Line of sight (LOS) or near line of sight often plays an important role in radio coverage for example for broadband fixed wireless access systems (BFWA) operating at high frequencies in urban areas. For coverage prediction and cell planning, complex ray tracing calculations based on detailed 3-D building information are usually necessary. In this article, a simple model is presented that directly...
Line-of-sight (LOS) is often required in fixed broadband wireless access systems like LMDS or WiMAX. However, the percentage of customers in a cell which can be reached via a LOS link depends strongly on the environment and other scenario parameters. In this article the influence of these parameters on an introduced average LOS coverage ratio is analyzed using ray tracing calculations and approximately...
