And, once you got interplanetary (and interstellar) broadband, the basis for a star-spanning Internet.

Call it Interspace. :)

[In the] 2520s: On Earth, on other worlds and between them, yet another threshold was reached: the development of Interspace, a nearly instantaneous form of virtual reality that made not only interplanetary but interstellar commerce (and micrommerce) possible and profitable. It was Internet taken to the next level; virtual tourism of other worlds, use of Waldos (rental androids and gyndroids) to 'be there' on other planets, or operate machinery, participate in conferences, gatherings, social events all supported by broadband photon entanglement. The system worked best between worlds where photon-entangled nodes had been swapped the old-fashioned way -- carting them out on starships, or fast-flinging them at near-lightspeed like the old Surveyors of the Celestial Survey, and kept up a steady stream of refresher qubits, to maintain and upgrade connectivity.

In this fashion, for the first time, residents of Earth viscerally connected to their cousins elsewhere, and felt immediacy about events in the wider universe. America was the pioneer in this field, again due to centuries of particular advantage in computer and network systems, quantum simulations, and virtual reality. The Russians would assume parity in the 2540s, then the Australians in the 2550s. The ultimate champion, due to centuries of leadership in interstellar communications and its prior role as the headquarters of the Celestial Survey, would be Puerto Rico. Arecibo in this time was a city of two million and home to almost half of the island's population, its core economic activity being the processing, launching, monitoring and maintenance of the infrastructure that literally wove the stars together.
