AI Frenzy in Telecom: Huawei, Ericsson, or Nokia, Who Wins?

AI is no longer an incremental network feature. It is changing how telcos invest, where traffic grows, and which layers of the infrastructure stack capture value. Over the last 12 to 18 months, operators have moved from isolated AI pilots to coordinated investment across mobile access, fixed networks, transport, and automation software. This shift explains why Ericsson, Nokia, and Huawei are no longer pursuing similar strategies.Two forces sit behind this change. First, AI traffic growth is reshaping network topology. Training remains centralized, but inference is spreading toward metro, aggregation, and edge locations. This increases demand not only for mobile capacity, but also for fiber densification, high-capacity IP routing, optical transport, and data center interconnect. In many operator budgets, spending growth in fixed and transport now exceeds incremental macro RAN expansion.
