These are all very synomous with people doing presentations on windows. Likely because due to its supposed user-friendlyness, it attracts a largely poorly skilled user base, those that would make the above mistakes (over and over again).
If a user has the skills and motivation to install linux and configure it properly most likely have the foresight to avoid such errors.
Although I may not agree with all that this article said, I think the point he is trying to get accross that the limit is not on nature but on our technology. An infinite(unlimited) number of transmissions can be sent on a given frequency, better technology just needs to be developed to discern between them. We will obviously never reach inifinitey or even likely a really high number, but with the current regulations we will never have the motive to develop technology to handle more than one.
I am no expert here, so take what I say with a grain of salt, or a shot of JD whichever you prefer. As outlined by others here, if two transmissions (A and B) are received on the same frequency a conventional receiver is listening on, the perceived signal to the receiver is the sum of both transmissions (A+B). When listening to radio, this sounds like two stations superimposed on each other, because it is. I believe conventional radio receivers simply monitor the current induced on a piece of metal (antenna) by the electromagnetic waves passing by. Through some nice circuitry you can 'tune' into a certain frequency and route that to an amplifier and speaker. This method inherently limits Reeds statements as the antenna is in fact measuring the modulating magnetic field at that point in space, a natural effect of the photon/wave passing by. There is no way to distinguish between two signals beyond this point(antenna) as this value is a scalar, a simple measurement, like temperature at a certain point in space. However, if we could develop another way to read these signals, some sort of photon detector (I think there is work being done on these), we could significantly increase the number of signals we could distinguish on a single frequency. If our signal is thought of as a finite series of photons with a given energy level and distribution (I am not so sure it can be), then could we not separate multiple signals/streams through timing. We expect the photons to be a certain time frame apart, photons outside of the expected timeframe are either part of another stream or have been reflected or altered in such away they are no longer relevant to the current stream.
This sounds all fine, however assumes that photon interference does not occur and thus does not explain all those interference experiments I did in physics labs involving single slits, double slits, thin films etc. Although, I have read about the statistics properties of these effects in such that the same effect (double slit interference pattern) can be observed if a single photon is sent through once a second. If the photons are not actually interfering with each other, is there an effect of having two 'streams' overlapping? Those more knowledgeable of quantum mechanics would likely have greater insight into this, and I would be glad to hear it.
