Why you can trust our reporting
We have reported on Charter Communications and their Spectrum service offerings for years; our more-recent coverage includes a story on Charter’s first quarter (Q1) financial earnings focused largely on its broadband offerings and a report on the FCC’s approval of Charter’s combination with Cox Communications, which is largely predicated on expanding and supporting broadband services. For this story, we relied on information supplied by a Charter spokesperson, coupled with our prior reporting on the company.
Charter Communications has started rolling out ultra low-latency Internet service on its Spectrum broadband network, a move that the company says will make online gaming, video calls, artificial intelligence tools and other real-time applications more responsive for customers.
The new capability is powered by L4S, short for “low latency, low loss, scalable throughput,” a networking technology designed to reduce delays in the transfer of data between a user’s device and an online service. Spectrum said the feature is automatically included with Spectrum Internet service at no additional cost.
The technology is currently available to Spectrum customers in the Dallas-Fort Worth area of Texas; Reno, Nevada; Rochester, Minnesota and St. Louis, Missouri. Charter said it will expand the capability to more markets as it continues a broader network evolution project across its service footprint.
“Speed gets you there, but latency determines how it feels once you arrive,” Danny Bowman, the Executive Vice President of Product at Charter, said in a statement. “Many of today’s most popular applications require real-time responsiveness. This is about eliminating delays so customers can enjoy gaming, working or connecting with family via video in a way that feels immediate.”
Latency refers to the time it takes for data to travel between a user and an online service. While broadband providers have historically marketed Internet service around download and upload speeds, latency has become a more important performance metric as households rely on applications that require near-instant responses.
In gaming, lower latency can reduce the delay between a player pressing a button and seeing the action occur on screen. In video conferencing, it can help minimize overlapping conversations and pauses. Charter said the technology can also support AI applications and other services where real-time responsiveness is important.
The company said its low-latency network is designed to work with products from companies including Nvidia and other developers that build applications to meet L4S standards. When both the network and the application are optimized for L4S, Spectrum said customers should experience smoother and more responsive connections.
The rollout comes as cable operators invest in network upgrades intended to keep their broadband platforms competitive against fiber providers and fixed wireless services. Charter has been working on a multi-year network upgrade initiative that includes improvements to capacity, speed and overall performance across its footprint.
By adding L4S-based ultra low-latency service without a separate fee, Spectrum is positioning the upgrade as part of its standard broadband offering rather than a premium add-on. The company did not provide a specific timeline for when the technology will reach additional markets.
As of March, Charter reported more than 29.6 million broadband Internet relationships, comprising a sizable chunk of its 31 million customer connections.
