Wireless USB or will debut next year

Wireless USB applications are expected to take shape in 2014. With the advent of version 3.1, the Universal Serial Bus (USB) transfer rate has reached 10Gbit/s. To achieve further breakthroughs in USB cable and connector specification limits, chipset vendors have begun to promote the use of wireless local area network (Wi-Fi) technology for transmission. Wireless USB technology for data is expected to start supporting next-generation mobile device processors next year.

The use of wireless means to connect the mobile device to all peripheral devices having a USB connector interface will improve the convenience of data transmission of the mobile device. Therefore, starting in 2014, mobile devices using Qualcomm’s next-generation Snapdragon processor will be able to achieve the use of USB over Wi-Fi for Wi-Fi technology.

It is reported that if consumers want to wirelessly transmit mobile device data to various USB devices, the USB host of the mobile device must first be wirelessly connected to a Wi-Fi Serial Bus (WSB) hub (Hub). ). The device then transmits the information in a wired manner to a display, mouse or other peripheral device.

However, as the USB connector ecosystem continues to improve, and most peripheral device manufacturers choose to have built-in Wi-Fi serial bus elements in their products, it will not be difficult to directly connect mobile devices and USB peripheral products wirelessly; Based on the Snapdragon's USBOverWi-Fi feature, which allows mobile devices to establish strong Wi-Fi links directly with existing USB peripheral devices, mobile device users no longer need to use the WSB hub to easily complete data transfer operations anywhere, anytime.

In addition, Snapdragon's USBOverWi-Fi feature also eliminates the need for a USB connector for mobile devices. For consumers and manufacturers, removing the miniUSB connector on a smartphone can be extremely beneficial.

It is worth mentioning that the SnapdragonUSBOverWi-Fi solution allows manufacturers to use the USB drivers provided by current operating system vendors, thus minimizing interoperability testing costs for various devices, such as audio/video systems and human-machine interface devices (HIDs). ) and large-capacity storage equipment, etc., will help manufacturers to increase their willingness to use.
