III. Wireless Networking Solution for Geohazard Early Warning System
The adoption of wireless networking technology (especially wireless private network) for the geohazard early warning system brings significant advantages in application scenarios. It can be said that wireless networking is the most suitable networking technology for early warning systems in areas prone to geohazards such as mountain landslides and debris flows. The selection of wireless technology varies according to scenarios, the quantity and dispersion of nodes, service types and bandwidth requirements. There are two typical wireless networking methods.
3.1 iMAX Wireless Metropolitan Area Network (WMAN) Private Network Technology
The iMAX wireless communication system is designed to build wireless cities or solve ultra-long-distance network interconnection in outdoor environments, and all series of equipment support ultra-long communication distances. Among them, the iMAX-6000 series serves as the backbone network for geohazard early warning networking, and the iMAX-8000S, iMAX-8000H series and others act as the edge access network.
✅ Communication Distance: Under line-of-sight conditions, even the compact integrated-antenna iMAX 5G client system, the iMAX-8000 in point-to-multipoint mode can easily achieve 10 km radius coverage; the iMAX-6000 in point-to-point mode supports a maximum distance of 100 km, making it ideal for ultra-long-distance communication and networking in remote outdoor areas.
✅ Transmission Bandwidth: The iMAX-8000H is a 600Mbps point-to-multipoint communication system, the iMAX-8000S is a 100Mbps point-to-multipoint communication system, the iMAX-6000 is a point-to-point communication system with 150/300/600Mbps bandwidth, and the FibeAIR high-frequency IP microwave is a point-to-point communication system with ultra-high bandwidth of 1Gbps-20Gbps.
✅ Reliability & Security: The iMAX wireless private network system is an industrial and telecom-grade system, and its product quality, reliability and solution reliability are the biggest advantages distinguishing it from competitors.

3.2 iMWB 4G/5G Virtual Private Network (VPN) Technology – Wireless Wide Area Network (WWAN)
Using 4G/5G public networks as the underlying networking platform essentially deploys services directly on the public Internet. Without network encryption and reliability technologies in place, the system is vulnerable to cyber attacks that disrupt normal operations, and may even lead to network security incidents such as system crashes and data leaks. Therefore, a “SD-CX Cloud Switch + VPN Virtual Private Network solution” must be adopted to enhance system security and reliability.
For users of geohazard early warning systems, wireless private network technology only addresses on-site private network construction for individual locations. However, early warning sites are often scattered across a city, a province, or even the entire country, making wireless wide area network (WWAN) technology more suitable for centralized management networking of these distributed sites. Leveraging years of valuable experience in the IoT industry, Guoxin Longxin proposes a solution integrating SD-CX Cloud Switch and multi-mode gateways.
A cloud computing platform (or cloud platform) refers to a service built on hardware and software resources, providing computing, networking and storage capabilities. Cloud computing platforms fall into three categories: storage-centric cloud platforms for data storage, computing-centric cloud platforms for data processing, and integrated cloud computing platforms that support both computing and data storage/processing. With the development of cloud computing, nearly every enterprise is adopting or planning to adopt cloud computing, which offers three deployment models: public cloud, private cloud and hybrid cloud.
The cloud exists “on the cloud” – how to connect on-site services to the cloud? Public cloud typically uses the Internet, commonly via carrier broadband access; private cloud usually adopts VPN or dedicated line access, such as telecom carrier dedicated lines, self-built optical fiber or wireless private networks by users. As private networks are dedicated and isolated from the public Internet, their connection bandwidth, reliability and security are far superior to regular broadband. Both public and private clouds face the challenge of connecting edge nodes to the cloud.
Guoxin Longxin’s iMAX-4GW300 series 4G metropolitan area dual-mode wireless gateway system is a powerful tool for connecting cloud computing edge nodes to the cloud. The iMAX-4GW300 supports both iMAX wireless metropolitan area network (WMAN) technology and 4G LTE technology, and is equipped with multiple Ethernet interfaces, serving as a multi-network convergence gateway. In terms of wireless communication, it not only achieves high bandwidth, high reliability and high capacity via wireless private network technology, but also supports 4G LTE public network access from telecom carriers, flexibly delivering optimal wireless networking solutions for users.
The iMAX-4GW300 is an innovative product that uniquely integrates iMAX WMAN and 4G LTE wireless technologies. It can function as an integrated switching gateway platform supporting multiple access methods, including optical fiber access (with Guoxin Longxin FiberDC-IDU), LAN interconnection, MPLS dedicated line access, residential Internet broadband access, iMAX wireless private network, and 4G Internet access. Given the wide geographical distribution of early warning sites and diverse public network connection methods, support for multi-network convergence and interconnection is the core advantage of the iMAX-4GW300.
Security and stability are primarily guaranteed by Virtual Private Network (VPN) technology. VPN technology establishes a “private network” over a public network (or an encrypted tunnel over a private network to enhance security) for encrypted communication. It mainly relies on tunnel encryption protocols, with typical ones including PPTP, L2TP and IPSec. Guoxin Longxin’s solution is built on an embedded hardware VPN-based architecture (“VPN Server + VPN Gateway”), which undoubtedly maximizes the reliability and security of remote management networking.
For centralized remote management and networking of multiple off-site early warning sites, the cloud platform-based Internet solution offers the highest cost-effectiveness and adaptability. Users can choose private cloud, public cloud or hybrid cloud, and form a virtual private network across the wide area network for dispersed early warning sites via VPN tunnel encryption technology.

Guoxin Longxin SD-CX Cloud Interconnection Solution enables centralized management of early warning sites. Supported networked devices include but are not limited to servers, switches, IP cameras, PLCs, sensors, IP broadcasting systems, advertising screens, wireless communication devices and optical communication devices. To a certain extent, any device managed based on TCP/IP networks can be interconnected for remote centralized networking via this solution. In other words, various intelligent systems commonly used at early warning sites can all be carried on this system, which undoubtedly builds a highly scalable platform for users’ further intelligent construction.
It should be emphasized that the iMAX-4GW300 also supports routing, firewall and VPN technologies, providing users with a variety of secure technical means to meet the security requirements of business networking, especially when connecting to the public network. Networking through this device can effectively prevent cyber security issues such as hacker intrusion caused by exposing services directly to the public Internet (unencrypted open access).
The two solutions mentioned above are complementary and can be designed in combination: the wireless metropolitan area network (WMAN) private network is suitable for on-site internal networking or large-scale urban networking at early warning sites, while the wireless wide area network (WWAN) is ideal for centralized networking of multiple distributed early warning sites.
Certainly, designing an optimal solution for the specific networking and management needs of early warning sites often requires repeated communication and on-site research with users. Leveraging its rich experience and solid technical capabilities, Guoxin Longxin will customize the most reasonable wireless networking solution for geohazard early warning systems for users (including regulatory authorities such as land and resources bureaus, work safety supervision bureaus and housing and urban-rural development bureaus).
