Q:

DO YOU SUPPLY UTILITIES OR COMPANIES WORKING ON SMART GRID? WOULD YOU LIKE TO AND WHAT WOULD IT BE?

A: My Electric and Gas Usage. From home to the Utility Company. Don't have any control of it.

Iron

No LARGE AREA Applicatios

Iron

Hello from San Jose, CA

HW R&D Engineering

Iron

It is good to know what technology is currently in use and how it is progressing

Thank you for another great presentation Fanny and Alex.

Iron

I think that I was mostly looking for a general introduction to wireless, but on a more technical level, so I think this serves me very well.  

Iron

The area that I am focusing on primarily is a smaller, indoor area.  

Iron

My focus is primarily on hardware, but I am branching out to software more as of late.

Iron

Thanks Alex and Fanny. The topic is very ineresting for me as a FAE for wireless product. HOwever, this audio archive is wrong. It stops in half way about 17 minutes only. Can you help to fix it?

Aaron

Iron

BY THE WAY MY INTEREST IS TO APLY WIRELESS CONTROL INTO NUCLEAR GLOVEBOX TECHNOLOGY TO REDUCE THE NUMBER OF PENETRATIONS AND THEIR INHERENT LEAKAGE THROUGH THE GLOVEBOX WALLS.

Iron

ALEX, THANKS FOR YOUR INTERJECTIONS ALSO AND FORGIVE ME FOR CALLING YOU MAX YESTERDAY.

Iron

THANKS AGAIN FOR INTRODUCING US TO A WIDE AND RAPIDLY EXPANDING AND EVOLVING FIELD.

Iron

Networking/Security area.

Iron

In response to Alex's question on supply, am not presently involved in supply to Uitlity.

Iron

In response to Alex's question on roles, my primary project role is HW design.

Iron

The bee keeping comments are very interesting also

as I also have kept bees in the past

Alex,

I appreciate the passion but find your questions/interuptions break the flow of the presentation

Picking up anothr missed episode

It's been a very long day for me.  Now I've got to catch some ZZZs.  Good night to all.  Sleep tight to night, your Air Force is awake!

Iron

Thank you Fanny, and thank you too Alex.

Iron

ANSWER: FOR TOMORROW, FOR OUR WRAP-UP CLASS IN THIS TRACK, WHAT ISSUES IF ANY WOULD YOU LIKE EXPLORED OR DO YOU STILL HAVE QUESTIONS IN?

 

I'd like to see some charts that include the ranges of various means of wireless standards.  Do I choose Wifi, ZigBee, Bluetooth, etc.  Some examples of what equipment that would be needed for developing would be good.  Chart forms would be nice for these items.  I know it would be large/extensive, but so is the wireless field.

 

Also, an acronym listing would be nice.  It would have been nice to have such a listing on day one of this week.

Iron

ANSWER: ARE YOU INTERESTED IN THE INTERNET OF THINGS?  WILL YOU SUPPORT IT AND WHERE DO YOU SEE THE MARKET OPPORTUNITY?

 

Most definitely.  Nearly everything is being connected via the Internet.  Designing without knowing how to connect via the Internet will be the death of a design career.  I realize that not everything will have connectivity, but not having the knowledge will lead to certain death of an otherwise career.

Iron

ANSWER: WHAT PROTOCOLS DO YOU NEED TO KNOW MORE ABOUT?

 

I don't think I would restrict my interests on any single specific protocol, but rather on a comparison of protocols.  What protocols are used where and why they are chosen for their applications.  What the pros and cons are for each that support their choice for a given application.

Iron

PLEASE ANSWER: WHAT ABOUT THE SMART GRID ARE YOU INTERESTED IN LEARNING? ALSO, WHERE ALONG THE SMART GRID IS YOUR MAIN POINT OF ENGAGEMENT, from power plant to home.

 

I'd be more interested in the development of the equipment used within the infrastructure of the smart grid.

Iron

DO YOU SUPPLY UTILITIES OR COMPANIES WORKING ON SMART GRID? WOULD YOU LIKE TO AND WHAT WOULD IT BE?

 

I do not work on supplying the utilities or companies working on the smart grid, but I would enjoy working on the development of the various tools used by the utilities for the smart grid.  Any of the HW/SW/FW would be a pleasant challenge.

