Introduction to wireless USB applications-home

The previous article introduced wireless USB applications in enterprises. This article describes wireless USB applications in the home network. In the home network, wireless USB applications tend to be more user-friendly and entertaining products. It brings more colors to people's lives.

Wireless USB applications in home networks

Consumer electronic products used by modern homes, such as digital audio and video devices, video devices, portable computers, PDAs, MP3 players, and high-definition image display devices, are evolving towards lightweight, portable, and mobile devices, these devices with strong multimedia functions, camera functions, display functions, printing functions, and playback functions can achieve convenient and fast interconnection through a home network built based on wireless USB technology, this provides more powerful home entertainment services.

It should be pointed out that consumer electronic products have high performance requirements, especially for the transmission rate of streaming media with large data volumes. Take playback of DVDs on high-definition color TVs as an example, to meet the basic playback requirements, the data transmission rate required by the DVD must reach 3 ~ 7 Mbit/s, HD color TV needs 19 ~ 24 Mbit/s, while wireless USB can provide up to 480 Mbit/s of transmission bandwidth, fully meeting the bandwidth needs of home entertainment.

Using a new wired USB standard USB on-the-go design concept, wireless USB defines a new device type with dual identities: dual-role. This device provides both USB host and USB device functions. It can be used as a USB device, connected to a USB host, or act as a USB host to connect to other USB devices.

Wireless USB applications for this product

1) digital cameras and printers.

Originally, they can only act as digital cameras and printers for USB devices. Data Transmission and printing services between the two can be completed through the USB Host relay, Which is inefficient and cumbersome. The digital camera now has the dual functions of USB host and device, you can establish a wireless USB connection directly with the printer as a USB device as the identity of the USB host, data transmission and printing of images are convenient and quick.

2) MP3 player and wireless speaker.

With dual-function MP3 players, you can establish Wireless USB connections with nearby wireless speakers to maximize the convenience and mobility of MP3 players, you can also enjoy the perfect music from high-quality and surround-sound devices.

3) digital cameras and DVD recorders.

After the dual functions are added, a digital camera can establish a wireless USB connection with a DVD recorder acting as a USB host, this allows you to conveniently and quickly download the Real-Time captured image information to a DVD recorder to complete the burning of important image data on a DVD disc.

4) PC and mobile phone.

As a USB host, the PC establishes a wireless USB connection with the mobile phone that acts as a USB device, for example, calendar, contact information, music, and images can all be transmitted to mobile phones through wireless links to achieve resource sharing and utilization.

5) image storage devices and video playback devices.

Image files that can be played for several hours on the image storage device can be connected via wireless USB and transmitted to the image playback device within a few minutes. On the way to and from work, work is idle, take a break at noon, and wait for a car, you can enable the video play device at any time to watch the news, movies, and sports events downloaded.

6) PDA and large-capacity storage devices.

PDA usually stores important information, such as phone numbers, E-mail, diaries, work logs, notes, and various work documents. You can connect to some large-capacity storage devices through wireless USB, for example, a DVD recorder or Flash longu disk can download and save important information.

This article briefly introduces the wireless USB application in the home network. It is foreseeable that, with the completion of technical standards, it has been vigorously promoted by leading companies such as Intel and Microsoft, wireless USB technology will be rapidly applied and developed in many fields such as computer, consumer electronics, mobile communication, and industrial automation control.
