Title: Francis John Rowsell: Innovator in Radiocommunications Technology
Introduction
Francis John Rowsell is a notable inventor based in Felixstowe, GB. He has made significant contributions to the field of radiocommunications, holding a total of 2 patents. His work focuses on improving data collection systems through innovative technologies.
Latest Patents
One of his latest patents is a multipoint to point radiocommunications network. This system involves a number of remote terminals (RT) that transmit data packets for reception by one or more fixed data collectors (FDC) or a portable data collector (PDC). Each remote terminal transmits data in two frequency sub-bands, which are tuned to the respective fixed and portable data collectors. The channel capacity is enhanced in the fixed data collector sub-band by employing minimum shift keying (MSK) encoding and a pseudo-random variation of frequency error applied to the packet transmission frequency for successive packets. The fixed data collectors utilize dual fast-Fourier transform signal processing to interpret simultaneous packets with different error frequencies. This innovative design simplifies system setup and provides coverage in areas where a fixed data collector network has not yet been established. The system is particularly useful for monitoring devices such as gas and electricity meters and security systems.
