Creating
an Internet of Things
The Internet connects computers to one another. What
the Auto-ID Center aims to do, in effect, is develop
a network that connects computers to objects - boxes
of laundry detergent, pairs of jeans, airplane engines.
We are not creating just the hardware (RIFD tags and
readers) or just the software to run the network. With
the help of our sponsors, we are developing everything
that is needed to create an "Internet of things,"
including affordable hardware, network software and
protocols, and languages for describing objects in ways
computers can understand. The system will be based on
existing standards. It will be open to anyone, and it
will be entirely free - just like the Internet.
Why
is this necessary?
Well, it's not, any more than the creating the Internet
was "necessary." But just as the Internet
has made companies vastly more efficient by enabling
them to share data, we believe that the ability to track
individual items as they move from factories to store
shelves to recycling facilities will make companies
vastly more efficient. Companies, in fact, have long
realized that capturing data about goods automatically
and accurately would be a great boon to their business.
Billions of dollars have been invested worldwide in
bar code technology.
Many
companies are investing in RFID systems today to get
the advantages they offer. These investments are usually
made in closed-loop systems - that is, when a company
is tracking goods that never leave its own control.
That way, they don't have to worry about their tags
being read by other companies. But most companies don't
have closed-loop systems. Since all existing RFID technology
is proprietary (meaning there are no standards), if
Company A tags a widget and sends it to Company B, Company
B can't identify the product unless it has invested
in the same technology from the same vendor as Company
A.
Another
problem is cost.
RFID readers typically cost $1,000 or more. Companies
would need thousands of readers to cover all their factories,
warehouses and stores. Readers typically operate at
one radio frequency. If tags from three different manufacturers
used three different frequencies, a store might have
to have three readers in some locations, increasing
the cost further.
RFID
tags are also fairly expensive - 50 cents or more -
which makes them impractical for identifying millions
of items that cost only a few dollars.
Creating
one, open global network for RFID means that companies
can invest in systems and have confidence that the tags
they put on their products can be read by retailers
and other business partners. It means companies can
share information about products and develop systems
that automate many of today's labor-intensive operations.
For example, when shipments arrive at a store from a
factory, the computer systems of both companies can
be updated automatically and an invoice can automatically
be sent. It also means that manufacturers of RFID equipment
can make equipment in vast quantities, since it will
work with anyone's system, which will help bring down
the price of both tags and readers. (There are other
issues related to cost that we'll tackle later.)
