HMS/Ewon/Red Lion Cellular vs Moxa Non-Cellular Solutions: Which One Fits Your Industrial Needs?
When it comes to industrial automation and remote connectivity, two major players stand out with their differing approaches: HMS (featuring Ewon and Red Lion’s cellular solutions) and Moxa (with its robust non-cellular communication platforms). Whether you’re a plant operator, systems integrator, or an industrial IT decision-maker, the choice between cellular and non-cellular solutions can significantly impact performance, reliability, and scalability of your connected operations.
Let’s dig deeper to understand what sets these companies apart, and how their solutions serve various industrial applications across sectors like manufacturing, infrastructure, energy, and logistics.
Getting to Know the Players
HMS Networks is a global leader in industrial communication and IIoT solutions. Among its portfolio, Ewon and Red Lion stand out for their edge-based 4G LTE/5G cellular gateways and remote access solutions. These devices allow engineers to monitor and control industrial equipment remotely from any part of the world via cloud, mobile apps, or VPN tunnels.
United under the HMS brand, Ewon offers tools like Flexy and Cosy for remote access and edge data management, while Red Lion contributes with rugged LTE routers and industrial automation software that fit harsh environments.
On the other hand, Moxa is known for its time-tested expertise in non-cellular networking technologies. Their product line includes industrial Ethernet switches, serial to Ethernet converters, wireless LAN systems, and real-time protocol converters. These technologies offer ultra-stable and secure data transmission particularly well-suited to stationary or localized industrial networks.
Comparing Technology Approaches: Cellular vs Non-Cellular
To appreciate the value of each approach, you first need to understand what cellular and non-cellular solutions mean in industrial terms.
| Aspect | HMS/Ewon/Red Lion (Cellular) | Moxa (Non-Cellular) |
|---|---|---|
| Connectivity Medium | 4G LTE, 5G, Cellular VPN | Ethernet, Wi-Fi, Serial Interfaces |
| Ideal Use Case | Remote access to mobile, isolated, or hard-to-reach assets | High-performance LAN systems for factories and industrial zones |
| Deployment | Plug-and-play via SIM; can go anywhere with coverage | Requires physical wiring or Wi-Fi infrastructure |
| Latency | Moderate; depending on network strength | Low; real-time data speed |
| Security | Encrypted VPN tunnels, DMZ firewalls | Isolated network layers, IP/MAC filtering |
Pros and Cons: Deep Dive into Each Company’s Edge
Let’s unpack what each technology excels at—and where they might fall short.
HMS/Ewon/Red Lion (Cellular)
Pros:
- Remote Access: One of the biggest advantages of cellular gateways is their ability to enable remote machine monitoring from anywhere.
- No Need for Fixed Infrastructure: Perfect for remote oil rigs, agriculture, water utilities, and OEM equipment in the field.
- Plug-and-Play: Most devices come preconfigured or offer cloud-based provisioning.
- Secure VPN: Ewon’s Talk2M and Red Lion’s cellular routers support secure tunneling and encrypted access.
- Edge Data Processing: Gateways like Ewon Flexy can collect, store, and preprocess data before sending to the cloud.
Cons:
- Coverage Limitations: Performance depends on cellular reception, which varies by geography.
- Subscription Costs: Cellular data plans are recurring operational costs you don’t get with Ethernet.
- Data Throughput: Slower than Gigabit Ethernet or fiber due to cellular latency and bandwidth constraints.
Moxa (Non-Cellular)
Pros:
- Low Latency: Ideal for real-time automation like SCADA, robotic arms, and CNC machines.
- Durability: Their devices are known for operating in extreme industrial conditions.
- High Security: Moxa solutions support network segregation, SCADA firewalls, and IEC security standards.
- Scalability in LANs: You can add hundreds of nodes with switches and protocol converters.
- Lifetime ROI: Once installed, minimal ongoing cost compared to cellular subscriptions.
Cons:
- Lack of Mobility: Devices need wiring or local network access, which is not ideal for portable machines.
- Complex Setup: Human resource to configure and maintain wired infrastructure is typically higher.
- No Direct Cloud Access: Additional layers are needed to push data to cloud or enable remote access.
Application Scenarios and Real-World Use Cases
Let’s bring these technologies to life with real-world examples.
Scenario 1: Agricultural Irrigation Systems in Remote Areas
A smart farm wants to automate irrigation pistons and pumps. With no wired connection available, the farm uses Ewon Flexy gateways to collect sensor data and send alerts to operators via cellular network. The setup provides complete remote automation via Talk2M—without laying a single cable.
Scenario 2: Manufacturing Plant with Real-Time Monitoring
An automotive manufacturer installs Moxa’s managed switches and Modbus gateways to build a deterministic Ethernet network. The ultra-low latency allows real-time machine coordination and predictive maintenance via edge devices. Cellular would simply not deliver the reliability or speed required here.
Scenario 3: Municipal Water Utility Monitoring
Red Lion’s rugged LTE routers monitor pump stations spread across a city. These cellular routers send level/flow data to the central SCADA without involving costly fiber trenching. Operators verify status and control flow remotely from a dashboard.
Scenario 4: Railway Intersection Safety System
Moxa deploys Wi-Fi-based automation nodes with serial data converters to synchronize railway gates and warning lights. Performance is stable even in bad weather, owing to its EMC-rated enclosures and real-time data processing.
Security Comparison
Security is non-negotiable—especially as OT networks become attractive cyber targets. Here’s how both vendors stack up:
HMS/Ewon/Red Lion:
- Multi-layer VPN encryption
- DMZ options for IT/OT segregation
- Cloud authentication via Talk2M
Moxa:
- IEC 62443 compliance
- Role-based access control
- Integrates with firewall/NAT solutions for secure LAN
Each approach has merit, but businesses concerned about real-time threat detection might lean toward Moxa’s protocol-based filtering.
Which One Should You Choose?
Your perfect match depends entirely on your application and connectivity environment. Here’s a simplified rule of thumb:
- Choose HMS/Ewon/Red Lion if your assets are remote or in motion, and you need cloud access, remote control or quick setup.
- Opt for Moxa if you’re centralizing operations, need fast local feedback loops, or are building deterministic and highly secure networks.
Conclusion
In today’s interconnected industrial environments, there is no one-size-fits-all solution. HMS/Ewon/Red Lion’s cellular technologies shine in their ability to bring intelligence to remote or mobile assets with minimal upfront infrastructure. Meanwhile, Moxa’s non-cellular platforms remain the gold standard for high-speed, cybersecure LAN setups in fixed industrial environments.
The good news? These technologies are often complementary. Many enterprises use them together—placing Moxa inside the plant and Ewon/Red Lion outside it—to achieve full-spectrum industrial monitoring and control.
