The launch of the Galaxy S9 at the end of February will usher in the one Gbps era for the first time as an LTE smartphone. This will become possible thanks to the combination of a more powerful application processor (AP) chipset and advanced mobile carriers' frequency utilization technology.
According to the mobile telecommunication service and hardware manufacturing industries, in theory, the Galaxy S9 can realize a telecommunication speed of up to one Gbps. At this speed, you can download a 1GB movie or receive 250 4MB MP3 songs in eight seconds. On paper, the Galaxy S8’s maximum speed is about 900 Mbps. The Galaxy S9 is 10% faster than the Galaxy 8 in terms of processing speed.
The Galaxy S9 has been made faster by its chipset and mobile carriers’ frequency utilization technology that can make the most of the chipset. First of all, the Galaxy S9 has stronger career aggregation (CA) than the previous version. CA technology combines different and separate frequencies into one frequency. Although the Galaxy S8 loaded with the Exynos 8895 can realize up to 5 CAs, the Galaxy S9 to be released this year will be loaded with the Exynos 9180 which can realize 6 CAs. Definitely, there is an overt difference in speed in reason.
At present, however, 6-CA technology has not been standardized yet, and there is no mobile carrier in the world that can support the technology now. It is said that even SK Telecom with the largest number of LTE frequencies in Korea put an end to LTE technology through 5 CAs. This means that as the statue of frequencies in Korea has not changed since the time the Galaxy S8 was launched, it is quite a big challenge to accelerate the speed of the Galaxy 9.
Under these circumstances, the use of 4x4 multiple input/multiple output (MIMO) technology elevates the Galaxy S9’s telecommunication speed. This technology ramped up the number of terminal and base station antennas to four in a specific frequency band. Mobile carriers raised speed as high as they could by applying MIMO technology to a space with room to spare as CAs that can support the Galaxy S9.
"Wireless telecommunication has become able to offer gigabyte-class speed," said an official in the Korean telecommunication industry. “This means that traffic dispersion effects not only for the Galaxy S9 users but for users of other smartphones will enable all users to avoid telecom traffic congestions while enjoying network optimization effects.
