Practical investigation of building penetration loss in Tripoli area

The measurement and analysis of penetration loss into building plays an important role in calculating the indoor coverage in wireless communication networks. In order to get an empirical model for this loss, several measurements of BPL in different areas in the Libyan capital; Tripoli were undertaken. Actually, this work is the first real measurement of BPL in Libyan environment, and it is expected to be very helpful in planning and dimensioning wireless mobile network in this region. These measurements were taken for four different types of wireless communication networks, two of them are categorized as long range networks namely; Mobile Telephone Network (for Almadar company), which operates at 900 MHz and WiMAX network (for Libyan Telecom and Technology LTT company) which operates at 2500 MHz, the other two are categorized as the short range networks (Wi-Fi and Bluetooth) operate at 2.4GHz. The results for each network were summarized, discussed and presented in tables and several graphs.