Iron

@Alex - Large Area Applications: None at this time.

Iron

@Alex - Major area of focus: HW/SW/FW

Iron

Sorry I missed today.  It couldn't be helped.  I'm not sure if in addition to using the .ppt and listening to the presentation if I should be posting.  I don't know if my posts will be archived and if anyone will read the posts, but I'll proceed as though I were here at the normal time.

Iron

Thanks great presentation

Thanks Alex, Fanny, and all! Although I learn RF and have used in some of my projects, this week program humbled me, with so much to know. I am glad that so far I have kept myself busy with wired infrastructure and software. There is so much out there to learn. :o)

Iron

@Fanny - Just to clarify, Re the clock rate reduction:  the signal being sampled is the main carrier mixed down to baseband?

Iron
Thanks. Will check it out tonight.
Iron

for vehicle to vehicle networking the ITS industry is considering LTE and 802.11p

Blogger

Fanny, which standards are being considered for vehicle-to-vehicle networking (such as along a highway). And similarly, what's being looked at for vehicle (cars, etc) trackig along streets and highways?   Sorry if this is a double post.

Iron

www.octoscope.com has an Articles page where you can also find white papers and test reports.  feel free to email me at fm@octoscope.com

Blogger

 Fanny,

Nice Presentation today. Is there anything that you can share about how the move to PTC (Positive Train Control) will fit in with the Smart Grid when it becomes fully deployed?

TIA

Iron
Octoscope Any pointers where to look for info??
Iron

reducing the clock rate refers to reducing the sampling rate - the rate of actually generating the samples so narrower channels require no extra logic in the chipset

Blogger

Thanks Fanny for the great introductory information. Today, and the past few days have given me a good start to understanding and preparing for the variety of wireless systems.

It also may have revieved an interest in RF again.

See you, Alex and all tomorrow.

Iron

lightweight security can be implemented at the PHY layer - non standard solutions exist

 

Blogger

thank you fanny and alex

Iron

Thank you Alex and Fanny and DIGIKEY..very informative and helpful.

Iron

re data collection, please see lectue 3 slide 4:

IBM's Cognos software and other analytics products determine power consumed by appliances (e.g. air conditioners) and analyze power consumption trends among households.

 

Blogger

LOTS OF INFO. thanks Fanny

Yes!  THANK YOU DIGI-KEY!!

Iron

THanks Fanny, see you tomorrow!

Iron

Thanks Fanny for the informative lecture. 

 

Iron

Thank you Fanny and Alex (and again, Digi-Key)

Thank you Fanny.  Can't wait for the implmentation presentation.

Iron

Thanks Fanny and Alex-I'm looking forward to tommorow's session!

Platinum

@FANNY: On Slide 6, OFDM Considerations:  "Narrow band operation is achieved by lowering clock speed (in the DSP, I think you said)":  Are you talking about reducing both the sampling rate (I assume you are sampling the carrier baseband?), and the DSP processing rate, i.e. running the same processing code at a slower rate to match the sampling rate?  Seems like there are some unstated assumptions about the processing mechanism.  Thanks for a great course.

Iron
Sorry that was encryption.
Iron

off-topic - Fanny - funny you mentioned bee keeping - my neighbor just told us he's getting some bee hives

see you tomorrow, cheers

Platinum

FANNY: Is there any traffic data collection and analysis being done for the smart grid and Internet of things?

 I currently have a list of 35,000 achronyms

 

Iron

Fanny are you a beekeeper? I am too..and that is my goal for with wireless monitoring

Iron
For security is there any lightweight solutions yet. Full en typhoon is too costly to implement on small mpus.
Iron

Thanks, very nice presentation.

Iron

security - ignoring data security - simple signal jammers

Thank you Fanny - interesting, new views.

Iron

Question for Fanny for tomorrow: Interest in techniques and low-cost test equipment to check for radio interference that could occur in 802.11 or other wireless standards. If Wi-Fi network is experiencing interference or impairment, how can we capture, observe, quantify this?

Iron

CyberAttack is possible from Communication as well as from High Power System.  Are there any common strategy for security from so many directions?

Thanks Fanny. Very good presentation
Iron

thank you very much Fanny

Iron

thank you Alex, till tomorrow

Iron

Thanks fanny for the clarification

Platinum

thanks!! really enjoyed presentation.

