ALTEN China has established a strong collaboration with a leading global telecommunications company, offering end-to-end engineering solutions for automated testing and product verification. ALTEN China plays a key role in ensuring the quality and on-time delivery of the client’s base stations through thorough testing, tool development, and R&D collaboration. These contributions are vital to helping the client meet stringent product standards prior to mass production, ensuring the delivery of high-quality telecommunications equipment.

Challenges

• The telecom industry faces several key challenges, particularly in ensuring the quality and reliability of products before mass production:
• Complex Testing Requirements: The client’s base stations require a highly specialized testing environment, including both hardware and software components, to ensure they meet stringent quality standards.
• Automated Testing Development: The need to develop automated testing tools that can efficiently test various product modules (TRX, PA, RRH, aging) while maintaining accuracy and consistency.
• Quality Assurance: Ensuring that every base station passes rigorous RF and functional testing to guarantee reliable performance in diverse network environments.
• Timely Issue Resolution: Identifying and fixing product issues early in the development cycle to avoid delays in mass production and ensure products meet client specifications.
• The client required a reliable partner with expertise in automated testing, R&D support, and quality verification to ensure their products met high standards and could be delivered on time.
