VodafoneThree deploys Ericsson AIR 3266 across London 5G

By Amara Osei

Ericsson's AIR 3266 is being deployed across VodafoneThree's London 5G network in a SEK 12.5 billion partnership covering RAN solutions at more than 10,000 sites and core-network solutions nationwide. The London rollout forms one part of that national programme.

The announcement gives no London site count, subscriber total or measured throughput for the new radio. Its scale, for now, remains less precise than the headline.

Iain Milligan, Network Development and Infrastructure Director at VodafoneThree, said: “This deployment of Ericsson's AIR 3266 is another important step in our £11 billion investment to build the UK's best network.” He says it will expand the UK's 5G SA footprint, increase capacity and coverage, reduce energy consumption and simplify deployment, though measured network-wide results still have to arrive.

What does AIR 3266 bring to the radio network?

Each AIR 3266 radio combines 5G mid-band TDD Massive MIMO with support for up to 400 MHz of bandwidth. Ericsson says that pairing improves spectral efficiency and performance, letting VodafoneThree use more mid-band spectrum to increase 5G capacity and coverage as deployment scales.

The radio weighs 16 kg, and Ericsson says its ultra-slim design reduces physical wind load while simplifying deployment and installation. Those constraints matter as data demand grows and operators add equipment to sites they cannot redesign; the hardware has to earn its keep twice.

What does the AI claim actually mean?

Next-generation Ericsson Silicon inside AIR 3266 includes dedicated neural accelerators that boost AI-inference capabilities tenfold, according to Ericsson. The company says AI models can optimize time-sensitive radio functions in real time, keeping performance consistent as traffic patterns change.

Combined with AI-ready RAN compute already deployed in VodafoneThree's network, the silicon provides a foundation for adding new AI software capabilities. That is the vendor's architectural argument; the commercial test is what the software delivers once live traffic exercises it.

Will the scheduler improve throughput?

Initial testing of Ericsson's AI-native Scheduler for Link Adaptation has demonstrated up to 20% higher downlink throughput in congested conditions, according to the announcement. The company provides no subscriber count or citywide throughput measurement to show whether that test result carries across the London deployment.

VodafoneThree will trial the scheduler before the end of its financial year. Subject to successful validation, it plans a nationwide rollout in 2027, giving the software's national arrival a date but not yet a guarantee.

What do the energy and carbon claims mean?

Ericsson says AIR 3266 delivers energy savings of 30% or more and up to 50% lower embodied carbon than solutions currently deployed by VodafoneThree. The announcement offers no independent energy or lifecycle-carbon assessment, leaving those figures as product performance claims rather than demonstrated results across the operator's estate.

The combination of processing power, compact design and energy efficiency is intended to support VodafoneThree's sustainability objectives as it expands 5G SA across the country. Simpler installation also reduces the physical work of adding radio capacity, which matters when new sites arrive with their own spatial and environmental limits.

What does the partnership have to deliver?

VodafoneThree and Ericsson say the partnership will improve connectivity for consumers and enterprises and provide a platform for new mobile experiences, industrial applications and AI services. Coverage expansion across the UK remains the shared objective, with the London deployment presented as the latest milestone rather than the finish line.

The SEK 12.5 billion partnership sits alongside VodafoneThree's £11 billion network investment, rather than replacing it. One covers the radio and core technology; the other funds the wider build. The distinction matters, because an investment headline is not a measured network result.

What does the world-first claim mean?\n

Luca Orsini, Head of Ericsson North Europe, said: “Being first in the world to deploy Ericsson's AIR 3266 is a clear signal of the pace and ambition behind our partnership with VodafoneThree.” He also said the upgrade would improve customer experience and coverage in “one of the UK's busiest networks”, while reducing energy use and carbon footprint.

The announcement provides no subscriber total to test the “busiest” description. For now, the world-first claim applies to the equipment deployment, while the broader AI benefits remain tied to trials and planned software releases.

What happens next?

The next checkpoint is the scheduler trial before VodafoneThree's financial year ends. If validation succeeds, the company plans nationwide rollout in 2027, while the London radio deployment and wider £11 billion network investment continue.

The hardware claims and software results will face the same scrutiny: evidence from the deployed network, not just launch-day specifications. The planned sequence is trial, validation and, if both go well, a 2027 nationwide rollout.
