The SoC Is Separated From The 5G Modem, Why?(3)

- Dec 19, 2018 -

It is difficult to meet the needs of Netcom


In addition, from the baseband strategy built into the back cover of Moto Z3, it is easy to see that the single X50 5G modem can't solve the multi-mode problem. It must cooperate with X24 to complete the support for 3G and 4G networks. If the terminal only supports the 5G network, it will be difficult to meet the user's Internet access requirements under the existing coverage conditions. At present, only Samsung's Exynos 5100 can achieve full support for 2G/3G/4G/5G, X50 and Baron 5G01 only support 4G/5G dual mode.


However, according to Forrester's previous estimates, corporate customers and consumers will see 50% global coverage by 2025. At present, the industry generally believes that 4G and 5G will coexist for a long time in the future, using 5G in cities, and 4G coverage in rural areas. The coverage speed of 5G will be much slower than 3G and 4G, and the coverage may take 5-10 years. In other words, if a product that can be aimed at consumers is introduced, the terminal must support the existing 2G/3G/4G/5G network. Under the existing technical conditions, only the baseband already built in the SoC is available. With the external 5G baseband, the product can meet the access needs of all consumers.


Therefore, this year's flagship SoC chip also has a built-in 4G baseband with ultra-high network performance. For example, the X24 is built in the Snapdragon 855, the Baron 765 is built in the Kirin 980, and the Cat 20 is also supported in the Exynos 9820. Both have improved from the previous generation. Such Qualcomm, Samsung OEMs can also have more product flexibility, after all, next year's trial commercial phase, 5G is not just the consumer's just need.
