The approval of 3GPP Release 16 5G New Radio test cases by Keysight Technologies represents a significant advancement in the validation of multi-antenna systems like MIMO (Multiple Input Multiple Output), which are essential for the efficiency and performance of 5G networks. This development is particularly important for manufacturers and network operators as it ensures that devices are capable of handling complex precoding techniques, which are critical for optimizing data transmission and reception in varied antenna configurations.
The ability to test 16 and 32 element transmitters against these new standards will likely accelerate the deployment of more sophisticated 5G devices, potentially leading to improved network capacity and reliability. This can have a direct impact on the business strategies of telecom companies, influencing their investment in infrastructure and R&D, as well as affecting their competitive positioning in the market.
The validation of Enhanced Power Saving features in 3GPP Release 17 is a critical step towards increasing the energy efficiency of 5G devices. The feature of reducing network paging and increasing the RedCap device discontinuous reception cycles (eDRX) directly contributes to the extension of battery life in 5G devices, which is a significant concern for consumers and enterprises alike. By enabling devices to communicate less frequently with the network and remain in sleep mode for longer periods, manufacturers can offer products that are not only more power-efficient but also more appealing to end-users.
This advancement also has implications for the Internet of Things (IoT) market, where the deployment of a massive number of devices necessitates minimal energy consumption to ensure long-term, sustainable operation. As such, this innovation could lead to a broader adoption of 5G in IoT applications, potentially opening up new business opportunities and revenue streams for companies in this space.
The validation achievements by Keysight Technologies may have a ripple effect on the 5G device market, signaling to investors and stakeholders that the company is at the forefront of 5G testing and development. As Keysight's test solutions become industry benchmarks, there is potential for increased demand for their products, which could positively influence the company's financial performance and stock valuation in the short to medium term.
Furthermore, these developments could also serve as a catalyst for the entire 5G ecosystem, encouraging device manufacturers to hasten their compliance with the latest standards, thus potentially accelerating the overall market growth. For investors, this could translate into a more dynamic and competitive landscape, with opportunities for investment in companies that are quick to adapt to these technological advancements.

Networks based on 5G NR standards support multi-antenna technologies known as MIMO, which improve spectral efficiency and enhance communication. To implement multi-antenna systems, enhanced precoding techniques are applied to the transmitter to map data into the different transmit antennas. The optimal precoding depends on a PMI Codebook value reported by the device, which makes the choice from several precoding options based on its own channel measurements.
As part of Rel-16, the 3GPP added new test cases to validate device performance in multi-antenna systems. Keysight S8705A RF/RRM test solution is the first to gain validation for these new tests, which require unprecedented fading resources to emulate 16 and 32 transmitter connections to use equipment (UE) with 2 and 4 receivers.
Keysight also achieved the following achievements supporting Release 17 (Rel-17) Enhanced Power Saving and RedCap features:
- Validation of test cases verifying UE support of a function that reduces the number of times a device interacts with the network, in order to extend the battery life of devices using the S8705A RF/RRM test solution.
- Validation of test cases ensuring RedCap devices support the Rel-17 increase in the extended discontinuous reception (eDRX) cycle, which is the duration of time a device is in sleep mode in order to extend battery life. This was completed with the Keysight S8704A Protocol Conformance Toolset and activates the RedCap Rel-17 eDRX GCF work item.
Muthu Kumaran, General Manager of Keysight's Device Acceptance Solutions, said: "Enhancing connection performance is a priority for network operators to deliver a better quality of service to final users. Multi-antenna systems are possible with NR and now the first approved tests are brought into the market by Keysight to ensure device’s performance is thoroughly tested. Additionally, validations supporting Rel-17 Enhanced Power Saving features are crucial to drive advancements in 5G NR Rel-17 for commercial 5G NR and RedCap devices market introduction."
