From their report: > We have run link margin calculations including Zodi, CIB, galaxy and optical emission for such a wafer scale system run in a hibernate/burst mode using the DE-STAR array as both the transmitter of power to propel and communicate with the spacecraft as well as to receive the very weak signal from the spacecraft and conclude it is feasible to receive data (albeit at low rate) at light year distances.
