Thank you Fanny and Alex.

Iron

No. I have not use ZigBee. I may use it in the furure.

Iron

Hello from San Jose, CA

HW R&D

Iron

Thank you Fanny and Alex

Good to know about ZigBee, 

Hearing Fanny say that it is about 10 years from being ready, I think that I will probably steer clear of ZigBee until they have some more time to work out the kinks.  Thank you again Fanny and Alex.  Another great presentation.

Iron

Major concerns with this would be security and continuous connectivity without  interuption or lost packets.

Iron

Not using ZigBee now, and not sure of plans to use it yet.  Want to learn more about it before making decisions.

Iron

Primarily hardware, but starting to branch into software now. 

Iron

Thanks for another interesting lesson.

Iron

ALEX, SORRY FOR CALLING YOU MAX YESTERDAY!

Iron

Fanny, very interesting.  Max, you helped bring out some good information from Fanny.  Thanks to both!

Iron

Have not used ZigBie.

Iron

Networking/Security.

Iron

Zigby use question: Not presently using, exploring future use in local control.

Iron

My interest and invovlement is Primarily HW.

Iron

audio cut out at the end

restarting

 

Picking up another one a bit after the fact

Jury duty yesterday. Better late than never.

Iron

Thanks Fanny. I just listened this session about Zigbee...

Iron

Thank you Fanny and Alex. This session provided much needed basics of zigbee and bluetooth. the discussion on RFID was enough to make some basic design choices.

Iron

@fanny, a question, how does one zigbee device become the coordinator? predetermined or some kind of arbitration?

Iron

Alex, thanks for the links

Iron

good session, thanks

 

Iron

Thanks for a great session!

@Alex - Thanks for the URLs.

Iron

Yes, Fanny noted yesterday that 802.11 has features that attempt to resolve those issues but nothing does completely.

Platinum

Alex - if we all get Starbucks cards, can you send mine to Fanny, please?

looks like the archive for me again today.

Iron

Thanks, Alex - lots to look at there.   (and fwiw, I remember Digi-Key from way back - I think late '70s or early '80s)

Thank you - certainly stimulating discussion. I have learned a lot over the course of these sessions and the chat!

Platinum

Thanks Alex, and everyone else.

Iron

Thank you Fanny. You must be tired of so much drawn energy.

Iron

Collision avoidance for ?  (6LowPAN?)

It's the same protocol ... 802.11.4

 

Thank you Fanny!   see you tomorrow (in the audio sense of seeing...   :)

hmmm....  baby monitor as streaming audio - sounds like there's a product there....  practically everyone has wifi in their home now...

FANNY:I What are the qualifications required to be part of an IEEE task force? Are these, volunteer positions?

Iron

We talked yesterday about collision avoidance and the issues that accompany that method that have not been resolved very well...

Platinum

re interference - perhaps baby monitors need to become streaming audio over wifi..    :)

I'm looking for very low-cost Ethernet (wired or Wi-Fi) to consumer IR -- either SOC or boards - if anyone has a suggestion, please mention here or email me alan at ajw dot com - thanks!

Containers are an issue.  Passive tags have other issues as well that are related to packaging.

Blogger

Why would I implement IP over Zigbee rather than just use 6LowPAN?

 

re low power Wi-Fi and interference - yes - this would take care of the interference issues since Wi-fi has collision avoidance mechanism.  Though in the 2.4 GHz band, there are a lot of devices that will just transmitt (e.g. analog phones and baby monitors), so you cannot win...

Blogger

ZigBee now does support IP.  We will cover this tomorrow in the context of SEP 2

Blogger

re low-power Wi-Fi instead of ZigBee, BT -- would that simplify rf interference issues?

There is serious investment into NFC, but i wonder about alternaive radio technologies and whether something better than 13 MHz will eventually take over.  The software stack for NFC will likely be a good investment for the long term.

Blogger

Did I hear you say that TCP/IP is now available on Zigbee ?

Iron

CONTANINERS: another point of concern is for non-uniform cargo. metal based packages/pallets will compromize the reliability of using radio readers, will it not?

