How is UAV wifi image transmission realized?

Uav varieties are divided into many kinds, military, common, civil, police, etc., but also because the UAV flight range is very broad, the reason for the random change of the place of flight, the wired transmission method can not be completed, therefore, the wireless transmission signal skill has become the only way to control the UAV.

Wireless image transmission is mainly 1.2GHz, 2.4GHz and 5.8GHz these three bands, of which 2.4GHz this band is now very crowded, Wi-Fi(other than 802.11ac), Bluetooth, wireless mouse are concentrated in this band region work. While 1.2GHz is a regulated band in most parts of the world, the 5.8GHz band currently has very little interference. Therefore, nowadays, the drone wireless image transmission mostly works in the 2.4GHz band and the 5.8GHz band.
