Telecoms pour $83% more into 5g sa cores as 6g looms
While regulators still argue over 5g safety posters, carriers have quietly slammed the accelerator: capital expenditure on full 5g standalone cores spiked 83% in Q4 2024 versus the same quarter a year earlier, according to fresh vendor data circulating in Barcelona pre-MWC. The cheque books are open because the calendar is brutal—any operator still hugging 4g anchors risks missing the revenue window that must finance 6g R&D now being sketched in ITU drafts.
The 88-club race is on
Only 72 operators boasted a live SA core last November. Today the tally is 88, with North American and EMEA boards leading the sprint. The catch: “deployed” does not mean “exploited”. Most slices remain lab toys, yet the Gulf states have already turned the tech into bragging rights—median SA downloads in Kuwait and Saudi Arabia touch 1.2 Gbps, five times the EU average. European incumbents, tangled in energy costs and merger theatre, now confront a prestige gap that could erode roaming income.
T-Mobile fired the starting gun in the US during 2020; its current 2026 roadmap hints at mass-market network slicing for AR traffic steering. AT&T last month demoed 4 Gbps on a single SIM using 3-component carrier aggregation and a SA core, a speed that turns fibre installers nervous. Verizon pivoted slice talk toward enterprise, selling a guaranteed 50 Mbps uplink for fixed-wireless back-up at $100 a site. Each trial pushes the capex needle higher; Ericsson and Nokia shares have re-priced accordingly.
Europe plays catch-up with helicopters and malls
Telefónica’s answer to Gulf speed kings is vertical. In Ciudad Real the carrier is testing an indoor SA node that hands over to Airbus rotorcraft at 300 m, a stunt meant to prove sub-10 ms handover for emergency drones. The Spanish group’s CAPEX guidance rose 11% for 2025, a rare hike in a region obsessed with dividend cover. Meanwhile Orange and Deutsche Telekom pool R&D in a Franco-German 5G-Hub that swaps code with startups for equity, a tacit admission that buying innovation is cheaper than growing it alone.
The brutal subtext: NSA networks, still the majority, cannot spin up a slice, guarantee latency or bill per service. They are fast 4G, not real 5G. With 6G prototypes demanding AI-native cores, clinging to NSA becomes a technical debt that compounds quarterly. Vendors whisper that the next release of 3GPP already drops some NSA features to cut complexity.
Operators therefore face a now-or-never moment. Slice-based revenue might add 8% to ARPU, according to Ericsson ConsumerLab, but only if the core is SA from handset to gateway. The 83% spending surge is less a triumph than a late cram session before 6G finals. Either the networks pass, or the exam is retaken at satellite-ground blend frequencies that only greenfield players can afford.
Bottom line: the paper-cup phone is not coming back, yet the bill for tomorrow’s sky-high speeds is being written today. Whoever hesitates another upgrade cycle may discover that 6G launch invites arrive addressed to someone else.
