Problems solved by technology

The frequency band within 1.5GHz (especially within 1.2GHz) is more useful. The frequency band above 1.5GHz has greater attenuation, poor matching, large reflection, serious multipath, and high development costs.

Abstract

The invention discloses a wireless non-light of sight gigabit Ethernet transmission system based on 700-1100 MHz variable frequency. The transmission system comprises a terminal device and a front-end device. The terminal device comprises a first RF antenna, a first bi-directional RF power amplifier, a first variable frequency transceiver chip, a first baseband data processing chip, an Ethernet function conversion module, a multi-port switch and a first RJ45 interface. The front-end device comprises a second RF antenna, a second bi-directional RF power amplifier, a channel selector, a plurality of transmission channels, a 1000base switch, a master control CPU and a second RJ45 interface. The whole transmitting-receiving process of the Ethernet transmission system adopts a TDD way; the front-end device comprises the transmission channels including variable frequency transceiver chips and baseband data processing chips, so that the data transmission bandwidth can be multiplied; frequencies are only emitted by one transmission channel at the same time, so that same frequency interference is avoided; and multi-channel Ethernet data are aggregated under the coordination of the 1000base switch.

Description

technical field [0001] The invention relates to the technical field of wireless broadband long-distance Ethernet transmission, in particular to a wireless non-line-of-sight gigabit Ethernet transmission system and a transmission method based on a variable frequency of 700MHz-1100MHz. Background technique [0002] The wireless Ethernet broadband transmission technology currently used in the market is mainly based on the frequencies of 2.4GHz and 5GHz and LTE used by cellular mobile phones. The frequencies used by these technologies are relatively high, and the advantages are that the signal is stable, the interference received is small, and a small receiving antenna can be used. But the disadvantage of this frequency is also obvious, because frequencies exceeding 1GHz are easily absorbed by air, buildings, and plants, so they cannot be transmitted over long distances. [0003] my country's cable TV standard stipulates that the frequency band below 860MHz of the coaxial cable...
