1. A system for broadband wireless access communication between ground terminals and a network of one or more drones, comprising:
at least one antenna fixture on each drone capable of generating at least one beam toward the ground, forming beams toward terminals located in a wide area on the ground; at least one radio sub-system on each drone with a receiver for demodulating and decoding signals received from the ground terminals, a transmitter for modulating data and transmitting the modulated signals to ground terminals through at least one drone antenna, sending at least one pilot signal to ground terminals, and controlling and configuring the drone antenna to form beams in specific directions; at least one drone switching sub-system with capability to switch data received at the drone from one set of terminals on the ground to another set of terminals; an antenna sub-system at the ground terminal with capability to point beams toward specific drones; and a radio sub-system at the ground terminal with a receiver for demodulating and decoding signals received from drones, a transmitter for modulating ground terminal data and transmitting the signals to drones through the ground terminal antenna, sending at least one pilot signal to drones, and controlling and configuring the ground terminal antenna to from its beam toward drones. |
