[QUOTE="SelfSim, post: 77651155, member: 354922"] On the contrary, the criteria around reception distances of RF sytems, has been known since RF comms has been around. Extracting a hypothetical RF pattern from the noise background, becomes the key limitation for a potential ETI enthusiast .. apart from hypothetising what such an ETI signal, (the hypothetical pattern one is looking for), would look like in the first place. In laser based comms, distinguishing bright pixels in the Rx imager and distinguishing the cause of these from natural High Energy Cosmic Ray 'hits', then becomes its limiting factor. The distances achievable are far greater than for RF comms though. [/QUOTE]