Iron

re ZigBee and Bluetooth vs. low power Wi-Fi - there are a few low-power Wi-Fi solutions and they woudl also need to support meshing (802.11s) to be able to replace ZigBee and Bluetooth.  In principle, Wi-Fi can achieve the same power consumption as ZigBee or Bluetooth if you slow down the data rate and lower the TX power.  It's comparable radio technology.

Blogger

@apdobaj - Friis eqn - but use 3.5 for industrial/commercial environments, not 2.

Iron

Is the audio quality of BT streaming better than BT ? (i.e. latest mobile feature boasts audio streaming for mp3's, not just phone calls)

Iron

What do you think on market/consumer adaptability of NFC within next 5 years

Iron

regarding containers - right - you can't read the tags through steel.  You can read pallets and youwould need to open the container and beam readers via opening to target the tags.

Blogger

FANNY: is anyone using super caps to power the low power radio chips?

Iron

how does Bluetooth or Zigbee compare with just using low-power Wi-Fi ?

I find Zigbee can only transmit 100 bytes.  Will this change ?

Iron

what's the best standard for determining relative distance using RSSI?

Iron

DUST is proprietary and claims to be lower power than ZigBee.

Blogger

Bluetooth 4.0 is backwards compatible with older protocols.

Blogger

FANNY: is Freescale using ZigBee in their MPUs?

Iron

What do you think on market/consumer adaptability of NFC within next 5 years

Iron

Fanny:

How does Zigbee compare to the wireless network by DUST Technology?

Iron

I can answer quesitons on specific vendors only privately via email.

Blogger

Fanny,

if the MacAir uses Bluetooth 4.0 is there any backwards compatibility issues with older Bluetooth devices?

Iron

development tools for ZigBee depend onthe microprocessor platform being used.

Blogger

Any vendors with turnkey Zigbee packages?

Iron

Bluetooth 3.0 has the same reach as Wi-Fi when operating on the Wi-Fi radio... less than 200 feet for all practical purposes though marketing people will claim higher distances that may be achievable under special conditions (e.g. open field).

Blogger

FANNY: Is Bluetooth appropriate for wireless in-vehicle automotive networking of personal devices, not streaming multimedia?

Iron

ZigBee and Bluetooth have the same security characteristics AES-128

Blogger

FANNY: I always head/read that bluetooth on smart phones have a range of 10 meters. also, in slide 16 v3.0 has no reach distance.

Iron

Regarding MIMO and multipath, you can also have multiple streams via line of site with no mulitpath if your antennas are cross polarized (i.e. orthoganal with respect to one another).  There are other technues of decorrelating streams, for example Alamouti coding whereby the symbols are time offset.

Blogger

Does Zigbee have better security characteristics then Bluetooth?

Thanks - you actually answered my question further into the presentation. Looking forward to tomorrow's session!

Platinum

but for 802.11ac, do you see analog challenges?

 

Iron

FANNY: can you please elaborate on a comment you made to Alex of "readind through containers". As far as I know, containers are mostly made of steel, and thus will reflect fast radio waves. Aren't they?

Iron

@Fanny:
1. What tools are needed for development of a ZigBee product?
2. How expensive are these development tools?
3. How do ZibBee and Bluetooth compare in comm range?

Iron

802.11ac is likely to be the next generation Wi-Fi; 802.11ad will depend on price-performance, not clear yet

Blogger

Thank you Fanny and Alex (and Digi-Key) - these are wonderful reviews - very helpful!

what's the best standard for determining relative distance using RSSI?

 

Iron

Fanny,
You have made the point several times that multi-path is required for MIMO to work.  While I agree that overcoming the problems that multi-path causes is one of the strengths of MIMO, I don't understand multi-path being a requirement.  Two transmitters at one place, connected to two separate receivers at another, each pair using a separate multi-path free RF path will provide twice the throughput of one alone.  By extension, any symmetrical MIMO (2x2, 3x3, 4x4).  For a single receiver receiving packets from two transmitters (non-symmetric MIMO, 3x2, 3x4, etc., and cross channel paths) the packets have to arrive at slightly different times, either caused by different RF path lengths (multi-path) or by delaying one of the transmitters.  Perhaps the distinction should be made between multi-path and multiple RF paths.

