Method for 315/433 MHz Remote Keyless Entry sensitivity and range statistical analysis for automotive applications

The paper describes methodology for modelling and simulative estimation of sensitivity and range of ISM band Remote Keyless Entry transmitter-receiver system for automotive applications. The method is based on electrical simulation including PCB extraction data and parameters statistical distribution to evaluate best- and worst case scenarios. Both transmitter and receiver circuits are considered, as well as link environmental conditions. Examples of results are given for presented methodology.
