Wireless networks 27 Nov 2007 Presented by: Brad Elmer Trent Bytheway
Current State • Cell phones • Computers • Wi-Fi • Blue-tooth • Routers • RFID tags • Radios • Media players
Where wireless is used • RFID tags • Human implants • Passports • ID cards • Inventory • Package tracking • Library • Asset racking in real time • Automotive • Smart keys
What its used for • Wireless communication for motion automation offers contactless, maintenance-free data transmission. Proficient communication over Bluetooth demonstrates this utility in a new, automated cold-storage warehouse in the Netherlands.
What it’s used for • GSM modems provide an excellent way to implement network communications to remote locations. This case study illustrates both the potential offered by public network GSM for remote telemetry and the technical specification demanded of units in the field.
What it’s used for • Scalance W Access Points and HiPath Centralized Controller enable pickle firm to implement automated monitoring, paperless work orders, VoIP integration and more-leading to a four-month ROI. • The ability to monitor outdoor tanks, factory floor equipment and warehouse facilities from any computer attached to the network, saving about $100,000 in maintenance costs over three years and far more-at least $2 million-by reducing down time in manufacturing production lines.
Supporting technology • Computers • Routers • PLC’s • Security protocol • Receivers • Switches • Sensors/monitors
Primary vendors • Lucent Technologies • Cisco • Liksys • Zoom Technologies • Telxon Corporation • Nortel • 3Com
Costs • Installation of wirelessly connected assets is up to 10x cheaper than the wired alternative and offers much faster startups and accelerated profits. • Engineering costs are dramatically reduced as extensive surveys and planning are no longer required to route wire back to junction boxes or control rooms
Pitfalls • Battery life • Security • Interference • Weather • Walls • Other devices • Not truly wireless
Advantages • Flexibility • Want-to-know vs. critical to process • Easily expandable • Access from anywhere • Savings • 1/10 the cost of wired alternative • Faster transmissions
New developments • Safer and more secure • Stronger signals • Faster transmission times • Will become standard • But…. People do not understand it and are afraid to use it
Class problem • Where could we use wireless in the EAAL lab?
Summary • Used everywhere • Saves money • Becoming industry standard
