Ground-air broadband wireless communication system and method for airplane

Abstract

The invention discloses a ground-air broadband wireless communication system and a method for an airplane. The system comprises a plurality of long term evolution (LTE) ground base stations installed along a predefined airway and an LTE communication terminal on the airplane, wherein an overlapping communication coverage area is arranged between adjacent LTE ground base stations, the base stations perform wireless launch and receiving according to an LTE wireless air interface protocol, and the LTE communication terminal performs wireless launch and receiving according to the LTE wireless air interface protocol to build high-speed two-way communication links with the ground base stations; and additionally, a plurality of airplane radio frequency antennas are arranged on the outer surface of the airplane and connected with the LTE communication terminal through interconnection wire cables. Each ground base station is provided with radio frequency antennas with the same polarization, the radio frequency antennas with the same polarization are directional antennas with a certain beam broadband, and the LTE communication terminal receives radio frequency signals launched by the ground base stations and launches radio frequency signals to the ground base stations through the plurality of airplane radio frequency antennas.

Description

technical field [0001] The invention relates to the field of wireless communication. More specifically, the present invention is a ground-to-air broadband wireless communication system and method for aircraft. Background technique [0002] For society, high-speed data communication is becoming more and more important and has become an indispensable element in people's social life. Most of today's high-speed data connections are based on physically connected lines, such as twisted-pair cables, fiber optics, etc. Wired connections are difficult to use in situations that require mobility, so data communication based on wireless technology is very attractive for passengers on airlines. However, the high-speed wireless data connection is difficult to meet the coverage distance requirement for actual flight use. An alternative is to provide aircraft with a high-speed link via satellite. This scheme has many disadvantages: first, its transmission rate is very limited, resulting...

AI Technical Summary

Problems solved by technology

This scheme has many disadvantages: first, its transmission rate is very limited, resulting in high cost per bit of data transmission; second, satellite-based schemes require special antennas and corresponding airborne equipment, which are very expensive , does not have a corresponding cost advantage; finally, the satellite-based data communication solution requires too long an aircraft modification time, usually about 1 week

According to the requirements of airworthiness regulations, aircraft that have not been modified cannot be used for flight transportation