Platinum

@JM Ashcraft: 802.15.4g was appproved by IEEE on Mar 29th. 802.15.4k and 802.15.4m are WPANs currently at task group stage (http://www.ieee802.org/15/). 802.15.11ah and 11.ag sub-GHz WLAN

That is a very good question Alex!!!

Iron

Thanks for another great presentation.

Topic to cover Friday: Quick comparison of costs to sponsor organizations to use ZigBee, Bluetooth, NFC & other standards.

Iron

interested in developing small home projects using wireless technology.  any suggestions on the best way to start, like development kits?

Platinum

which technologies are most likely to end up on top in Fanny's opinion??

Iron

D block prison - well, there *are* Guard bands...

thanks fanny, another great presentation

Iron

Would like some comments on relative cost of using the various communications technologies.

Iron

Question for tomorrow: wireless standards for handset (mobile phone) compatibility? aside from the obvious wifi and bluetooth, any other standards poised for wide deployment (ex, ANT)?

Iron

Thank You Fanny 

 

Iron

Fanny, that means Ps is also duplex

Platinum

ANSWER: FOR TOMORROW, FOR OUR WRAP-UP CLASS IN THIS TRACK, WHAT ISSUES IF ANY WOULD YOU LIKE EXPLORED OR DO YOU STILL HAVE QUESTIONS IN?

Blogger

What are the companies make silicon for PS band radios?

 

Thanks a lot Fanny. Leart more from you.

Iron

Thanks for a great session!

which 802 standard is best to get involved in?

Thanks Fanny for your good and informative section

Platinum

Fanny..plese recommand books on the subjects.

Iron

What makes 802.16/LTE have wider range than 802.11? Is it TX power?

Iron

Thanks much Fanny..you are really a great bank of knowledge.

Iron

Any organizations or bodies are there for standardization

Platinum

side comment - valid8.com is working on test suites for P25 equipment

some public safety 911 centers had a problem tracking or determining the caller's location who are moving and using their cell phones, as they upgrade their equipment will this solve this problem?

Platinum

It appears to me that the "heart" of the smartgrid from the perspective of an individual or business is their power meter.  According to the smartgrid concept, the power company would be changing power rates dynamically and providing that information via the meter base for user-side devices to behave accordingly for.  Is that true?  Is there more to it?  If so, the two critical pieces of information for design are how to get that information from the meter, and how to avoid colliding with your neighbor's information (sharing airspace as well as keeping all the devices in the correct network).  Where do I find information about those two items.

Iron

What's the key to convince stable customers to switch from analog to digital network? cost? technoloy? base station? 

Iron

@luizcosta - start here: http://www.3gpp.org/ftp/Specs/html-info/21905.htm

Iron

Standardization seems so be a big challenge

Platinum

why there is 2 C and D Block

Platinum

just make sure you keep your bills paid

coast-coast LMR? There are utilities and sysytem integrators reusing 930 MHz paging band which provides for coast-coast coverage using mFSK modulation

 

what would be the best for instrumentation in a refinery or factory application?

 

Iron

interested in both IPv4 and IPv6 protocols

Iron

How does RFID play in all this?

since the budget problem!

Iron

luiz - Newton's Telecom Dictionary

yes - internet of things, machine to machine communicatio

Iron

Smart frig would have to have everything rfid'd, something a lot of companies do not want to have the cost

Iron

700 MMhz is only for public saftey or any other dulex communication is possible

Platinum

Are we still using LMR these days in US?

 

Iron

P25 is very interesting - came out of problems after 9/11 - allows intercommunication between first responders, as well as sub-groups within the radio

ACHRONYM DICTIONARY: I begining to look at developing an achronym dictionary in Telecom and IT. Any one intereste in contributing is welcome to send e-mail to luizcosta@sbcglobal.net

Iron

sorry "generate" a shopping list

Platinum

radio scanning was a fun way to spend weekend evenings, listening to police and the old analog cell phones.

Iron

I am interested in both IPv4 and IPv6 protocols

Iron

think i remember seeing several years ago a refrigerator that would allow you to either scan a bar or enter information about its contents. you would then be able to generator a shopping list.

Platinum

START ENTERING YOUR QUESTIONS FOR FANNY. SHE WILL COME ON THE CHAT HERE DIRECTLY IN A LITTLE WHILE.

