some notes
Some human-made common-pool resources are renewed very rapidly once use has halted or been reduced. Broadcasting bandwidth, for example, is a common-pool resource because it is limited, one person’s use is subtractive, and thus congestion can occur if too many users try to use the same bandwidth at the same time. The resource regenerates immediately, however, when usage declines, so subtractability exists across users, but not across time. Such commons cannot be destroyed permanently by overuse.

On the one hand, it shows that that the aggregate throughput ca-
pacity, measured as the sum of individual throughputs, can
scale linearly in the number of nodes. On the other hand,
the result underscores the importance of choosing minimum
power levels for communication and suggests that simply
communicating with the closest node or base station could
yield good capacity even for multihop hybrid wireless net-
works.

Elinor Ostrom views broadcast bandwidth as a finite resource - but this is dependent on network topology. Kumar shows that total throughput in a mesh network can scale linearly with node numbers - the more nodes the more total throughput.
While radio spectrum is a common pool resource - the technological implementation of transmitters and receivers determines whether one should treat radio spectrum as a subtractive common pool resource, a renewable common pool resource or an additive common pool resource. By using appropriate technologies and mandating these through protocol, policy or simply marketing scarcity can be avoided in the creation of an additive common pool resource of radio spectrum.
