Doodle Labs’ Front-End Subsystems (FES) leverage Prism technology, which provides flexibility to OEMs looking to continue utilizing their existing wireless radios while shifting the output frequency to anything from 100 MHz – 6 GHz. It is an in-line module placed between the radio and the antenna.
The ScanEagle’s existing radio was a 900 MHz frequency hopping radio. In order to allow operation at 5.2 GHz, the Doodle Labs team developed a customized version of the FES that was optimized and calibrated for operation with the ScanEagle’s radio. Additionally, the Front-End Subsystem operates as a power booster, which significantly improved the range of the ScanEagle.
Prism technology was developed with flexibility in mind for the OEM. Front-End Subsystems are form-factor compatible and can easily be swapped out for others that operate at different frequencies. When Insitu ships to international customers with access to licensed-band frequencies, their operations team simply utilizes the corresponding FES module.
