Abstract

The present invention relates to a wireless communication apparatus and a wireless transmission method working at dual bands. The wireless communication apparatus comprises a duplexer, a microcontroller, a first band signal processing circuit and a second band signal processing circuit. The duplexer performs frequency division on a received wireless signal to obtain a first wireless signal of a first band and a second wireless signal of a second band; the first band signal processing circuit and the second band signal processing circuit respectively process the first wireless signal and the second wireless signal, so that the wireless communication apparatus can perform uplink / downlink transmission on the first band and the second band; when downlink transmission is performed, the microcontroller monitors a first bit error rate for first wireless signal processing and a second bit error rate for second wireless signal processing; and when the first bit error rate is greater than a given value, the microcontroller lowers a working priority of a first wireless router, and stops downlink transmission with the first wireless router temporarily. Through adoption of the wireless communication apparatus and wireless transmission method, full timeslot uplink / downlink transmission is realized, the transmission rate of Wi-Fi is improved, and network connection of the wireless router is ensured to be stable.

Description

technical field [0001] The present invention relates to a wireless communication device and a wireless transmission method that work in dual frequency bands, in particular to a wireless communication device and a wireless transmission method that simultaneously perform uplink / downlink transmission in dual frequency bands. Background technique [0002] Among existing handheld terminal devices, Wi-Fi transmission has become an indispensable communication function. At present, the Wi-Fi working frequency band of the handheld terminal device is 2.4GHz or 5GHz. For handheld terminal devices that comply with 802.11a / b / g / n specifications, the maximum transmission rate can reach 150Mbps / s in the 2.4GHz operating frequency band or 5GHz operating frequency band. However, currently, the Wi-Fi handheld terminal device is only connected to one Wi-Fi wireless router, and performs uplink / downlink transmission in a time division duplex (Time Division Duplexing, TDD) working mode. At this ...
