Wireless internet access card

Abstract

The invention discloses a wireless internet access card, and relates to wireless communication technology. The wireless internet access card provided by the embodiment of the invention comprises a base band, a wireless internet access control unit arranged in the base band and used for modulating the demodulation, a radio frequency nest plate connected with the wireless internet access control unit and used for frequency band conversion, an antenna connected with the radio frequency nest plate and used for sending and receiving a wireless signal, a USB interface used for connecting a PC, a storage unit, a power amplifier unit, a code unit, a microphone interface, a recording control unit, and a recording unit. Therefore, the functions of amplifying audio signals, coding audio files, and generating, storing and managing the audio files are realized in the wireless internet access card, the wireless internet access card can record sound, processing resources in the wireless internet access card are fully utilized, and the requirement that a user performs sound recording at any time is met while the wireless internet access card is used to surf the internet.

Description

technical field [0001] The invention relates to wireless communication technology, in particular to a wireless network card in the wireless communication technology. Background technique [0002] With the maturity of 3G technology, the data carrying capacity of the wireless network is getting stronger and stronger. Wireless Internet access has become a trend, and wireless network cards used for wireless Internet access have also entered people's lives. [0003] The current wireless network card includes a baseband, a radio frequency chip connected to the baseband, an antenna connected to the radio frequency chip and a USB interface connected to the baseband. When in use, the wireless network card is connected to the PC through the USB interface. When the computer receives data from the 3G network, the wireless network card receives the wireless signal in the 3G network through the antenna, and converts the received wireless signal from the frequency band signal to the baseb...

AI Technical Summary

Problems solved by technology

[0004] The inventors of the present invention found that the baseband processing speed and control ability of the wireless network card are relatively strong. When the wireless network card is not used to access the Internet, the baseband of the wireless network card is in an idle state, which wastes the processing resources of the wireless network card. When users need to record, they need another recording device, which is very inconvenient.
