During the mobile radio network planning (GSM, UMTS, WLAN), there is a natural need for an optimal base station positioning procedure. Good coverage at an acceptable level of network installation and maintaining costs, low interference and uniform interface load are the main requirements. In this paper we present an approach based on surrogate optimization algorithm for optimization of indoor radio...
Recently there is a growing interest in providing and improving radio coverage for mobile phones and WLANs inside buildings. The need of such coverage appears mainly in office buildings, shopping malls, train stations where the subscriber density is very high. The cost of cellular systems and also the one of indoor wireless systems depend highly on the number of base stations required to achieve the...

Effect of the rotation of antennas on the capacity of the multiple-input -multiple-output (MIMO) system is demonstrated by numerical simulation. Both the transmitter and the receiver consist of three central-fed electrical dipole antennas. The MIMO channel matrix is made by double bouncing scattering model. Simulation shows that the highest value of the capacity can be when the angle to axis Z is...
