Thank you very much madam Fanny

Iron

Good evening from Bremen/Germany

Iron

great and excellent presentation madam fanny and will be back for the day 2 class lesson which is already on archived to click on...

thanks to the digikey and design news...bye.

i am now on slide 16...it's nice to learn which is not totally part of your job. but learning it through and listening like this presentation is an educational and advantage for me...thanks.

i am now on slide 2 of the presentation...

i am in the field of building services engineering industries...

i am just downloading the presentation slides prior to start with the discussion of madam fanny...

good afternoon madam fanny...i am here for your class day 1 presentation...

Telemedicine device for the healthcare industry

Iron

Not in wireless industry yet. It is everywhere, so it is time to know it.

no specific project, so I am not working with ether mimo or not.

Iron

not workiing on any wireless applications.  just general interest.

Iron

I am working in aerospace.

Iron

Very cool presentation.  Thank you!!

Iron

@Ann - re. the applications... LTE base stations, small cells, standards, etc...

Iron

@Ann - re. the industry... telecom infrastructure vendor

Iron

Great to have access to the recorded sessions!

Iron

I appreciate your time and information

Iron

Good information on wireless testing standards

Iron

Good review of wireless standards.  Thanks!

Iron

a belated thank you

Iron

Thanks a good review 

Okay a quick review for the week

Thank you Fanny! 

 

Iron

Working on 802.11 wifi TV

Iron

Hi all, is there a class at 2 today?

 

Iron

I'm glad you were not put off from all the interuptions and fighting with the moderator that occured on the first class

picking up another day a few days late

Thank you for sharing knowledge in wireless technologies. What is the difference between throughput and data rate ?

Iron

I'm here for the archive.

Iron

Wireless applications are lighting room occupancy/light level/lighting control systems. Simple low frequency low bandwidth, low power systems.

Trying to catchup - Lighting control systems (used to make RF test equipment)

Interesting class and then I'll read them some questions about this issue or any particular topic

I am student at IIT. Thank you I really appreciate.

 

Iron

Thank you Fanny.  The technology has advanced so much since my exposure to GSM in '96.  Thank you for your educational insight

!

Gold

Thanks Fanny!

I appreciate your sharing of knowledge in latest wireless technology.

I'm curerntly a Novice user for 802.11n and have added a few new books to my reference library since your last Class on Wireless Networks; O'Reily-Safari Books: 802.11 Networks The Definitive Guide 2nd Edition, and the more recently published 802.11n Survival Guide by Matthew Gast. Also dounloaded the pdf version of Part 11: Wireless LAN Medium Access Control (MAC) and Physical Layer (PHY) Specifications by the IEEE (802.11-2012).

TIA

 

 
Iron

Thanks for the class. It was very informative, which is what I have come to expect from the classes I have taken on this site so far.

Iron

Thanks for the great presentation Fanny.. see you tomorrow

Iron

Thank you for the presentation!

Iron

Thanks for spending your time with us.

Iron

Thank you for today's presentation Fanny

Iron

What books/website do you recommend on learning about the mentioned techniques?

Iron

there are sophisticated forward error correction tequinques that are evolving for both Wi-Fi and LTE (e.g. Convolutional coding, LDPC)

Blogger

IEEE 802.11ac Hardware Implementation

Iron

the allocation units are in RBs, so - yes - even though this may be wasteful for some low data rate transmissions, the entire 180 kHz is allocated for some time slot

Blogger

With more bits per second, how is the error detection evolving? what is the acceptable amount of bits that can be missed for a "good" signal?

Iron

But for a short burst of data, will the radio transmit only a 15 to 30 kHz BW signal, or will it occupy the entire 180 kHz?

Iron

RB size is the entire 180 kHz

Blogger

underwater signaling is optimally done using acoustic frequencies

 

Blogger

SoC for Wireless Communications

 

Iron

thank you Fanny for the presentation.  For the RB being 180 kHz, when a transmission is made, will it be the entire 180 kHz or any multiple of 15 kHz?

Iron

Great overview Fanny! I appreciate your expertise and ability to simplify for explation. I'll be back all week for more!

Iron

What are the MIMO enable WI-FI devices in todays markett?

thanksfortheinfo.great!!!

