Networks as compute layers
Telecommunications infrastructure is
evolving to support this shift.

Towers, base stations, and regional
exchange points are starting to
carry compute workloads alongside
connectivity. This makes existing
infrastructure part of the processing
layer.

Instead of relying only on large,
centralised facilities, capacity is
distributed across multiple points. Each
node handles part of the workload,
reducing pressure on the core network.

the same thing. Systems must continue
working even when the network does
