This all-encompassing... «e-topia»
abyssus17 октября 2014This all-encompassing digital system will create new linkages between cities and within cities, and its intercity and intracity components should carefully be distinguished. To begin with, there are significant technical and cost differences among local-area, metropolitan-area, and long-distance networks. But more importantly, they differ in their implications for urban life and form.
Long-distance, intercity linkages are formed by interconnecting major switching centers with high-capacity fiber-optic cables, microwave links, or satellite links to create digital telecommunications backbones. The switching centers are usually known as POPs— points of presence. If they are on backbones that run at gigabit rates, they are gigaPOPs. And large centers built around satellite earth stations have sometimes been promoted as teleports.
