Hello from Gold River.

Iron

Thanks Charles. good presentation.

Iron

Not using PAN implementations in IoT.

Not using RFID as part of an IoT implementation.

I picture a scenario where an FCS equipped and trained army gets routed because the other side has a jammer.

 

Iron

Excellent session, thanks

Iron

?? Charles Can you recomend further bibliography ?

Iron

can you recommend a good practical reference for determining location by signal strength?

Iron

every time I swipe a credit card I wonder why that ecosystem hasn't taken off...

Iron

NFC - ha ha ha - I wish I knew that answer! Handset industry never fails to surprise me.

 

Iron

Goodnight everyone, goodbye!

Iron

to your point, will NFC become commonplace in mobile devices anytime soon? if so, which standard?

Iron

gotcha. multipath not an issue in my application, but environmental certainly.

Iron

Environmental attenuation and multipath

Iron

any white papers you can recommend? "issues with propagation" are you referring to interference (the band is crowded) or environmental attenuation or what?

Iron

ZigBee Telecom protocol is kind of out there, but you see competition with other near-field communications. Secret would be to get Apple and Samsung (and others) to agree to a single near-field protocol.  When I develop something now to tie to cell, I use wifi, BT, or USB

 

Iron

I am taking a look to ISM MRF49XA 

Iron

Location using signal strength and triangulation is built into 802.15.4 and is my favorite. And it works. But it is 2.4G so has issues with propogation

 

Iron

and wondering if you can speak about adoption by the cell phone industry - support for wifi and BT is solid, what about zigbee and others?

Iron

YES, FCS structure needs self-healing and re-configuring mesh networks. ZigBee can do that BUT since it uses the same algorithm as phone system is requires a reconfig at times.  Shades of MS Windows...

 

Iron

?? Yeah, I see. I see that some tracking collars communicate with satellites but not sure how.

Platinum

what in your view is the best protocol for location? in other words, using signal strength to locate something.

Iron

Tracking wildlife - I take it you are familiar with the existing hardware and protocols. I have experimented with 802.15.4 with triangulation at 900Mhz. Requires having active fixed nodes.  Otherwise you are back in the wild with yagis (and typically grad students)

 

Iron

Thanks Charles & lauren

Iron

?? What wireless method would be useful for tracking wildlife from perhaps a mile away, possibly not line of sight?

Platinum

yes any PN recomendation ?

 

Iron

Thanks Charles and Lauren.  

Iron

FCS architecture, as envisioned, included adhoc networks among stationary and moving nodes that might be intermittently in range, including distributed sensors in the battlefield.  Quite a challenging problem.

Iron

50m, on-off? There are a number of ISM chips and even at least one uC with RF built in available out there.  I would still add some kind of minimal ID with FSK instead of carrier.

Iron

thanks Charles, see all tomorrow.

Iron

The slide deck will get sent to Design News later today so should be up early tomorrow.

Iron

Started backwards - @wahaufler - great question! I was involved in FCS a long time ago and yes this does look familiar. 10-20 years ago, I would say military would drive industry; but with today's COTS programs I see it going as you say.  And I do think that IoT will have definite military logistics applications as well as perhaps for c4

Iron

?? Having studied a bit of what was once called "Future Combat Systems" (FCS), there seems to be a lot of overlap, or a large potential application of IoT to FCS.  How do you see the military's use of IoT.  Will defense development drive commercial development of this tech, or vice-versa?  (I suspect the latter)  Thanks

Iron

?? When will you put the Slide Deck on line for tomorrow's sesion?

?? Charles I wonder what is the lowest cost recomendation for a point to point wireless link 50 meters, on-off application, one way ? 

Iron

@Zwilrich - thanks for the suggestion!

Thanks for the information!

Thanks Charles for the clearity of the information you elaborate on. Great seminar!

Lauren, thanks.

 

Iron

It makes it much easier for Charles to find your questions if you put two question marks (??) at the start of the question.

Iron

Thank you, Charles and Lauren!

Thanks to both of u as well
Iron

Thanks all - Grabbing a coffee and will be right back to answer questions!

Iron

Thanks A Lot, great presentation. See you tomorrow

Iron

Excellent. Thank you, Charles!

Iron

Okay, thanks for the interesting talk.

Iron

Thanks Chaeles and Lauren. You have a great presentation.

Iron

Thank you Charles and Lauren. Have a great day.

 

Iron

Thank you Charles, Lauren, Design News and Digikey

Iron

Charles I wonder what is the lowest cost recomendation for a point to point wireless link 50 meters, on-off application ? 

Iron

Thank you Charles, Design News, and Digi-Key.

Platinum

Thank you Charles, Lauren and everybody!!!

Looking forward to tomorrows lecture, thanks Charles & Lauren

Iron
RS485 and 422 is still heavy use if we can string the wires.

USB, BaseT and RS485.  No immediate plans for CAN.

Iron

easy solution to bad tomato, eat the tomato and no need for IoT on food

Iron

Wired, believe or not we still use RS485

Iron

Using CAN, USB, wireless...

Iron

Sorry work got in the way, PAN nothing particular at this time still gathering data.

 

Iron

Have not used wireless much, studying BaseT.

Iron

The wired connectivity I have used is using Power Line Comunications. There are lots of standard protocols but we used a proprietary protocol.

Iron

we use CAN for mobile applications, tank top mounted liquid level transmitters to a display

Iron

Only USB interconnect design work at the moment.

Iron

I've work with CANBus protocol in the past.

Yes, we have automotive products that we develop.  So, we have some CAN based applications.

