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.

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



Example setup


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
