In order to catch up with Huawei, Qualcomm officially announced the new process on 5G. The upgraded version of the Snapdragon X50 5G baseband, the Snapdragon X55, will be commercially available in 2020, and has been adopted by more than 30 OEM manufacturers, including Samsung, Sharp, ZTE, and Wenzhou. Thai Technology, LG, Nokia, OPPO, Panasonic, etc.
It is understood that the Snapdragon X55 uses a 7nm process, and a single chip can support 2G, 3G, 4G, and 5G, of which 5G can fully support millimeter wave and frequency bands below 6GHz, TDD time division duplex / FDD frequency division duplex two modes , and the dual networking mode of SA independent networking and NSA non-independent networking.
It is worth mentioning that in both FDD/TDD modes, the Snapdragon X55 not only complements the FDD frequency band below 6GHz, but also fully supports 800MHz and lower frequency bands. At the same time, the performance of the baseband in 4G has also been improved, not only the support system has been upgraded to LTE Cat. 22. It can also support seven carrier aggregation and 24 data streams at the same time, as well as FD-MIMO (full dimension) technology.
In order to reduce the workload of mobile phone manufacturers, Qualcomm also said that the Snapdragon X55 has a complete 5G radio frequency solution, which integrates radio frequency transceivers, front-end devices and antenna arrays into a QTM525 millimeter wave module to control the thickness of the entire mobile phone. Within 8mm, that is to make 5G mobile phones have the same thin and light appearance as 4G mobile phones.
However, Qualcomm still has not solved the problem of baseband plug-in, which is indeed lagging behind Huawei Kirin 990 in this regard. This also makes relevant industry insiders believe that Qualcomm is at least half a year behind Huawei in 5G competition.
