Escort vehicles need to move during missions, so wireless communication technology is a must. However, due to the random dispatching nature of these vehicles, conventional wireless communication technologies struggle to support their network connectivity. A detailed comparative analysis is as follows:
These are typical “public network technologies,” characterized by coverage from telecom operators’ networks—no additional base stations need to be built, coverage is wide, and initial investment is low. Nevertheless, they are completely unsuitable for the temporary networking needs of escort vehicles, for the following reasons:
Signal Coverage Defects: Telecom operators’ 4G/5G signals have poor coverage (or even no mobile signal at all) in suburban areas, development zones, scenic spots, or remote regions, making network connectivity impossible. Even in urban areas, the coverage quality of telecom operators has declined in recent years, as the cell radius of each generation of mobile communication technology has gradually shrunk.
Access Capacity Limitations: Even in areas with 4G/5G coverage, the limited access capacity of telecom operators’ base stations—coupled with constraints on radio frequency resources—makes it difficult to meet the network connectivity needs of high-data-volume private networks (e.g., multi-channel video surveillance streams).
Reliability Issues: Transmission stability is restricted by operator resources. Fluctuations in “number of users on the network” lead to low bandwidth stability and unreliability, while bandwidth itself is too low to support true high-definition (HD) image transmission. These factors reduce system reliability, resulting in the common problem of “working well during tests but failing when most needed”—i.e., “dropping the ball at critical moments.”
Unbearable Data Costs: The pay-as-you-go (data-based) pricing model becomes an “unbearable burden” for the system in the long run. If operators only offer data package plans (instead of time-based billing), transmitting a single 1080P HD video stream via 4G/5G for 24-hour monitoring would exhaust a 20GB monthly capped data package in less than one day, leading to extremely high long-term costs.
More importantly, 4G/5G networks connect to the Internet via wireless links, exposing them to constant hacker and virus threats. They should never be used as a solution for systems requiring independent networking (such as escort vehicles, which have high security demands). With proper cybersecurity measures in place, this technology is only suitable as a supplementary networking method.
The rapid development of WiFi technology has made it an ideal LAN (Local Area Network) extension system. However, using ordinary 2.4G or 5.8G WiFi systems (compliant with IEEE 802.11a/b/g/n/ac/ax protocols) to build a MAN (Metropolitan Area Network) has inherent shortcomings:
Coverage: Most common WiFi systems are designed for indoor wireless coverage, with a typical coverage radius of 100–150 meters. Achieving full urban coverage would require building an excessive number of base stations—making construction coordination difficult and maintenance challenging. Even if operators’ existing WiFi coverage systems were used (converting them into “public networks”), it would be hard to guarantee service quality, and security would be questionable.
Service Performance: Ordinary WiFi systems are shared-network technologies, leading to significant bandwidth fluctuations. While this is not a major issue for data services like web browsing, WiFi systems are inadequate for video services that require stable bandwidth and large data volumes (e.g., video surveillance private networks).
Frequency Interference: A more critical issue is that the 2.4G frequency band is currently overcrowded, with numerous systems and devices competing for frequency resources. Telecom operators and many enterprises/institutions are building their own WiFi coverage systems, causing severe mutual interference and greatly reducing system availability.
In summary, both technologies mentioned above have fatal flaws. The command and dispatching of escort vehicles must rely on a dedicated wireless network. If 4G/5G public networks were used to connect to the Internet, how could network security be guaranteed? After all, if the real-time trajectory and images of escort vehicles were hacked, intercepted, and livestreamed—or exploited by criminals—the consequences would be unthinkable.
Escort vehicles require dedicated wireless technology for exclusive use in a private network, with true “physical isolation” from the Internet. Guoxin Longxin’s iMAX-8000H High-Capacity Mobile Wireless MAN System or Huanyou Low-Frequency MESH Mobile Communication System are customized dedicated network solutions. With their advantages of speed, flexibility, and high bandwidth, they are highly suitable for this application scenario.
II. Design of the Escort Vehicle Internet of Vehicles Solution
The internet of vehicles for escort vehicles needs to cover the main urban roads where the vehicles operate, especially key locations such as bank outlets. The iMAX-8000H supports mobile high-capacity service access, with a maximum wireless air interface transmission rate of 600Mbps per sector. The iMAX-8000H features technical characteristics such as ultra-long outdoor distance, high speed, high bandwidth, high reliability, and high-performance image processing. Due to its ultra ultra-long communication capability, usually only a small number of iMAX-8000H metropolitan area network private network base stations are needed to achieve cross-coverage of an urban area.
