The cell tower is becoming a software subscription

The cell tower is leaving its appliance era — at least, that is the pitch. For three decades, the radio gear between your phone and the mobile network has been a fixed-function box — purpose-built silicon, sold as hardware, upgraded roughly every decade. That model is starting to behave like a cloud server: software-defined, GPU-accelerated, sold as a subscription that can run on a plug-in card, a standalone node, or a partner's cloud.

Nokia's 'more than 20%' spectral efficiency number, reported on its July 15 AI-RAN (AI inside the radio access network) platform launch, is being positioned as the early receipt for that shift — if the trajectory holds. Spectral efficiency is how much data a slice of airwaves can carry; Nokia's own projection puts the ceiling at roughly double existing capacity by 2028, the same physics that took landlines from copper scarcity to fiber abundance.

The vendor-race read is the wrong frame. The Ericsson counter-evidence to Nokia's 'first' claim — a commercial AI-in-RAN software subscription in June — is exactly the point: this is a category, not a trophy. Watch the next 18 months: year-end operator pilots, 2027 commercial availability, and whether the 50% and 100%+ spectral-efficiency targets arrive as vendor slides or as billed capacity. The shift in question is not who is first. It is whether the radio is finally a line item on a cloud bill.
