Home wireless network technology application details

Wireless network technology is widely used, and people have higher requirements for intelligence. So I studied the practical application of home wireless network technology and shared it with you here, I hope it will be useful to you. Generally, the realization of entertainment functions in the home, such as television, DVD, and audio, is basically concentrated in the living room, the PCs and networks that carry the information acquisition and exchange functions mainly exist in the study. With the emergence and mutual penetration of various portable entertainment and information exchange products, the demands for entertainment and information exchange functions are everywhere in the family: anywhere in the family, the bedroom, living room, kitchen, bathroom, bathroom, and even storage room all require free entertainment and Internet access, rather than confined to the living room and study room. The Application of Various wireless network technologies in the home can enable the computers and various household appliances in the home to be connected without complicated cables. This gives us more freedom, simplicity, and convenience.

Home wireless network technical requirements

Wireless LAN (WLAN) technologies and products based on 802.11x wireless network technology are now widely used within the company and in public. Most of the currently available wireless network technology products are also based on 802.11x wireless technology. But in fact, the technical requirements of home wireless networks are different from those of public wireless networks, which are embodied in the following aspects.

L. data transmission bandwidth

In home applications, digital multimedia applications account for an important proportion. For example, you can use a digital display device (such as an LCD TV) to watch a DVD or high definition MPEG2 Video Stream stored on a media adapter, use an MP3 player to play and store MP3 audio streams on a PC at home. Therefore, the home wireless network must have a bandwidth that supports the transmission of multiple digital videos/audios. We know that digital display devices (plasma TVs or screen projection devices), PDAs, and MP3 players generally use several hundred Kbps (for example, MP3 audio streams can reach 320 Kbps) to dozens of Mbps (for example, 1 OMbps for a DVD Video Stream and 2.5 Mbps for a high-definition MPEG2 Video Stream ). It is essential to add wireless network functions to digital entertainment devices and provide sufficient bandwidth for data transmission.

2. Low Price

According to a survey, to allow a household device to add wireless connection functions, users are usually only willing to spend 5% to 10% more, which is a great test for related product manufacturers.

3. Dynamic Network Configuration

A flexible and dynamic network configuration is also very important for home users. In the home wireless network technology, the number of wireless application devices and the Space Range of network applications vary with different families. Therefore, a flexible network structure must be applied. The "mesh" network architecture allows each device in the network to act as an access point in the network, allowing each application device to act as a bridge to connect to other devices, allowing users to gain a wider range of wireless application space. Even when necessary, some low-price bridging devices can be fixed on the walls of the room, through which we can connect farther distances. The "mesh" wireless network architecture provides greater network access performance and larger Application Space coverage, which ensures that more devices in the home can access the home wireless network.

At present, it is easy to add an external box with wireless functions on the home digital device to implement the wireless application function of the product, but this is only a simple transitional approach. With the development of home wireless network technology and products, the wireless function module will eventually be integrated into the product in the form of a wireless network function chip, to achieve the hardware and integration of the product's wireless function. The prospect of home broadband wireless connection applications is exciting, and the industry has invested a lot of attention in this regard. We must realize that the home broadband wireless network not only requires high data transmission speed, but also users are more sensitive to product prices, while minimizing the power consumption of devices. As home broadband wireless networks are emerging wireless applications, wireless technologies that meet the needs of the home market are still being explored.