The iMAX-8000H has node self-configuration, self-discovery, self-regulation, and self-healing capabilities, which are suitable for mobile temporary networking. It is highly suitable for various mobile temporary networking and roaming applications such as vehicle-mounted, airborne, and shipborne. Aiming at the needs of fast mobile communication networking for vehicles, ships, aircraft, etc., this series of products well solves common problems in outdoor mobile applications such as high-speed movement and smooth roaming between multiple base stations, and has a certain non-line-of-sight capability. It can be called an ideal choice for IP mobile private network access applications, as well as applications such as vehicle-mounted/shipborne/airborne large-capacity digital high-definition video surveillance systems and data-voice communication. For specific indicator parameters of the product, please refer to “iMAX-8000 Series Wireless Metropolitan Area Network Access Network System”.
For vehicle-mounted mobility, if the number of vehicles is small, especially in scenarios where they cooperate with UAVs, the low-frequency Huanyou MESH mobile communication system can also be considered to solve the networking problem. This system has strong non-line-of-sight capability and supports high-speed movement. Guoxin Longxin has also specially designed UAV airborne terminals to solve the networking between vehicles and UAVs, and between UAVs and the command center. Therefore, this system is very suitable for emergency temporary rapid deployment and control of a small number of nodes. For specific technologies and applications, please refer to the article “Why UAVs Cannot Do Without Huanyou Wireless Private Network?”.
If users want to use the operator’s 4G as a backup supplementary communication system, they can choose Guoxin Longxin’s iMAX-4GW300 series iMAX wireless metropolitan area network and 4G LTE dual-mode wireless network system as the vehicle-mounted terminal. It supports both iMAX-Wireless wireless metropolitan area network technology and 4G LTE (FDD-LTE & TDD-LTE) technology. In addition to supporting the wireless metropolitan area network (WMAN) mode, it can also meet the 4G network access needs of different telecom operators. It is suitable for scenarios with low bandwidth, low data volume, and low requirements for reliability and real-time performance in areas covered by 4G signals without regional restrictions, and is used to build IP public networks or VPN virtual networks. The technical features of this product are multi-mode and remote control. Please refer to the article “Communication + Control Integration, Really Good! Cost-Effective Solution for Remote Networking and Control in Different Places”.
To sum up, the wireless private network system for the command and dispatch of escort vehicles can carry various services such as high-definition video surveillance, vehicle and personnel data, and IP broadcasting. The typical application topology diagram is as follows:

Real-time positioning of escort vehicles can adopt the Beidou positioning solution. For positioning in private networks, Guoxin Longxin’s Beidou positioning terminal can be selected. Please refer to the article Why Use Guoxin Longxin’s Beidou Terminal for Positioning?.
Through the networking of escort vehicles, not only real-time high-definition video surveillance images inside and outside the vehicles, but also vehicle and personnel data (such as positioning information, vehicle status information, personnel information, etc.) can be interconnected with the backend command center in real time, providing first-hand information for resource scheduling and rational allocation. Subsystems such as the real-time presentation and storage of networked on-board high-definition video surveillance, two-way voice intercom and broadcasting, and real-time display and storage of vehicle positions and trajectories will enable the entire escort process to be presented in a three-dimensional manner to safety supervisors, improving the efficiency and scientificity of command.
III. Summary
Once the private network for the escort vehicle Internet of Vehicles is established, the management party will actually have a TCP/IP private network covering the urban area, which is reliable, secure, and stable. With network connectivity, almost all IT applications can be supported, such as vehicle digital twin systems, trunked intercom systems, and emergency command and dispatch systems.
Due to differences in the operating areas of escort vehicles, the transported items, and users’ requirements, the safety management, scheduling, and command system for escort vehicles needs to be developed in a customized manner. Guoxin Longxin has professional software partners that can tailor corresponding management platforms for users.
The number of escort vehicles exported from China is increasing. The more severe security environment abroad has created an even more urgent demand for escort vehicle networking and real-time scheduling and command. Providing the escort vehicle private network solution as a supporting system for exported escort vehicles will give vehicle manufacturers a greater advantage in exports.
Based on years of technical strength and project experience in successfully completing mobile communication projects, Guoxin Longxin can customize the most suitable system scheme design and provide the optimal solution for users.
