Huawei's 5G chips are the Kirin 990 series, which uses a 7-nanometer process. But Huawei's 5G baseband chip, Balong 5000, uses a more advanced 7nm process, which gives Huawei a technological lead in the 5G field. Huawei is reportedly developing 6 - and 5-nanometer 5G chips, which will further improve chip performance and power efficiency.
