    Unmanned Aerial Vehicles (UAVs) have tremendous applications such as agriculture, commercial, scientific activities, policing, recreation, servile, delivering goods, photogrammetry etc. But there are many challenges to operating UAVs for variation of weather. When used it vastly, there is a challenge of management of UAVs because of limited bandwidth. In this case, we have proposed a dual band UAV i.e mm wave and microwave. Generally, the bandwidth is more in mm waves than microwave frequency band. So, we surely communicate in mm wave frequency bands. But the Signal-to-Interference-Noise-Ratio(SINR) value is less at high frequency. The UAVs communication is poor at frequency more than 54 GHz where the Signal-to-Interference-Noise-Ratio(SINR) value is less than the average threshold SINR value about -75.97 dB. Then we will switch to the microwave frequency band. The Channel switching mainly depends on the respective bandwidth. Generally, UAV uses 2.4 GHz bandwidth
