$GTCH SAN DIEGO, Feb. 08, 2022 (GLOBE NEWSWIRE) -- GBT Technologies Inc. (OTC PINK: GTCH) ("GBT” or the “Company”), is providing an update about the continuation of its efforts to evaluate Software Defined Radio (SDR) technology for its GEN II long-range radio system. SDR communication is a software-controlled radio operation. A typical RF system is traditionally operated via hardware using radio modules and components. SDR technology is a computer-controlled RF system. GBT is now evaluating the capabilities of using SDR to enable the creation of an intelligent, software controlled, HF communication system. GBT’s Infinia (internal project’s code name) is a data and voice communication project that operates using High Frequency (HF) radio waves. Infinia communicates through ionospheric propagation environment to reach very long distances.
