Challenges of Wireless Communication in Industrial Systems

 The WirelessHART standard was initiated in early 2004 and developed by ABB, Emerson and others.  The underlying wireless technology is based on the TSMP technology from Dust Networks  In April 2010, WirelessHart was approved by the IEC, making it the first international standard for wireless in process automation, IEC 62591  In ABB, the WISA concept (Wireless Interface to Sensors and Actuators) was created in 1998  First WISA devices went into industrial production equipment in 2003 and the first series products were available in mid 2004.  WISA-COM the tailor made wireless communication solution for factory automation based on IEEE 802.15.1 (physical layer) and WISA-POWER, the unique wireless power supply solution.  Factory automation in many cases requires a response time of less than 10ms for a machine with more than 100 sensors and/or actuators.
