Samsung shows the Exynos 5100 5G modem at the IFA 2018. It is a multimode modem and thus backward compatible with the previous GSM, UMTS, and LTE mobile radio standards. So far, there were only single-mode 5G modems, for earlier wireless standards, an additional modem was necessary.
Samsung Exynos 5100 modem Speeds
The Samsung Exynos 5100 5G NR (New Radio) modem is fully compatible with the recently adopted 5G NR standard (3GPP Rel. 15). The Samsung 5G modem supports both the frequency range below 6 GHz and the millimeter-wave range. Below 6 GHz, speeds of up to 2 GBit/s are achieved with a suitably equipped mobile network; in the mmWave range, speeds of up to 6 GBit/s are possible. If no 5G, but if only LTE is used, according to Samsung, at least up to 1.6 gigabits per second in the downlink are possible.
As already mentioned in the introduction, the Samsung Exynos 5100 is a multimode 5G modem, so in addition to 5G NR, LTE, WCDMA (UMTS), CDMA, TD-SCDMA, and GSM are also supported.
In the frequency range below 6 GHz, a total of up to 100 MHz frequency spectrum can be used simultaneously (eg via carrier aggregation), and 256QAM modulation is also supported in the downlink. In the antenna technology, the modem is limited to 4 × 4 MIMO below 6 GHz; in the mmWave range, hybrid beam forming antenna technology is possible.
Samsung Exynos 5100 featured only modem, no SoC
The Exynos 5100 is a pure modem, if used in a smartphone, the combination with a processor and other components are necessary. Today, however, smartphones often use a system-on-a-chip (SoC), a single chipset that combines all the important components, such as processor and modem. For example, the Exynos 5100 could also be used in a 5G router without SoC. When the first products with the Exynos 5100 Multimode 5G modem will be launched on the market, was not to be discovered at the IFA 2018.
