Radio and telemetry | Focus at 16-17 dB/km in the mmWave band is significantly higher than for the currently used bands below 50 GHz. As antenna sizes are smaller at higher frequencies, the signal margins at 48 GHz and 86 GHz are similar for the same antenna size and channel bandwidth, with the data rate of over 10 Gbps available at the E-band using 256 QAM modulation. This is substantially higher than for the lower bands, due to the greater available channel bandwidth. Even if forced to drop back to older QPSK modulation to improve the signal margin, a 2.5 Gbps data rate can still be achieved. Conclusion A range of radio technologies are boosting the performance of uncrewed systems, both in the air and on the ground. Electronic beam steering can link multiple platforms in the air, or on the ground with mmWave, and the computing power is enabling more complex algorithms. At the same time, cognitive radio is being combined with federated machine learning algorithms and reconfigurable intelligent surfaces to provide more information on the radio environment and optimise bandwidth requirements, redirecting beams, extending battery life and boosting mission times.
