The 2008 ISA EXPO covered many hot topics, including security, process automation, safety, environmental and quality control, enterprise integration, and wireless networking. But far and away was the excitement about wireless technology and new products, with many companies displaying emerging wireless products at the exhibit, and wireless standards featured in many presentations throughout the week. WINA also held a wireless walking tour entitled "WINA Wireless Tech Tour - No Wires, No Hype" to educate attendees about the wide range of wireless products and concepts displayed at the event.
