Choose Industrial Wireless Routers Smartly

In the industrial field, efficient and stable industrial wireless transmission is crucial for production and operation, and as a core device, the selection of industrial wireless transmission routers is of vital importance. Here are some key points to consider when choosing an industrial wireless transmission router.

Performance parameters are fundamental

Processor performance: The processor is the “brain” of a router and is particularly important for industrial wireless transmission routers. High-performance processors like industrial-grade ARM9 communication processors can ensure that routers process large amounts of data efficiently, guaranteeing the real-time and stability of industrial data transmission.
Memory and storage: Sufficient memory and storage can ensure that the router handles multitasking and stores configuration data with ease. Routers with 64MB or more expandable SDRAM and 8MB or more expandable FLASH can meet the caching and storage requirements of large amounts of data in industrial scenarios.
Wireless frequency bands and rates: In industrial environments, there is a lot of interference. Industrial wireless transmission routers that support dual frequencies have more advantages. The 2.4GHz frequency band has strong penetration and a wide coverage area. The 5GHz frequency band has a high transmission rate and less interference. The wireless transmission rate of a router is also crucial. For instance, a router that supports the 802.11ac protocol can achieve a wireless rate of over a gigabit, which can meet the demands of high-speed industrial data transmission.

Interfaces and connectivity are key

Ethernet interface: In industrial sites, there are usually various devices that need to be connected to the network. The number and types of Ethernet interfaces of routers should be able to meet the requirements. Generally, it should have at least one 10/100 BASE-T Ethernet port, supporting the Shielded RJ-45 interface to provide a stable wired network connection.
Serial port: For some scenarios that need to be connected to traditional industrial equipment, routers that support serial ports such as RS232, RS422, and RS485 are more practical, facilitating serial data transmission with devices like PLCS and Rtus.
SIM card interface: If wireless data transmission through the operator’s network is required, a standard drawer-type SIM/UIM card interface is essential and should support 3V/5V SIM cards.

Software functionality is the guarantee

VPN function: To ensure the security of industrial data during transmission, routers that support the VPN secure tunnel function are preferred, such as those that support protocols like PPTP+MPPE+MPPC and IPSEC+L2TP, which can effectively prevent data from being stolen and tampered with.
Firewall and Security Protection: It is equipped with powerful firewall functions, such as IPTABLES firewall support and packet filtering functions, which can prevent illegal access and malicious attacks, and protect the security of industrial networks.
Remote management and maintenance: Routers that support remote WEB management and telnet management facilitate engineers to configure, monitor and maintain the routers remotely, improving operation and maintenance efficiency and reducing operation and maintenance costs.

Reliability and stability are the core

Industrial-grade design: The industrial environment is complex and harsh. Routers must have an industrial-grade design, such as being able to adapt to an operating temperature range of -25 ℃ to +65℃ and operate stably in an environment with a relative humidity of 95% (without condensation).
Anti-interference capability: There is a large amount of electromagnetic interference in industrial sites. Routers must have good anti-interference capability and pass relevant EMC tests, such as 3000V electric shock tests, to ensure normal operation in strong interference environments.
Redundancy and backup: To avoid single point of failure, some high-end industrial wireless transmission routers support functions such as redundant power supply and link backup. When the main power supply or main link fails, they can automatically switch to the backup power supply or backup link to ensure the uninterrupted operation of the network.
