Thank you Fanny and Alex.

Iron

Off the shelf equipment.

Iron

Both. standard and implementation.

 

Iron

Just want to know more of 802.11 in general.

 

Iron

Hi! from San Jose, CA.

HW/Test R&D Engineer.

 

Iron

both - implementation and standard

Would be nice to know about stability of 802.11 in industrial environment

Not sure yet on the price; still shopping around to see if this is worth the cost.  

Iron

The environment is similar to a small factory; somewhat harsh in that it is isolated from everything outside, but everything inside becomes that much more noise.  

Iron

MIMO may take more than that to understand, Alex! lol  But, I think that we have a pretty good base for it to move on a bit from here.  

Iron

I am interested in the specifics of the code/convention, but moreso in the actual setup and execution.  Also the troubleshooting.  

Iron

Again, predominantly hardware, but starting to dive more deeply into software.

Iron

Slides Are Great If You Didnt Get To Sign Up For THe Class

Iron

MIMO - understood well.

Iron

Learn more about the new 802.11ac.

Iron

Networking/Security.

Iron

fanny, 802.11af and 802.11ai have really wet my appetite for future applications. Thanks for the heads-up.

Iron

Thank you Fanny and Alex.

Day 1 and 2 added a lot of valuable knowledge to my problem solving toolbox. It was also a great way to briefly catch up on the basics of current RF systems, especially MIMO and beam forming in harsh environments.

Iron

@Alex, Fanny

Our company designs products for harsh environmental conditions; high vibration, -40C to +85C temp. Wireless communication and control is a question that comes up from prospective customers. Safety and failsafe design are parts of the designs.

is 802.11 OK for these applications?

Iron

@Alex, there was a question about what i want to know about 802.11?

Is there any affordable wireless technology, 802.11 or other that is appropriate for safety critical systems?

Iron

Better late than never, I'll listen to the archive audio

Iron

Thanks for great presentation

Iron

TGac? and TGad? stands for

 

Iron

Thanks Fanny, excellent presentation, leads to much thought

Iron

thank you all!  talk to you tomorrow.

Blogger

Some other creative antenna work is to provide optimum decorrelation between MIMO antennas (to increase MIMO performance) in a small device like a phone

Blogger

Bye Fanny, bye Alex and everyone else.

Iron

interesting antenna work is going on on making antennas broadband, for example antennas that can cover 700 MHz (cellular frequencies) to 6 GHz

Blogger

thank you, see you tomorrow

Iron

OK Folks, I feel there is no more activity. I will e-see you all tomorrow.

Iron

802.11 is more robust for harsh environemtns.  802.11n is not low power, but if you use 11n APs and low power client cards, this woudl still help.

Blogger

FANNY: This is way too interesting to miss. But I may need to comeback to read this discussion later. Got to go.

Thank you so much.

Iron

Fanny,

By limiting the power for the wireless connection to say 70%, Is that going to create a problem with say a laptop if at close range to the AP?

TIA

Iron

FANNY: Dipole is the firt chapter in a antenna text book Any one doing research that may influence the introduction of more advanced antenna cell design?

Iron

@Fanny, for low power systems that work in harsh environments and require decent range.  What would you suggest 802.11 or 802.15.4?

Iron

Thanks for the info, hear you tomorrow

Iron

So the antenna theory now needs to be understood by the SW engineers? :)

OK, everyone, this is great forum. I feel I need to go back to electrical engineering school. How about you?

Iron

regarding antenna design - it's a difficult skill to find, but now we use smart antenna technoclogy, which is basically DSP and works with regular dipole antennas

Blogger

Thanks very useful information

ah, thanks for clarification

FANNY: Manny year ago, telecommunication engineers had to learn about antenna design, which was the most dificult course in engineering school. Are folks still studying that and applying that kind of expertise inthe industry?

Iron

medium is singular; media is plural

Blogger

MAC - medium vs media -- do they mean the same thing?

regarding embedded Wi-Fi, I have a list of vendors and devices and can share it.

Blogger

yes... can you recommend any texts.

Iron

@Fanny, what vendors would have an OTS embedded low power solutions or evaluation kits?

