During Computex Taipei, Qualcomm demonstrated LTE and Wi-Fi sharing antenna technology, mobile Wi-Fi signal can lift 1.6 times. We know that most phones on the LTE (ie 4G) and Wi-Fi are each required to use two antennas in order to increase the transmission rate, but the more the antenna design brings more difficulties.
4G download these phones with the two antennas send out data while it only took one, so Qualcomm do this thing: at baseband accurately grasp the slot, and the other antenna intelligent switching to Wi- Fi use.
Specifically, LTE in the 200 millisecond interval to send and receive data, LTE will use a second antenna, so often Wi-Fi can be enjoyed LTE a second antenna, thereby becoming the 2x2 Wi-Fi. And LTE signal better place, Wi-Fi power consumption is reduced the more.
It is worth mentioning that this software technology requires smart enough to constantly monitor the status of LTE, LTE and in real time to ensure that Wi-Fi shared antenna.
