There are many discussions about the death grip of metal mobile phones on the Internet. Especially when holding, if there is only one antenna below, it will easily lead to poor antenna performance. According to this theory, when P8 makes a phone call, the signal of the upper antenna may be bad due to the head, and the signal of the lower antenna may be bad due to the hand holding. In the case of poor signal of the existing network, the signals of both antennas may be bad, and the problem of dropped calls will occur at this time (don't worry, dropped calls can only be dropped when the coverage of the network itself is very poor, otherwise Huawei mobile phones would have rolled out of the market).
but we noticed that when we hold the lower part of the mobile phone, we don't hold the lower part of the mobile phone completely. Generally, the left hand may be more likely to hold the bottom left of the mobile phone, and the right hand is more likely to hold the bottom right. So in order to solve this problem, Huawei launched the industry's first mobile phone P9 with three antennas technology.
When the network signal is bad, if the right antenna is affected by the right phone call, the signal of the upper antenna is not optimal because of the head. At this time, if the left antenna with the best signal can be intelligently selected, won't the problem of dropped call be solved? In this way, whether you are an ordinary right-handed or left-handed, the mobile phone can switch intelligently among the three antennas, and the signal will naturally be good.
generally, the performance of three antennas can only be reflected when the network signal is not good, but it is also when the network signal is not good that we have requirements for the performance of mobile phones. Therefore, the three-antenna technology pioneered by Huawei is a good solution to the weak signal in the network.
