As cellular networks evolve toward 5G, organizations deploying connected infrastructure face a challenge: not every application needs the full complexity and cost of high-performance 5G. Many industrial and enterprise IoT deployments require reliable connectivity, moderate throughput, long lifecycle support, and efficient power consumption.
This is exactly the problem 5G RedCap (Reduced Capability 5G) was designed to solve.
The Digi IX25 cellular router platform includes support for 5G RedCap, enabling organizations to adopt a streamlined form of 5G optimized for real-world IoT deployments. By combining RedCap connectivity with rugged industrial design, edge computing, and centralized management through Digi Remote Manager, Digi IX25 provides a future-ready connectivity solution for distributed infrastructure, industrial automation, and enterprise edge networks.
Why 5G RedCap Matters for Real-World IoT
Traditional cellular technologies create a gap in capability for many IoT applications.
- While LTE is sufficient today for a range of industrial applications, it will sunset in the foreseeable future. This means enterprises deploying new solutions are evaluating next-generation 5G devices.
- However, full 5G eMBB supports extremely high data rates but introduces higher cost, power consumption, and device complexity.
5G RedCap bridges this gap.
Standardized in 3GPP Release 17, with further enhancements defined in Release 18, RedCap simplifies the 5G device architecture by reducing features such as antenna count, bandwidth, and RF complexity while still leveraging the core benefits of the 5G network. The result is a connectivity tier designed specifically for mid-range IoT applications that need more capability than LTE but do not require full 5G performance.
For industrial and enterprise deployments, this translates into several advantages:
- Lower device cost
- Reduced power consumption
- Simplified integration
- Future-proof deployments
Digi IX25: A Platform Built for 5G RedCap
Digi IX25 is a rugged industrial cellular router platform designed to support LTE, 5G RedCap, and full 5G eMBB in a unified architecture.
By supporting multiple cellular technologies in one platform, Digi IX25 allows organizations to deploy connectivity tailored to each application’s needs while maintaining a consistent hardware and management environment.
Key capabilities include:
- Industrial-grade design for harsh environments
- Edge computing for local data processing
- Secure routing and VPN connectivity
- Centralized device management via Digi Remote Manager
- Flexible connectivity for public and private cellular networks
This approach enables organizations to standardize on a single platform while adapting connectivity to evolving network technologies.
The IX25 product family includes variants for LTE, 5G RedCap, and 5G eMBB, allowing customers to choose the appropriate level of connectivity for each deployment.
How RedCap Reduces Complexity and Cost
One of the primary advantages of 5G RedCap is reduced device complexity.
Full 5G eMBB implementations typically support higher-order MIMO configurations — commonly 4×4 at sub-6 GHz — to achieve peak throughput.
In contrast, 5G RedCap devices are defined with a reduced receive antenna configuration — as few as one antenna for the most constrained implementations, with two being the practical baseline for most deployments. This simplified architecture reduces:
- Hardware complexity
- Power consumption
- Device cost
- Installation overhead
For organizations deploying thousands of connected endpoints across distributed infrastructure, these cost efficiencies can significantly reduce total cost of ownership.
Because RedCap requires a 5G Standalone core, deployments benefit from modern network capabilities including network slicing, lower latency, and stronger security compared to legacy LTE networks.
Future-Proofing IoT Deployments
One of the biggest strategic considerations for IoT connectivity is longevity.
Industrial infrastructure, utilities systems, and transportation networks often remain deployed for 10–20 years or longer. As carriers gradually transition spectrum away from LTE toward 5G, organizations must ensure their connectivity strategies align with long-term network evolution.
5G RedCap offers a practical migration path.
Because RedCap is built on the 5G Standalone architecture, organizations can take advantage of modern network capabilities — including network slicing and cloud-native orchestration — while maintaining the simplicity needed for large-scale IoT deployments.
With LTE sunset timelines expected in the 2030–2035 timeframe, adopting RedCap today helps ensure new deployments remain compatible with the networks of the future.
Real-World Use Cases for Digi IX25 RedCap Deployments
The Digi IX25 platform enables RedCap connectivity across a wide range of industries and applications.
Industrial IoT and Industry 4.0
Manufacturers rely on cellular connectivity for predictive maintenance, machine telemetry, and distributed automation systems. Edge computing capabilities in IX25 routers allow data to be processed locally before being transmitted to cloud platforms, reducing latency and enabling near real-time data processing.
Utilities and Critical Infrastructure
Utilities deploy cellular routers for SCADA systems, remote monitoring, and grid automation. RedCap provides the throughput needed for multi-sensor telemetry — with 3GPP Release 17 defining a baseline of approximately 85 Mbps downlink and 50 Mbps uplink — while maintaining reliable connectivity in remote installations.
Oil and Gas Operations
Pipeline monitoring, compressor station automation, and remote asset management require secure, always-available connectivity in harsh environments. Industrial cellular routers enable real-time monitoring and control of distributed infrastructure.
Distributed Enterprise and Retail
Retail chains, kiosks, and branch locations use cellular routers for point-of-sale systems, digital signage, and failover connectivity. RedCap delivers sufficient bandwidth for business operations without the cost of full 5G deployments.
Smart Cities and Transportation
Traffic systems, surveillance infrastructure, and intelligent transportation networks benefit from reliable cellular connectivity for sensors, cameras, and control systems.
Edge Intelligence at the Network Edge
Connectivity alone is not enough for modern IoT deployments.
Digi IX25 integrates edge computing capabilities that allow organizations to collect, process, and analyze data closer to the source. This approach reduces latency, improves reliability, and minimizes bandwidth usage by filtering and processing data locally before sending it to the cloud.
Edge computing also improves security and operational resilience by allowing critical applications to continue functioning even if cloud connectivity is temporarily interrupted.

Digi IX25 5G RedCap FAQs
Why would an organization choose 5G RedCap instead of 5G eMBB for industrial deployments?
Many industrial IoT applications do not require the extremely high throughput or complex radio capabilities of 5G eMBB. Applications such as SCADA telemetry, distributed sensors, remote monitoring, and branch connectivity typically require reliable connectivity and moderate bandwidth rather than multi-gigabit speeds.
