PublishTime： 2023-11-02 Article Source：usr News

The AP (Access Point) function of LTE 4G router means that it can act as a wireless access point to provide network connection services for wireless devices. Specifically, the AP functions of the Lte 4G router include the following:

1. Wireless network signal transmission function: Lte 4G router can transmit wireless signals as an AP and create a wireless local area network (WLAN). It provides network connectivity to nearby wireless devices based on configured wireless parameters such as band, channel, SSID, and so on.

2. Wireless device access management: The AP function of the Lte 4G router can manage and control the wireless devices accessed. It can limit the number of access devices, manage the connection authority of devices, authenticate and authorize devices, and maintain the security and stability of the network.

3. Network distribution and forwarding function: The AP function of the Lte 4G router can connect the wireless device to the wired network and distribute and forward the network data. It can forward the data of wireless devices to the Internet or other networks through the wired interface, and realize the communication between wireless devices and external networks.

4. Network security protection: The AP function of Lte 4G router can provide network security protection measures. It can support encryption algorithms such as WPA2, WPA3, etc. To encrypt wireless communications and prevent unauthorized devices from accessing the network. In addition, it can also support access control list (ACL) and firewall functions to restrict the access rights of specific devices and ensure network security.

In a word, the AP functions of Lte 4G router mainly include wireless signal transmission, wireless device access management, network distribution and forwarding, and network security protection. It can provide reliable network connection for wireless devices in industrial environment, and guarantee the security and stability of the network.

Industrial AP and ordinary AP are different in the following aspects:

1. Physical characteristics: Industrial-grade AP usually uses durable metal shells and industrial-grade components, which are dustproof, waterproof, and anti-interference, and can adapt to harsh industrial environments. Ordinary AP generally uses plastic shell, which is suitable for general office or home environment.

2. Operating Temperature Range: Industrial grade APs have a wide operating temperature range and can typically operate in extreme temperature conditions from -40 ° C to 70 ° C. Normal APs typically operate between 0℃ and 40℃.

3. Anti-interference capability: Industrial AP can resist interference factors such as electromagnetic interference, vibration, and dust in an industrial environment through special design and anti-interference technology. However, the anti-interference ability of ordinary AP is poor, and it is suitable for a relatively clean and non-interference environment.

4. Network stability and reliability: Industrial AP usually has a more stable and reliable network connection, which can ensure the stability of data transmission. It is suitable for industrial automation, the Internet of Things, and other scenarios with high requirements for network connection. The ordinary AP is mainly used in the general office and home network environment.

5. Scalability: Industrial AP usually supports more expansion interfaces and functions, such as external antenna, serial port, alarm input and output, etc. This can meet the interface needs and extended functionality requirements of different devices in an industrial environment. The scalability of ordinary AP is usually limited.

There are obvious differences between industrial AP and ordinary AP in physical characteristics, working temperature range, anti-interference ability, network stability and reliability, and scalability. Industrial AP is more suitable for industrial scenarios with harsh environmental requirements, while ordinary AP is mainly suitable for general office and home network environments.