Blogger

I don't want my appliances talking about me on the Internet "you should see the mess this guy left"

Iron

QoS: This is the biggest challenge, for the industry has abandoned solid telecom ATM (asynchronous transfer mode) technology, and embraced shared ethernet. What is your take on that?

Iron

I hope our power company is listening to this - would be good to have them repair outages faster!

Iron

Yes..Interested in the internet things.

 

Iron

slide 15 - especially interesting to see the mention of distributed power generation

time will help all things to integrate if we want them too.

Iron

IoT - How is your toaster feeling this morning ? How old is that milk in your refridgerator ? Hmmm, another solution looking for a problem.

Iron

it seems the "internet of things" is more immediately applicable to our infrastructors, i.e. utilties

Iron
Only problem with homeug is slow adoption
Iron

I don't trust having all devices in my home/work/vehicle to be in constant communication and control to the outside environment. Too many ways for things to go wrong.

Iron

Yes,interested in internet of things

Iron

We will be looking at it to show status of fuel tanks or other devices

Iron

Internet of things for my personal usage initially: transmitting temperature and weather data.  Maybe later for factory automation to transmit data.

Iron

yes, have a general interest in the Interet of Things. no direct apps yet.

Iron

are there tampering concerns with smart grid and/or AMI

Iron

(oops... spelling...   * sense * )

Yes machine to machine
Iron

Yes interested in  internet of things.

Iron

seems to me homeplug makes a lot of sence for a lot of this, rather than wireless

Sub GHz is going to be a better medium than 2.4 GHz for FAN / AMI and probably has advantages for HAN. Look at 802.15.4g and 802.15.4k for utility endpoint FAN / AMI.

Currently employing it.

Iron

General interest in Internet of Things at this point. No project plans at this point.

Iron

I see some of our potential customers needs access to their devices while away from the factory.

 

Iron

I don't see any alternative to be interested in the Internet of Things.

Iron

yes - internet of things, machine to machine communications, etc...

Iron

yeah we could use those super conducting wires we've been looking at for decades, right about now for better transmission lines. :-)

Iron
Zigbee and moving to 802.11 if Zigbee is outgrown
Iron

ANSWER: ARE YOU INTERESTED IN THE INTERNET OF THINGS?  WILL YOU SUPPORT IT AND WHERE DO YOU SEE THE MARKET OPPORTUNITY?

Blogger

QUESTION: I don't see a wireless only communication world. Do you?

Iron

smart grid Goals, any plan to reduce the attenuation and transmission losess

Platinum

Very nice slide on smart grid overview!

Platinum

can bluetooth and zigbee use the same grid.

I am not sure. May be Zigbee for me? what protocol is suitable for low speed wireless sensor system?

Iron

Wireless CAN. Still looking for a good solution.

Iron

in learning mode so any protocol but like ip

Platinum

6LoWPAN over 15.4 - look @IP500

 

can you compare PoE and homeplug?

 

Iron

protocols - those that apply to these technologies

Iron

Sorry, I'm a bit behind today... what is the best Smart Grid "general info" web site?

Iron

Interested in proprietary ZigBee-like protocols

Iron

ZigBee is high interest, but we may have to go smarter if the customer wants us to

 

Iron

6LoWPAN over 802.15.4

Iron

8B/10B and parity bits

Iron

looking at 802.11 and 802.15.4

Iron

any certification programms are available for testing

Platinum

i would imagine interoperability between all.

Iron

ANSWER: WHAT PROTOCOLS DO YOU NEED TO KNOW MORE ABOUT?

Blogger

less interested in the application layer...

Iron

Slide #3
EU ISM band is 863 - 870 MHz (Annex 1g of ERC 70-03)
PRC ISM Bands 470 - 510 MHz, 702 - 787 MHz (15.4g targets 779 - 787 MHz of this upper band)

Slide #8
Si4432 is not a SiP / SoC

thanks for that information i always think power companies when i think smart grid.  i will check out the other companies

 

Platinum

Interoperatability between what, different grid or communication hub

Platinum

Securing everything is what we do here.

Iron

sorry... safety critical

Iron

JM : Try different browser or restart browser/computer

Iron

one point that we concentrate on here is failsafe operation in safty critical systems.

