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.
