5G Redcap Will Pave the Way for Mass IoT Deployment

Global cellular IoT module shipments are expected to surpass 1.2 billion units by 2030. With a compound annual growth rate (CAGR) of 12 per cent according to Counterpoint Research.  

This will mainly be driven by 5G, NB-IoT and 4G Cat-1 technologies. Including Machine-to-Machine (M2M) IoT applications to support cost effective, lower-power industrial, commercial and consumer-facing IoT projects.

Momentum of 5G

The latest Ericsson Mobility Report highlights that growth in services and subscriptions of 5G-capable devices is exceeding that of 4G Long-Term Evolution (LTE). Its momentum has even outpaced the transition between 2G to 3G. 

In Q2 of 2022, this translated to 70 million new 5G subscriptions added globally. This brought the total number of 5G subscriptions globally to 690 million.

This growth is expected to continue, with an expected 4.4 billion 5G subscriptions by 2027. 

5G New Radio Reduced Capacity (NR REDCAP) – Bridging the Gap

As enterprises start to reap the benefits of IoT, more large scale deployments will follow suit. Yet many IoT use cases do not require high-performance features that smartphones do.

This is where a light version of the 5G standard, 5G NR REDCAP, comes into play. Bridging the gap between efficient LPWA Networks and critical IoT features.

This technology makes it ideal for broader adoption of 5G in use cases. Including pressure sensors, humidity and temperature sensors, actuators and more.

These need higher bandwidths what NB-IoT or 4G Cat-1 technology can provide, but require lower data rates and latency.

Without 5G NR REDCAP, the easy solution would be to connect directly to an existing LTE network and use data at LTE speeds as needed. For a deployment that requires connecting and powering tens of thousands of devices, costs quickly become inhibitive.  

Comparing enhanced mobile broadband (eMBB) and ultra-reliable and low latency (URLLC), 5G NR REDCAP has reduced features. It is essentially an optimized design for mid-tier IoT use cases. Let’s take a closer look at some of these characteristics.

5G NR REDCAP Features

Devices can efficiently support 150 Mbps and 50 Mbps in the downlink and uplink. This means that devices connected to the NR REDCAP channels could enjoy similar bandwidth as a standard 4G LTE connection, without adding a significant load to the network.  

Additional features include: 

  • narrower bandwidths – 20 MHz in sub-7 GHz or 100 MHz in millimeter wave (mmWave) frequency bands; 
  • a single transmit antenna; 
  • a single receive antenna (2 antennas being optional); 
  • support for half-duplex TDD (instead of FDD); 
  • lower-order modulation (256-QAM being optional); and 
  • support for lower transmit power

These allows for devices to operate on batteries for years without charging.

With access to a much higher bandwidth and ultra-low latency, NR REDCAP offers a new wave of possible IoT applications. Meaning you stand to benefit from richer insights, without incurring cost, power requirements, and complexity of high-end 5G devices.

Use Cases & Applications
Industry 4.0 is expected to be a significant adopter of 5G REDCAP technology

5G NR REDCAP will see the widespread adoption of 5G across intelligent IoT applications. Predominantly in industrial, logistics and supply chain, retail (PoS), and telematics segments. 

The flexibility and scalability of 5G NR REDCAP makes it possible to introduce timely enhancements. Which means you stand to benefit from increased efficiency, while reducing operational costs (e.g. maintenance).

This will pave the way for new use cases not currently served by current NR specifications. Catalyzing the next wave of IoT transformation.
