On January 15, the Civil Aviation Administration of China issued the "Guidelines for the Assessment of the Use of Portable Electronic Devices (PEDs) on Aircrafts" stating that onboard PEDs (laptops, tablets, e-books, mobile phones, video players and electronic games Machine) conditions for use are basically mature.
Since January 17, major airlines have announced that they will allow the use of mobile phones on board. Passengers only need to turn on the flight mode of their mobile phones. Many netizens joked that "airplane mode finally comes in handy."
Airplane mode refers to a device that can turn off the sending and receiving of cellular mobile signals by mobile phones to prevent mobile phone signals from interfering with aircraft flight. As airplane mode gradually comes in handy, there is controversy over who invented it.
At noon on January 18, Qualcomm China (Qualcomm China) posted on Weibo that Qualcomm obtained the patent for "Airplane Mode" in February 2000, adding that although it could be used when cellular connections were disabled at the time There are very few mobile phone applications, but it is believed that this invention will be widely used as mobile phone functions become more complete.
However, Qualcomm was "slapped in the face" that night. Huawei said that the patent was its own. He Gang, president of Huawei's terminal mobile phone product line, posted on Weibo that "Huawei has a relevant patent granted by the China Patent Office for turning off the wireless function of mobile phones, and has posted a patent certificate and patent description.
