As the need for additional process measurements increases, users seek a simple, reliable, secure and cost-effective method to deliver new measurement values to control systems without the need to run more wires. With process improvements, plant expansions, regulatory requirements and safety levels demands for additional measurements, users are looking to wireless technology for that solution[1].

With approximately 30 million HART devices installed and in service worldwide, HART technology is the most widely used field communication protocol for intelligent process instrumentation. With the additional capability of wireless communication, the legacy of benefits this powerful technology provides continues to deliver the operational insight users need to remain competitive[1].
