The important question we consider in this chapter is how to insure any future interstellar radio links between the Solar System and future interstellar probes. We show by calculations that only by exploiting the gravitational lens of the Sun as a huge antenna will we be able to achieve such an interstellar link. In other words, we calculate the bit error rate (BER) across interstellar distances both with and without using the gravitational lens effect of the Sun.