Iron

We do alot of work in the home power side, solar and wind mostly.  Smart grid for that metering and extended aplications is what I am looking at.

Iron

Industrial applications eg. re-gen AC Drives

Iron

Home to multi-building environment for us.

Iron

More interested in smart metering than smart grid

Iron

no smart grid as yet 

Iron

Why licence is not required?

Platinum

I am looking a wirless solution for a multi-sensor project.

Iron

general understanding

Iron

Z-Wave can have big problems since it has only one possible narrowband channel. If it is blocked by interference, Z-Wave can't operate.

Iron

I don't know enough about smart grid to have a specific area of interest.

Iron

Mostly interested in home environment.

Iron

Why licence is not required?

Platinum

I'm implementing sensor networks with long range in harsh environments

 

Iron

interested in home applications

Platinum

PLEASE ANSWER: WHAT ABOUT THE SMART GRID ARE YOU INTERESTED IN LEARNING? ALSO, WHERE ALONG THE SMART GRID IS YOUR MAIN POINT OF ENGAGEMENT, from power plant to home.

Blogger

More towards the hom end.

Iron

I am interested in weighing the FTTH + wireless in the premisses versus Power Line Communications Wireless in the premisses.

Iron

What can be done to improve interference in these applications?

Platinum

interested in sensor networks with a range of a couple of miles

Iron
Nothing for utilities or smart grid
Iron

echo problems...refresh didn't help.  any suggestions?

Hardware and software
Iron

QUESTION: Chip level of off the shelve choices mayl depend on the scale of deployment. If I have 5 years to deploy a smart grid application, would it be economical to go custom design for 55,000 homes?

Iron

Noise and jamming technologies are the biggest issues we are fighting with

Iron

what slide are we on?

Platinum

Is more than one Smart City in the USA?

narrower band operation is achieved by lowering clockspeed,what about the frequency changes

Platinum

Probably using chipsets

Iron

narrowerbandoperationisachievedbylowering,whataboutthefrequencychangesclockspeed
Platinum

We have our on design, since no one makes or uses the technology we use or require 

Iron

no, maybe in the future

Iron

Last discussion about Smart Grid communication net was halted with security up to HV transmission system.  Any new trends in this matter / security barriers?

I will be doing chipset too.

Iron

Yes, We have a group working on Smart Grid Tech

Iron

We are building consumer side ems using smart grid, remote environmental sensors and equipment consumption data

Iron

We probably will use something pre-assembled and set-up to match our sensors

 

Iron

Yes, would like to supply irrigation water level flow meters to irrigation company via periodic measuring devices.  Long distances are involved with low accessibliity to power and maintenance.

Iron

No, no utility company smart grid products currently.

Iron
Good afternoon everyone
Iron

I will be buying the chip set.

Iron

no smart grid work at this time

No - We are not suppliers to utilities for smart grid

Iron

@alex - can you post the question

Iron

no supply to smartgrid

Iron

no, not sure this will be in my future

Platinum

Nothing to utilities for smart grid at this time.

Iron

Interested in the blend of wireless FTTH in the public utility setting.

Iron

Long distance people --- (>2miles), how are you planning on doing that?  WRT regulations and power consumption.  Do some of those standards account for up to 25 mile transmissions?

Iron

QUESTION: Are there any traffic study for the smart grid?

Iron

I MAINTAIN hardware for outdoor control applications.

interested in learning more about wireless networks

Platinum

@Laith, try browser refresh. it does that to me too.

Iron

How wide? Factory, Warehouse Management System.

Low traffic. 10+ APs. 20-50 clients/AP (range).

Iron

I am a graduate student.  My interest in radio communications is for robotics communications and also home area networking.  Currently no large area networks planned.

 

Iron

my apps stay indoors, be they wired or wireless. factory floor stuff

Iron

large area app - none

Iron

Smart grid- collection of communication hub or any other forms of grids

Platinum

no immediate application, just building my problem solving toolbox and getting ready for anything that may move quickly.

Iron

Not yet.  Small design-proto shop.  However, products may involve networked devices using 802.11ah or 802.11g standard.  Plant automation...

Iron

Yes - large area applications

Iron

I'm primarily software, some embedded in past - today just looking just for general information

Nope - not doing any large area apps
