This post delves into the implementation, challenges, and advantages of 5G Internet of Things (IoT) connectivity using NR-Light technology. NR-Light, also referred to as New Radio Light, is an advanced technology that enables reliable and low-latency communication for IoT devices. We will explore a real world scenario where NR-Light was deployed to enhance connectivity and facilitate advanced IoT applications.
NR-Light, also known as RedCap (reduced capability), is the industry solution for mid-tier 5G IoT connectivity. It bridges the gap in capabilities and complexity between high and low performance IoT devices available in the current 5G landscape.
NR-Light, introduced in 3GPP Release 17, aims to reduce the complexity and cost of 5G devices, minimize power consumption, and maintain data speeds comparable to LTE Cat-1. While it offers significant cost reductions, power savings of over 90%, and adequate data speeds.
The demand for 5G IoT connectivity is essential in facilitating machine communications and supporting a wide array of IoT applications within connected industries. While the current focus of 5G IoT has primarily centred around low-complexity and high-performance devices, there is an evident need to cater to mid-tier devices, including wearables, health monitors, vehicle trackers, and industrial sensors.
To effectively address this demand on a large scale and for a sustainable duration, it is imperative to develop a new category of 5G-native IoT solutions.
Despite the potential benefits, the implementation of 5G IoT connectivity using NR-Light poses certain challenges:
Establishing a 5G NR-Light network infrastructure requires strategic positioning of mmWave base stations throughout the city, presenting logistical and cost challenges.
Solution: A meticulous planning process and collaboration with local authorities can help overcome logistical challenges. Strategic deployment plans considering optimal coverage and cost-effectiveness should be devised.
Integrating existing IoT devices with the NR-Light network involves upgrading devices to support 5G connectivity, which may pose compatibility and cost challenges.
Solution: Develop comprehensive upgrade strategies, including firmware updates and hardware enhancements. Collaboration with device manufacturers to ensure compatibility and cost-effective upgrades is essential.
Protecting the IoT network from potential cyber threats demands robust security measures, raising concerns about data privacy and scalability.
Solution: Implement advanced encryption protocols, multifactor authentication, and regular security audits. Establish scalable security frameworks to adapt to the growing network and evolving cyber threats.
Some patent publications like US20230035261A1, US20220400511A1, etc., enlighten the NR-Light concept for IoT devices.
The case study involves examining how a smart city infrastructure provider overcame the connectivity challenges by implementing 5G IoT connectivity with NR-Light technology.
Implementation Process
Fun Fact
Ericsson highlighted that the 3GPP Release 17 work on the support for reduced capability NR devices is an important step to further expand the addressable market of 5G NR. “Some of the wearable and video surveillance use cases are currently addressed by LTE-based solutions. NR RedCap offers a path for migrating from LTE to NR for these use cases. Such a migration path is important as it can accelerate the spectrum refarming from LTE to NR a number of years down the path.
The implementation of 5G IoT connectivity with NR-Light technology yielded several significant benefits:
NR-Light’s utilisation of the mmWave spectrum provided considerably higher bandwidth compared to traditional IoT connectivity solutions, facilitating the seamless transmission of large amounts of data generated by IoT devices.
NR-Light’s ultra-low latency capability enabled real-time communication between IoT devices and the central management system, resulting in near-instantaneous responses and enhancing the efficiency of IoT applications.
NR-Light’s reliability ensured consistent connectivity for IoT devices, minimizing downtime and optimizing the overall performance of the network.
5G IoT connectivity using NR-Light allowed the infrastructure provider to leverage advanced IoT applications such as real time monitoring and control of smart city infrastructure, predictive maintenance, and improved data.
In addition to the above, one of the major players “Qualcomm” is currently in the process of enhancing its Snapdragon chipsets to cater to the next generation of 5G devices.
One significant addition is the “Snapdragon X35”, the world’s first 5G NR-Light modem, which offers a cost-effective design with optimized power efficiency, thermal performance, and a reduced footprint. It is specifically designed for a new wave of 5G devices like smartwatches, XR glasses, health monitors, surveillance cameras, and fixed wireless customer premises equipment (CPEs).
The Snapdragon X35 5G Modem-RF System incorporates advanced modem-RF technologies that significantly reduce power consumption, enhance 5G coverage, lower latency, improve battery life, and increase uplink speeds.
By offering a cost-effective solution and bridging the gap between extreme 5G capabilities, the Snapdragon X35 provides a device platform suitable for mid-tier use cases. It provides a long-term migration path for replacing LTE CAT4+ devices, ultimately promoting the adoption of 5G and facilitating a faster transition to a unified 5G network.
Future Outlook
Moving forward, we will remain vigilant in monitoring the advancements in technology and patent documents in this emerging field. As the applications of this technology gain more traction in the consumer market, we will closely observe its progress.
