Wireless communication system and method for supporting access of multiple communication systems

Abstract

The invention discloses a wireless communication system for supporting access of multiple communication systems. The wireless communication system comprises multiple access units, at least one extension unit and at least one remote unit, wherein the at least one extension unit is respectively connected to each access unit; the at least one remote unit is connected with the extension unit; various access units respectively support multiple communication modes of different operators; various remote units respectively support multiple communication systems of different operators; in a down-link, each access unit sends a received radio-frequency signal to each corresponding extension unit through micro-wave after adding a corresponding communication system label into the received radio-frequency signal; each extension unit sends a received micro-wave signal to the remote unit supporting the communication system after processing the received micro-wave signal according to the communication system label in the received micro-wave signal; and the remote unit processes the received optical signal, converts the received optical signal into the radio-frequency signal in the corresponding communication mode, and transmits the radio-frequency signal to users.

Description

technical field [0001] The invention relates to the field of electronic equipment, in particular to a wireless communication system and method supporting access of multiple communication standards. 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 ser...
