Together with the Exynos 990 mobile platform, Samsung is introducing a companion multi-mode 5G modem chip – the Exynos Modem 5123.
Here is EVERYTHING you need to know about the Samsung Exynos Modem 5123, and what it offers over its predecessor, the Exynos Modem 5100!
The Samsung Exynos Modem 5123
The Samsung Exynos Modem 5123 appears to be a companion chip for Exynos 990, which lacks 4G or 5G connectivity. But it could potentially be used to add 5G connectivity to other 4G-only mobile SoCs.
It is one of the first few 5G modem chips built on the 7 nm EUV process, and supports all major wireless standards, from old-school 2G GSM/CDMA to 4G LTE and 5G on both sub-6GHz and mmWave spectrums.
Its 5G capabilities have been significantly improved over the Exynos Modem 5100, with Sub-6GHz speeds of up to 5.1 Gbps and mmWave speeds of up to 7.35 Gbps.
It also received a big boost in 4G LTE bandwidth, using 1024-QAM (Quadrature Amplitude Modulation), which is probably a first in the industry.
