Wireless automation for process control

摘要

Several different wireless technologies have evolved to support flexible links for industrial networking and process control applications, with a range of capabilities. Heiko Luckhaupt of RS Components explains. There is a range of unlicensed frequencies available, varying from the sub-1GHz variants in different parts of the world to the unified 2.4GHz band. This provides greater volume, lower costs and more opportunities for integration of the RF transceiver with a low cost microcontroller core.
