In-depth Analysis of Application Cases of PUSR Cellular Router in the Transportation Sector: Solving Industry Pain Points and Empowering Smart Transportation
In the transportation sector, the stability, real-time performance, and security of network communication directly determine system operational efficiency and public safety. From real-time scheduling of urban buses to signal control in rail transit, and from intelligent perception in vehicle-road collaboration to data backhaul in traffic monitoring, any network interruption or delay can trigger a chain reaction, leading to operational stagnation or even accident risks. With its military-grade reliability, multi-link redundancy design, and intelligent operation and maintenance capabilities, the PUSR cellular router has achieved a qualitative leap in network performance across multiple transportation scenarios. This article will analyze its technical value through real-world cases and explore how it can resolve core pain points for customers.
Case Background: Network Upgrade Project of a Bus Group in a Second-tier City
A bus group in a certain city, with over 500 buses, relied on a single operator's 4G cards for its original network solution. Frequent network disconnections occurred when vehicles traveled to suburban areas or tunnels, resulting in stuttering in-vehicle surveillance footage, delayed bus stop announcement systems, and a passenger WiFi complaint rate as high as 30%. More seriously, the dispatch center was unable to obtain real-time vehicle locations and statuses, leading to inefficient emergency responses.
Solution: USR-G806w Dual-link Redundancy Design
The USR-G806w cellular router launched by PUSR became the key to breaking the impasse:
Dual SIM Cards + Wired Backup: The primary network is 5G, with a 4G backup network, and it supports wired Ethernet access. When vehicles enter signal blind spots, the router automatically switches to the backup link, with a switching time of only 2 seconds, ensuring surveillance footage delay is <1 second.
On-board Environment Adaptation: To address harsh conditions such as high temperatures, vibrations, and electromagnetic interference on bus roofs, the USR-G806w features a metal casing and an IP30 protection rating, with an operating temperature range of -40°C to +70°C. It resolves high-temperature and voltage fluctuation issues through heat dissipation brackets and dual power supply designs.
Intelligent QoS Management: Bandwidth for bus stop announcement systems and surveillance data is prioritized, while passenger WiFi traffic is dynamically limited to prevent interruptions in critical services due to concentrated user internet access.
Implementation Effects:
Network Uptime: Increased from 85% to 99.9%, with annual network disconnections dropping from 127 to 1 (due to a city-wide base station failure caused by extreme weather).
Operation and Maintenance Costs: Remote management capabilities reduced the need for on-site troubleshooting by maintenance personnel, lowering labor costs by 80%.
Passenger Satisfaction: WiFi complaints decreased by 90%, bus stop announcement accuracy increased to 99.5%, and the project was awarded the "Smart Bus Demonstration Project."
Case Background: Signal System Transformation of a Subway Line
Subway signal control places extremely high demands on network real-time performance and reliability. Traditional solutions rely on wired private networks, which are costly to build and have poor scalability. A certain subway line attempted to introduce wireless communication, but ordinary routers frequently failed in environments with electromagnetic interference and vibrations, resulting in signal delays exceeding standards and affecting train operation intervals.
Solution: USR-G806w Industrial-grade Protection and Low-latency Design
Anti-interference Capability: The USR-G806w adopts a Qualcomm chipset solution, improving WiFi signal penetration by 50% and maintaining stable connections even in subway tunnels.
Redundant Communication Mechanism: It supports VPN encrypted tunnels and dual-link backups, ensuring zero loss of signal control instructions even if a single link fails, as data can still be transmitted through backup channels.
Edge Computing Preprocessing: The router incorporates an edge computing module that can locally filter and compress sensor data, reducing cloud transmission pressure and shortening the response time for critical instructions to within 10ms.
Implementation Effects:
System Availability: Increased from 99.2% to 99.99%, meeting the subway industry's reliability requirement of "six nines" for signal systems.
Construction Costs: The wireless solution saved 30% in deployment costs compared to wired private networks and eliminated the need for rewiring when expanding to new stations.
Security Compliance: It meets the requirements of Cybersecurity Classification Protection 2.0 Level 3 through IPSec VPN encryption and firewall functions, preventing data leakage risks.
Case Background: Autonomous Driving Testing in a Smart Logistics Park
In autonomous driving scenarios within logistics parks, vehicle-road collaboration (V2X) communication requires millisecond-level data interaction between vehicles and roadside units (RSUs). Traditional routers are prone to packet loss during concurrent communication from multiple vehicles, leading to decision-making delays in autonomous driving systems and even triggering emergency braking.
Solution: USR-G806w Multi-network Ports and VLAN Isolation
High Concurrent Processing Capability: The USR-G806w provides 2 LAN ports and 1 WAN/LAN switchable port, supporting simultaneous connections to on-board OBUs, cameras, radars, and other devices. It isolates different service traffic through VLAN segmentation to avoid broadcast storms.
5G + WiFi Dual-mode Communication: The primary network is 5G for transmitting high-definition maps and remote control instructions, with WiFi 6 serving as a local communication backup to ensure low-latency communication even during 5G signal fluctuations.
Real-time Monitoring and Early Warning: Through the UCloud platform, maintenance personnel can remotely monitor the router's CPU load and traffic usage and set threshold alerts to proactively identify potential risks.
Implementation Effects:
Communication Latency: Reduced from 200ms to within 50ms, meeting the network latency requirements for L4 autonomous driving.
Testing Efficiency: The daily testing mileage of autonomous vehicles increased from 50 kilometers to 200 kilometers, with a 100% data backhaul integrity rate.
Cost Optimization: A single router replaced the original combination of "5G CPE + switch," reducing equipment costs by 40%.
Transportation scenarios face challenges such as high temperatures, humidity, vibrations, and electromagnetic interference. The USR-G806w achieves "zero-fault" operation through the following designs:
Protection Rating: IP30 dust resistance certification and a metal casing resistant to impacts.
Wide Temperature Operation: A temperature range of -40°C to +70°C, adapting to severe cold in the north and intense heat in the south.
Electromagnetic Compatibility: It withstands level 3 electrostatic protection and surge pulse protection, resisting lightning strikes and power fluctuations.
The dual SIM card + wired backup mechanism, combined with intelligent switching algorithms, ensures uninterrupted service during single-link failures:
Switching Time: <2 seconds, with no business interruptions.
Operator Flexibility: It supports hot-swapping SIM cards from the three major operators, avoiding network disconnections due to insufficient coverage from a single operator.
Through the UCloud platform, customers can achieve:
Remote Configuration: No need for on-site debugging; router parameters can be modified with a single click.
Fault Early Warning: Real-time monitoring of device status to proactively identify potential issues.
Batch Management: Unified control of routers nationwide, reducing operational complexity.
Stable networks ensure real-time operation of dispatch systems, monitoring systems, and ticketing systems, reducing operational losses caused by network failures. For example, a certain bus group reduced annual operational losses by over RMB 2 million.
The USR-G806w has an average mean time between failures (MTBF) of 100,000 hours. Combined with remote operation and maintenance capabilities, maintenance costs over the equipment's lifecycle can be reduced by 60%.
