The FAA so far has refused to let Lightsquared deploy a satellite system due to concerns it will interfere with the GPS transmissions. Nothing beats the efforts to design in good technique.

Thank you. The industry is continuing to research new modulating schemes. Multiple antenna schemes are being deployed. I like your thought. The more intelligent the filtering, the further we can go.

ha ha,, liked you're comment sharp! is good to think about the future... Perhaps a better filtering scheme will come out that will allow us to keep on going wireless... or modulating scheme.

- and as we push the boundaries to produce more and more cheaply-made digital logic-driven devices and wireless gadgetry we are adding to the background noise at a fantastic rate, 10dB every few years. Thresholds are falling, noise rising, we are going to run out of SNR real soon and no amount of diversity, eye diagrams and microvoltmeters will help. Finally we are going to have to pay attention to shielding, EMI design, precision filters and regulatory compliance just to get the simplest thing to work in this Tempest of our own making. Only then, maybe, the unintended emitted noise will start to fall, and the power necessary to transmit useful signals will reduce, and a virtuous circle will be created to get us to where we should have been in the first place. Funny old world, innit?
