Embodiment Construction

[0150] Embodiments of the present invention will be described below in conjunction with the accompanying drawings.

[0151] LTE air interface standard

[0152] Among many broadband wireless communication systems with mobile communication capabilities, the Long Term Evolution (LTE) technology developed by the Third Generation Partnership Project (3GPP) is a 4G-oriented wireless communication technology. It is especially suitable for realizing broadband wireless communication to aircraft. LTE adopts the air interface design based on OFDM technology, and the goal is to build a high-speed, low-latency, packet-optimized wireless access system to provide higher data rates and spectrum utilization. The LTE system supports both FDD and TDD duplex modes, and optimizes the traditional UMTS network architecture. LTE only includes eNodeB and no RNC; EPC is also greatly simplified. This makes the entire system appear flat. The LTE air interface standard is a fixed broadband wireless a...

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...
