Calnex and Viavi Partnership

Simplifying Open RAN Conformance and Performance with Comprehensive
Pre-Certification Testbeds

Calnex Solutions plc (AIM: CLX), a leading provider of test and measurement
solutions for the global telecommunications and cloud computing markets, has
partnered with VIAVI Solutions Inc. (VIAVI) (NASDAQ: VIAV) to provide a suite
of test solutions for the comprehensive testing of Open RAN products across
the protocol, signal and timing domains. These testbeds simplify and reduce
the cost of developing an in-house Open RAN testing for pre-certification
validation and can be set up immediately with no debugging.

The shift to Open RAN and AI-RAN in 5G and 6G systems is opening the telecom
infrastructure market to a greater number of companies, including startups and
university spinouts. While this has the potential to accelerate innovation,
multivendor ecosystems require strict adherence to performance, security,
interoperability and reliability standards. Although final O-RAN ALLIANCE and
3GPP certification takes place at official labs, pre-testing is essential to
ensure success and avoid the costs of failing.

Through the Calnex and VIAVI partnership, manufacturers of O-RU, O-DU and O-CU
equipment can access three testbeds immediately. The integrated systems from
Calnex and VIAVI allow for full O-RAN and 3GPP conformance testing, while also
emulating realistic network impairments like jitter and delay. This enables
the rigorous testing of key functions.

Tommy Cook, Chief Executive Officer and founder of Calnex, said: "O-RAN has
opened up traditional telecoms architecture to new market entrants, creating a
widening pool of organisations requiring telecoms test solutions. We have
experienced success with our product offerings in recent years as a result of
the O-RAN initiative, and with this partnership with VIAVI, a global leader in
communications test and measurement technologies, we hope to build on that yet
further.

"Companies urgently need in-house labs to validate their Open RAN systems, but
establishing them has traditionally required equipment from multiple vendors
and can take several months of debugging to ensure interoperability. VIAVI and
Calnex's offerings are highly complementary, and we've undertaken the complex
integration work to create these first-of-their-kind comprehensive testing
systems and eliminate the issues that have plagued many developers. Early
customer feedback has been positive and we look forward to maximising the
partnership's potential across key regions."

Ian Langley, Senior Vice President and General Manager, Wireless Business Unit
of VIAVI, said: "During the development phase, many O-RUs are only tested with
a single O-DU/O-CU vendor, which results in failure under real-world network
conditions. This issue is compounded as the industry lacks tools to emulate
realistic fronthaul conditions. Our partnership with Calnex puts these tools
directly into the developers' hands to vastly speed up and simplify Open RAN
test lab setup."
