Spectrum Rolls Out New Ultra-Low Latency Internet

Spectrum recently launched ultra-low latency internet powered by L4S technology to improve everyday online experiences. Say goodbye to video call freezing, video game lagging, and buffering while streaming with Spectrum’s enhanced internet service. Spectrum’s new ultra-low latency internet is automatically included with all internet plans at no extra cost—but is currently limited to select areas.

Spectrum’s new and improved low-latency internet is currently only available in select parts of Minnesota, Missouri, Nevada, and Texas—but will continue to expand across the nation. Spectrum customers will continue to see less latency in applications and services that support L4S, making it a more competitive player on the market.

But how much does Spectrum Internet cost to new customers? Let’s dive into Spectrum’s current internet plan offerings.

Ultra-low latency for Spectrum customers

Spectrum rolled out ultra-low latency internet for customers in select areas across four states so far, but it is continuing to expand this technology to more customers. If you live in Minnesota, Missouri, Nevada, or Texas, you’ll want to check if the ultra-low latency tech is available in your area. Spectrum’s continual network evolution aims to bring L4S technology to customers across the nation. Let’s take a look at the internet plan speeds and prices that Spectrum offers.

Spectrum offers a variety of speeds so customers can choose a plan that fits their household’s needs. But Spectrum’s support for L4S technology goes beyond speed and aims to reduce, if not eliminate, latency across all its plans.

Low-latency leads to seamless connectivity

L4S technology controls internet congestion before it happens with early Explicit Congestion Notification (ECN) markers. These markers send warnings at the earliest signs of data congestion queues building up to prevent congestion levels from getting high enough to cause noticeable delays during gaming, streaming, or other bandwidth-heavy online activities. Network queues and congestion fluctuate, but L4S technology helps ensure internet users don’t experience lag and maintain smooth network performance. Once these network improvements come to your area, you’ll want to verify your devices and applications support the new technology—especially if you have older devices or haven’t updated your apps in a while.

Get ready to experience ultra-low latency internet as a Spectrum customer and start enjoying seamless connectivity.

FAQ about L4S technology

What is L4S?

L4S is an acronym for Low Latency, Low Loss, Scalable Throughput. It is a set of standards developed by the Internet Engineering Task Force (IETF) to reduce the harmful effects of network congestion. It combines scalable congestion control algorithms with Explicit Congestion Notification (ECN) and Active Queue Management (AQM) to signal congestion before packet loss occurs. This allows endpoints to adjust transmission rates and keep network queues short, reducing latency, jitter, packet loss, video stuttering, and gameplay lag.

What is packet loss?

Units of data, called packets, are transferred from one point to another across a network, whether it’s local, regional, or global. Packet loss occurs when the data does not reach its destination due to network congestion. The result is choppy video, slow game downloads, and so on.

What applications and platforms support L4S?

Here are a handful of examples that now support L4S technology:

• Apple FaceTime
• Apple iOS 17
• Apple iPadOS 17
• Apple MacOS
• Apple QUIC and TCP networking stacks
• Apple Vision Pro
• CableLabs DOCSIS 3.1 and newer
• Meta Quest
• NVIDIA CloudXR
• NVIDIA HeForce NOW
• Steam (Valve)

Do other internet providers support L4S technology?

Xfinity is the only other internet provider that has publicly announced the use of L4S technology. The company said back in June 2025 that it teamed up with Apple, NVIDIA, Meta, and Valve to reduce latency for Xfinity customers.
