Abstract: A method, apparatus and system for extended wireless communication include an airborne platform including at least one antenna to pick up and radiate wireless signals, a platform controller to control the altitude and attitude of the airborne platform, and a communication payload. In an embodiment, the communication payload includes at least two transponders to establish wireless links and a controller having a processor and a memory coupled to the processor. In some embodiments, the memory has stored therein instructions executable by the processor to cause the airborne communication system to elevate the airborne platform to an altitude at which wireless connectivity is able to be established with a first wireless network, establish a first wireless link to the first wireless network, establish a second wireless link, and relay data between the first wireless link and the second wireless link.
