Abstract

The present invention provides a captive balloon communication system, the communication system comprises a ground support system, an RRU and a BBU; the RRU is disposed on a balloon, the BBU is disposed on the ground and the RRU forms a split base station, or the BBU is disposed on the balloon and forms an integrated base station with the RRU, the ground support system and the balloon are connected by a cable, the cable is provided with an optical fiber, and signal output of the BBU is transmitted through the optical fiber, and the optical fiber transmits baseband IQ data and OAM signaling data of the BBU to the RRU. The captive balloon communication system allows increasing balloon height, so that coverage distance is greatly increased, and reduces an interference path of multipath interference. The captive balloon communication system can effectively reduce influence of the radius of curvature of the earth on communication. The low-band frequency allows the signal to be transmitted beyond line of sight transmission, and the signal will be as far as 120km to 300km.

Description

technical field [0001] The invention relates to a tethered balloon communication system, which belongs to the technical field of tethered balloon communication. Background technique [0002] Humans live on land, and most of their activities are not far from the shore. Therefore, solving offshore communication is the first and very important step. The current marine communication technology originated from the Morse telegraph in those days and developed slowly. [0003] Among them, MF / HF and VHF are severely limited by narrow bandwidth, can only provide end-to-end voice communication, and communication can only use public channels, which are easily interfered by other ship communication. Coast stations also have insufficient channel resources. For example, Tianjin Coast Station and Fuzhou Coast Station use channel 813 at the same time. Any group of calls may affect the communication of other ships. There are often crew members who call their families through the coast radi...
