Wireless communication method

Abstract

The embodiment of the invention relates to a wireless communication method. The method includes the following steps: a first array of optical fibers transmit a first signal optical signal; an opticalsplitter splits the first signal optical signal to obtain multiple paths of identical first branching optical signals; multiple wireless communication nodes synchronously generate the same first pulsesignal, and thus each wireless communication node in a wireless communication array simultaneously and synchronously sends the first pulse signals; a synchronization controller generates a receivingcontrol instruction, and sends the receiving control instruction to a current wireless signal transceiver node through a first signal optical fiber and a first passive optical branching device; the current wireless signal transceiver node receives the first pulse signals simultaneously sent by the multiple wireless communication nodes in the wireless communication array to generate a first communication optical signal; and a second passive optical branching device receives the first communication optical signal sent by the corresponding wireless signal transceiver node and sends the first communication optical signal to a second signal optical fiber.

Description

technical field [0001] The present invention relates to the technical field of communication, in particular to a wireless communication method. Background technique [0002] So far, the purpose of all mobile communication systems is to solve personal communication. Therefore, from the first generation mobile communication system to the current 5G mobile communication system, all the development of mobile communication technology is to improve the quality of personal communication. Therefore, it is unrealistic to try to solve the vehicle-to-ground communication of high-speed trains under wide-area conditions based on the existing mobile communication technology or existing infrastructure. In fact, GSM-R, which evolved from GSM technology, is increasingly unable to meet the increasingly urgent information and intelligent vehicle-to-ground communication needs of high-speed railway transportation, and there is no effective progress in this technology. And the technical progress...

Problems solved by technology

Long-distance wireless communication due to climate change, such as rain, snow, fog and other harsh weather phenomena will not only reduce the quality of wireless communication, but even interrupt communication, so that wireless communication will lose the important support means of high-speed rail informatization and intelligence will directly lead to the failure of high-speed rail informatization and intelligence

[0006] Similarly, although wireless optical communication is not affected by the Doppler effect, it has too high requirements on meteorological conditions and the high complexity of the system. At present, it is not possible to see the possibility of this technology being applied to high-speed rail communication, while satellite communication In addition to the limitation of communication bandwidth, weak satellite signals and too many railway tunnels in high-latitude areas are also the main reasons that limit the application of satellite communication in high-speed rail vehicle-ground communication
