Based on the cosine theorem, for any triangle, the square of any side is equal to the sum of the squares of the other two sides minus twice the cosine of the angle between the two sides and them, and the formula can be given as follows:
θ＝(cos-1(cosθ)*180/π)

Furthermore, other intelligent devices may also use two UWB intelligent modules as their base stations, and the two UWB intelligent modules need to be separated from each other in terms of structural design, so that a triangle is formed with the tag device described below, that is, the smart phone with the UWB module, and a relevant included angle is calculated, thereby determining the orientation of the intelligent device. The smart phone with the UWB module is used as a label, and identification information (specified as device type information) of the smart device installed in the base station can be obtained in the process of distance measurement and angle measurement between a transmitting signal and the two UWB intelligent modules used as base stations.
