What projects are you currently working on?
Since 2018, we’ve joined the formal IOP (Interoperable Prototype Test) co-hosted with UPF60 and contributed the test result to expedite the official adoption of the CTES service and asset tracking profile as early as possible.
Why has GCT decided to be so involved with the testing process, including being the local host for the upcoming UPF? How has the testing benefited GCT Semiconductor?
GCT Semiconductor has chosen to exploit this chance for advancing the standardization process. After participating at UPF60, GCT has been asked to serve as the local host of UPF63, and we willingly volunteered to help more companies building with Bluetooth in Korea to join the second and last event in Seoul.
Why is interoperability so critical for this project?
Although a new version of the Bluetooth® Core Specification that supports direction finding was released, it is not the end of the overall project. It is just a beginning. Many services and profiles must be refined through interoperability testing between vendors. That is why TTA, one of the early associate members of Bluetooth SIG and a Bluetooth Qualified Testing Facility (BQTF) in Korea, has teamed up a special DF-IOP task force in preparation of the two-year-long test event in Seoul, and GCT accepted the request to join the task force without any hesitation. We’d like to encourage more members to gather for interoperability testing.
What is the significance of the testing program from your perspective?
In the Bluetooth standardization process, voting cannot be held without undergoing the IOP, which means that tentative unanimous agreement on the written specification cannot guarantee the final adoption of a new technology. This process shapes the idea, making it more concrete and practical. All participants must keep in mind the implementation hurdle, competing with but also helping other members. The IOP serves as a concentric force to various Bluetooth device vendors, assembling them to gather against other competing standards launched on the 2.4GHz ISM band.
Can you talk more about the need for people to get involved with the specification development and testing process?
Bluetooth® is one of the most successful wireless technology standards. Getting involved in the specification and testing process before the announcement of the standard will make participants more agile to the trends of the market needs and new technology.
