharing between departments. The combination of these two systems is the foundational factor that helps an office operate flexibly, efficiently, and professionally.

What is an office LAN? How is it different from the Internet?
A LAN (Local Area Network) is an internal network system used in an office to connect devices such as computers, printers, and other smart devices within a limited range. LAN helps share resources and information quickly and effectively, contributing to improved coordination and productivity.
Devices in a LAN usually connect via Ethernet ports or network devices like switches and routers. Common network cables for LAN include CAT 5e and CAT 6 UTP cables, ensuring stable and reliable transmission speeds.

What role does LAN system installation play?
After setting up a LAN in the office, computers and devices can easily share resources such as data storage, printers, and other equipment. Users can exchange data and images, and edit or copy files on other computers conveniently, as if they were working on their own machine.
Sharing common resources—such as printers, fax machines, storage devices (HDD, FDD, and CD drives), and webcams—helps optimize performance and save costs. Additionally, users on the same network can share files and programs, enhancing collaboration and work efficiency.

Office network construction and installation process
1. Survey and Network System Design

Receive and record detailed requirements from the customer
-
Clearly define the purpose of device use according to customer needs
-
Survey the site, assess the building structure, and actual installation locations
-
Check construction conditions, material quality (cables, pipes, brackets…), and factors that could impact the system such as power sources, environment…

2. Detailed Network System Design
-
Establish detailed technical drawings of the system, including the type of devices used (pricing, technical features, warranty periods) along with logical and physical installation diagrams
-
Accurately estimate the quantity of materials and accompanying components
-
Propose optimal construction plans suited to requirements and actual conditions
-
Provide a detailed timeline for construction to ensure precise progress

3. Installation according to drawings
-
Install electrical components such as plastic pipes, gels, and wires according to technical standards
-
Execute network cabling accurately according to the approved design, similar to office electrical installation
-
Mark cables and connect them to centralized devices like Switches, Routers, Firewalls…
-
Connect computers to the network system, ensuring stability and security
-
Integrate peripheral devices into the network for synchronized operation

4. Office Network System Configuration
-
Segment users into VLAN groups to optimize the system and enhance security
-
Configure Routers, set up routing protocols, and load-balancing to ensure network performance
-
Configure firewalls and set up DMZs for servers to protect critical data
-
Install operating systems and configure network services for Servers
-
Create user groups and set permissions for each account based on job functions
5. Testing and Handover
-
Thoroughly test compatibility and stability to ensure smooth operation
-
Hand over design contracts, network diagrams, and detailed documentation directly to the customer
-
Guide the customer on detailed system use and operation

Required standards for office network construction
- Cabling structure standards: Use CAT5e, CAT6, or CAT7 cables depending on bandwidth needs. Cables must be installed according to the diagram, respecting maximum distance limits to avoid signal loss.
- Network equipment standards: Devices like switches, routers, and firewalls must support scalability, stability, and high security.
- Security standards: Protect the network with firewalls, VPNs, and data encryption.
- Cable and system management standards: Network and power cables must be neatly arranged in pipes or trays for safety and easy maintenance.
