Engineering, testing, porting and AI
TechPhosis provides five categories of engineering services. First, RAN and Core R&D — covering 5G RAN, 5G Core, UE software, edge computing, and radio design. Second, Platform Porting and Integration — across Intel, NXP, Marvell, ARM, NVIDIA, AMD, and RISC-V platforms. Third, Testing and Validation — functional, regression, performance, protocol conformance, and O-RAN compliance testing. Fourth, AI and ML Optimization — native AI integration into 5G stacks, intelligent automation, and predictive analytics. Fifth, India Market Entry — ODC setup, engineering teams, compliance, localization, and go-to-market support.
TechPhosis has extensive hands-on porting experience across Intel x86, Intel FlexRAN, NXP Layerscape (LX2160, LX2080, LX2088, LS1046, LA1200 series), Marvell, ARM Ampere, NVIDIA Grace Hopper, AMD, and RISC-V. We also support FPGA acceleration and GPU acceleration where applicable, as well as virtualized and cloud-native deployment environments.
Our testing capabilities span both proprietary frameworks we develop in-house and leading industry tools. We have hands-on experience with QXDM, VIAVI TM500, Amarisoft, Simnovus, Spirent, and NetHawk Protocol Analyzer. We also develop custom automated test frameworks integrated with CI/CD pipelines, automated regression suites, and AI-assisted test analysis tools.
We offer both. Many customers engage TechPhosis for a specific phase — such as platform porting or testing — while others opt for turnkey development where we manage the complete engineering lifecycle from specification to deployment. Our modular engagement model allows customers to bring us in at any stage of the product lifecycle and scale involvement up or down as needed.
Yes. TechPhosis provides protocol conformance testing and O-RAN Alliance compliance validation services. We validate across key interfaces including F1, E1, E2, and O1, and conduct end-to-end validation across terrestrial, OTA, and satellite links. We also support 3GPP Release 18 and 19 feature validation. Our Lab as a Service offering provides a fully managed environment for device certification and compliance testing.
