T-Mobile US unveiled a large-scale deployment of low latency, low loss and scalable (L4S) technology across its network, which it claimed is an industry first.
John Saw, EVP and CTO for the mobile operator, stated in a blog post L4S is key for reducing lag, jitter and network congestion to enable services such as cloud gaming, video calling, XR devices and remote driving.
“Because everything flows through a single, optimised 5G core, we can deploy programmable features like L4S at scale while laying the groundwork for advanced network slicing and differentiated service tiers,” Saw stated.
It uses T-Mobile’s standalone (SA) 5G core and nationwide 5G-Advanced network to enable high-performance applications across various real-world scenarios.
The mobile operator got a jump on rivals AT&T and Verizon by rolling out its SA 5G network across the US in 2020, which also gave it an early lead for 5G-Advanced features.
T-Mobile announced the nationwide launch of its 5G-Advanced network in April.
A representative for T-Mobile told Mobile World Live L4S is deployed on part of its 5G-Advanced network with a plan to expand coverage over the coming weeks.
“In fact, many cities already have L4S-enhanced 5G-Advanced available, and our team is working hard to make it nationwide very soon.”
Rival Verizon teamed with Ericsson to trial L4S technology last year.
In late January, US cable operator Comcast announced a L4S-based trial across six cities which featured lower latency for its broadband subscribers.
