Tesla and Samsung: 5G Modems for Robotaxis Starting in 2026

Tesla has just reached a new milestone in its quest for technological independence. The Californian manufacturer has partnered with Samsung Electronics to develop a 5G modem specifically designed for its autonomous vehicles.

The project started in early 2024, and the first modules are expected to equip the Robotaxi fleet in Texas starting in the first half of 2026. But this partnership goes far beyond a simple connectivity issue: it is part of a global strategy that also includes AI6 chips, essential for the operation of the autonomous driving system.

In my view, this dual agreement marks a major turning point. Tesla regains full control of its technological supply chain, reduces its reliance on third-party suppliers like Qualcomm, and positions itself as a truly integrated player in autonomous mobility.

Let’s break down the stakes of this strategic alliance.

Samsung Develops a Custom 5G Modem for Robotaxis

Starting in early 2024, Samsung Electronics launched the development of an automotive 5G modem meeting the industry’s drastic requirements.

Unlike smartphone modems, designed for 2 to 3-year lifecycles, these components must withstand extreme conditions: temperatures ranging from -40°C to +85°C, constant vibrations, and a minimum lifespan of 10 years. These strict automotive specifications impose reliability constraints far superior to consumer electronics.

Currently in the test phase, the modules are expected to be delivered in the first half of 2026. Samsung manages the entire design, while a third-party partner handles the final integration into the vehicles.

But why is 5G so crucial for autonomous cars? Three main reasons:

• Ultra-low latency: essential for real-time decisions
• High throughput: enables rapid transfer of massive data (mapping, video, telemetry)
• Reliability: ensures a stable connection even in dense areas

The first deployment will concern the Texas Robotaxis, which will serve as a full-scale test ground. If the results are conclusive, Tesla will gradually extend this technology to its consumer range.

A Partnership Deepening Far Beyond Connectivity

AI6 Chips: The 22.7 Trillion Won Contract

The 5G modem is just the tip of the iceberg. In mid-2025, Tesla signed a colossal contract with Samsung for 22.7 trillion South Korean won, or approximately 15.3 billion euros.

The object? The supply of AI6 chips, which power the autonomous driving system and the onboard computing infrastructure required for advanced Full Self-Driving features.

Samsung thus becomes a strategic pillar of Tesla’s supply chain. This dual partnership – AI chips + 5G modems – allows Tesla to exercise total control over the connected hardware stack of its autonomous vehicles.

In my view, it’s proof that Tesla aims for absolute mastery of every critical component, rather than relying on third-party ecosystems.

Tesla Diversifies Its Suppliers and Reduces Its Reliance

Previously, Qualcomm was the historical modem supplier for Tesla. But Elon Musk has always prioritized technological independence.

By now relying on Samsung, Tesla reduces its exposure to geopolitical tensions, particularly those between China and Taiwan, which directly impact the semiconductor industry.

Samsung, based in South Korea, represents a geopolitically more neutral partner. This diversification secures the supply chain against global uncertainties.

Tesla applies the same strategy here as for its batteries: never to depend on a single player. This principle is found with Chinese LFP cells on one side, and internally produced 4680 batteries on the other.

Why 5G is Critical for Full Self-Driving

Autonomous driving relies on permanent and ultra-reliable connectivity. Without it, it’s impossible to efficiently operate a Robotaxi fleet.

Here are the critical uses of 5G for Tesla:

• Real-time mapping: instant update of traffic conditions, obstacles, roadworks
• Centralized fleet management: Robotaxi coordination, route optimization, intelligent dispatching
• Over-The-Air software updates: continuous deployment of fixes and improvements, even for multi-gigabyte files
• V2X Communication (Vehicle-to-Everything): data exchange with road infrastructure and other vehicles

The ultra-low latency of 5G also ensures increased responsiveness in emergency situations. Every millisecond counts when an autonomous vehicle needs to make a critical decision.

By controlling both the hardware and software stack, Tesla gives itself a decisive competitive advantage against Waymo, Cruise, and other autonomous mobility players.

Texas 2026: The Full-Scale Test Ground

The initial deployment of 5G modems is planned for the Robotaxi fleet in Texas starting in the first half of 2026.

Why Texas? Several strategic reasons:

• Favorable regulatory framework for autonomous vehicle experimentation
• Existing Tesla infrastructure, especially with the Austin Gigafactory
• Varied conditions: dense urban traffic, fast highways, changing weather

This test phase in real-world conditions will allow for the collection of massive data to continuously improve Full Self-Driving algorithms.

If the results are successful, Tesla will quickly extend the deployment to other states, then to consumer vehicles. The timeline is perfectly aligned with the commercial launch ambitions of Robotaxis.

Samsung will deliver the modems just in time for this crucial stage, demonstrating the strength of this strategic collaboration.

What This Concretely Changes for Tesla Owners

In the short term, starting in 2026-2027, new Tesla models will benefit from significantly improved onboard connectivity.

Specifically, you’ll enjoy:

• Smoother navigation with real-time updated maps
• Video and music streaming in high quality, without latency
• Online gaming without lag, directly from the central screen
• Faster OTA updates, even for large updates

In the medium term, Full Self-Driving features will be enhanced thanks to 5G bandwidth. New services will become possible, such as real-time Sentry Mode monitoring, or instant remote diagnostics in case of a technical issue.

For future Robotaxi users, the user experience will be optimized: instant booking, real-time tracking, more responsive service.

This Samsung-Tesla partnership represents much more than a simple technical evolution. It lays the foundations for a fully controlled ecosystem where every component – from the 5G modem to artificial intelligence chips – is optimized for autonomous driving. According to industry analysts, this vertical integration could definitively propel Tesla to the forefront of the autonomous mobility race.
