The Korean brand ‘Samsung’ introduced a new 5G modem named Exynos 5400 5G modem, which is already available in the Galaxy S24 and Galaxy S24+ and is now expected to arrive in the forthcoming Pixel devices.
The Korean giant built the Exynos 5400, which is its very first modem with built-in NB-IoT NTN and NR NTN network support. It is reported that the Exynos 5400 5G modem will be used in several Pixel devices that will debut later this year, which include:
- The Pixel 9, Pixel 9 Pro, Pixel 9 Pro XL, and Pixel 9 Pro Fold are available.
This feature will permit smartphones and tablets using this modem to have two-way satellite connectivity for messaging. The plus point is that even when there is no cellular network nearby, based on this feature, phones can have the Emergency SOS feature.
This supports both mmWave and sub-6GHz 5G networks and 4×4 MIMO in sub-6GHz and 2×2 MIMO in mmWave 5G networks. This modem seems to be the fastest-ever Exynos modem, which reached download speeds of up to 14.79 Mbps with the help of NR dual-connectivity for FR1 and FR2 bandwidths.
Apart from this, the brand has assured that it is the first-of-its-kind solution that can accumulate five carriers for a total theoretical download speed of up to 11.2 GB/s with 1,024 QAM on just the FR1 frequency band, which is said to be more efficient and reliable than using the FR2 frequency band.
Samsung says that the Exynos 5400 is a power-efficient 5G modem, as it is made using Samsung Foundry’s 4nm EUV process. Whereas the Galaxy S24 and Galaxy S24+ smartphone modems lack NTN connectivity features.
