1. A method for optimizing a bitrate of a wireless hotspot device in a mobile network having a plurality of distributed cells, each cell covered by at least one fixed transceiver, the wireless hotspot device having at least one directional antenna, the method comprising the steps of:
a) rotating the directional antenna substantially azimuthally at least 90 degrees, in steps of N degrees, wherein N is a fixed or variable number;
b) scanning for available cells for each step of N degrees the directional antenna is rotated;
c) observing a signal to noise ratio for each available cell in each step of N degrees;
d) saving an optimized azimuthal direction for each available cell, wherein the optimized azimuthal direction corresponds to the highest signal to noise ratio obtained for the available cell;
e) repeating steps a)-d) for a number of frequency bands of the mobile network,
f) setting up a data connection and running a data transfer speed test for all optimized azimuthal directions of each frequency band;
g) automatically selecting an azimuthal operation position of the directional antenna based on the data transfer speed tests; and
h) moving the directional antenna to the azimuthal operation position,
wherein the directional antenna is rotated in steps of 1-20 degrees, or in steps of 5-15 degrees, or 5 degrees or 10 degrees.
