Outdoor networking refers to a network solution that uses wireless communication technology, such as 4G or 5G networks, to connect devices distributed in different locations to achieve data transmission and remote monitoring in the absence of optical fiber broadband or network cables. Outdoor networking is suitable for various complex and harsh outdoor environments, such as farmland, construction sites, highways, water conservancy, etc., and can meet the needs of the industrial Internet of Things, smart cities, smart agriculture, and other fields.

The core equipment of outdoor networking is the industrial 4G/5G router, which is a high-end communication equipment specially designed for unattended outdoor scenarios. Industrial 4G/5G routers have the following features:

- High speed and stability: Industrial 4G/5G routers support 4G/5G networks and can provide high-speed data transmission and low-latency response. They also have strong signal coverage capabilities and automatic switching functions and can adapt to various network environments and signal strengths.

- Safe and reliable: Industrial 4G/5G routers support a variety of security encryption technologies, such as VPN, firewall, DMZ, etc., which can ensure the confidentiality and integrity of data during transmission and prevent it from being stolen or tampered with. At the same time, industrial 4G/5G routers have functions such as power outage protection, disconnection reconnection, and remote maintenance, which can ensure the normal operation and fault recovery of the equipment.

- Industrial-grade protection: Industrial 4G/5G routers adopt industrial-grade designs and materials, and are dustproof, waterproof, shockproof, and resistant to high and low temperatures. They can resist the effects of severe weather, temperature changes, or other adverse factors, and are suitable for various harsh environments. outdoor scene.

- WiFi wireless technology: Industrial 4G/5G routers can provide WiFi networks to facilitate users to wirelessly access the Internet within range. This is particularly useful for industrial applications that require real-time remote monitoring or control of mobile equipment.
