Dual wireless communication device

Abstract

The invention provides a dual wireless communication device. The dual wireless communication device comprises a first antenna, a second antenna, a first wireless communication module, a second wireless communication module, a processor and an isolating circuit for isolating the first antenna from the second antenna. The first wireless communication module is electrically connected to the first antenna and used for generating a first radiation signal, while the second wireless communication module is electrically connected to the second antenna and used for generating a second radiation signal. The isolating circuit comprises a coupling unit, a phase adjustment unit, an adjustable attenuation unit, and is used for performing phase adjustment and signal attenuation on the first radiation signal and the second radiation signal. The processor is electrically connected to the first wireless communication module, the second wireless communication module and the adjustable attenuation unit, and used for calculating the isolation degree of the first antenna and the second antenna and comparing the calculated value with a preset value so as to adjust the attenuation degree of the adjustable attenuation unit according to a comparison result. The dual wireless communication device is capable of increasing the isolation degree between two antennas and preventing the same frequency interference generated by the dual wireless communication device.

Description

technical field [0001] The present invention relates to a dual system coexistence device, in particular to a dual wireless communication device. Background technique [0002] With the rapid development of the communication field, there are more and more dual wireless communication devices, such as dual IEEE802.11 routers. However, the throughput of this dual wireless communication device will be reduced due to the same-frequency interference generated by the two wireless signals, especially when the two wireless signals are in adjacent channels, the impact on the throughput will be greater, so it is necessary to Improve the isolation of the two antennas to prevent interference. Usually, the isolation can be increased by increasing the physical distance between the two antennas, but the space of the equipment is limited, and the increase cannot prevent interference well. Therefore, being able to effectively prevent co-channel interference generated by dual wireless communic...
