The tech world tends to talk about 5G in extremes. On one end, there’s the promise of ultrafast, low-latency connectivity powering autonomous vehicles and remote surgery. On the other, there’s the low-bandwidth world of NB-IoT and LTE-M connecting smart meters and sensors. But between those two poles lies a vast and fast-growing middle ground: 5G RedCap, which more and more often is powering everydayIoT use cases.
While it doesn’t make headlines for record-breaking speeds, RedCap is shaping up to be one of the most practical evolutions of 5G yet. It’s designed for the real world, where billions of connected devices need reliable and power-efficient connectivity while keeping costs down.
What Is 5G RedCap and What Are Its Benefits?
5G RedCap (which stands for reduced capability) was introduced in 3GPP Release 17 as a scaled-down version of 5G New Radio (NR). It runs purely on 5G Standalone (SA) networks, meaning it connects directly to a 5G core without relying on a 4G anchor.
While traditional 5G targets enhanced mobile broadband (eMBB) and mission-critical latency (URLLC), RedCap is optimized for devices that require mid-tier performance, with around 150 Mbps downlink and 50 Mbps uplink.
RedCap achieves this by simplifying the radio design. Instead of four antennas, as in eMBB, RedCap devices can operate with one or two. They use narrower bandwidths (up to 20 MHz in sub-6 GHz spectrum) and omit features like carrier aggregation. The result is a radio module that is smaller and far more power-efficient than standard 5G.
Even as it simplifies some of 5G’s complexity, RedCap retains its biggest advantages, such as:
- Access to network slicing for prioritization and quality-of-service control
- Lower latency than LTE
- Full integration with the 5G core and security stack
- Broad compatibility across global frequency bands
Essentially, RedCap makes the benefits of 5G available to industries that don’t need as high of data rates or extremely low latency but still need to future-proof their technology.
Why Mid-Speed 5G Matters
Much of the IoT ecosystem doesn’t fall neatly into the extremes of 5G’s capabilities. Ultra-high-speed eMBB is overkill for most IoT applications, while massive Machine-Type Communication (mMTC) technologies like NB-IoT or LTE-M are too slow for data-rich or responsive systems.

RedCap bridges the mid-speed gap by offering enough throughput to transmit video and analytics without the cost or power constraints of high-end 5G. This balance makes RedCap particularly ideal for use cases like wearable medical devices and connected machinery. It’s that sweet spot that can extend the lifetime of IoT devices well into the 2030s while still reaping the benefits of 5G. Analysts now project that 5G RedCap and eRedCap adoption will accelerate significantly after 2025, driven by cost advantages and energy efficiency. RedCap is already gaining momentum in routers/CPE, surveillance, and industrial gateways, while eRedCap is expected to enter the market in 2027, replacing many 4G Cat 1 and Cat 1 bis applications. By 2030, RedCap and eRedCap combined are forecast to account for around 50% of all cellular IoT module shipments, with close to 1 billion units shipped globally.
What Are Real-World Mid-Speed IoT Applications?
RedCap is already proving its worth across industries and use cases in which mid-speed, power-efficient connectivity is essential.
- Public safety and video telemetry: body-worn cameras for first responders need stable uplink for real-time video. RedCap provides that bandwidth while preserving power and portability.
- Industrial sensors and connected machinery: in smart factories, machines communicate with other machines through private 5G networks. RedCap allows for real-time status reporting and predictive maintenance without requiring costly eMBB modems.
- Healthcare and eHealth: remote patient monitoring devices transmit continuous vital data with reliability and low latency. Network slicing ensures their data is prioritized over non-critical traffic.
- Smart cities: devices like surveillance cameras and parking meters use RedCap for continuous mid-speed data flow. In China, large-scale deployments have already reached hundreds of thousands of RedCap-connected devices.
- Agriculture: precision farming increasingly uses semi-autonomous machinery that exchanges location and environmental data. RedCap enables efficient, reliable connectivity across wide areas without draining batteries.
Why Is RedCap Beneficial?
RedCap’s ultimate benefit goes beyond the speed 5G provides. It’s really about the practical economics of deployment.
- Lower complexity, lower cost: simplified radios mean reduced bill-of-materials and smaller device footprints. Chipmakers like Qualcomm and MediaTek are already producing RedCap chipsets that cost significantly less than eMBB modules.
- Extended device life: With fewer power-hungry features, RedCap devices should remain operational for 10–15 years in the field, making them ideal for remote assets like agricultural sensors or smart meters.
- Energy efficiency: RedCap consumes up to 50% less power than LTE Cat-4 equivalents under similar workloads.
- Network slicing and SLA control: Operators can dedicate network “slices” to mission-critical IoT traffic, guaranteeing predictable performance even under congestion.
- Longevity through 5G evolution: RedCap sits on the same 5G foundation that will evolve into 5G Advanced, ensuring long-term viability as LTE sunsets post-2030.
In short, RedCap provides a cost-efficient and future-proof path for enterprises to move IoT deployments from LTE to 5G, without adding too much complexity.
The Role of eRedCap and 5G Advanced
We’re already seeing the next evolution of RedCap, enhanced RedCap (eRedCap). It arrives with 3GPP Release 18, the first iteration of 5G Advanced, and will be available commercially by 2026. eRedCap will reduce complexity and cost even more than standard RedCap, supporting throughput closer to LTE Cat 1 bis (around 10 Mbps downlink).
While slower, eRedCap aims to bring 5G reliability and longevity to ultra-low-cost devices, expanding the ecosystem even further. Analysts are already reading the tea leaves on eRedCap and projecting that it’ll help scale 5G to billions of consumer wearables, sensors, and trackers by the late 2020s, accounting for 71% of RedCap module shipments by 2029.

Challenges and the Road Ahead
Despite its promise, RedCap adoption faces several hurdles. Many operators still rely on non-standalone (NSA) 5G networks linked to 4G cores, while RedCap requires standalone (SA) architecture. This dependency means global rollout hinges on network modernization, with full SA coverage expected only by 2026 in most regions.
Early RedCap modules also carry a cost premium, currently priced at two to three times higher than LTE Cat-4. However, costs are projected to decline as second-generation chipsets and economies of scale emerge in 2026.
Momentum is building active RedCap trials span 21 countries, and commercial launches have begun in Asia and North America with Europe following closely. Looking ahead, Release 18 eRedCap (planned for 2027) will further reduce complexity and cost, accelerating adoption for ultra-low-power IoT applications.
The Future of Everyday 5G
The next chapter of IoT connectivity won’t be written by headline-grabbing gigabit speeds. It will be defined by technologies like RedCap: solutions that deliver just enough speed, just enough power efficiency and just enough cost optimization to make 5G viable for billions of everyday devices.
As enterprises phase out LTE and transition toward 5G-Advanced and private-5G networks, RedCap provides a scalable, affordable bridge. Whether it’s a health monitor, a wearable, an industrial sensor or a connected camera, mid-speed 5G ensures the connected worlds runs not just faster, but smarter.
With module production now entering the market, and early consumer/enterprise devices on the horizon, RedCap is stepping out the shadows becoming the practical connectivity layer for mass-market IoT. Product leaders must position around this shift: defining device architectures, power budgets, module ecosystems and network partnerships accordingly.