[replacedtest1]id="__changoscript"type="text/javascript">//

Some of thsoe settings on my radio transmitters are far more clear now. Even using them as a consumer with laptop wireless was a challenge at guessing the settings.

Iron

Thank you  fanny

William R. Merkel

Iron

Thank you Fanny!

 

Iron

@Fanny - thank you for an excellent presentation - see you tomorrow

Iron

good lecture, thank you Fanny

Iron

Josip: Wavelets. Look for Haar Transform etc. e.e. http://amath.colorado.edu/courses/5720/2000Spr/Labs/Haar/haar.html

 

Iron

Thank you I will be there Tomorrow...

Iron

Fanny, a nice overview to start the week. Looking forward to the rest of the weeks lectures.  Thanks.

Iron

thank you Fanny,

Iron

Fanny, in a previous slide, you mentioned that a Resource Block (RB) of 180 kHz is a whole radio.  Is there a maximum power that a RB can transmit?  Fo example, for a 40 W eNB covering a 10 MHz BW, if ALL 50 RBs are transmitting then 0.8 W per RB is used.  If only 1 RB is used, can it transmit at 40W?

Iron

DaveWR:thankf for the advise ''waveltes''

Josip: Found at low freq FFT is useless -- look to waveltes or similar. I did not know "waveltes" existed -- developed similar techniques. An engineers later pointed out the similartities.

I should get a TI CORTEX M3 test unit from Digikey today -- will test expanded capabilities as soon as I convert collection software. Seminar on Micro Dev Kit Choice led to that decision. Will blame John T if it does not work.

 

Iron

@RF_Robert - yes - type your question/statement in the box obove the post, then click the post button to send

Iron

DaveWR; o i need a 16bit

Josip: BTW -- that was serious suggestion. I finished development day before Japanese Tsunami. Did not hear news reports and spent a day tracking down bizarred noise bursts -- later calculated delay times and looked at signals -- sure enough it was conincidental. You may need something else above 3KHz -- but works well for Infrasound and long period vibration.

Iron

First time here.  Is this POST section where we ask questions?

Iron

Very Good, presentation

Iron

DaveWR: spectogram looks clean for example if i see a click ,but the timewave form FFT(It is mixed with noise so it hard to analyse :-) 

Wireless industry - 4GLTE

Iron

Josip: Sure BOSCH BMA180 accelerometer. -- Using interrupts ion an embedded micro. :-)) Works well.

Iron

I am an applications engineer working on Layer 1 implementations of LTE CDMA-2k, and LTE-A for several customers at a Semiconductor company

Iron

there are some new multimeters made by FLUKE that allow the display to be as far away as 20 feet from the sensing unit, thus allowing the user to be a little out of harms way, if it's being used on high-voltage, etc. works on bluetooth

Can't hear the moderator very well. The instructor is loud and clear.

Iron

DaveRW:im using 300khz band with 626.566khz sample rate for A/D underwater detection systems

and i have some trouble from 0>6Khz ,do u have any sugestions or something for those low frequencys

in order to detect them and read them easier.

 

thx

I'm an instrumentation & control specialist at Turkey point nuclear power plant, we just recently started working with wireless data acquisition and measurement equipment

For those just joining us, please tell us what industry you're in, what wireless applications you're working on, and whether you're working with MIMO or SISO based radio.

Also, if you can't hear the audio, please note that some companies block live audio streams. If you don't hear any audio, try refreshing your browser. The session will be archived shortly after it ends.

Blogger

Josip:  If you mean detecting of LFN ... I look at 300HZ down to the "seconds per cycle" noise patterns. Those patterns are not unusual for LFN detection. I wrote custom software for freq, detection as FFT etc. don't seem to do much (useful). Similar to wavelets analysis. Packets are passed up to PC for storage in DB and further analysis -- graphing and math analysis etc.

Iron

@sara.bavarian - sometimes the audio will be interrupted (stopped) if you click on a link on the page or some other activity. just happended to me. simply refresh your browser

Iron

Audio has stopped!

 

Right now we are not working, but in future we might use.

Iron

I'm having trouble with the audio. Thanks JL.  I will go for the archived.
