DESCRIPTION
Wireless communications is being rapidly implemented in the industrial environment, with great success, provided certain ground rules are applied. These include ensuring a robust wireless link, correct integration with the wired communications systems, and proper data security. The critical objective of wireless communications networks must be to achieve similar capacities, bandwidths, responsiveness and availability to that of wire-based communications systems. Apart from covering wireless basics, the workshop provides an in-depth coverage of the main industrial wireless technologies in use today, viz. radio modems, IEEE 802.11 wireless LANs (Wi-Fi) and IEEE 802.15.4 wireless PAN technology as implemented by a multitude of process control system vendors. WirelessHART is a specific example of this. The workshop also covers some of the secondary technologies that are not known as industrial technologies per se, but which still find widespread application in industrial environments. These include Bluetooth, LP radio, mobile (cellular) data systems and VSAT. At the end of the course you should have a clear understanding of the choices available to you in designing and implementing your own industrial wireless network.

Introduction
Useful in Supervisory Control and Data Acquisition (SCADA) systems
• Wireless point-to point systems:
IEEE 802.11 used more as a wireless extension to Ethernet in a plant environment & for mesh networks
IEEE 802.15.4 - Easy to use, reliability and redundancy
• SP-100 Wireless Systems:
Establishing standards, recommended practices, technical reports, and related information to define procedures for implementing wireless systems in the automation and control environment

Ethernet • Dominant LAN technology
• Provides a set of physical media definitions, a scheme for sharing that physical media (CSMA/CD or full-duplex), and a simple frame format and hardware source/destination addressing scheme (MAC addresses) for moving packets of data between devices on a LAN
• Limitations - Support one or more communication protocols

TCP/IP
• Provide routing services, end-to-end verification of transmitted data, and interfacing services to the stack for clients and servers
• Ensures correct delivery of data, and sliding windows to prevent data buffer overruns on the receiving side
• A connection-oriented transport protocol
• A very reliable protocol
