Course Status

• This Course is a part of DEGREE PROGRAMME IN

INFORMATION TECHNOLOGY (Master of Engineering), which contains 60 cr

• This course will be held in english; all materials and lectures will be given in english

(4)

Course description

•

Learning objectives: The student will know the principles and implementation of different short range radio technologies. He or she can estimate the suitability of different technologies for various applications.

•

Contents: The student will learn different short range radio technologies like Zigbee, Chirp,

Bluetooth and other current technologies. (WLAN

is left out from this course because of the different

nature of the system)

(5)

Course description continued

•

Requirements: A course work (a presentation) and active attending to the lessons, also in the discussions after each student presentations and opponent role.

•

Literature: Teacher’s materials and students’

presentations

•

Prerequisites: No prerequisites needed.

•

Assessment: Grading scale 0 - 5.

(6)

Practical Arrangements of the Course

• The course will be held on Tuesday evenings, at 16.15, 3 hours per day starting at 2.11.2010

• At least one excursion to some interesting

company will be arranged. That can happen also in some other time than the usual lessons. The time will be agreed later

• There will be no exams in this course. Instead of the exams, every student has to participate at least 22 hours (about 80%), perform a

presentation and act as an opponent.

(7)

Course Timetable

• 2.11.2010: General topics, planning of the course 3h

• 9.11.2010 : No lessons

• 16.11.2010: Student presentations 3h

• Spring 2011: Practical exercises and/or excursion

• Altogether 28 hours

(8)

Student presentations

• Every student has to make a 30 min presentation on a selected topic and perform it in the appointed date

• The material for the presentation should be sent to the teacher and to the opponent in electrical format (Power Point is

preferred) by e-mail on Friday afternoon at 16.00 (before the presentation)

• The topics will be shown to you in a list. Reserve your topic as soon as possible, first lectures should be given after two

weeks!

• The lecture should last at least 30 minutes. After that there will be 15 minutes reserved for the comments and questions of the opponent and also other students.

• Student must also give a self-evaluation with good reasoning

(9)

The Opponent

• The task of the opponent is to read the material in advance and then at the presentation to ask clarifying questions that help the audience to understand the topic.

• The opponent will receive the lecture material by e-mail latest at 16.00 pm in the previous Friday before the

presentation.

• The opponent is also expected to give more detailed

feedback on the presentation than the rest of the audience.

• The opponent must also give his own evaluation of the lecture in scale 1-5, also with reasoning

• Also the performing in the role of the opponent affects the assesment of the student

• The opponents for different topics will be drawn out of a hat

(10)

Course Material

• All materials for this course will be available in the home page of the Telecommunication Laboratory:

http://www.tekniikka.oamk.fi/tl-lab

• You can access the page with your student username and password.

• The student presentations will be published in these pages as soon as the teacher receives them.

(11)

Assessment of the Course

• Main part of the assessing happens on the basis of the presentation:

– Teacher’s evaluation – Opponent’s evaluation – Self-evaluation

• A student must attend at least 80% of the lessons (22 h) to pass the course

• Also the performing as an opponent is evaluated by the teacher (from - - to ++) and has an effect on the grade

• Scale is 0-5

General aspects of Short Range Radio Technologies

• What are short range radio technologies and WPAN?

• Standardization (IEEE 802.15 and others)

• A short view on each short range technology

WPAN

A WPAN (wireless personal area network) is a personal area network - a network for interconnecting devices centered around an individual person's workspace - in which the connections are wireless.

Typically, a wireless personal area network uses some technology that permits communication within about 10 meters - in other words, a very short range.

A WPAN could serve to interconnect all the ordinary

computing and communicating devices that many people have on their desk or carry with them today - or it could serve a more specialized purpose.

(16)

A (new) standard family has been introduced for different WPAN connections, IEEE 802.15

A key concept in WPAN technology is known as plugging in. In the ideal scenario, when any two WPAN-equipped devices come into close proximity (within several meters of each other) they can communicate as if connected by a cable. Another important feature is the ability of each

device to lock out other devices selectively, preventing needless interference or unauthorized access to

information.

The technologies for WPAN are undergoing rapid

development. Most of the proposed operating frequencies are around 2.4 GHz in digital modes. The objective is to facilitate seamless operation among home or business devices and systems.
