T-Mobile US unveiled an AI-enhanced network optimisation capability aimed at keeping customers connected during high-density events including at packed stadiums, festival grounds and in post-concert taxi queues.

The mobile operator’s Dynamic CX is built on its self-organising network (SON) platform, which is also used to allocate network resources during natural disasters.

Operators have been using centralised self-organising network (C-SON) tools since 2010. In 2015, machine learning algorithms were introduced and blended with SON algorithms, which led to the first iteration of AI-for-RAN.

It is another feature built on the operator’s nationwide 5G-Advanced network which sits on its standalone 5G architecture.

Dynamic CX’s AI-driven automation adapts to network conditions in near real time, marking a meaningful step beyond traditional SON optimisation, which has historically been more reactive in nature.

The AI-enabled network optimisation capability continuously monitors and tunes network performance.

Dynamic CX scans publicly available event information, schedules and online activity to identify upcoming mass gatherings before they happen, allowing the network to begin preparing capacity adjustments in advance rather than scrambling to react once congestion hits.

Once an event is underway, Dynamic CX shifts into continuous monitoring mode, tracking how demand evolves as crowds move, stream and share throughout venues and surrounding areas.

T-Mobile is positioning the launch ahead of the FIFA World Cup, which starts this month and uses 11 US host cities. It is expected to draw millions of international visitors over several weeks.

CTO John Saw framed Dynamic CX as part of a longer arc of event-readiness investment to improve customer experience.

T-Mobile pointed to broader World Cup operational preparations including coordination with public safety agencies, staged deployable network assets and heightened cybersecurity posture across event-related infrastructure.

MediaTek and Samsung completed what they claimed was the first successful test of a 3Tx five-layer uplink configuration, achieving a total uplink throughput of 670 Mb/s in a joint demonstration.

The test combined MediaTek’s M90 5G modem platform with Samsung’s virtualised RAN (vRAN), Massive-MIMO radios, and Macro radios to set “a new standard in 5G uplink performance”.

The trial integrated three transmit antennas (3Tx) across five uplink layers, using a multi-band setup which combined n66 (1.7GHz) as the primary cell and dual n77 (3.7GHz) carriers.

The configuration represents an extension of earlier three transmit antenna work by using five uplink layers to push spectral efficiency and peak upload speeds beyond previously demonstrated benchmarks.

Samsung’s vRAN provided the network backbone for the trial, with the virtualised architecture allowing flexible resource allocation across multiple frequency bands while serving multiple users simultaneously. Massive-MIMO radios handled advanced antenna processing to manage the parallel data streams with reduced interference.

HC Hwang, GM of wireless communication systems and partnerships at MediaTek, stated the validation marks a significant step for the company’s 5G platform as demand for high-resolution cloud applications continues to grow.

Dongwoo Lee, head of technology solution Group at Samsung Networks, stated the results demonstrate speeds capable of meaningfully improving user experience across both consumer and enterprise applications.

The companies explained the achievement strengthens fixed wireless access performance with improved uplink peak speeds.

The companies did not announce a timeline for commercial deployment.
