In the application scenario of IIoT, the selection of wireless access point AP and access controller AC is crucial. Correct selection can not only improve the stability and efficiency of the network, but also facilitate subsequent maintenance and management. Here are some suggestions on how to accurately purchase wireless APs and ACs suitable for industrial IoT.

1. Key points for purchasing wireless AP Access Point

Clarify the application scenarios and requirements:

Coverage: Determine the required wireless coverage based on the size and layout of the industrial environment. Small-scale can choose low-power AP, while large-scale needs high-power AP.
Number of users: Considering the number of devices accessing the network at the same time, choose an AP that supports sufficient concurrent connections.
Transmission rate: Select an AP that supports the corresponding rate based on the type and rate requirements of the transmitted data.

Pay attention to the technical characteristics of AP:

Wireless network technology: Supporting APs that comply with standards such as 802.11a, 802.11b, 802.11g, and 802.11n to ensure compatibility with existing devices.
Power and flexibility: High-power APs can provide a wider coverage area, while flexibility is reflected in the ease of adjusting the AP configuration, such as adjusting network configuration and adding relays.
Anti-interference capability and security: Choose an AP that can effectively resist external electromagnetic interference and ensure that it has strong security protection features, such as WPA/WPA2 authentication.
Consider environmental factors:
Industrial environments may have a large amount of electromagnetic interference or complex spatial layouts, and it is crucial to choose an AP that can adapt to these environments.
Emphasize software functionality:
In addition to hardware performance, software functions are equally important, such as management convenience and stability.
Focus on compatibility and scalability:
Ensure that the AP is compatible with existing network systems and has certain scalability to meet possible future expansion needs.

2. Key points for purchasing access controller AC

Maximum number of management APs:
According to the scale of the industrial Internet of Things, choose an AC that can manage a sufficient number of APs. For example, PUSR's wireless AC products are named after the number of APs they can manage, such as the TL-AC300, which can manage 300 APs.

Functional requirements:
Authentication function: Authenticate wireless access users and push advertisements to ensure network security.

Load balancing: Balance the number of terminal loads on APs to prevent individual APs from being overloaded and improve the wireless experience of terminals.

Security management: such as DHCP protection, ARP protection, broadcast storm suppression, etc., to ensure the normal use of wireless networks.

Spectrum navigation: Enable clients supporting 5G bands to access 5G preferentially, make full use of spectrum resources, and improve the wireless Internet experience.

Compatibility and integration:
Ensure that AC can seamlessly integrate with the selected AP and provide a unified configuration and management interface.

Consider scalability and future needs:
Select an AC with scalability to meet the growth of future network size and the increase of functions.

Accurate selection of wireless APs and ACs suitable for industrial IoT requires comprehensive consideration of application scenarios, technical characteristics, environmental factors, software functions, compatibility, and scalability. Through reasonable selection and configuration, a stable, efficient, and easy-to-manage wireless network environment can be built to provide solid support for the application of industrial IoT.
