Dell’Oro Group revealed mobile operators have spent 208% more on standalone (SA) 5G than they had on 4G core functions at the same point in the technology’s lifecycle.

The company stated the long-term outlook for SA 5G technology is good, despite forecasting growth in the core network sector to moderate over the next two years.

In a report, the company stated the substantial financial commitment on SA 5G highlights the inherent architectural complexity and the broader strategic value of next-generation core networks compared with LTE deployments.

Explaining the timing behind the investments, senior director Sian Morgan noted the sequential release of 3GPP standards created an initial offset between early 5G RAN spending and deployment of SA cores.

Despite those early delays, the technical sophistication of SA 5G “is driving cumulative vendor revenues much higher” than LTE evolved packet core achieved at an equivalent point in its deployment timeline.

Morgan said SA 5G revenue is yet to reach its peak because the majority of mobile operators worldwide have yet to make commercial services widely available to customers.

Dell’Oro noted near-term headwinds as memory shortages drive server prices up, prompting operators to scrutinise project costs.

Morgan predicts a return to double-digit revenue growth in 2028.

Dell’Oro forecast growth in the next five years to be fuelled by the EMEA region. It increased its expectations for 4G core revenue after gains in 2025 and identified AI as providing opportunities to boost efficiency, though warned over potentially higher costs.
