The modern battlefield is full of robots all talking at once. Unmanned systems consume significant amounts of communications bandwidth because they require transmission of control signals and large amounts of sensor data. Line-of-sight (LOS) limitations often obstruct high frequency digital radio communications. In addition, encryption, which is necessary for security, can decrease operational distance.
Besides compromising range, radio noise may also affect how the robots respond toinstructions, even instigating false commands. Another consideration is the additional power consumption necessary to burst through interference.
Different types of unmanned systems have specific radio communication challenges….
