  • Patent number: 11870483
    Abstract: A smart antenna switching method is disclosed. Multiple wireless signal parameters of a wireless network environment are collected. Under a current operating phase, when a holding period of a to-be-switched antenna is 0, the qualities of wireless signals between an initial antenna and the to-be-switched antenna are compared according to the wireless signal parameters. When a comparing period of the to-be-switched antenna is 0, it is determined whether an antenna switching operation is performed. If the antenna switching operation is not performed, the next operating phase is served as the current operating phase. If the antenna switching operation is performed, a signal receiving-and-sending operating is switched from the to-be-switched antenna to the outdoor antenna or from the outdoor antenna to the to-be-switched antenna, and the previous operating phase is served as the current operating phase.

  • Publication number: 20230319501
    Abstract: A method for providing better connecting signals is disclosed. Coordinates of multiple mobile terminals are obtained. Distances between a mobile Wi-Fi (MIFI) device and the mobile terminals are calculated according to received signal strength indicator (RSSI) values between the mobile terminals and the MIFI device, and a relative coordinate of the MIFI device is then calculated based on the distances. Unit vectors of the mobile terminals relative to the MIFI device are calculated according to the relative coordinate of the MIFI device and the coordinates of the mobile devices. Reference signal receiving power (RSRP) values of the mobile terminals are calculated and are multiplied by the unit vectors to obtain RSRP vectors of the mobile terminals. The RSRP vectors are added up to generate a position where the MIFI device moves to a base station.
