Abstract: The present disclosure relates to a directional wireless hotspot device for communication in a mobile network having a number of distributed cells, each cell covered by at least one fixed transceiver, the device comprising: a printed circuit board; a directional antenna; a compass, such as a magnetometer; a geographical positioning device, such as a GPS receiver; an electric motor, such as a substantially flat piezoelectric motor, for rotating the printed circuit board around an axis substantially perpendicular to the directional antenna; a wireless modem, such as a 3G/4G/LTE/5G modem, or a receiving element, such as a socket, arranged to receive an external wireless modem; a local communication element, such as a Wi-Fi circuit, for communication with a local device; a microprocessor configured to calculate an azimuthal rotation angle for pointing the directional antenna to one of the fixed transceivers based on: directional and positional data from the compass and geographical positioning device; positional

Abstract: The present disclosure relates to an antenna device for a vehicle for optimizing the signal strength or quality from a mobile network having at least one fixed transceiver. The device comprises: at least one directional antenna; at least one turning device, such as an electric motor, for rotating the directional antenna around an axis substantially perpendicular to the antenna boresight; and a microprocessor configured to calculate an azimuthal rotation angle for pointing the directional antenna to at least one selected fixed transceiver. The calculated azimuthal rotational angle is based on: directional and positional data of the vehicle; positional data of the selected fixed transceivers; and a route for navigating the vehicle between a starting point and a destination. The azimuthal rotation angle of the directional antenna is calculated continuously or at intervals, such that the signal strength or quality from the mobile network is continuously optimized along the route.
