Embodiment Construction

[0014] The present invention will be described in further detail below in conjunction with the accompanying drawings and specific embodiments.

[0015] A 3G broadband digital ultra-long-distance wireless transmission system, such as figure 1 shown. It includes a near-end machine, a remote machine and a WCDMA data card. The near-end machine is installed on the base station, the remote machine is installed on the service station, and the WCDMA data card is installed on the user end. The near-end machine and the remote machine communicate with each other through the relay antenna, the transmission frequency of the relay antenna is 230MHz, and the WCDMA data card and the service station communicate with each other through the service antenna.

[0016] The 1900~2200MHz high-frequency WCDMA / GSM / DCS signal transmitted by the base station is processed by the near-end machine and becomes an intermediate frequency signal in the 230M frequency band. The intermediate frequency signal is ...

Abstract

The invention discloses a 3G (third-generation) broadband digitalized super-remote wireless transmission system, which comprises a near terminal, a remote terminal and a WCDMA (wideband code division multiple access) data card. The near terminal is communicated with the remote terminal through a relay antenna, the transmission frequency of the relay antenna adopts an intermediate frequency bandwidth, and the information transmission between the WCDMA data card and a service station is performed through a service antenna. Based on the WCDMA interface standard, the near terminal is installed on the existing base station, and the remote terminal is installed on a service tower in remote areas, so that the super-remote transmission of wireless communication is realized, the problem of 3G broadband access in the remote areas can be solved without cable laying, and the coverage rate of wireless network signals in hilly, mountainous and woodsy areas is increased.

Description

technical field [0001] The invention relates to the field of wireless communication, in particular to a communication system based on 3G ultra-long-distance wireless transmission. Background technique [0002] At present, the number of broadband users in remote mountainous areas is small. Due to the difficulty of communicating with the outside world, the information is relatively blocked, and they cannot keep abreast of the actual situation, which has created a major obstacle to information dissemination. The reason is mainly due to the defects of operators in broadband network construction. At present, broadband access can only be realized through cable introduction. Resource expansion is relatively difficult, and the cost for operators is much higher than the broadband usage fee. [0003] 3G is the abbreviation of the third generation mobile communication technology, which refers to the cellular mobile communication technology that supports high-speed data transmission, a...
