Multi-service wireless communication system and method

Abstract

The invention discloses a multi-service wireless communication system and method. The multi-service wireless communication system comprises a plurality of access units, at least one expansion units connected with the access units, and at least one far-end unit connected with the expansion units; each access unit supports a plurality of communication modes of different server providers, and each far-end unit supports the communication modes of the different server providers; in a down link, each access unit adds a corresponding communication mode label to a received radio-frequency signal and then sends the radio-frequency signal to the corresponding expansion unit through a microwave; each expansion unit processes the received microwave signal according to the communication mode label in the received microwave signal and then sends the processed microwave signal to the corresponding far-end unit supporting the communication mode through an optical fiber; and the corresponding far-end unit processes a corresponding received optical signal to convert the corresponding received optical signal into a radio-frequency signal in a corresponding communication mode and to transmit the radio-frequency signal in the corresponding communication mode to a user.

Description

technical field [0001] The invention relates to the field of electronic equipment, in particular to a multi-service wireless communication system and method. 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 are many standards in service in the Chinese communication indust...
