Recently, market research institute released a new research report "Q4 baseband market share tracking in 2019:5G baseband chips capture double-digit revenue share". Revenue in the global cellular baseband processor market fell 3 percent year-on-year to $20.9 billion in 2019, the report said.
The release of the report has once again focused attention on 5G baseband chips. In the 5G technology architecture, baseband chips are used to synthesize baseband signals to be emitted, or to decode received baseband signals. Specifically, when transmitting, the audio signal is compiled into baseband code for transmitting. When receiving, the received baseband code is interpreted as an audio signal. At the same time, I am also responsible for the compilation of address information (mobile phone number, website address), text information (website text, SMS text) and picture information. Baseband chip, as the core support of 5G technology, realizes the whole process of signal from transmitting and compiling to receiving and decoding.
2019 is the first year of 5G's commercial use, and smartphones are seen as one of the first applications of 5G to land. As a core component that affects the performance of 5G mobile phones, the importance of chips is self-evident. Under the circumstance of market demand upgrading, various powerful companies gradually enter the competition of the second generation 5G baseband chips, and the market of 5G baseband chips is particularly lively.
The chips in a mobile phone mainly include memory chips and various processors. Among them, the processor mainly includes RF chip, baseband modem and core application processor. The 5G baseband chip is mainly used to control the network of smart phones, and what is commonly referred to as the strength of mobile signal is the quality of the chip. If there is no baseband chip on the phone, there is no way to communicate with the outside world. With the gradual development of 5G era, baseband has become more and more important and become the key for smart products to connect to 5G network.
