This is no joke. Everyone knows that the 5G network is faster, wider in bandwidth and less in delay. In order to realize these characteristics, in addition to the way of fixed-point signal transmission, high-frequency communication technology is also essential.
The frequency band under 4G network is 2-3GHz, but at 5G, the low frequency band overlaps with 4G network, but the high frequency band can reach between 25 GHz and 52.6 GHz. Under such a high frequency signal, the "dielectric constant" of the material is very high.
The following is Baidu Encyclopedia's explanation of "dielectric constant". It doesn't matter if you don't understand, and neither does Xiao Mo.
To put it bluntly, the dielectric constant is very important to the high frequency communication technology of 5G network. If the dielectric constant of the material used in the mobile phone case is too high, the transmission speed under the 5G network will slow down, resulting in signal disconnection or delay, which is what we often say. The signal is not good
It is said that a material with high dielectric constant, metal, can also be used as a metal protective shell in the 3G era, but it has almost disappeared now. In the 5G era, it is more difficult to see the metal mobile phone case. At present, the most common materials are TPU and TPE, especially the mobile phone case made of TPE is likely to become the mainstream under the 5G network.
What are the characteristics of TPE?
The full name of TPE is "thermoplastic elastomer", which is an artificial rubber. It is more environmentally friendly and has excellent plasticity. The most important thing is that its dielectric constant is very low, which is very suitable as a mobile phone case under 5G network.
At present, the most common mobile phone cases compatible with 5G signals on the market are mostly made of TPE. Is this environmentally friendly, feels good, and does not affect the signal perfection?
Of course not. The heat resistance of traditional TPE material is not as good as that of ordinary rubber, and it is easy to yellow in high temperature environment for a long time. As an object that is often held in your hand, you should not only pursue functionality, but also be very important. Is there a better solution in the 5G era?
Mophie series D3O anti-fall protective sleeve is compatible with 5G signals.
Of course, PC is also made of low dielectric material. At present, the original back covers of many 5G mobile phones are composite plates of PC and PMMA, which will not affect the signal and will not be yellow easily.
Mophie uses PC composite material in the back panel of mobile phone case series compatible with 5G signals. The crystal clear series protective case has a crystal clear texture, which perfectly shows the original back case of iPhone.
Of course, more than that, mophie also added a patented technology-the use of D3O material on the mobile phone case. This brand-new material can effectively absorb external impact. mophie's mobile phone case is made of D3O material. This series of mobile phone cases can protect the height of 3m~4m, which is the real protection.
In addition to the application of new materials, a brand-new anti-printing and dyeing technology has been added, which is much more durable than the most common TPE, and the mobile phone case of mophie crystal series can also be kept fresh.
Mophie not only has the traditional crystal series, but also has a protective shell compatible with magsafe magnetic attraction. For users who are "spoiled" by magsafe magnetic charging, it is easier to aim the charger at this protective case, which is more attractive.
The new material D3O, the safest protection, the most reliable anti-fall scheme and the best wireless magnetic charging partner are still used around the mobile phone case.
With the development of 5G network, while improving the online experience, the choice of mobile phone case should not be sloppy. Mophie's new series of mobile phone cases are not only resistant to falling, but also compatible with 5G signals. While the functions are complete, the face value and personality can't be lost. In addition to the crystal series, mophie also introduced many different designs of mobile phone cases. Interested students can click on the link below to learn.
