Device and method for improving wireless transmission rate of mobile phone

The present invention relates to an apparatus and method for increasing the wireless transmission rate of a mobile phone.

At present, the Risc platform of 2G mobile phones mostly has only one Secure Digital Input/Output (SDIO) interface 12, as shown in Figure 1, usually the SDIO interface 12 is used to connect Secure Digital (SD) memory. Body 5, and the Wireless Fidelity 4 can only be connected to ARM (Advanced Risc Machines) 1 by a Serial Peripheral Interface (SPI) 11. The WiFi module 4 is a wireless local area network based on the IEEE 802.11b standard. Its biggest advantage is that the transmission speed is high, and its effective distance is also long, and it is also compatible with various existing 802.11 DSSS devices. The SPI interface 11 is composed of a clock chip, a data input chip, a data output chip and a smart chip. Usually, the theoretical value of the clock signal generated by the clock chip can only reach 13MHz at the earliest, so the data transmission rate can only reach 13Mbit/s (1.625Mbyte/s). The SDIO interface consists of a clock chip, four data input and output chips, and a control command chip. The clock signal generated by the clock chip can reach a theoretical value of up to 48 MHz, and the data transmission rate is calculated by four data input and output chips. The fastest is 192Mbit/s (24Mbyte/s).

According to the above clock signal transmission value, if the WiFi module 4 is only used by SPI When the face 11 is connected to the ARM 1, the SPI interface 11 cannot make the wireless transmission rate of the WiFi module 4 come into play.

In view of the above, the preferred embodiment of the present invention provides an apparatus and method for improving a wireless transmission rate of a mobile phone, which solves the problem that the traditional SPI interface cannot enable the WiFi module to fully utilize its wireless transmission rate.

A method for improving a wireless transmission rate of a mobile phone, the method comprising the steps of: (a) initializing a secure digital input/output interface after the mobile phone is powered on; (b) when the ARM monitors the user's connection setting operation, determining according to the connection setting operation Whether to switch between the secure digital input/output interface and the secure digital memory to connect the secure digital input/output interface to the WiFi module; and (c) when the WiFi module needs to be connected, the ARM controls the general-purpose input/output The controller controls the secure digital input/output switcher to switch to the WiFi module, so that the secure digital input/output interface is connected with the WiFi module to increase the wireless transmission rate of the mobile phone.

Compared with the prior art, the device and method for improving the wireless transmission rate of a mobile phone are controlled by a GPIO controller to switch the SDIO switch to connect the SDIO interface with the WiFi module, thereby solving the traditional WiFi module. Only through the SPI interface and ARM The transmission is performed, and the SPI interface cannot fully utilize the shortcomings of the transmission rate of the WiFi module, thereby greatly improving the wireless transmission rate of the mobile phone.

Referring to FIG. 2, it is a hardware architecture diagram of an apparatus for improving the wireless transmission rate of a mobile phone. The device includes an ARM 1, a Power Management Integrated Circuit (PMIC) 2 connected to the ARM 1, a Bluetooth 3 (Universal Asynchronous Receiver/Transmitter, UART) or a Pulse Modulator (Pulse Code). Modulation, PCM) is connected to ARM 1. The ARM 1 controls the switching of the Secure Digital Input/Output Switcher (SDIO Switcher) 6 by the General Purpose Input/Output (GPIO) controller 11 so that the SDIO interface 12 and the WiFi are respectively connected. The module 4 or the SD memory 5 is connected. Generally, the SDIO interface 12 is connected to the SD memory 5 by default. When the user wants to connect to the WiFi module 4, the user can connect to the WiFi module 4 through the mobile phone function table setting, and the ARM 1 monitors the operation of the connection setting. The SDIO switch 6 is controlled to be connected to the WiFi module 4 by the GPIO controller 11, so that the WiFi module 4 is connected to the ARM 1 via the SDIO interface 12.

Among them, PMIC 2 is used to ensure that ARM 1 can be used in the case of power-on and power supply interference and to ensure reliable operation. It can also turn off the corresponding power when ARM 1 is in sleep and other power-saving modes. Bluetooth 3 is a proxy for short-range wireless connectivity technology standards The essence of Bluetooth 3 is to establish a common open standard for radio air intermediaries and their control software.

Bluetooth 3 is mainly used for all kinds of data and voice equipment in the network, such as PC, notebook computer, printer, fax machine, digital camera, mobile phone, home appliances, etc., using wireless microwave to connect them into a piconet. Multiple piconets can also be interconnected to facilitate communication between various types of devices.

The GPIO controller 11 simplifies the expansion of the I/O port using an industry standard I ² C, SMBus ^TM or SPI ^TM interface. The GPIO controller provides additional control and monitoring when the microcontroller or chipset does not have enough I/O埠 or when the system requires remote serial communication or control.
