Samsung’s next wave of Exynos chipsets may be about much more than a new 2nm GAA manufacturing process. According to a new report, the company is exploring an ambitious upgrade: embedding a dedicated neural processing unit directly into the 5G modem. That move would give the baseband chip its own AI smarts to handle real-time satellite communications, potentially transforming how smartphones connect beyond traditional cellular networks.
If this pans out, it could be the next big step for satellite features in phones. Apple set the tone with Emergency SOS via satellite on the iPhone 14, and the wider industry has been working to expand from basic emergency messaging to broader connectivity. Samsung hasn’t yet launched a similar service on its Galaxy devices, but an Exynos platform with an AI-powered modem could open the door to faster, more reliable, and more power-efficient satellite links.
What makes an AI-enabled modem compelling is its potential to solve the hardest problems in direct-to-smartphone satellite communications. Current mobile chipsets struggle to directly interface with massive low-Earth-orbit (LEO) constellations, which can involve communicating with thousands of satellites while constantly switching beams and coping with movement and interference. Integrating an NPU inside the modem could change that in several ways:
– Predict satellite positions and handovers in real time to shorten link acquisition times
– Interpret and communicate beam status more efficiently for stronger, more stable connections
– Dynamically optimize signal strength and power usage, improving reliability while preserving battery life
A recent meeting between a senior executive from Samsung’s semiconductor arm and SpaceX has added fuel to the speculation. Industry watchers suggest Samsung may be aiming to participate in an emerging supply chain for direct-to-device satellite services, with an Exynos SoC tailored for rapid interactions with LEO satellites. The endgame would be smartphones that connect faster and hold onto satellite links more reliably, especially in areas where cellular coverage is patchy or unavailable.
There are still big questions. The report doesn’t confirm whether this AI-in-the-modem approach will debut with the rumored Exynos 2600 or arrive in a later generation. Earlier chatter around the Exynos 2600 pointed to a standalone 5G modem configuration, which can sometimes trade overall efficiency for flexibility. If that’s true, the NPU-enhanced modem may be earmarked for future iterations rather than the first 2nm launch. Either way, pairing a 2nm GAA process with a more intelligent baseband would be a logical route to lower power draw and better thermal behavior—key factors for satellite connectivity that can otherwise strain a phone’s battery and heat budget.
Timing is also in play. Hints suggest Samsung could position the next Exynos platform for devices expected next year, potentially ushering in a broader rollout of satellite features beyond emergency messaging. If the modem-level AI arrives later, Samsung could still lay the groundwork now with architecture and software support that makes future satellite capabilities easier to activate once the hardware is ready.
What this means for users is straightforward: more dependable off-grid communications, faster satellite lock-on, and potentially new services that go beyond SOS—think basic messaging, location sharing, or status updates when cellular networks are down or out of reach. For carriers and satellite operators, an NPU-equipped modem inside millions of phones could streamline how networks manage beam steering, handoffs, and bandwidth allocation at scale.
As with any pre-launch report, it’s wise to temper expectations until specs are official. The current evidence suggests a plausible to probable trajectory: Samsung is clearly investing in AI-centric silicon advances, and the industry momentum behind direct-to-device satellite connectivity makes an AI-enabled modem a sensible next step. Whether it appears first in the Exynos 2600 or follows shortly after, the direction is clear—smarter basebands are coming, and they could redefine how smartphones stay connected when towers disappear from the map.
