Industrial Connectivity
Solution Architectures

E-Lins solution architectures are practical, repeatable network architecture patterns for connecting industrial equipment, field devices, remote infrastructure, and cloud platforms โ€” from the device layer to the network layer to your operations platform.

Connected Industrial Architecture

How Do Field Devices Connect to the Cloud?

Connect distributed industrial devices and remote assets through secure cellular, Ethernet, and edge connectivity. This is the master architecture behind every E-Lins deployment โ€” the same four-layer pattern, tuned per industry: sense and control at the edge, connect through an E-Lins router or gateway, transport over 4G/5G or wired networks with VPN security, and operate from cloud or NMS.

An E-Lins industrial connectivity architecture defines how field devices, edge connectivity and cloud platforms interact across cellular, Ethernet and VPN layers. One architecture, many industries โ€” the layers stay the same, while interfaces, protocols and redundancy options adapt to each deployment.

Product Roles

Which E-Lins Product Fits Your Architecture?

Map each layer of your architecture to the right product family. This is the bridge from architecture design to product selection โ€” start from what your network must do, then pick the device that does it.

Your RequirementRecommended ProductWhy It Fits
Remote cellular networking Industrial Cellular Router Routing, VPN, Wi-Fi and dual-SIM failover in one rugged device โ€” the connectivity core of most architectures.
Protocol / device integration IoT Gateway RS232 / RS485, Modbus, MQTT and DI/DO bridge field protocols to IP networks and cloud platforms.
Add cellular connectivity to existing equipment Industrial Modem A simple, reliable cellular uplink for controllers, panels and kiosks that already handle the application logic.
Connect multiple Ethernet devices Industrial Ethernet Switch Managed and PoE switches aggregate cameras, PCs and controllers before the uplink โ€” e.g. in surveillance architectures.
Local control / I/O at the edge Industrial Controller Edge logic, digital I/O and protocol handling directly at the site โ€” even when the cloud link is down.
Centralized device management E-Lins NMS Monitor, configure and update the entire fleet from one dashboard โ€” SaaS or on-premise, with API access.

Architecture Basics
What is an industrial connectivity solution architecture?
+

It is a repeatable network design pattern: which field devices connect to which E-Lins router or gateway, how traffic travels over 4G/5G, Ethernet or VPN, and where it lands โ€” cloud, NMS or SCADA.

This page documents six such patterns โ€” three core topologies and three industry-tuned variants โ€” so you can start from a proven design instead of a blank page. Each pattern card above includes a one-paragraph summary you can quote directly in your own design documents.

How do I choose between an industrial router, gateway and modem?
+

Router for the network core, gateway for protocol integration, modem when an existing controller just needs a cellular uplink.

Routers handle routing, VPN, Wi-Fi and dual SIM; gateways translate field protocols such as RS485, Modbus and MQTT; modems provide the simplest transparent cellular connection. The requirement-to-product table in Section 03 maps each layer of your architecture to a family.

Can these architectures work without wired internet at the site?
+

Yes โ€” every pattern supports 4G LTE and 5G cellular uplinks, with optional dual-SIM failover.

Where Ethernet or fiber exists, it can be the primary link with cellular as automatic backup. Link-detection policies switch over in seconds, and the NMS reports the failover event.

Security & Customization
How is security handled across the architecture?
+

In layers: VPN tunnels between site and platform, per-device firewall, certificate-based NMS management, and 10+ years of firmware security updates.

Supported VPN types include IPsec, OpenVPN and WireGuard; access control lists and port policies are configured per device, and firmware patches are pushed over the air.

Related: VPN / network security considerations

Can E-Lins customize an architecture for my project?
+

Yes โ€” hardware, firmware and enclosures can all be adapted, from MOQ 50 units with full NDA protection.

Our engineers review your topology, interfaces, power and environmental requirements, then propose a modified design. Typical custom development runs 14โ€“20 weeks from concept to mass production.

Which industries do these architectures cover?

The same patterns span smart city, industrial automation, energy & utilities, transportation, agriculture, video surveillance, remote monitoring, EV charging, mining and ATM / banking.

Deployment Considerations

Key Considerations for Industrial Connectivity

Good architectures are designed around constraints, not products. These are the ten factors our engineers check first when reviewing a deployment โ€” work through them before finalizing any architecture.

๐Ÿ“ถ
Cellular Coverage
Survey signal strength and band availability at each site; check antenna options.
๐Ÿ”„
SIM / Dual SIM
Single or dual carrier? Decide failover policy before deployment.
๐Ÿ”Œ
Ethernet Requirements
Port count, PoE budget, VLANs, managed vs unmanaged switching.
๐Ÿ”ฉ
Industrial Interfaces
RS232/RS485, DI/DO, CAN โ€” match the device to your field equipment.
๐Ÿ”‹
Power Supply
9โ€“36V DC ranges, PoE input, surge protection, backup power.
๐ŸŒก๏ธ
Environmental Conditions
-40ยฐC to +70ยฐC, IP67/IP68 enclosures, vibration, humidity.
๐Ÿ”
VPN / Network Security
IPsec, OpenVPN or WireGuard tunnels, firewall policies, certificates.
๐Ÿ–ฅ๏ธ
Remote Management
NMS onboarding, zero-touch provisioning, OTA firmware, alerts.
๐Ÿ“Š
Scalability
Plan for 10ร— device growth โ€” addressing, NMS capacity, templates.
๐Ÿ›ก๏ธ
Redundancy / Failover
Dual SIM, wired + cellular backup, link-detection policies.