Iron

the optimum way to position antennas is at 45 degree angles.  You shoudl use the same orientation of antennas (polarization) among all the communicating devies.  802.11 uses vertical polarization by convention.

Blogger

PHY os the OSI physical layer.

Iron

PHY = physical layer    MAC = media access control

PHY = physical layer; MAC = medium access

Blogger

Hi Fanny! Thanks for great presentation..Do you recommand any books on the subject?

Iron

Fanny,

In the 80211.n scheme I should position the dual antennas perpendicular to each other?

TIA

Iron

FTTH definitely helps since airwaves will get more busy over time, so any cabling that's available to interconnect base stations will be used.

Blogger

Fanny: I couldn't find definitions for PHY and MAC.  I think you said MAC is Medium Access Control.  What is PHY?

Iron

@ Fanny Fast initialization for mobile 60 mph or 600mph?

Iron

thanks!   (smartgrid using AES128)

Any suggestions on direction for harsh environments with little throughput requirements? Looking at low power (energy-harvesting) systems that push simple control information periodically.

FANNY: How do you see a FTTH helping the successful wireless cloud of the future? Microcells on poles?

Iron

for smartgrid they use AES128

 

Blogger
802.11n. (b mistyped)
Iron

Thanks for the response, Fanny! I appreciate all of the great information - "see" you tomorrow!

Platinum

Thank you for the session!  Looking fwd to the next few.

Iron

Fanny, just curious - what security is (typically or usually used) for smartgrid applications?  I can just imagine the hacking of utility meter transmissions...

Thank you, very good session. see you tomorrow.

Iron

collision avoidance in the overlapping channels has no good solution in the market, though 802.11n protocol has added some features to address it

Blogger
@Fanny. Any good technology evaluation kits for embedded 802.11 b
Iron

Thanks for a great session!

Pardon my ignorance if these techniques are already being used, but the last we need is a wireless version of Stuxnet into our WiNets.  Like military jamming techniques...

Iron

Collision avoidance in overlapping channels seems like a big problem - how is it being addressed besides hoping it doesn't happen? Are systems robust enough for packet recovery when it does?

Platinum

in some military implementations frequency hopping is used for security.

Blogger

Thanks.  FYI those without PowerPoint using GoogleDocs:  Your slides do not convert to Google format and almost all have unreadable parts as unconverted docs, due to incompatible fonts I think.  e.g. text runs off the bottom or under graphics.

Iron

small systems - off the shelf

Platinum

Smaller companies probably more ad hoc cobbling together...

Platinum

I was wondering the same thing about guardbanding - Alex. Interesting how we have progressed going from analog to digital...

Platinum

Collision avoidance in overlapping channels seems like a big problem - how is it being addressed?

Platinum

Multiple user MIMO is exciting -  I think I am grasping what Fanny is saying fairly well. Data rates and throughput over SISO are amazing.

Platinum

Fanny, thanks for explaining the difference between throughput and data rate!

Platinum

Understood Alex - we appreciate the opportunity to listen in!

 

Platinum

Hello Everyone - I'm looking forward to Fanny's presentation today!

Platinum

How is freq.agility used?  I heard it in passing.  I know that security will be a big factor in pushing wireless networking out across industry.

Iron

@Fanny, what vendors that would have an OTS embedded low power solutions?

Iron

thanks, great presentation

Thanks Fanny, Thnaks Alex

Iron

Thank you Fanny and Alex - very helpful summary of 802.11(a..xyz...)

hope we can see tomarrow

Platinum

Thanks Fanny and Alex!

Platinum

Very valuable info. Thank you!

Iron

NAN = neighborhood area network (smart meters); PAN = personal area network (802.15, bluetooth, ZigBee)

Blogger

Thanks fanny for an infiormative section

Platinum

Thank you Fanny!! Do you have any recommandation on Books?

Iron

Thanks for a great couple of Webinars.  Looking forward to the rest of the week.

Iron

FANNY: Nut-shell explanation for MIMO/SISO?

Iron

PAN = personal area network    NAN = neighborhood area network

Thank you Fanny, excellent presentation.

