HD network set-top box dual-band WIFI is what? what is the benefit?

HD network set-top box, in addition to its emphasis on video resolution, it also emphasizes the stability of the network environment, even if a box has a wealth of video resources, there is no stable, fast network transmission speed, watching video is not a happy thing, On the contrary, it will be very painful. The screen will pause from time to time, afterimages. In response to this demand, set-top box manufacturers have launched products that support dual-band WIFI, such as Haimeidi M3 and Taijie webox.

What is dual-band WIFI?

The so-called dual-band WIFI refers to the wireless signals that support two different frequency bands at the same time. The two network segments are 2.4G and 5G, and support 802.11a/b/g/n technology. It is a fifth-generation WIFI transmission technology.

At present, most wireless products use single-band 2.4G WIFI wireless transmission, such as wireless mouse, keyboard, USB wireless network card, ordinary wireless router and so on. Some higher-end smart devices support dual-band WIFI technology.

Low-interference 5GHz wireless network, with built-in QoS features and security encryption mechanism allows you to easily high-speed Internet access, receive chat, HD high-definition network video viewing, online game play and share music and photos.

Dual-band WIFI advantages and disadvantages

1, 2.4G band wireless signal advantages and disadvantages. The advantage of 2.4G is that the ability to penetrate the wall is good, and the disadvantage is that it is vulnerable to interference.

2, 5G band wireless signal advantages and disadvantages. 5G has the advantages of strong anti-interference ability, wide bandwidth, high throughput, and strong scalability. The disadvantage is that 5G is only suitable for indoor small-scale coverage and outdoor bridges, and various obstacles have a greater attenuation effect than 2.4G. many.

5G WIFI has increased four times faster than the existing wireless bandwidth, the bandwidth can be increased to 40MHz or even 80MHz or higher, the transmission speed is up to 1Gbps, and the content of about 125MB can be transmitted per second, and the next movie can be solved in a few minutes.

What are the benefits of dual-band WIFI set-top boxes?

1. Single-frequency WIFI network High-definition set-top box Compared with the dual-frequency set-top box, it has stronger and more stable WIFI wireless signals and higher-speed transmission speed, which can meet the future HD and big data wireless transmission needs.

2. It is possible to use the box remotely. For example, a wireless router is placed in the living room, and we need to use a box in the bedroom. A set-top box with dual-band WIFI function will protect you and ensure the stability of video playback and smooth operation.
