The US Department of War has chosen Cohere Technologies for a contract worth US$28m to build a Multi-Waveform Radio Access Network prototype for Integrated Sensing and Communications (ISAC). ISAC technology allows mobile networks to transmit data whilst simultaneously detecting physical objects, with demand accelerated by drone warfare tactics used in the Russo-Ukrainian conflict. Cohere has developed an alternative waveform called Zak-Orthogonal Time Frequency and Space (OTFS), which forms the basis of its Pulsone Technology and delivers four times better performance than OFDM for target detection and tracking multiple simultaneous targets. The FutureG Office within the Department of War is funding the contract, which expands on a National Science Foundation VINES Phase 2 project. Cohere describes the system as a sovereign, mission-first ISAC capability using existing and future commercial 5G and 6G infrastructure for persistent aerial and ground surveillance. Tom Rondeau, Principal Director for FutureG, says ISAC is a mission-first priority to defend against drone swarms, and Cohere offered a clear path that could be moved on immediately.
