Wireless communication system and method for realizing multi-channel different-site information source access

Abstract

The invention discloses a wireless communication system realizing multipath different-address information source access. The wireless communication system comprises a main access unit, a plurality of slave access units respectively connected with the main access unit, at least one expansion unit connected with the main access unit, and at least one far-end unit connected with the expansion units, wherein the main access unit and the slave access units respectively support a plurality of communication standards of different service providers; in a down link, the slave access units respectively add corresponding communication standard labels to received radiofrequency signals and send the radiofrequency signals to the main access unit through an optical fiber; the main access unit adds corresponding communication standard labels to received radiofrequency signals, converts the radiofrequency signals and the optical signals from the slave access units together into microwave signals and sends the microwave signals to each corresponding expansion unit; the expansion units respectively carry out data processing on the received microwave signals and send the microwave signals to the each corresponding far-end unit through optical fibers; and the far-end units respectively process the received optical signals so as to convert the optical signals into radiofrequency signals of the corresponding communication standards, thereby enabling the radiofrequency signals to be sent to users.

Description

technical field [0001] The present invention relates to the field of electronic equipment, in particular to a wireless communication system and method for realizing multi-channel different address information source access. Background technique [0002] After years of long-term development in China's communication industry, a situation of 2G / 3G / 4G coexistence has gradually formed. Mobile communication signal transmission is transmitted through a certain frequency, and the frequencies and network standards owned by the three major operators are not the same. At present The formats already in use in the market are: [0003] China Mobile: GSM800, GSM1800, TD-SCDMA, TD-LTE; [0004] China Unicom: GSM800, GSM1800, WCDMA, TD-LTE, FDD-LTE; [0005] China Telecom: CDMA, CDMA2000, TD-LTE, FDD-LTE. [0006] The above does not include the excessive standards produced by various generations of communication technologies during the speech process. It is not difficult to see that there...
