Vodafone trials lower-power 5G mode that restores capacity in seconds
Vodafone is testing radio power-saving techniques in Türkiye that can cut energy use while keeping mobile service available and restoring full 5G capacity within seconds.
Vodafone is testing a new way to reduce the energy consumed by 5G radio equipment without making customers wait for connectivity to return when demand rises. The trial, announced on July 8, is taking place in Türkiye and combines software, hardware and next-generation radio techniques at Vodafone’s multi-vendor test facility in Istanbul.
The company says the approach achieved up to 10% energy savings through software- and hardware-based power management, with an additional 20% reduction when next-generation radios were used. Vodafone presents the work as an industry-first test aimed at making mobile networks more efficient while preserving the capacity needed in busy areas.
Radio capacity follows demand
Mobile networks do not carry the same amount of traffic at every moment. A busy urban area can require a large amount of radio capacity during a commute, a public event or a sudden change in local demand, while the same equipment may be lightly used at other times. Vodafone’s trial is designed to let parts of the radio system reduce their power consumption during quieter periods and reactivate when more capacity is needed.
In its maximum energy-saving mode, the radio antenna can operate using as little as 10 watts, which Vodafone compares with the power used by a standard LED light bulb. The company says the equipment can return to full capacity in approximately 30 seconds. During that transition, service continues over low- and mid-band frequencies, while full capacity is restored by reactivating Massive MIMO radios using the 3.5GHz spectrum.
Vodafone is also testing a faster response mode. In that configuration, the radios operate at 50 watts and can return to full performance in less than five seconds. That shorter recovery time is intended for situations where traffic can increase quickly and additional capacity must be made available almost immediately.
Why the test matters for network resilience
The trial is not presented as a setting that smartphone owners can activate themselves. It is a network-side system being evaluated by Vodafone engineers. If the approach can be refined for wider deployment, the potential benefit is that operators could reduce unnecessary power use while keeping the network ready for changes in demand.
Vodafone also links the work to resilience during electricity-grid outages. Mobile base stations rely on backup power when the grid is unavailable, so lowering the energy draw of radio equipment can help those supplies last longer. The company says the technology is intended to support uninterrupted mobile service while improving the operating time available from backup systems.
That distinction is important. Vodafone has announced a trial and ongoing testing, not a timetable for a customer-facing rollout. The results described by the company come from a controlled test environment, so they do not establish how the system would perform across every commercial network, device combination or traffic pattern.
Testing at Vodafone’s Istanbul facility
The work is being carried out at BESTT, short for Benchmark Environment Site Testing in Türkiye. Vodafone describes the Istanbul centre as a multi-vendor mobile test and innovation facility that replicates a live network. It is used to validate radio access network software and hardware and to support work on 5G Advanced applications.
A multi-vendor environment is relevant because mobile networks combine equipment and software from different suppliers. Power-saving behaviour therefore has to work across the radio system rather than being treated as an isolated smartphone feature. Vodafone says it will continue testing and refining the technology with advanced algorithms intended to maintain a fast and reliable 5G connection.
The announcement follows Vodafone Türkiye’s commercial 5G launch in April 2026, when the operator said the network was activated across all 81 provincial centres. The new trial does not change that coverage announcement; it focuses on how the network’s radio equipment can use power more efficiently once the infrastructure is operating.
A practical step toward more efficient 5G
Energy efficiency has become a network-performance issue as well as a sustainability concern. Operators need enough capacity for growing data use, but they also need to manage the electricity required by dense radio infrastructure. Vodafone’s test explores a middle ground: reduce power during quieter moments, preserve service through lower- and mid-band layers, and bring higher-capacity radios back online when demand requires them.
The most useful result will be whether those transitions remain predictable under real traffic conditions. Vodafone’s two operating modes suggest different priorities: the 10-watt mode targets maximum savings with a recovery time of about 30 seconds, while the 50-watt mode keeps more power available for a return to full performance in under five seconds. Further testing will determine how those trade-offs work outside the laboratory environment.
For now, the announcement points to a network-level evolution rather than a new phone feature. Vodafone is trying to make 5G infrastructure more adaptive, using power only when capacity is needed while keeping a rapid path back to full performance. That could help operators balance connectivity, operating costs and resilience as mobile networks continue to expand.