Thanks Fanny, good presentation

Thank you Fanny. I will back tomorrow for Zigbee!

Iron

Look forward to tomorrow.

Platinum

Thanks everyone for the number slide updates!

Iron

thanks fanny, another great presentation loaded with lots of info, thanks alex

Iron

@krhohio - I'm just after how to interface with the wireless unit.  There must be some sort of function call from the higher level firmware.

Iron

Lowest power spec ?  (Zigbee, Bluetooth LP, upcoming wifi ?)

Iron

thanks! Just like eithernet, 802.11 will take over.  Our electric company has gone WiFi for their SmartGrid implelentatioin

Blogger

Great presentation - very informative and interesting to see the dynamic development of the 802.11 standard. Looking forward to tomorrow's session!

Yes we will be here tommarow

Take a well deserved breath Fanny - Thanks!

 

Thanks for a great session today, Fanny

Iron

Thank you Fanny and Alex

Iron

How low is on the low cost device? Can we got from Digike?

Iron

didn't realize there was so many task groups

Platinum

@Ran: I think that the comm stack is embedded (i.e. not an API).

Iron

Stupid question:  What is NAN and PAN?

Iron

IF MARCONI AND MAXWELL RETURNED TO THIS WORLD TODAY, THEY WOULD BE AMAZED WITH THE MESS THEY CREATED. :O)

Iron

DDC == Data Down Convert?

Iron

for a novice is there a good development kit to get you started?

Platinum

@Fanny - Do the chip or module manufacturers offer the software for the comm stack via an API?

Iron

at what volume does it make sense to DIY rather than utilize a module?

Iron

@Fanny, what vendors would you suggest for OTS embedded low power solutions?

Iron

Fast initialization looks to be very exciting technology...that will be interesting to follow.

Platinum

Is 802.11ah is using 900Mhz band

Platinum

currently on slide 23

Platinum

you never get the data rate you want. (instantly)  We always want more data transfered, faster.

Iron

small systems - off the shelf

Platinum

@krhohio - Slide 20

Iron

Security IP camera applications

Iron

ALEX: Are you refering to the Shannon frequency?

Iron

Could someone please tell me what slide Ms. M is on?

Iron

embedded implementation

Iron

i'm hoping to build some small projects using wireless technology in an embedded

Platinum

Will need to pick a band and an architecture and try to stick with it as the company grows and adds capability.  3D models to CNC machinery, subtractive and additive processes.  Considering a leased environment to stay away from tech obsolescence.

Iron

for small instruments

Iron

Not right now. Just got some idea.

Iron

What slide please? (our IT dept seems to have blocked the streaming audio again!)

 

Iron

Large project - budgets in the multiple 100s of K$ for hardware plus labor at 2 to 3 X the HW cost

Iron

Intense planning ~150 sites, WLAN based RTLS systems throughout.

Need to add embedded soon though.

Iron

for now off-the-shelf; have done some embedded work (software) on custom hardware in past

target is limited range, low cost

Iron

small and off the shelf.

Iron

Not at the moment.

 

Iron

Embedded Solutions with off the Shelf components

Iron

inexpensive embedded systems (HW cost is critical) Turn Key is desired but not required.

i'm planning on doing small projects using cots.

Platinum

Alex, is the Q how much are we going to spend at digikey or in general?

Iron

Off the shelf equiptment mostly.

Iron

Northern illinois coverage.

Iron

mostly stepwise adaptation due to the changing of wireless technology, interop will be key consideration

 

Iron

adhoc, using COTS equipment

Iron

adhoc networks, hoping to use of the shelf equipment

Iron

Small projects with COTS

Iron

ad-hoc, building wide only.

Iron

ad hoc, if possible, OTS would be nice, if it worked

Iron

Small, cobbled, off the shelf, <#30 us

Iron

adhoc, small, inexpensive off the shelf network(s)

ANSWER: ARE YOU DOING INTENSE PLANNING OR IMPLEMENTING AD-HOC WI-FI NETS?

Blogger

Harsh: welding, multiple, variable freq AC aluminum welding, arcing, etc.  Robotic controllers, some shielded walls.

