Abstract
(EN) PURPOSE: A physical layer configuration method of low side wireless telecommunication is provided to increase the performance of communication by applying a packet format and a coding/ modulation system between a master and slave. CONSTITUTION: The communications frame comprises a preamble, a header and a payload. The header field comprises 3-bit data rate and coding information area, 8-bit payload data length area of 5 bit reserved area and 8-bit header check sequence. The header check sequence comprises 8-bit cyclic redundancy check. The payload field comprises data area with the maximum 255 byte and 2-byte frame check sequence. COPYRIGHT KIPO 2010
