An accurate and effective physical layer simulator for micro- and pico-cellular radio systems and networks

Complex multipath and interference effects have become the important system design and planning considerations in micro- and pico-cellular broadband mobile data networks such as wireless LAN (WLAN) and very short range personal area networks (PAN) like those based on Bluetooth. Another important issue is the interoperability and coexistence of these various network technologies. Bluetooth and IEEE 802.11b use the same portion of radio spectrum (2.4 GHz) and are liable to interfere. Most of the recent propagation models are based on simple statistical path loss algorithms, which become very inaccurate in the complex indoor environment. The deals with an accurate indoor end-to-end physical layer (radio channel) model including the radiowave propagation environment, antenna model, and the RF/IF front end circuit and baseband processes. The simulator´s interface geometrical modeler makes the tool very convenient for complex environments. Results are shown indoor propagation effects for short-range technologies interfering on each other in a simple common RF link.
