Three telecom developments point to AI infrastructure being built into fibre networks and mobile systems, as well as data centres. The most measurable result is a reported 20% improvement in spectral efficiency in an O2 and Nokia trial at London Paddington.

What happened
Verizon has signed a deal worth more than $2bn to supply Amazon Web Services with dark fibre for AI workloads, according to TelecomTV. The company also reported an active pipeline of other large customers in talks about fibre connectivity.
O2 and Nokia trialled AI-RAN at a London Paddington site, where the report says spectral efficiency improved by 20%. That measure describes how efficiently a network uses its radio spectrum. O2 says the trial also improved throughput and kept the network stable during periods of high demand.
Separately, Tata Communications plans to invest around $450m in a 10,000km fibre network linking Indian data-centre corridors. The report describes the network as supporting AI data centres.
Why it matters
AI infrastructure is not only a race to secure accelerators and build data centres. It also needs the fibre and mobile networks that move data between systems and serve users. These announcements show three different parts of that build-out: a hyperscaler buying connectivity, an operator testing network optimisation, and a planned national fibre expansion.
The figures are company statements and reported trial results, not independent comparisons. Still, the O2 result gives the network story a practical measure beyond the usual promise that AI will make everything more efficient. The tougher test is whether such gains hold up outside a trial.
Our read
The striking point is how much of the AI build-out is becoming a telecoms story. Fibre is usually invisible until it is missing; now it is being presented as a strategic input to AI workloads. The O2 trial is the most immediately testable claim here, while the two investment plans will have to become deployed capacity before the numbers mean much.
What to watch
- Whether Verizon turns its reported pipeline of prospective customers into further contracts.
- Whether O2 publishes more detail on how it measured the 20% spectral-efficiency gain.
- How Tata’s planned network is phased and when its first links are expected to be ready.
Discussion spark: As AI demand grows, should telecom operators prioritise building more fibre and capacity, or invest first in systems that make existing networks work more efficiently?