Iron

thanks everybody for making todays class a great sucess

Platinum

Fanny, can you talk about 802.11ac/ad market, is it going to be huge like 802.11n ?

Iron

what are the pricing comparison Zigbee and Wi-fi

 

Wi-fi is generally more cost-effective than ZigBee due to volumes produced

Blogger

Thanks for the info.

Hear y'all tomorrow

Iron

Thanks fanny for this informative section

Platinum

I could not get the audio to work when using Internet Explorer. When I switched to Google Chrome it worked great. You may want to share that info with others having audio issues.

Iron

see your tomorrow. cheers

Platinum

Fanny, can you talk about 802.11ac/ad market, is it going to be huge like 802.11n ?

Iron

thank you Fanny and Alex

Iron

wifi chip cost vs zigbee?

 

Iron

@krhohio - I understand it's still under design - it's a capacitive-coupled touch smart card tech. Who knows if it will be adopted by some standards committee ??

Iron

Thank you Fanny..and thank you Alex and Digikey for these very informative sessions.

 

Iron

Fanny is dandy.  Thank you for your time in expressing your technical expertise.

 

Iron

Fanny, can you compare Zigbee to the wireless network by DUST Technology?

Iron

Thank you for today's presentation Fanny

Iron

Thanks Fanny. Apprecite

Iron

Well done Fanny, you really know your stuff.

Great presentation, Fanny and Alex - very informative!

Platinum

another great presentation Fanny. thanks everyone.

Iron

Thanks!! Fanny, enjoyed the presentation.

Platinum

Great presentation - Thanks!

 

anyone has these classrooms in mp3 files ?

Iron

Question for Fanny: Can she compare some of the ZigBee-like proprietary standards?

Iron

how 802.11 can be used in smart grid applications, can you figure out few

Platinum

@JSP: Do you have a good URL for TouchCard info?

Iron

Do you have any experience with the Synapse Wireless line of modules?

Iron

* app * called Key Ring...

@luizcosta - super caps need to be charged, and it is not quite easy

Iron

@caa028 though you were serious, thanks though!.. it must be a commercial for tape.

Iron

Android (and iPhone, presumably) called Key Ring - reads store affinity cards (e.g. the bar code tags to attach to key rings) - works mostly; hard to scan sometimes, and the app is much slower than it originally was

my sister-in-law has a smartphone and to use her reward cards she uses them from her phone, think it is a barcode

Platinum

NFC is neither zigbee or bluetooth

Iron

SUPER CAPS ARE THE FUTURE REPLACEMENT FOR BATTERIES.

Iron

@Luizcosta - near field communications is a fallout of Maxwell's equations (near vs. far electromagnetic field). NFC is standard that uses those fields.

Iron

@ raghu - this "chart" explanis it about duct tape: http://www.cyclelicio.us/wp-content/uploads/2011/11/flowchart-500x372.jpg

Iron

Alex, are you sure that is not a barcode on the smartphone?  I have seen at Starbucks people who have their Gold Cards on their phones hold it up to the bar code reader that is used to read barcodes on products.

Blogger

@alex - I thought the boarding pass readers were actually reading the bar code from the screen the same as it would from paper? what do you think?

Iron

got some idea of  zigbee need to play with those. I will try to find the xbee @ didgkey if you have maore info please send me the link

thanks

Iron

i just saw a tv ad here someone used their phone as the boarding pass, very interesting

Platinum

NFC - near field communication is a generic name, right? Zigbee or bluetooth.

Iron

what is ducktape about? does it really block RF? no right?

Iron

@garysxt - good point...

What are Fanny and Alex talking about "reading through" a metal container?

Iron

Just posted again, but it never showed.  Something needs a little WD-40 or Duct Tape.

Iron

@Alanjay - Bar codes easily counterfeited

Iron

NFC is zigbee or bluetooth based data transfer

Platinum

You can buy a wallet made from Duck-tape (talk about ugly).  I wonder if the metal particles giving the tape it's distinctive color would block the RF?

