1. Trends in enterprise-level wireless coverage

With the development of the trend of enterprise office informatization and office mobility, wireless WiFi has become an indispensable part of people's lives and even work. Many companies are gradually improving and upgrading the previous wired ports due to access restrictions, cumbersome hardware maintenance, multiple lines, weak mobility and other networking problems, and starting to build more convenient, fast and mobile wireless access networks to meet the needs of the company's own development, further promoting the popularization of special tools such as remote video conferencing, network training, online enterprise office, and remote control. In order to meet the needs of high-bandwidth, multi-user, high-speed and low-latency Internet access in wireless coverage, a new generation of wireless WIFI6 came into being; before understanding our wireless coverage, the editor will talk to you about what WiFi6 (802.11ax) is and the characteristics and advantages of WiFi6.

2. What is WiFi6?

WiFi6 is the new name for the next-generation WiFi standard 802.11ax. The current mainstream 802.11ac will be renamed WiFi5, and 802.11n will be renamed WiFi4. WiFi6 has a theoretical maximum speed of 11Gbit/s, integrating 2.4GHz and 5GHz, and intelligently allocating frequency bands to bring users a high-speed Internet experience. It aims to solve the growing demand for high-bandwidth, multi-user, high-speed, and low-latency Internet access. Based on the current Wi-Fi5 (802.1lac) standard, Wi-Fi 6 integrates new-generation features such as OFDMA, UL MU-MIMO (multi-user multiple-input multiple-output), and 1024QAM to provide higher speeds, higher capacity, and more concurrent connections. It can be widely used in immersive applications such as VR/AR/MR, enterprise 4K high-definition conference offices, and indoor and outdoor high-density access scenarios for a large number of terminals. Wi-Fi 6 has greatly improved in terms of transmission rate, power consumption, space, and performance.

3. What are the advantages of enterprise-level wireless coverage?

The advantages of enterprise-class wireless coverage can be divided into four parts:

• High bandwidth: Makes WiFi nearly three times faster
• High capacity: Network capacity increased by 4 times
• Wide coverage: WIFI6 has a larger coverage radius
• Less interference: less interference, smoother network

4. Enterprise-level wireless coverage composition according to the topology diagram

After a brief description, I believe everyone has understood the benefits of WiFi6. Next, I will tell you about the composition of enterprise-level wireless coverage according to the topology diagram: gateway---core switch---aggregation switch---POE switch---terminal.

(1) Full Gigabit Enterprise Gateway (Intelligent Gateway): can uniformly configure and manage all APs in the same network

(2) POE powered switch: uses network cables to provide power and data transmission for APs;

(3) Wireless AP: It is equivalent to a bridge connecting the wired network and the wireless network. Its main function is to connect various wireless network clients together, and then connect the wireless coverage network to the Ethernet, so as to achieve the purpose of wireless network coverage;

5. Networking methods for enterprise-level wireless coverage

According to the networking mode, it can be divided into:

• Bypass Mode
• Main road mode

(1) AC bypass mode: This mode is generally used when a wired network has been built in the early stage and a wireless LAN needs to be built in the later stage. This mode is relatively simple. The POE switch is connected to the AP and the aggregation switch is connected to the POE switch. The AC controller is connected to the aggregation switch to control and configure the AP. The IP address is controlled by the upper-level core gateway, and the AC controller is only responsible for configuring and managing the AP.

(2) Main line mode: The main line mode architecture is generally built without wired or wireless connections. At this time, a complete set of line configurations including wired, wireless, traffic diversion, and user isolation needs to be built. Compared with the bypass mode, it is more comprehensive, and the IP address is issued by the gateway.

6. AP placement for enterprise-level wireless coverage

The AP deployment location is determined by the following factors:

• Consider the size of your wireless coverage area
• Distribution of obstacles in the coverage area
• The number of users who need access and the bandwidth requirements
• Where the device can be installed
• The current network configuration and export bandwidth, etc.

7. Application scenarios of enterprise-level wireless coverage

According to different application scenarios, different indoor and outdoor APs can be selected to achieve the best user needs;

8. Summary

Through the brief introduction of the editor, I believe that everyone has a better understanding of enterprise-level wireless coverage. However, when selecting wireless coverage products, you must also consider the device transmission bandwidth, switch POE power supply distance, and AP deployment location. Everyone must verify it clearly before designing and selecting to avoid subsequent failure to meet the design and use requirements!
