High-Altitude Attritable Link Offset (HALO)

Organization: MIT Lincoln Laboratory
Year: 2016

Designed for use in scenarios where satellite communications are unavailable, High-Altitude Attritable Link Offset (HALO) addresses challenging interference and spectrum-constrained environments. Implementing state-of-the-art hardware and algorithms has proven HALO’s effectiveness in communication for other missions.  HALO enables higher data capacity worldwide and revolutionizes the capabilities achieved by communications relays. Traditional cellular communications use base stations with cell sizes of ~30km and the frequencies are re-used by other base stations 30 kilometers away. HALO allows a set of relays to act as one large array. The array creates small coverage areas, enabling the spectrum to be reused efficiently.
