Network signal coverage system based on stratospheric airship

Abstract

The invention discloses a network signal coverage system based on a stratospheric airship. The stratospheric airship is arranged on a stratospheric layer; the network signal coverage system comprisesa transmitting device, a relay device and a receiving device; the transmitting device receives a network signal; the transmitting device transmits a wireless signal to the stratospheric airship according to the network signal; the relay device is arranged on the stratospheric airship; the relay device receives the wireless signal; the relay device transmits a relay signal according to the wirelesssignal; the receiving device is arranged in a coverage range of the relay signal; the receiving device is towards the relay device and receives the relay signal; the receiving device shares a hotspotsignal to surroundings according to the relay signal; any terminal device within a coverage range of the hotspot signal receives the hotspot signal; the terminal device is in communication connectionwith the receiving device by virtue of the hotspot signal; and the terminal device is accessed to the network signal by virtue of the hotspot signal. According to the network signal coverage system provided by the invention, the action distance is far, the signal coverage range is wide, the system position is set flexibly, the system cost is low, and the deployment and the maintenance are easy.

Description

technical field [0001] The invention relates to the technical field of wireless communication, in particular to a network signal coverage system based on a stratospheric airship. Background technique [0002] Stratospheric airship data transmission refers to the communication method of setting up wireless bridges on the stratospheric airship platform to provide WIFI signal coverage, data transmission and other services for ground users. It is considered to be a data transmission method with great potential in remote areas . Compared with traditional ground base stations, building a network coverage platform on a stratospheric airship has the advantage of a height of 20KM. The distance between the platform and the ground is much lower than the height of various communication satellites, which can reduce the attenuation of signals during free space propagation. Shortening the signal delay time is conducive to the miniaturization and broadband of communication terminals, the s...

Problems solved by technology

[0003] The road-based cellular system of the prior art has the following defects: 1. Although the propagation delay is small, the frequency selection and transmission rate are severely limited, and the signal coverage cannot meet people's needs; 2. The road-based cellular system is based on satellite communication, and satellite communication Large propagation delay; 3. The propagation delay of LEO (low-orbit satellite) is small, but multiple LEOs must work at the same time, and the expansion of the system must add satellites, and hardware upgrades require replacement of satellites; The use environment is not easy to deploy; 5. The roadbed honeycomb is large in size and high in cost
