For the business that requires stability, high security, wired LAN is the top choice.
- Advantages of Wired LAN: Speed transmission, stable, less affected by noise, easy to control. This model is ideal for business with office, fixed, there is the need to transmit large data such as data center, server room.
- Actual figures: According to a report from Cisco, wired LAN minimize disruption connected to 35% compared with the wireless network in the work environment have high density, help to improve work productivity, user experience.
3.2 Model LAN wireless connection (Wireless LAN)
Wireless LAN (WLAN) brings maximum flexibility, in accordance with the open office, business wishing to connect more mobile devices.
- Advantages of Wireless LAN: No need network cable, to help business save cost, easy to change the structure of the office. With wireless networking, staff move freely but still stay connected.
- Limitations and solutions: WLAN can be subject to interference or security risks. To overcome this, businesses should implement WPA3 security settings, such as partition a network for guests and staff.
3.3 Model LAN combined (Hybrid LAN)
Model network combining wired and wireless are becoming more popular, better meet the diverse requirements of the modern enterprise.
- Benefits of Hybrid ORCHIDS: Business benefit from the stability of the wired LAN in the important departments such as IT or finance, at the same time leveraging the flexibility of the WLAN for those departments wishing to move much.
- When should select Hybrid LAN: With business medium and large scale or office divided into many regions, Hybrid is onerous to the optimal cost-effective deployment.
4. Benefits of model network for business
With respect to the corporate LAN is not just a tool to connect, but also to bring more practical benefits from optimized performance, security to cost savings. Here are the main benefits of LAN in the corporate environment.
4.1 performance optimization work
LAN environment, high-speed connection between devices in the same system, allowing employees to access and share data, documents, software, quickly. A study by Forrester shows business network deployment has the ability to reduce the time to access the resource, data processing, up to 30% compared to business there is no LAN connection, helping increase the working performance of the whole team.
