Industrial router manufacturer Tespro has a front-row seat to the biggest shift in utility networking in decades: the steady move from legacy GPRS links to resilient 4G and 5G. Utilities, campuses, and smart city teams want real-time data, lower field visits, and secure cloud connectivity. As an Industrial router manufacturer, we built our portfolio to make that transition simple, safe, and cost-effective - without interrupting the meters, RTUs, sensors, and controllers you already rely on.
Why Utilities Are Moving From GPRS To 5G
GPRS proved its value for early AMI/AMR rollouts. But today's grids, buildings, and city assets generate more data and require faster decisions. 4G and 5G deliver higher bandwidth and lower latency for analytics, remote control, and firmware updates. At the same time, NB-IoT remains a perfect fit for low-power endpoints. A practical path forward is a mixed fleet: keep low-rate assets on GPRS or NB-IoT where needed, and upgrade critical nodes to 4G/5G for real-time visibility. As an Industrial router manufacturer, Tespro enables this hybrid path with multi-bearer routers that speak GPRS, 4G, 5G, and NB-IoT - and fail over between them automatically.
What Utility Networks Need From an Industrial Router Manufacturer
Utilities operate in the real world - hot, cold, dusty, and remote. They need equipment that just works, year after year. Here is what we hear most often and how we respond:
✓ Reliable, continuous links
- Dual-SIM standby and triple backup switching (wired/Wi-Fi/4G) keep data flowing when a path fails.
✓ Secure, cloud-ready connectivity
- Public LTE or VPDN/private APN selections partition traffic and protect essential data.
✓ AMI/AMR integration
- Smooth ingestion from meters and concentrators into head-end systems and the cloud.
✓ Energy-efficient operation
- Low current profile extends backup windows at remote sites.
✓ Simple deployment at scale
- Standard interfaces and dependable performance shorten install cycles and training.
Inside Tespro's Cellular Core: From GPRS and NB-IoT to 4G/5G
As an Industrial router manufacturer, we engineer for continuity first. Our routers support GPRS, 4G, 5G, and NB-IoT so you can connect legacy and next-gen assets on one platform. Dual-SIM standby lets you place two carriers in a single device. If the primary link drops, the router moves to the secondary SIM or to wired/Wi-Fi as required. This automatic failover keeps AMI/AMR sites reporting without manual intervention.
On the LAN side, you can attach field devices over multiple Ethernet ports (up to five auto-adaptive 100 Mbps ports) and Wi-Fi 802.11n up to 300 Mbps for local maintenance or backhaul relief. Real-time data transmission reduces operational effort: no more waiting for daily dial-ups; no more blind spots when weather or traffic spikes load. Utility teams see network status in minutes, not days, and can act before small issues become outages.
Rugged By Design: Power, Temperature, and Installation That Fit The Field
Field conditions are unforgiving. Tespro routers are built for it. The metal enclosure and industrial-grade protection handle shock and vibration. Operating temperature spans from -40°C to 75°C with 5–95% non-condensing humidity tolerance, so roadside cabinets and plant rooms are both in scope. A wide-voltage DC input (12–36V) matches common utility power rails, and dual power options (DC jack and terminal) add redundancy. Typical current consumption stays under 400 mA to minimize load on backup batteries and solar arrays.
Installation is fast. The compact footprint - about 93 × 118 × 24 mm (without antennas) - fits tight spaces, and DIN-rail mounting keeps panels clean and serviceable. For teams upgrading from legacy modems, standardized interfaces reduce rewiring and shorten commissioning windows. As an Industrial router manufacturer, we obsess over these details because they save you hours on every cabinet.
Smarter Operations: Security, Continuity, and Management That Reduce OpEx
Continuity That Never Sleeps
- Triple backup switching and dual-SIM standby keep telemetry streaming during carrier maintenance, fiber cuts, or RF congestion. With cellular and Wi-Fi options, you can choose the best path per site and change it later without a truck roll.
Security Built for Critical Infrastructure
- Connectivity via public LTE or VPDN/private APN segments helps keep OT traffic isolated from the public internet. Combined with hardened hardware and interoperable interfaces, it delivers a secure, continuous bridge connecting field devices and the cloud.
- Real-time visibility modernizes everyday work. Teams can push configuration updates in minutes, schedule burst packets to make efficient use of airtime, and reduce site visits. For AMI/AMR, more frequent reads enable leak detection, outage mapping, and faster billing cycles. For campuses and smart cities, higher-frequency data supports energy optimization and predictive maintenance. The result is fewer surprises and a clear line of sight from the edge to your control room.
Proof Points That Matter
- ✓ Multi-bearer support: GPRS, 4G, 5G, NB-IoT for hybrid fleets
- ✓ Wi-Fi 802.11n up to 300 Mbps for local access
- ✓ Up to 5 auto-adaptive 100 Mbps Ethernet ports
- ✓ Operating temperature: -40°C to 75°C; humidity 5–95% non-condensing
- ✓ Wide-voltage input 12–36V; dual power inputs for redundancy
- ✓ Compact 93 × 118 × 24 mm, DIN-rail mount
- ✓ Current consumption under 400 mA for energy-efficient sites
