In the intelligent impact of color TV market, smart devices have gradually spread to people's lives. Among them, the network set-top box as an important form of existence and much loved by users. From the development to the present, set-top boxes have been gradually divided into two types: antenna (built-in antenna) and external antenna, which are divided into internal antennas represented by millet, box, Levision, Infinik I9, and Tianmin and Haimei. Di, Kai Boer and other external antennas represented. However, when choosing a set-top box, users of the camps have been arguing over the issue regarding the built-in antenna and the external antenna. So what is an external antenna or a built-in antenna?
The network set-top box or the built-in antenna is good, let's say it with a mobile phone. Which cell phone do you see with a WIFI antenna, unless the oldest big phone, the current smart phones are not all built-in antenna? WIFI signal is also very good ah, network set-top box is also an intelligent system, and the phone is not the same principle!
Anti-side: external antenna is good
Knowing the signal should know that there is a gain concept. The higher the gain of the antenna, the better and the more stable the signal. A set-top box with an antenna is generally a 3dB gain antenna, and the signal is definitely better than the built-in antenna!
Which set of built-in antenna and external antenna in the network set-top box is better?
The network set-top box now generally uses the RTL 8188ETV this WIFI chip, built-in external use it, this chip supports up to 150M. In fact, the network set-top boxes all have antennas, and the set-top boxes with built-in antennas also have antennas. This WIFI antenna, this REL8188 chip comes with two antenna contacts, the general manufacturers will receive the antenna to this contact, many domestic cottage manufacturers are their own hand-welding, if the quality is not off, in the process of bumping Or it is easy to use the process of welding or welding off, then the set-top box's WIFI ability to accept it is not good! Many online reports of unstable WIFI links are mostly for this reason.
Is that better than the built-in antenna? In fact, it cannot be said exactly. Set-top boxes with built-in antennas also have a number of disadvantages. The built-in antenna is generally an antenna contact that is soldered to the WIFI chip on the bottom line. Then, the WIFI instability may also occur.
The set-top box WIFI signal of the built-in antenna and the external antenna is basically indistinguishable. If the set-top box signal of eight antennas from 100M is not good enough. The signal quality of the network set-top box is actually very much related to the router. If the routing is relatively stable, the WIFI of the set-top box is stable, but the set-top box of the built-in antenna does look good. Users can feel like they choose to bring their own without antenna.
Xiao Bian summary
In fact, the network set-top boxes are all equipped with antennas, but the structural design is different. Some set-top boxes have built-in antennas for better overall aesthetics, while others have chosen external antennas for better signal transmission and reception. For our average family, the two do not differ greatly in the basic signals. The important thing is whether the set-top box's work is fine, because the rough work not only affects the appearance and practicality, but it will affect the wireless signal whether it is built-in external antenna or not. Therefore, when you buy a network set-top box, you should pay attention to the selection of brand models to purchase. To ensure the practicality of work materials.
Square: built-in antenna is good
Technology is constantly improving. You can see whether all the electronic products around you are designed with flawless lines, such as phones, pads, other brands of mobile phones, notebooks, and similar products such as Apple V, millet boxes and other electronic products. Why these products have eliminated the design of external twist lines? Mainly because the strength of WIFI receiving capacity depends on the quality and technology of the WIFI module, and it has nothing to do with whether it is external. The network set-top box or the built-in antenna is good, let's say it with a mobile phone. Which cell phone do you see with a WIFI antenna, unless the oldest big phone, the current smart phones are not all built-in antenna?
