You’re right, something like what I described wouldn’t necessarily need networking to work like that. However, think if you had to manage 100 or more of these devices for people in an assembly plant. Deploying new torque specs to all of the workers’ tools wirelessly would be much faster than having them bring them in individually after each batch job had been completed.
