Samsung announced its name earlier.Exynos modem 5410The new 5G data chip, manufactured using a 4nm process, is now in mass production and is expected to become a standard feature of next year's flagship Galaxy S26 series. Its biggest highlight is the fully upgraded "satellite communication" capability, which can even make video calls directly via satellite.
Satellite communications are no longer just for "lifesaving" purposes; they encompass three major technologies.
Current satellite communication capabilities are mostly limited to sending emergency SOS text messages, but the Exynos 5410 clearly aims to do more. Samsung states that this chip supports all three major satellite communication technologies:
• NB-IoT NTN (Internet of Things Non-Terrestrial Network):This is the basic model, designed for location sharing and simple text transmission in remote areas (similar to existing emergency SOS systems).
• LTE DTC (Direct-to-Cell):Further expand capabilities to allow mobile phones to make voice calls directly via satellite.
• NR-NTN (5G non-terrestrial network):This allows ordinary mobile phones to connect to 5G satellite networks, with bandwidth large enough to support video calls and large file transfers.
This means that in the future, if you take your Galaxy S26 to a remote mountain area, you can not only send your coordinates for help, but you may even be able to broadcast the scenery to your friends via satellite signal bandwidth.
Download speeds soared to 14.79Gbps, with security protection against "quantum" attacks.
In terms of network speed, the Exynos 5410 boasts impressive data throughput. By supporting 5G NR dual connectivity and utilizing both FR1 (Sub-6GHz) and FR2 (millimeter wave) bands, it achieves a maximum download speed of 14.79Gbps. Even using the FR1 band alone, it can achieve a transmission speed of 11.2Gbps through 380MHz bandwidth aggregation.
In addition, to address future cybersecurity threats, this chip incorporates ROM-based hybrid post-quantum cryptography (PQC) technology and is equipped with a dedicated security chip to encrypt sensitive data such as IMEI numbers, preventing future quantum computers from cracking traditional encryption mechanisms.
Does the Exynos 2600 use an "external" data chip design?
It is worth noting that Samsung recently announced...Exynos 2600 processorThe design does not integrate a 5G data chip. Therefore, the Galaxy S26 is expected to use an "external" form factor, connecting to the mobile network via the Exynos 5410 data chip.
This approach was common in early 5G phones (such as the iPhone 12/Snapdragon 865 era). The advantage is that the data chip can be made more powerful and has more independent operation advantages, but the disadvantage is that it often occupies more motherboard space, and its power consumption and heat management face greater challenges than integrated chips (SoC).
Analysis: Satellite communications have entered the "broadband" era.
The launch of the Exynos 5410 symbolizes the transition of mobile satellite communication from a "narrowband" era limited to text transmission to a "broadband" era capable of transmitting images. While Apple and other competitors are still emphasizing emergency SOS applications, Samsung is attempting to make satellite connectivity a regular means of communication.
However, what gamers are most worried about is probably the "external" design. In the past, the energy efficiency of Exynos processors has always been a sore point for Samsung. If the Galaxy S26 really adopts an external design, whether the Exynos 5410 can successfully control power consumption while providing high-speed satellite connectivity will be a key test for the Galaxy S26 to regain its former glory.
