PRODUCT CAPABILITIE
The Rigolink R9965 is a 4G/5G industrial VPN router engineered for mobile and temporary deployment scenarios where fixed network infrastructure simply does not exist. It provides five Gigabit Ethernet ports for connecting on-vehicle equipment, one RS232/RS485 serial interface supporting the Modbus protocol for legacy and serial-based field devices, dual-band Wi-Fi operating on both 2.4 GHz and 5.8 GHz for local wireless access, and 4G/5G cellular connectivity for backhaul to a central management platform. Designed for continuous operation in vehicle-mounted environments, the R9965 tolerates the vibration, temperature swings, and unstable power conditions typical of road and construction machinery. Its support for external vehicular antennas allows it to maintain a stable cellular link even in open highway environments where signal coverage can be inconsistent. Compact enough to be mounted inside vehicle enclosures or equipment cabinets, the R9965 serves as a dependable networking core for connected road safety systems and mobile field equipment.
TYPICAL PAIN POINTS
Road maintenance and construction crews work in close proximity to live traffic, where the primary safety objective is maximizing the distance between workers and approaching vehicles. Advance warning signage is the main tool for diverting traffic before it reaches a work zone, but traditionally these signs require manual placement and on-site adjustment. Any operation that involves a worker stepping toward the carriageway introduces serious risk from speeding traffic. The practical difficulty is that remote control demands connectivity, and wireless signal strength degrades as the distance between the operator and the device increases — so the further a worker stands from the sign, the safer they are, yet the harder reliable control becomes. Compounding the problem, road works are inherently temporary and mobile: crews relocate to new sites daily, and there is no time or budget to install wired network infrastructure at each location. Equipment must be self-contained, rapidly deployable, and capable of establishing its own connectivity wherever the work moves.
Protocol Adaptation
The R9965 acts as the networking bridge between on-vehicle equipment and the wider management system. Its five Gigabit Ethernet ports connect the full-color display controller, vehicle management unit, and any additional onboard systems to a local IP network, with spare ports left available for future equipment expansion. Its RS232/RS485 serial interface supports the Modbus protocol, allowing the router to read data directly from serial-based field devices such as environmental sensors, status indicators, and legacy controllers — converting their output into IP traffic that the rest of the system can consume. This makes it possible to integrate older equipment already installed on the vehicle without replacing it, and to unify both serial and Ethernet devices under one network. Its dual-band Wi-Fi (2.4 GHz and 5.8 GHz) provides a wireless access point that crew members can join from a mobile device carried on their person — the 2.4 GHz band offers longer range and better obstacle penetration on the open road, while 5.8 GHz delivers higher throughput for video or large-file transfers close to the vehicle. This creates a two-tier architecture: Wi-Fi handles the short-range link between the worker and the vehicle, while 4G/5G cellular carries data between the vehicle and the central platform. Because every interface runs over standard IP networking, no proprietary middleware or dedicated radio links are required. The display system, management unit, serial field devices, and operator device communicate through a single converged network established by the R9965, regardless of where the vehicle is stationed.
Remote Management
With the Rigolink Remote Management System (RMS), fleet operators can monitor and maintain every deployed R9965 from a central console. The dashboard shows real-time connection status, signal strength, data throughput, and device health across the entire vehicle fleet, making it immediately obvious which units are online and which have dropped off. Engineers can push firmware updates, adjust network parameters, and run diagnostics remotely, eliminating the need to recall vehicles to a depot or send a technician to an active road works site. For equipment installed inside sealed vehicle enclosures, physical access often means taking a vehicle out of service — remote management removes that disruption entirely. RMS also supports batch operations, so a fleet-wide configuration change or security patch can be rolled out to hundreds of routers in a single session rather than one unit at a time.
Deployment Value
The combination of the R9965 and RMS delivers a measurable improvement in road worker safety by letting crews operate warning displays from a safe distance, without approaching the carriageway. The external vehicular antenna paired with the router's stable 4G/5G cellular link sustains effective control range well beyond what onboard Wi-Fi alone could deliver, resolving the conflict between worker safety and reliable connectivity. Deployment is fast and requires no civil works or cabling — the system travels with the vehicle and is operational as soon as the crew arrives at a new site, which suits the mobile nature of road maintenance work. Because the R9965 supports both 4G and 5G, operators can deploy in areas where 5G coverage is not yet available and gain the full benefits of 5G throughput and low latency as carriers expand — without replacing any hardware. The five Gigabit Ethernet ports and dual-band Wi-Fi also provide headroom for future needs such as adding cameras, video streaming, or further onboard equipment. Standard cellular connectivity means no specialised radio licensing is required, and fleet coverage can be expanded simply by adding SIM cards. Centralised remote management further reduces lifetime ownership cost by cutting depot visits and on-site interventions.