Iron

@trottinc: My Chrome Browser was doing the same "buffering" yesterday but it's fine today. Make sure that your IT dept is not blocking "blogtalkradio.com" or "llnwd.net".

Iron

@Alex - I saw a VERY ugly mesh vallet (made out of metal mesh)... if they hide foil or mesh under leather, it would be much better

Iron

can you simply put a sheet of aluminum foil in your wallet to protect the contents

Iron

wouldn't simple bar-codes work better than NFC for reading at a distance?   (factory pallets, etc)

Alex, RFID is used specifically for short distance (passive tag).  This allows you to locate the tag.

Blogger

yes I thought so, @caa028.  I would pay more though for a wallet that wore better.

Blogger

a pickpocket sniffing smart credit/ATM cards - it is real

Iron

@Alex - the only reason they use foil vs mesh - is to lower cost...

Iron

can zigbee be used or is it used in credit cards that have the embedded chips

Platinum

re security - was an amusing NCIS recently - a pickpocket sniffing smart credit/ATM cards

BLUETOOTH in smartphones can be class 1 or 2?

 

Iron

What about reading NFC at a distance like using a Pringles can antenna on a RFID reader to read folks RFID chips from a block away?

Iron

I just saw a stainless steel wallet.

Blogger

low power, 10meters outof line, medium speed communication might be useful for most of the domestic applications

Iron

NFC is stillborn. A TouchCard can transfer Gbps and do biometrics on me before transacting without spoofing concerns.

Iron

as well as power consumption.

Iron

presentation has been stuck on buffering for over 2 mins, any status? 

Iron

so many differences between each but so many similarities.

Iron

Good question Alex. 

Blogger

is there any comparison for BT vs Zigbee on cost, range, speed?

 

Iron

@jl @Alex - Almost all of my postings show up fine.  The symptom shows only every now and then.  I have NO IS server between my workstation and the Internet, so I think the problem may be localized to Alex's end.

Iron

low power is key for battery operation and life...

Iron

Bluetooth 4, new additions

Platinum

OPEN QUESTION: itsn't bluetooth only good on direct line of sight?

Iron

low power is better for my designs always trying to keep power low

Platinum

BT 4 vs Zigbee as far as power ?

Iron

With a host of competitive technologies on the market, can you sum up the compelling factors for choosing ZigBee for a short range wireless application rather than some other scheme?

Platinum

I have not used Zigbee yet but I am looking to try in the future.

Uses could include power monitoring, sensor networks, simple control.

Iron

Infrared - where does it stand?

Iron

for high speed data transfer, which one is prefered zigbee or Bluetooth 3

Platinum

@alex @ran - my first response to the zigbee question never made it to the board listing here. the 2nd one cam thru

Iron

Have used but never concern about security. I think it's still not widely used as to worry about hackers...

Iron

How expensive is zigbee vs bluetooth?  Codespace for stack, how powerful a microcontroller, etc.

cheap cost and implimentation.

Iron

had an old patent idea for a smart power meter that used different technology maybe i will try it using zigbee

Platinum

i am not a zigbee user, attending webinar for general wireless knowledge only.

Iron

same here sometimes my post are not showing up..just lost in the world wide web..

Iron

Zigbee is being used out of the box ,as products come with items. No build it yourself planned at this time.

 

Iron
Considering for environmental chamber sensor connection in distant future.
Iron

After all these different wireless topologies, does Infrared still hold any significance? what is its adv over others? 

Iron

never used zigbee or bluetooth, don't plan to

Iron

@Alex - I've answered most of your questions, but occasionally my postings don't show up.  I wonder if your server is dropping some of the postings?  This is not a new problem.  I've noticed it during webinars past and have posted the observation previously.  This might be why you are not seeing as many responses to your questions as you are expecting.

Iron

Bluettoth 3 can attain a very high rate of data transfer speed

Platinum

there are some designs i would like to try using zigbee

Platinum

Are there now vendors offering packaged turnkey zigbee solutions for home and industrial environments?

Iron

Have never used it. But would like to tryout for remote data sensing and collection.

Iron

I have not yet implemented ZigBee, but it remains an option for  future applications.

