$GTCH The unit is designed to communicate in the HF (High Frequencies) frequencies bands to establish connection with a base unit transceiver through repeater unit(s) to reach ultra-long range. High clarity, signal reliability and security is expected to be achieved through the implementation of advanced circuitry within the system’s components. The design includes embedded software to manage the data and audio communication including data transfer to a backend server to process data. The design also provided for the mobile unit’s design, size and interface, taking into consideration performance and mobility. The operation of the mobile unit is expected to be done via an LCD touch screen providing user’s friendly interface and ease of use. Upon getting team’s FCC certification, an extensive mobile unit’s testing will start. GBT plans to test the entire system within a large city limits and national ranges.
