You have to step back from the whole concept surrounding wireless communications, and really weigh the fundamental principles at work to consider the realities of the universe we inhabit, which is totally weird and doesn't at all stand up to ideas one might consider "normal" or reasonable.
The idea of wireless communication is only just a little bit more glamorous, because it's really the only thing that will assist humanity as part of space travel. And because we know light signals have pretty high fidelity across vast distances of (mostly) empty space.
But, solid state conductors, even if not purely contiguous due to repeaters and amplifiers, still seem pretty rational, when you start to think about what conductive transmission mediums actually do, especially as compared to emission filaments and diodes as broadcast signal sources.
- mjevans 9y agoYou're close to why point to point connections have an advantage, well two. Fixed links mean the signal can be narrowed so that less other things interfere with it and it interferes less with other things. There isn't contention or the crowded room effect (like an apartment complex stuffed with WiFi nodes). The fixed nature also allows for a more optimal end point configuration. (Lower power, longer distance, etc)
- pavement 9y agoYep, right out of the box, the clear advantage is no deliberate signal jamming with a malicious high volume noise floor, no line of sight requirements for directional signals, and lower incidental destructive interference from sharing the medium, reducing dependence on digital signal processing filters.
