Abstract

The topic that is covered in this paper is how hospitals are using
RFID Ultra

Wideband. Ultra

Wideband is a transmitter of data
over a wide array of bandwidth with only little power. It was only
used by the military, but now used commercially. Ultra

is so popular in the medical field, because it does not interfere with
other machinery. The things that I will cover in my paper are:
What RFID Ultra

Wideband is, how it works, the frequencies, how
it is used in hospital settings, and what it can do

for educational
settings as well.

With the ever growing technology today, we are in need of
more systems that help us get the job done. Data communication
has got so big and will only get bigger in the next couple of years.
One of the systems that are widely used today is the RFID system
.
It was only used by the military, but now used commercially. What
is RFID you might ask? Well RFID stands for radio frequency
identification. It is a device that stores and retrieves data using the
RFID method. “RFID relies on radio waves and doesn’t
need a
line

of
-
sight to read data. In place of a barcode, you have an RFID
tag or “transponder,” read by a hand

held reader, door
-
mounted
reader, or some other configuration (Staff). RFID is used in our
everyday lives. RFID tags can be found in the tran
sportation
industry, consumer products, drugs and food IDs and shelf life
indicators, patient identification, smart houses, and intelligent
wearable. Many industries have adopted the use of RFID.
Probably the most of us have seen these used by clothing s
tores
that have to be removed or deactivate the piece that is attached to
the garment or will make the alarm beep. By them using this
technology, they are sure to be able to be more effective in

operations, reduce the costs, and even reduce errors that c
an occur.
This is one system that will only get more sophisticated with time.
In the remaining part of this paper, you will learn how RFID
works, the frequencies, how it is used in hospital settings, and what
it can do for educational settings as well.


In order for the RFID system to work, you must first make
sure that you have all the components that are required to have it
work. The components on the system includes: tags, readers, edge
servers, middleware, and application software. “An RFID tag is
a
small object, such as an adhesive sticker, that can be attached to or
incorporated into an object (anything from a pallet of laundry
detergent to a racecar tire to a pet’s neck) (Goleniewski pg. 675).”
An antenna is used to capture data from the RFID ta
g. Once the
data is received, then it is sent back to the reader. “A small tag on
a device or person emits a radio wave that is detected by a network
of receivers around the hospital. Software crunches the positioning
data and puts the locations on a ma
p or table or into a hospital
information system (Page).” The good thing about RFID
technology is that it works in all kind of weather conditions. There
are three types of different RFID tags. These include: read
-
only,
read/write, and write once, read m
any times (WORM). RFID can
also be classified as active or passive. Active RFID tags have the
power source and have larger memories then passive tags. Active

RFID tags can be used to communicate up to 100 feet from the
reader. They are also more expens
ive. The battery life of an
active RFID tag can be up to 10 years. On the other hand, passive
RFID tags do not need battery or power supply. Since they do not
need either on, this only means that it has an unlimited life span.
This makes the passive ta
g cheaper of course. The RFID
frequency bands vary. It can be categorized as low, high,
ultrahigh, or microwave. Using microwave will give you a wider
frequency band of 2.4 GHz and 5.8 GHz which will also cost
more. The range of these bands, range from

3 feet all the way up
to 100 feet. Depending on what the RFID tags will be used for,
that is how you will choose which one you will need. All the
things that will need to be considered are: the distance needed,
speed, and cost.


RFID is something that

hospitals are using more than ever.
It is a way that they can be sure to be able to operate the hospital in
a more effective way, help out the nurses as well as doctors, and
also help out the patients. You have probably seen some of these
tags in some o
f the hospitals today, but just did not know what they
were exactly. Most hospitals today have adopted this new system,
by giving each one of their medical staff personnel and body
