This paper reports on the benefits of the remote communication systems and presents two prototype systems for communication with microprocessor based machines and devices including household appliances. The wireless prototype version can also be used in remote and wireless programming of any device with a microprocessor or microcontroller.
It is a known fact that the researchers often become too embraced with technical breakthroughs and forget about communicating with the audience for whom the findings of their research is intended. To this end, initial emphasis is on the benefits of the systems, but later in the paper the technical merits of the research work are explained.
The prime aim of the project has been to develop the know-how for remote programming, control and up-dating of programs in microcontroller based devices using wired and wireless techniques.
An earlier wireless communication system using laser encapsulation techniques developed for a factory of the future site [1] was revisited with a view to incorporate the latest technologies where appropriate. The earlier system adopting Code Division Multi Access with a Pseudo Random Noise Spectrum (CDMA-PRNS) incorporating wideband Spread Spectrum (SS) using Hierarchical Genetic Algorithm (HGA) was found to provide a basis for establishing a working Wireless Local Area Network (WLAN) for many applications including in the manufacturing, where noise has been a problem for their use.
