Early functional test
TM500 delivers early functional base station development, where most engineering resource is allocated for writing code and developing specific elements of functionality. As your engineering teams adopt “shift-left” development and testing methodologies providing the benefit of detecting problems early in the development cycle and save time and money by avoiding the need for expensive rewriting of software, VIAVI offers the best debugging., logging, monitoring and measurement test tools for the exact stage of development enabling you to maximize your ROI.
System integration, capacity, performance and regression test
As your project continues through the development lifecycle the test requirements become more complex however, there are usually less engineering resources allocated to tasks such as system integration or performance testing. At this stage where feature combinations with increased numbers of carriers and subscribers are required, the TM500 Family offers provides a comprehensive suite of feature interaction and application capabilities at scale while still maintaining performance targets. This gives you the reassurance and support of an industry standard test tool with best in class and automation capabilities when engineering resource is at a premium.
TM500 for O-RAN
Over many years of working with all major NEMs and small cell manufacturers, VIAVI has built a reputation as a trusted supplier of leading-edge cellular test equipment. Our flexible approach and ability to accommodate different customer requirements allows to support the various options and configurations different operators require in order to deploy O-RAN solutions. VIAVI is part of O-RAN and is involved in developing specifications. This is important particularly in supporting multiple vendors with different vendor specific requirements. TM500 plays an important role in O-RAN Alliance Events across the globe including displaying the latest Proof of Concepts in O-RAN alliance Plugfests.
As O-RAN continues to evolve, VIAVI is well placed to align with its objectives on virtualization, interoperability and the use of low cost, off-the-shelf platforms.
Testing the O-DU
TM500 O-DU Tester is an extension of the TM500 which has an unparalleled global support footprint to assist customers in expediting delivery and deployment around the world. This solution has already been used early on in End-to-End O-RAN performance tests to benchmark the O-RAN network against traditional 5G gNBs in a real customer environment. Though extensible to leverage the advantages of the TM500 as mentioned earlier, the TM500 O-DU tester is also flexible to test certain O-RAN functionalities that do not require the TM500, thereby enabling customers to manage costs as the complexity of test evolve.
Access to leading TM500 3GPP features over O-RAN: With seamless access to already leading 3GPP 5G features supported over RF, this means that customers can expect no performance compromises with feature combinations. Moreover, customers can re-use TM500 functionality and features already purchased thereby lowering costs of ownership and extending product use for other applications. Existing features and capabilities such as the latest high order Carrier Aggregations and MIMO, TM500 capacity, mobility and interoperability with legacy RATs like 4/4.5G can be re-used. The TM500 5G already supports today 1000’s of UEs with a rich KPI set for network performance testing over RF.- 5G functionalities supported over RF can be accessed over O-RAN as it matures. This is important to operators for End-To-End network performance testing and inter-operability with 4/4.5G where the TM500 clearly leads with its continued parallel investment in both 4/4.5/5G .- All mobility scenarios are supported over 5G key as the deployment scenarios become more complex.
Testing the O-RU
The TM500 O-RU Tester covers a wide range of test capabilities, allowing customers to ensure conformance, inter-operability and performance testing including real-time generation of the O-RAN Control/User/Synchronization/Management plane messaging for the IQ data stream. The TM500 O-RU Tester supports inter-operability validation for different vendor O-RUs, addressing key challenges seen with testing within the O-RAN test framework.
The TM500 had been the defacto industry-standard in network test since 3G and it showcased a 5G proof of concept back in 2013. TM500 remains at the forefront of technology with an industry leading 3GPP and O-RAN roadmap with parallel in investment in 4/4.5/5G and O-RAN.
VIAVI remain on the cutting-edge of network development and has helped the industry test and ready networks from lab to field during earlier standards transitions, TM500 will play a critical role in the testing and development of 6G over the next decade.
6G R&D must start now. It will require a new mindset and flexible, lab-based methodologies, which, working with a partner like VIAVI, will allow NEMs and service providers to easily and cost-effectively make the journey from 4.5G, 5G, all the way through to 6G. VIAVI continues to work with leaders in technology research creating proof of concepts for next generation networks.
VIAVI partners with our customers and other technology leaders to ensure we deliver the ideal solutions.
