Embodiment Construction

[0021] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0022] figure 1 It is a system structure diagram for realizing the access, transmission and signal coverage of CDMA signals in the embodiment of the present invention, and the specific description is as follows:

[0023] The whole system is in a tree structure, and the Main Unit (MU for short) provides multiple branch interfaces downward for connecting the Expansion Unit (EU for short) or the Remote Unit (RU for short). In order to realize more and more flexible remote unit access, the system supports multi-level expansion. At the same time, the main unit can be directly connected to the remote unit without the expansion unit, or connected to the remote unit through the multi-level expansion unit. In this way, the system can realize flexible application. Among t...

Abstract

The invention discloses a system for realizing indoor coverage in a CDMA network. The system comprises a main unit and at least one remote unit, wherein the main unit is used for converting one path of CDMA radio frequency electrical signal received into an optical signal and dividing the optical signal into a plurality of paths of same optical signals for output, and converting the plurality of paths of optical signals received into electrical signals respectively and combining the electrical signals into one path of electrical signal for output; and the at least one remote unit is used for converting the received optical signal into the electrical signal and filtering the electrical signal to filter out a CDMA signal, outputting the CDMA signal after power amplification, and filtering the received electrical signal to filter out and amplify the CDMA signal and converting the amplified signal into the optical signal for output. The system realizes networking of a distribution system, can be flexibly expanded, changes the mode of performing wireless signal coverage dependent on a single power device, provides powerful support and guarantee for indoor coverage construction of a mobile communication network, is energy-saving and environment-friendly, and can reduce repeated construction of a wireless network.

Description

technical field [0001] The invention relates to mobile communication wireless access network technology, especially a system for realizing indoor coverage in a CDMA network. Background technique [0002] With the development of mobile communication networks in China, there are currently more than 600 million users, and the mobile phone ownership rate accounts for more than 45.7%. The entire mobile communication field contains a huge market space. For the more than 600 million mobile phone users who support the development and survival of operators, we can learn from the analysis of their behavior that indoor users are the value of the entire operator. Therefore, in order to attract more indoor users, improving their perception is the focus of operators. [0003] The CDMA network belongs to the 2G mobile communication network and works in the 800MHz frequency band. It is upgraded to CDMA2000 in the 3G mobile communication network and also works in the 800MHz frequency band. ...
