3 Radio Design Challenges for Satellite D2D/IoT Service Link

Satellite D2D and IoT services introduce unique radio design challenges. Unlike traditional satellite services that use dedicated terminals with directional antennas, D2D/IoT systems communicate directly with smartphones or compact, low-power IoT devices. These devices have limited transmit power and small, low-gain antennas, while the satellite can be hundreds or thousands of kilometers away. Closing this challenging link budget while minimizing payload size, weight, and power (SWaP) places significant demands on the satellite RF architecture.
