Qualcomm
The world's first 5G baseband chip comes from the old chip giant - Qualcomm of the United States.
Qualcomm released the X50 5G baseband chip in October 2016. At that time, the global 5G standard had not yet been established.
Due to the early launch, the X50 was weak in performance and functionality, and was mainly used in some test or verification scenarios. No mobile phone manufacturer dares to use this base band to mass-produce 5G mobile phones. In February 2018, Huawei released its first 5G baseband - Balong 5G01 (Balong 5G01) - at MWC Mobile World Congress in Barcelona. Huawei calls it the world's first 5G baseband compliant with the 3GPP 5G Protocol Standard (R15).
However, this 5G01 baseband, the technology is not mature enough, can not be used on the phone, can only be used on 5G CPE. Subsequently, Mediatek, Samsung and Intel successively released their own 5G baseband chips in 2018 (none of which were commercially available at the time). Let's call these 5G basebands the first generation of 5G basebands.
