Problems solved by technology

However, due to the relatively high price of photoelectric converters, when the number of RRU / remote units used is large, the total cost will be high
For an indoor distributed system, when multiple RRUs / remote units are used on each floor, it is necessary to increase the optical fiber wiring from the weak current well to the RRU / remote unit, which increases a certain amount of engineering, reduces the speed of network deployment, and increases netting time

Embodiment Construction

[0023] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0024] see figure 2 , which is the basic interface diagram of the present invention. For the radio frequency remote equipment at the antenna port, while completing the radio frequency processing and analog-to-digital conversion, the digital electrical signal is obtained according to a certain protocol and sent to the twisted pair. The electrical signal may be a high-speed electrical signal or a low-speed electrical signal, without limitation. After the conversion device receives the electrical signal sent from the twisted pair, it performs multiplexing / demultiplexing or digital combining / distribution processing on the signal, and then performs photoelectric conversion on the processed electrical signal according to a certain format, and will get The optical signal is sent to the near-end processing device unit through the optical f...

Abstract

This invention discloses a RF remote distribution system in the radio communication system including: at least one RF remote device connected with a converting device, which is connected with a near end process device, and the RF remote device and the converting device are intercommunicated by ordinary twisted-pair lines at low speed electric signals, and the converting device is used in finishing conversion of RF remote devices and near process devices and placed at a gathered place of five kinds of twisted-pair lines of RF remote devices or a position owning gathered interfaces of fiber and the twisted-pair lines at the same time since large amount of the interfaces are set in a building and the RF remote devices are placed at needed positions by the interfaces.

Description

technical field [0001] The invention relates to a radio frequency remote device distribution system, in particular to a distributed coverage network of 2G and 3G (second generation and third generation wireless communication systems) in the field of wireless communication. Background technique [0002] With the development of 3G technology, in order to solve the RF power loss caused by the feeder, there is a distributed solution of BBU (baseband pool) + RRU (radio remote unit). This solution usually connects the BBU and RRU through optical fibers. In addition, the repeater system currently also has a digital optical fiber repeater system, and the near-end unit and the far-end unit are also connected through optical fibers. The block diagrams of the two systems are attached figure 1 . However, due to the relatively high price of photoelectric converters, when the number of RRUs / remote units used is large, the total cost will be high. For an indoor distributed system, when...
