Etherstack received a contract extension from the Swedish Defense Materiel Administration to supply technology and engineering services to support further development of a software-defined radio (SDR) platform used by the country's military. The SDR platform is compatible with the software communications architecture developed by the U.S. Department of Defense's Joint Tactical Radio System program.

The goal is to enable protocol stack developers to engineer air-interface-signaling software that can run on multiple radio manufacturers' equipment. This would let single devices host multiple waveforms and then communicate across disparate platforms, according to Etherstack. Under a previous contract, Etherstack had adapted part of its TETRA Mobile Station protocol stack for use in the SDR platform.
