🧱 1. Main components of building network system design

Subsystem	Functional Description
Backbone Network	Responsible for connecting network traffic between floors or computer rooms, usually using optical fiber or Cat.6A/7 cable.
Horizontal Cabling	Extend network signals from the floor wiring room to each terminal point (for example: conference room, office desk, etc.).
Equipment room (IDF/MDF)	Placing core network equipment such as switches, firewalls, and servers requires cabinet design and heat dissipation and ventilation planning.
Wireless network (Wi-Fi AP)	To provide wireless Internet access, the number and location of hotspots must be accurately planned to avoid blind spots.
Network security design	Includes VLAN division, access control, firewall, anti-virus, intrusion detection and other measures.
Computer room power and backup system	Including UPS, generator, dual power supply and other designs to ensure the continuous operation of the equipment.

Before Design

Basic information you need to provide:

1. Building Type and Floor Information

• Building use (such as office buildings, residential buildings, medical treatment, campuses, factories, etc.)

• Total number of floors and area (for example: 6 floors above ground, 1 floor underground, 300 pings per floor)

2. Network requirement type

• Estimated number of users (including office staff, residents, guests, etc.)

• Which systems need to be connected to the network (for example: monitors, access control, IP phones, IoT devices, etc.)

3. Equipment requirements

Some key points in building network system design

When we talk aboutKey points of building information network system designWhen designing a building, the main thing is to plan a "secure, stable, scalable and easy-to-maintain" network architecture to support all information and communication needs in the entire building. The following are some of the things you should pay special attention to when designing.Key Points:

---

✅ Key points of building information network system design

1️⃣ Structured Cabling System

• Comply with international standards such as TIA-568 / ISO/IEC 11801.

• It adopts the **Backbone (Backbone) + horizontal wiring (Horizontal)** architecture.

• Use Cat.6A or higher network cables, and optical fiber is recommended for important sections.

• designWire duct paths, bridges, wiring boxes, considering later maintenance and expansion.

2️⃣ Planning of computer room and wiring room

• set upMDF (main distribution room) and IDF (floor distribution room).

• Pay attention to the air conditioning, UPS power supply, floor load-bearing, dust-proof and anti-static design.

• The location of the equipment room should be central and convenient for pipeline layout to avoid being too far away and causing signal attenuation.

3️⃣ Network equipment selection and architecture

• Select switches, firewalls, routers and other devices according to usage requirements.

• useCore switch + edge switchArchitecture.

• designNetwork traffic distribution (VLAN), such as separate management of employees, guests, IoT, and monitoring.

• Need to considerPoE Requirements, supply power to IP phones, monitors, wireless APs, etc.

4️⃣ Wireless network (Wi-Fi) design

• Plan the number and location of Access Points (APs) based on the site area and shielding conditions.

• Use hotspot simulation tools such as Ekahau to estimate signal coverage.

• designMultiple SSID and VLAN binding, such as employee network, guest network, and IoT device network.

• supportRoaming and centralized management functions (such as Controller).

5️⃣ Security design

• Firewall, intrusion detection/prevention system (IDS/IPS), MAC binding.

• VLAN isolation, ACL access control.

• For important equipmentDual power supply/dual network path redundancy design.

6️⃣ Scalability and maintenance management

• At least 30% of space should be reserved for cabinets and wiring to facilitate future expansion.

• useSNMP MonitoringWith the centralized management platform, network management operations are simplified.

• Clearly mark the pipeline directions and joints (Labeling) and formulate a wiring SOP.

Construction piping and wiring design and equipment installation design

Things to note during construction

During the construction phase of network cabling, attention to detail is essential to ensure the final effect. First, construction personnel should ensure that the placement and fixing of the network meet the design specifications to avoid damaging the network cabling and thus affecting the quality of signal transmission. In addition, environmental factors such as temperature and humidity should also be considered to avoid construction under extreme conditions to prevent physical damage to network materials. During the construction process, appropriate tools and equipment should be used to ensure that the network is terminated and connected correctly, and necessary tests should be performed to confirm the validity of each connection. Finally, complete documentation and quality inspection steps can ensure that every link of the construction complies with regulations and industry standards, thereby providing an efficient and stable network system.

Relevant regulations and standards:

• • Building Regulations:
    The design of a building's telephone system needs to comply with local building regulations and fire safety regulations.
  • Telecommunications Regulations:
    The design of building telephone systems needs to comply with telecommunications regulations and related standards to ensure system compliance.
  • Pro Tips:
    It is recommended to seek assistance from a professional FGT engineering company or ECC consulting company to plan, design and construct the telephone system to ensure the quality and reliability of the system.
    During the design and construction process, the particularities of the building should be fully considered, such as sound insulation, anti-interference and other factors.
    Choose a supplier with good after-sales service so that you can get timely support and maintenance when problems occur in the system.
    In short, the design of a building telephone system is a complex process involving many factors and requires professional knowledge and experience. Through reasonable planning, design and construction, it can be ensured that the telephone communication system in the building can meet the needs of users and provide reliable and stable services.

Therefore, a good telecommunications system design can not only improve user satisfaction, but also effectively improve the overall building operation efficiency.
