Similarly to MASC-Assisted Laser, MASC-Assisted Radio employs advanced space compression to extend the effective range of radio-based communications. It generates a nanoscopic corridor that can safely penetrate large stellar bodies that may be in the path of the transmission, and allows communications to be made a many thousands of times at the speed of light. Transmissions of this type can only be projected effectively up to 20 LY, but within this range, these communications are nigh instantaneous. Unlike laser, which has to be specifically directed to a certain location, MASC-radio is capable of broadcasting to targets within a range estimated at half of one light-second.

Radio is much easier to intercept than laser, but can still be viable in combat situations through the judicious use of encryption keys. All MASC-enhanced communications systems may generate minor signatures that can be picked up on by distortion or Vector Wave Sensors in a short range.
