The main purpose of this project is to start in design a trusted source network simulator called (RadioEng Simulator). RadioEng version 1.0 is an elementary version used to simulate a part of wireless mobile networks physical layer for the most famous propagation models. This version is based on MatLab package. This version focus on mobile networks that works by GSM, DCS, UMTS, WiMAX, and LTE technologies. The propagation models supported in these technologies are Free Space Path Loss (FSPL) model , Okumura model, Hata model, COST 231 model, SUI model and Walfish-Ikegami model. The simulator results are verified by other network simulators.
