Ubiquitous Computing
Go to the O drive, ICT, BTEC, BTEC
2013, Unit 1, LA A, Ubiquitous
Computing.
Find out what is Ubiquitous
Computing?
Lesson Objectives
• Identify the benefits and concerns of using
cloud computing and cloud storage.
• Understand the term ‘Ubiquitous computing’
• Be able to give examples of Ubiquitous
computing.
• Explain the benefits and concerns with
ubiquitous computing.
Benefit
Availability
Data and files may be
available anywhere in the
world where there is an
internet connection
You need to be able
to get through to the
host to access and
process data
The speed of
retrieval of data
may be slower
than it would be in
the local database
held in-house
Cloud
computing
and cloud
storage
You only pay for the storage
that you have used. You don’t
have to provide and maintain
hardware locally
Concern
As the files are being
stored by the host, you
have no control over
them. You need to be
aware of their security
terms and policies.
The host might
not be using the
latest, fastest
and most
secure version
Ubiquitous Computing
RFID Radio Frequency Identification systems
What is Ubiquitous computing
• Ubiquitous means ‘everywhere’
• Processors (computers) can be embedded in
any device including clothing, Appliances
vehicles, buildings and people to connect
them to the internet.
Radio Frequency Identification
(RFID)
• Currently RFID chips are used for Ubiquitous
computing.
• These chips use radio waves to transfer data
to a tag on a person or object.
• These tags contain information that is stored
electronically.
• It is similar to a bar code but does not need to
be scanned.
Examples
• Cat flaps that only open when the correct
animal that has a chip on their collar.
• Oyster touch cards to pay for travel in London.
• Agriculture – monitoring the health of
livestock.
Find three more examples and explain
the benefits for each.

Government
• Government – The U.S. Department of
Defence is planning to use RFID technology to
trace military supply shipments and in
soldiers.
• Benefits: this means that if any of the military
supplies go missing they can track them and
they can track soldiers.
People tracking
• People Tracking – The United Nations uses
RFID technology to track the movements of its
personnel.
• Disadvantages: people disagree with having
their lives tracked
• Benefits:if everyone had one there would be a
reduction of crime and birth cetificates etc
would not be needed.
pharmaceuticals
• Pharmaceuticals – Pharmaceutical companies
have embedded RFID chips in drug containers
to track and avert the theft of highly
controlled drugs, such as OxyContin
