Thursday, Oct 2nd, 2025 (9:55 am) - Score 760Mobile operator O2 (Virgin Media) has today announced the deployment of a “first-of-its-kind” mobile Giga Site in Paddington (London), which utilises Nokia’s latest dual-band massive MIMO (Multiple-Input Multiple-Output) tech to boost 5G mobile broadband performance and network capacity. But Massive MIMO dials that up a major notch by enabling mobile operators to harness a greater number of antennas, potentially hundreds. The first mast site in Paddington will also be utilising the 78.8MHz of additional radio spectrum that they recently acquired from Vodafone UK (here), which has already helped to increase O2’s total spectrum holdings to approximately 30% of UK mobile spectrum. The new site is thus capable of bringing together multiple spectrum layers with a mix of low, mid and high-band spectrum. We should add that even if your existing Smartphone doesn’t have the same number of antennas as a Massive MIMO base station, it can still benefit from the increased capacity and more precise signal targeting that such technologies bring.
