A few days on the front opening of the exhibition MWC Shanghai, OPPO demonstrated a wonder that the author of Black & - "No network communication technology" that cellphone without a WiFi, Bluetooth, and mobile networks, the still voice and exchange text. More importantly, in the open outdoor or urban environment, the effective transmission of information up to 3 km from the farthest.
Although the OPPO did not detail the technical principles and related product model, but according to industry speculation, the technology has the potential uses digital private network information technology on business-like digital radio, by encrypting the channel, point to point, end end of communication.
When I heard the news, the first reaction is: Is not that Mobile, China Unicom, walkie-talkie advanced upgrade version? Could it be that Mobile, China Unicom, walkie-talkie to be cool? Reflect on down, it should not be.
OPPO According to official reports, "no network communication technology" is achieved through free networking between multiple devices. But this means that multiple devices What equipment? The same equipment OPPO this brand? Or other brands of mobile terminals can be? Or communication base stations can be? If you do not OPPO brand of mobile phones, users can use this technique and it at the crucial moment?
In my opinion, "no network communication technology" point-to-end communication is very commendable. The technology has a wealth of opportunity in the extreme environment applications, emergency communications or part of the special outdoor environment operations. Just think, with such a mobile phone terminal, but also in times of emergency when the walkie-talkie phone use, how convenient! But if the technology can not communicate between different mobile phone brands, its use will be greatly reduced.
Another thing I admire OPPO is also customized communication chipset supports spread spectrum modulation and demodulation techniques. In the case of "no network communication technology," when the phone turns itself off, the remaining battery capacity to continue monitoring the channel can support up to 72 hours may be sent off before the last recorded GPS positioning is found in the other device. If you encounter a crisis, timely access to the final location of the incident, and that the 72-hour rescue efficiency of gold recovery will also be more efficient.
Overall, the "no network communication technology," If we can carry on popularization, will have a very wide range of application scenarios. It is noteworthy that, if the full sense of presence to promote this technology, walkie-talkie, will certainly be further weakened. But only through a free networking between multiple devices wanted to "get rid of" China Mobile and Unicom may still be difficult to achieve. After all, technology just released, specifically how to develop our line and let me see!
