Voice broadband wireless ad hoc network radio station

Abstract

The invention provides a voice broadband wireless ad hoc network radio station, and relates to the technical field of radio stations, and the voice broadband wireless ad hoc network radio station comprises an analog signal conversion module which is used for converting a digital voice signal into an analog voice signal, and packaging the analog voice signal into a data packet; and the digital signal conversion module is used for converting the simulated voice signal into a standard TCP / IP data packet. According to the radio station disclosed by the invention, a wireless ad hoc network radio station of an IP unvarnished transmission system is fused with a traditional analog telephone switching technology, and an ad hoc network radio station based on Ad-Hoc and Mesh architectures is adopted, so that IP data and analog voice data are fused on the basis of satisfying large bandwidth and high mobility; the broadband IP data and the analog voice data can be transmitted by one device at the same time, in addition, the cognitive radio technology is adopted, the characteristics of external interference signals can be actively monitored, the working frequency points can be dynamically adjusted according to the monitoring result, the anti-interference performance is high, and the advancement is remarkable.

Description

technical field [0001] The invention relates to the technical field of radio stations, in particular to a voice broadband wireless ad hoc network radio station. Background technique [0002] During field operations, drills and emergency communications, it is often necessary to extend the telephone from the node of the program-controlled switch to the work area. At the same time, various types of data transmission, including video and images, require relatively large bandwidth. Currently, existing There are two types of equipment. One is equipment for professional voice transmission, such as telephone optical transceivers and PCM equipment. It must rely on optical cable communication and is not suitable for use under complex terrain conditions. The second type is wireless transmission equipment. This type of equipment is mainly based on multi-carrier modulation wireless transmission equipment based on the IP system. At present, such equipment cannot directly connect to analo...

[0002] During field operations, drills and emergency communications, it is often necessary to extend the phone from the node of the program-controlled switch to the work area. At the same time, various types of data transmission, including video and images, require relatively large bandwidth. Currently, existing There are two types of equipment. One is equipment for professional voice transmission, such as telephone optical transceivers and PCM equipment. It must rely on optical cable communication and is not suitable for use under complex terrain conditions. The second type is wireless transmission equipment. This type of equipment is mainly based on multi-carrier modulation wireless transmission equipment based on the IP system. At present, such equipment cannot directly connect to analog telephone lines, and cannot realize the distribution of extension numbers at the central office. At the same time, most wireless transmission equipment is point-to-point or point-to-multipoint, with poor mobility and weak anti-interference ability, which needs to be improved.
