The new generation of mobile networks, i.e. 5G, is fast approaching. Producers of base stations have presented the possibilities of new technology more than once. In turn, manufacturers of integrated circuits are working on 5G modems, which in the near future will be found in smartphones. Samsung at the CES 2018 has presented its Exynos 5G modem. Unfortunately, the demonstration took place behind closed doors and no photos or recordings were published. Fortunately, we got to know a few details about the technical solutions.

During the previous 5G tests, test platforms were used in which the 5G user equipment device is the size of a small refrigerator. These are actually SDR (Software Defined Radio) systems that allow manufacturers to test the implementation of developed algorithms. Later, these solutions are transferred to SoC chipsets (System on a Chip). Qualcomm already praised the working Snapdragon X50 5G modem. Intel, at the end of last year, announced the creation of the XMM 8060 modem. Samsung joins this group, but promises to catch up with its competitors.

The Exynos 5G modem will appear on smartphones in 2019

All producers announce that they will make it and at the turn of 2019/2020 we will be able to use the first 5G networks. Samsung’s modem will be compliant with the 3GPP 5G Release 15 standard, which is expected to be finalized in the middle of this year. The modem will support frequencies with bands below 6 GHz, as well as 28 GHz and 39 GHz millimeter bands. The same chipset, in addition to 5G, will also support older technologies, i.e. 2G GSM, 3G and 4G LTE. However, the maximum data transfer speed of 5 Gbps will be achieved in the millimeter band, where it is possible to aggregate 8 radio channels with 100 MHz bandwidth each. Both of the 5G NR network modes defined by 3GPP will also be supported. This is the dual connectivity mode, which assumes the interoperability of the 5G and LTE networks, and the standalone mode, where the 5G base station transmits both user data and signalling streams. Samsung also announced that in the second half of 2021 or in 2022 will prepare smartphones compatible with 5G Release 16, which is referred to as the complete standard of the new generation of cellular networks.