Never used, plan to use it for smart transmiters comuncation.

Iron

have not used zigbee

may use in near future involving FTTH and smart-grid

Iron

have not used but looking at as an example for future things.

Iron

Is BT streaming decent audio quality ? (i.e. latest mobile audio hdw)

Iron

No plans for Bluetooth - don't need 1MBps+ for factory apps.

Iron

Not designing things with Bluetooth

Iron

I have not used these technologies yet

Iron

Looking at all wireless protocol options to see what would be the best for our next design.  Required for handheld device for industrial controls.

Iron

I'm not using it because of the high operating overhead

 

Iron

what's the best protocol for location based applications using RSSI?

Iron

Planning to use ZigBee for distributed sensing & control.

Iron

we may have interest in zigbee, no plans yet.

Iron

Not currently using, but interested in potential future sensor/device connectivity

Iron

What do you consider to be the advantages of Zigbee over Z-wave?

 

Iron

haven't used zigbee.  No plans to

Iron

Have not used ZigBee. Evaluating now for security application.

Iron

have not used zigbee, plan to use in an evalution or lab research within the next 6 months

Iron

Only see ZigBee in Digikey.

No plans for use.

Iron

General interest only as part of this series

Iron

I thought bluetooth range was around 10ft.

 

Iron

Haven't used zigbee, no plans.

Iron

from slide 5, i looked at googlepowermeter and ms hohm.. everything seems to be about to shut down.. didnt read the reason though!

Iron

i think she did say 2013 or at least that's what i head

Platinum

what is the max range of bluetooth?

Iron

cost is a concern in everything...

Iron

i thought i heard 2013, but that could be 2003

Iron

think she meant 2003

Platinum

never used the blueline power meters.

Iron

how far is the communication distance for that bluline?

Iron

Anybody usedone of those blueline wireless powermeter in the presentation? 

Iron

Alex, what are the concerns in piconet

Platinum

The notes near the bottom of slide 11 show the calculation of the channel frequency f given the channel number k, confirming the 1 MHz channel spacing.

Iron

in scatternet, whether any chance for overlapping

Platinum

what is the maximum board range of zigbee?

Iron

Alex, what are the concerns in piconet

Platinum

@farebrog, Fanny is answering your question now.

Blogger

Interesting explanation on need for and limitations of frequency hopping with blue tooth.

Platinum

QUALITY OF SERVICE: it has been marginal at best, but helpful for voice communications.

Iron

Fanny, slide 11 says RF channels are 1MHz apart, should this be 5MHz?

Iron

Dataflow, transmitting overhead, encryption..

Iron

ANSWER:  TYPE IN YOUR QUESTIONS FOR FANNY, SO I CAN ASK HER ABOUT THEM DURING OUR DISCUSS AFTER HER PPT.

Blogger

 security and data rate

Iron

A. Quality - minimum loss of data/control

B. Data Rate/throughput

security, reliability, cost

Iron

The security is built into the actual data being transferred

Iron

concerns - security, 

Iron

SECURITY, RELIABILITY, AND DEPENDABILITY

Iron

Power usage, reliability

Iron

When implementing a wireless network - reliability is huge.

 

Platinum

interference and reliability

Iron

Concern: power (battery life of remote sensor)

interferance with numerous transmitters

Iron

concerns - security, data rate, quality and reliability in a harsh environment (factory floor)

Iron

current interest is cost - low data rates, medium-level-security

security is important in utility industry!

Iron

in most cases security and performance

Platinum

I think security is the major concern

Platinum

quick response and range

Iron

General concern is performance.

Blogger

no need to run cables all over the factory floor

Iron

ease of implementation

Iron

major concern is power usage

Iron

interference and reliability of connections

Iron

Regarding UWB: nevertheless, it would seem that 10% of 460Mbps is quite impressive.

Iron

Cost, performance.

 

Iron

ANSWER: WHAT IS YOU MAJOR CONCERN IN IMPLEMENTING A WIRELESS NETWORK:  SECURITY, DATA RATE (aka performance), WHAT ELSE? 