Iron

I was wondering the same thing about guardbanding - Alex. Interesting how we have progressed going from analog to digital...

Platinum

What would be the range for wifi

Platinum

The closer for WiFi the better the speed.

Iron

Mostly harsh factory environments, plus I have to design and test in a building that houses a facility that makes bomb fuzes.

Platinum

I upgraded from 802.11g to 802.11n router at my home, and wireless streaming is orders of magnitude better. Now I understand why.

may be in high rise building inviorment.

 

Iron

"harsh environment" - set up WiFi for father-in-law - 802.11n routers over longish line-of-sight (100+ feet) - still slower-than-expected throughput (or slower than I'd like...)

HARSH ENVIRONMENT: will need to be continuwously redefined. The more frequency band and protocols overlaps on the street, "harsh" will end up moving from the factory floor to the streets.

Iron

think later will design for military and/or space type enviornment

Platinum

Define harsh environment - I work for hospitals.  The buildings are NOT wi-fi friendly

 

not harsh, but many transmitters

Iron

Not at this time, but it is always a consideration when designing any system when trying to brainstorm future implementations - if can be designed in easily up front - could more easliy create a market solution later.

Platinum

Factory, desert, remote locations with advers weather.

Iron

Factory and Refinery plant inviorment

Iron

just normal indoors/outdoor environments

Iron

@Alex: if I hit refresh, I'm getting the audio stream from begining, I've tried many times, also with logout/login, still same issue

Iron

2-way WLS on a gas powered uP controlled lawnmower.  Harsh enough?  :)

No harsh environment

Iron

@Alex - If we were to impliment, it would not be so much a harsh enviroment as it would be a crowded (highly populated) environment.

Iron

Not at this time, but think I may have a need within a year or two.

Platinum

Large building with warehouse shelves.  5x 802.11g routers.

Iron

Yes..Remote open field for data collection.

Iron

not in harsh environment

Iron

Mostly Residential/Light Commercial Applications

Iron

Yes - Commercial/Industrial environments.

yes..mobile network in urban environment

Iron

Not considering harsh env at this time.

yes, network in a rural area

 

Iron

WHO's IMPLEMENTING IN HARSH ENVIRONMENTS?

Blogger

wireless on factory floor

Iron

Fanny@ Is there any diference for Antenna size in MIMO and SISO?

Iron

that explains a lot about my local wifi and the neighbors :-D

Iron

Beam forming clarification would be nice.  Can you expound?

Iron

FANNY: I wonder if wireless science will end up becoming a "babel-tower" big mess!

Iron

Collision avoidance in overlapping channels seems like a big problem - how is it being addressed?

Platinum

finally got audio back

Iron

agree with slide 13, what i'm use to seeing designing iff

Platinum

Any frequency hopping problem with 802.11

Multiple user MIMO is exciting -  I think I am grasping what Fanny is saying fairly well. Data rates and throughput over SISO are amazing.

Platinum

can you explain about wi-fi mesh networks?

Iron

ALEX: LOOKS LIKE SOME FOLKS STILL STRUGGLE WITH AUDIO.

Iron

@Alex - MIMO: Got it.  Differences between TGac and TGad is a little "iffy" right now.

Iron

I guess I understand MIMO... still unsure how beamforming works.

 

Clear on MIMO.  Hopeful lowest power choice is clarified.

Iron

think I have the MIMO OK

Iron

I'm comfortable with MIMO.

Iron

MIMo: multi Input, Multi Output

Iron

Got MIMO. No need for further insight at this time.

Iron

I now know what MIMO is about in general

Iron

After dropping audio, try refreshing the browser.  Seemed to work.

Iron

how/can you demonstrate determinism for functions

info about standards is good to have, helps understand arrogant vendors ... implementation details based on experience -- "how to" and "how not to" -- would be most helpful

Iron

Alex - I made PDF files of each slide deck (for myself - easier for me to use on two screens) - can I send them to you to distribute as well as the Powerpoint files?

are all these options on slide 7 commercially available today

Iron

this summary of the standards is helpful as well.

 implementation details
