If I reading this right, it seems like you're looking for a setting where "cyberspace" is visible and interactable at any point in the "real world".
Assuming cyberspace means an nonphysical place that can be perceived and interacted with, and that said place has rules of behavior different than those of the real world, I can think of two possibilities.
1) Everyone has a chip in their head. The chip monitors their physical activity and transmits cyerspace directly into their head via a cybernetic link to sensorary areas of their brain. Individuals can chose to be aware, unaware, or half-aware (overlay) of cyberspace. Motion in the real world is accomplished by real motion, motion in cyberspace is accomplished by thinking about motion. Hi-tech wireless lets everyone on the planet be tuned into cyberspace.
2) World-wide holographic projection. Every brick in every building, every tree, every thing has a projector in it. The projector illustrates cyberspace. People interact with cyberspace by moving -- sensors in the projectors read the movement and adjust cyberspace appropriately.
This version is somewhat clunky -- it relies on a very high level of tech, and the planet either has to be bald as a cueball or "cyberspace" has to cloak immoveable objects (rocks, trees, buildings) in immoveable representations, which sort of defeats the point.
Ultimately it comes down to how people interact with cyberspace. The point of it is that it's not the real world -- since people are by nature only attuned to the real world, how do they communicate with cyberspace?
A 3rd possibility is to assume a race of people genetically altered to "tune into" wireless frequencies; this is just option 1 with a wetware chip instead of a hardware chip.
Food for thought, I hope
