It's easy, you just need a big antenna, low noise receiver (just cool it) for low bandwidth (keeps noise power low) and no interferers in the same frequency band.

Perfect. Now put those on cell phones and make it fit in your pocket.

Technology always gets better with no regard to physical limits.

Just because you call it non-directional doesn't mean it is. They all have gain compared to a theoretical isotropic antenna.
