We now have Nanoradio as the eighth and last company. With eight companies and 2x45 min that leaves about 10 min for each company including discussion. This means there can not be any longer presentations. Typically, five minutes would be sufficient. Also, if you have difficulty digging out technical data from the net you may need to focus on company data, products etc. /Dec 6th 2012

Industry Survey 13.00-15.00 Dec 7th. 1. Nordic semiconductor 2. Texas Instruments 3. NXP semiconductor 4. Teleanalys 5. SiversIMA 6. IMST 7. Qualcom. Max 15 min per company. You can present and/or we can discuss the company jointly. You may use the projector. If you need help to copy or use course laptop you can mail material in advance. The written summary is best mailed to me in advance in either case.

At L19, last lecture, we will present the industry survey. You will now need to choose your company asap. See download page for instructions. /12 Nov 2012.

Comment on Lecture notes on download page: They represent selected topics from the text book. As the text book covers more material it is suggested to use the book as refence for and explanation to the slides rather than to read full chapters.

Forskningens behov av gratis radiofrekvenser FYI, 2012-11-05. Free seminars on need for free frequencies. (in swedish).

If you have not chosen this course, do so before course start or it will not be possible to register you.

Radio Electronics, IL2219, period 2,  7.5 credits
Lectures 25 hours, Exercises 13h, Labs 16 hours
Written exam

All Digital Radios are Analog!  i.e. Basic Analog Electronics prerequisite.

2009 marked the 100 year anniversary of awarding the Nobel prize to Marconi and Braun for their work on “wireless telegraphy”. Today the field has a new high point with a multitude of innovative devices coming out onto the market and understanding them has become a must. Much of the global success is based on pioneering research work on mobile communication performed in Kista throughout the last decades by Ericsson, Telia and universities. This course covers how radio devices operate in a network and how they are designed from electronic building blocks. After the course you will understand how wireless devices operate in a system and their inner design.

Explosion of Radio devices last 10 years and more are coming…

- Mobile communication 1G-4G  (>1 billion devices sold per year), speeds up to1000Mbps in a few years
- WLAN- eg. laptops, smartphones
- Bluetooth
- Broadcast: DVB-T, DVB-S, DVB-H, DVB-C
- RFID (internet of things)
- GPS
- ISM- unlicensed frequency bands
- and many more…..                                                                                                               Android Smartphone
