Testing introduction

As a major concern of 5G technology, Sub 6GHz RF test system has been applied in 5G R&D test and 5G terminal type approval of manufacturers, and system capability fully meets the requirements of 3GPP/YD/FCC/NCC/TELEC and other related specifications, and the test results are highly praised. Integrated with instrumentation and wireless testers from many mainstream manufacturers, Ti Group has developed its own intellectual property Sub-6GHz test system, which is efficient, flexible, customized in test mode and adjustable in real time for test cases. Provide high time value for product testing.

5G testing is our advantage

  • Comprehensive 5G infrastructure

    Satisfy the differentiated needs of customers for 5G analog base stations

    5G technology is still in its infancy stage, there are still some compatibility bugs between terminals and analog base stations, which manifests itself in the fact that the same terminal products may have different problems in establishing connection with different base stations. At present, Ti Balun equipped with all mainstream 5G base stations in the market (Keysight E7515B UXM, Anritsu MT8000A+MT8821C and StarPoint SP9500), ensuring 5G project throughput and meeting the differentiated needs of customers.

  • Excellent communications technology team

    Technology upgrading and quality assurance

    In response to the new 5G standards and test technologies, Ti Balun is deeply involved in standards interpretation, testing, projects, certification , and instrumentation. The testing engineers, project managers, certification specialists, and R&D staff are all technicians with more than 10 years of experience in the communications industry. In terms of the definition of test methods and test contents in the standard, we work with the equipment manufacturers to establish the test mode, determine the specific test plan with the world's major notifiedy bodies, work with the terminal manufactures to solve the normal connection of test samples in different test equipment systems, and provide test data in a fast and timely manner for the customer's R&D department to debug, technical improvement and quality assurance.

  • Strong R&D capabilities

    5G test systems meet standards and customer requirements

    Ti Balun had purchased all the equipment that is available on the market. It is designed to cope with products developed by many manufacturers using different platforms and test systems. Relying on Ti Balun's self-developed 2G/3G/4G communication test systems, including EMC& RF, we are able to timely provide 5G test systems that meet standards and customer requirements. As standards are updated and technology is upgraded, 5G test systems will be upgraded simultaneously. The data from Ti Balun's 5G test systems is now recognized by major telecommunications equipment manufacturers and international certification bodies and organizations.
