Telephone networks have evolved from elaborate centralized switching equipment connected to phones that were nothing but simple input/output devices, to modern mobile networks where most of the application functionality resides in handheld devices at the edge of the network.

This is a prime example of how decentralized architectures that distribute processing power closer to the point of use are inherently more efficient because they remove the problems of distance. Removing distance as a factor simplifies the overall design and significantly improves response time, which contributes to improvements in productivity.

The issue of removing processing distance is especially relevant to vacuum technology, because the more distance there is between the vacuum source and the point of use, the more energy is consumed and thus, the more expensive the cost of production becomes.
