The brand new Tokyo trial diminished wi-fi hyperlink latency by round 90% in contrast with situations that didn’t use 5G and 5G Superior applied sciences corresponding to L4S
In sum – what to know:
Latency discount – The trial confirmed 90% wi-fi latency enhancements by combining L4S and different 5G Superior options on a reside 5G SA community.
Actual-world XR – Sensible-glasses XR streaming was used to validate low-latency efficiency in a demanding, real-time software.
Community slicing – Superior 5G capabilities have been remoted to check units, exhibiting how operators can tailor networks for particular providers.
Japanese service SoftBank, Ericsson Japan, and Qualcomm Applied sciences have accomplished a subject trial testing low-latency 5G and 5G Superior options on SoftBank’s business 5G Standalone (5G SA) community in Tokyo.
The trial targeted on applied sciences designed to cut back delay and enhance stability, together with low latency, low loss, and scalable throughput (L4S), together with different 3GPP-standardized options corresponding to configured uplink grant and rate-controlled scheduling.
As a real-world use case, the businesses examined XR content material streaming on good glasses. The glasses related to a smartphone by way of Wi-Fi, whereas the smartphone accessed the 5G SA community by devoted base stations. Information was exchanged with software servers over the general public web.
XR purposes are extremely delicate to delay, as even small latency points can have an effect on visible high quality and person expertise. In accordance with the businesses, the trial diminished wi-fi hyperlink latency by round 90% in contrast with situations that didn’t use 5G and 5G Superior applied sciences corresponding to L4S. The system delivered steady, secure low-latency efficiency, the businesses mentioned.
The trial additionally used community slicing to restrict superior 5G options to the check units, permitting the community to be optimized particularly for XR site visitors with out affecting different customers.
SoftBank led web site choice and efficiency analysis, Ericsson provided and configured 5G and 5G Superior options, whereas Qualcomm Applied sciences supplied the good glasses, smartphone, and XR software used within the trial.
Jawad Mansour, president and consultant director at Ericsson Japan, added: “This subject trial is a crucial initiative that demonstrates ultra-low-latency, high-reliability communication required for next-generation XR experiences. XR has the potential to rework how work is completed throughout many fields — business, social infrastructure, leisure, and extra.”
In the meantime, Hemanth Sampath, VP engineering at Qualcomm Applied sciences, famous that this initiative highlights the potential of mixing XR and 5G applied sciences and showcases the worth of distributed spatial computing and low-latency on-device capabilities enabled by the Snapdragon XR platforms.
In August 2025, Ericsson mentioned it had expanded its relationship with SoftBank by a brand new business settlement targeted on 4G and 5G radio community options. Underneath the phrases of the deal, Ericsson will provide radio entry gear to help SoftBank’s community enhancements throughout a number of key areas throughout Japan.
The settlement covers a variety of spectrum bands — low, mid, and excessive — and consists of enhancements to the service’s 4G community in addition to an expanded rollout of 5G Standalone (5G SA).