Blogger

Blogger

IPv6 !?!?   that's a surprise

used it some times back

Platinum

never used zigbee, I would li,ket o try it

 

Iron

think my power company may use zigbee for meter readings

Platinum

love the smart metering application - power management is becoming more important to the consumer

Platinum

Have used in a past project.  I am looking at some projects using Zigbee as well.

Blogger

a recent project (not mine) with power meters:

http://www.howmuchsnow.com/arduino/gridinsight/

Iron

Have used Zigbee, will use Zigbee.  Easy to impliment!

When the Siemens guys started talking about eliminating a lot of wiring using this technology my electrical contractor said "Let's not get carried away."

Blogger

We've looked at ZigBee but never used it

Iron

have not used it; would be interested in smarthome applications   (currently using X-10 in areas; semi-successfully)   especially interested in using for home theater controls

ZigBee, no not so far.

Iron

audio issue has been resolved...not currently using Zigbee but interested inlearning about it

Platinum

zigbee is an interesting concept. would plan to use it

Iron

Plan on using if it fits the application.

Iron

Planning to use 802.15.4, but probably not Zigbee because of cost ($3400 I think?).  Maybe 6LowPAN ?

my company sells Zigbee chipsets and I do applications engineering.

Iron

investigation, not yet using.

Iron

Not using ZigBee currently. No immediate plans

Haven't used it but could down the road

Not use Zigbee but use own wireless protacall for lighting controls

No need for ZigBee in my robotic applications

Iron

Yes, low data rate and very fussy in positioning in factory/commercial environments.

Iron

Is audio dropping out frequently for anyone else?

Iron

Not using ZigBee. May use it in future.

Iron

Currently using Synapse 802.15 (non Zigbee complient) radios.

Iron

ANSWER: HAVE YOU USED ZigBee or ARE YOU PLANNING TO USE IT NEXT 12 to 24 MONTHS?

Blogger

We use Zigbee in our plants to gather data wirelessly

Iron

@Alex - Never knew enough about it, so didn't use it, but would like to have used it.  Always heard it was very difficult to use.

Iron

Yes, We have implementations of ZigBee, May use it for future products

Iron

have not used Zigbee and looking forward to use in future.

Iron

Tried to use it, but very difficult to implement.  Python was a real black hole of wasted time for me.

Iron

Hove not used yet. I am planning to use it in the next year.

Iron

Have not used it yet, but will in the future

Iron

planning to use, once I understand the basics of it

Iron

not currently using or planning to use, but that may change

Iron

Alex, Fanny - if not covered later:  licensing issues/costs compared to Bluetooth

is it a chance for Zigbee to affect by magnetic fields

Platinum

If the APs and sensor devices are stationary in a factory, is a centrally arbitrated (scheduled) system more efficient than ad-hoc mesh network overall ?

Iron

is zigbee required more power to work

Platinum

Q: coordinator - only one or more than one?

Iron

In 2004 Siemens was doing Zigbee fairly extensively. 

Blogger

Working on intergration and deployment therefor both hardware and software.

Iron

Platinum

Alex, great comment to start yesterdays session re. it's not free, but it's at no cost to you.

Iron

Good afternoon everyone.

 

Iron

Hi Alex, Hello Fanny! looking forward to another great presentation on wireless and zigbee.

Iron

hello everyone, good to see all of you here...

Iron

I'm really looking forward to learning about wireless protocols for sensors!

Platinum

Okay, this is the first session in weeks that I'm here before it starts.  Let's see if I don't have to refresh every five minutes.  I love an IT department that knows what it's doing.  Now if I can only find one....

Platinum

hi alex, hi fanny. hello everyone

Iron

Good morning Alex, or is it good afternoon for you on the east coast?

Iron

Good afternoon folks.

Iron

good afternoon everyone

Iron

@Alexander Wolfe: If I might make a suggestion re "Interruptions": I don't know how you get Fanny's audio stream, but if you both could keep a "private communication channel" open via some IM software like skype, you could "inaudibly" ping the lecturer to stop talking for your comments and questions. Then, ideally, lecturer would pause, you could talk, lecturer would respond and the audience would be amazed by the smooooooth flow.
