Wireless communication system and method for realizing multiple communication standard access

Abstract

The invention discloses a wireless communication system realizing access in multiple communication modes. The wireless communication system realizing access in multiple communication modes comprises multiple access units which are sequenced one by one based on the priority, at least an extension unit connected with the access unit with the highest priority, and at least a remote-end unit connected with the extension unit, wherein each access unit supports multiple communication modes of different operators; in a downlink, each access unit forwards received radio frequency signals which are added with a corresponding communication model label and optical signals with a communication mode label sent by the access unit with the priority one level lower to the access unit with the priority one level higher, and the access unit with the highest priority finally converts the received radio frequency signals which are added with the corresponding communication mode label and the optical signals received from the access unit into microwave signals and transmits the microwave signals to each corresponding extension unit; each extension unit after performing data treatment on the received microwave signals transmits the processed microwave signals to each remote-end unit through an optical fiber; each remote-end unit processes received optical signals, converts the optical signals into radio frequency signals in the corresponding communication mode and transmits the radio frequency signals to a user.

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 multiple communication standard 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 are many standards...
