Abstract

An empirical indoor to outdoor propagation model has been improved based on empirical techniques. Improved model includes building structures such as number of walls, position of windows and the affect of frequency. Proposed model is valid for GSM 900, GSM 1800 and CDMA 2100. Theory and measurements are in tracking each other at CDMA2100 and GSM frequencies by at most 6dB deviation. Generated model can easily be used for outdoor coverage predictions and interference capability based on indoor antennas, especially at CDMA