 

Iron

Currently using CAN and USB

Not looking at any wired solution for IoT at the moment.

Iron

The question was: Is anyone looking at wired links in IoT?

Platinum

I've done wireless smoke detectors running at 915MHz (states, and 868 Europe).  Wireless HVAC controls running at 915.  All proprietary protocols.

Iron

Yes, have you heard about Insteon ?  I am developing for Insteon devices.

Iron

Not using PAN presently.

Iron

Can you comment on using 5GHz for Wifi?

Iron
Experimenting with BTLE
Iron

Have not used PAN.

Iron

No used PAN in my job. Just uses Bluetooth in cell phone for fan.

Iron

None at present - looked into Zigbee but seemed lacking.

Looking at Microchip's proprietary system for a simple wireless control system.

Iron

Thinking about for any future project

Iron

Bluetooth now, Zigbee for future

Iron

Yes, currently using Bluetooth.

Yes. We have used Bluetooth and MiFi for agricultural and water quality applications.

Iron

Using ZigBee (but don't like it), but also using WiFi for reliability.

Iron

I believe it was Thursday of the Zigbee class I decided to go wifi.

 FrankMcCarthy @ Top of the page, click on Curriculum Calendar and use Atchive.

Iron

The question was: What PAN implementations, if any, are you currently using or considering?

Platinum

Can you provide the URL for these earlier classes?

 

RFID on a project a couple years ago.

 

RFID block detection on the toy train set, does that count?  :)

No, I'm not using RFID.

Iron

not using RFID in my job

I used RFID 5 years ago while working for a defense contractor to track items in the logistics process.

Iron

Not using RFID currently, but I used to work on making RFID reader infrastructure

 

Iron

Have  used RFID on networked devices.

Iron

No RFID in our current products. We built IP camera.

Iron

I've done RFID design for security/access systems, but not doing any currently.

Iron

Not using RFID at this time

Yes, for a handheld control device.

 

Iron

No RFID yet but considering

Iron

Not using RFID at this time.

Iron

Not at this time, but clients may implement this at some point in the future.

Iron

No have not used RFID at this time.

Iron

I am not using RFID tags at the moment.

Iron

Not currently using RFID but want to use it for my Great Dane dog door

Platinum

no RFID is current or future products

Iron

The question was: Are any of you using RFID as part of an IoT implementation?

Platinum

Wouldn't it be best describe as an "INTRA-net of Things" to reduce confusion?

@Genius  Yes, you're right, the "layers" play a huge role.  But I just worry about passing 1's and 0's between the different "things" and then deal with 'em at the destination for the results.  Yes, HTML, but also oLED's, LED's, computers or a MCU interface to a motor driver, for example.   We're just slapping "building blocks" together and using IoT to interpret, manipulate and utilize the 1's and 0's.   I'm so glad I wasn't born in the ol' west times.   :)   I probably would've tried to IoT the telegraph.  :)

Got the slides.  Thank you.

LOG JAM CLEARED!!! Expect the slides very soon. (whew!)

 

Iron

@JoeFromOzarks: I have spoken the words "if I only had the time to do xxxx" all to often.  In the part of the networking I would agree that the wired & wireless Ethernet has been the most developed, and work especially well to transmit HTML.  I'm not sure about Zigbee and if it has capability to support HTML.  Canbus is currently developing HTML and video/audio streaming for use in the automotive entertainment systems.  Essentially there is a "layer" model of communications and at some point there needs to be an IoT "application layer" that can be transmitted over the various "physical layers" of Ethernet, Zigbee, canbus, NFC, etc. that can link multiple devices across multiple network medias.  Just my $.02

Iron

Good afternoon.  Another beautiful Fall day in Kansas.

Hello from sunny Michigan.

Iron

@Genius  That's what I've been toying with, "stuff" or "things."   Most of what has taken six months to slap together, a "normal" tinkerer probably would've slapped together in a month of weekends.  I'm disabled and have many high pain days (today is a 6/10) so networking everything together is a project to keep my brain (and body) from turning into jello.  :)  All of this stuff was tied together via Zigbee and was comparable to a tabletop full of "TV remotes" which everyone knows is frustration+1.   When I made the decision to switch to wired and wireless ethernet it was simply amazing how seamless connecting everything became.   I wish my electric utility would place a smart-meter, but they won't. (sigh)   :)

PLEASE NOTE: The slides are delayed by issues on the presenter's (my) side.  Please stand by - working to resolve this by class time!!!
THANKS!!!

Iron

When will be the materials ready for download?

Iron

Greetings,

@Wonohkim & JoeFromOzarks: I would have to agree that the IoT is a network of devices.  For the home, it would be different things from different vendors such as normally automated things such as the sprinkler systems, smart heating systems (AKA "Nest"), your power and water meters (Smartgrid), and other things that you might not even consider such as my washer/dryer set that has diagnostic capability to the manufacturer LG (it uses an analog modem that you hold up to the handset).  Then think of your car- you have the engine ECU, the transmission ECU, the entertainment system w/ MP3 storage, the navigational system with maps, etc.  Eventually this will all be networked into a group of devices on our own personal "internets" or networks for us to monitor and control.  Think personal SCADA.  Lots of devices and lots of data.

Hello from Binghamton, NY

Iron

IEEE is creating a new group devoted to IoT.

http://theinstitute.ieee.org/technology-focus/technology-topic/exploring-the-impact-of-the-internet-of-things

Iron

@mharkins Data over TCPIP, simply using the regular ol' wireless bases, routers, access points.  There are manufacturers of TTL-Serial to ethernet interfaces both wired and wireless, not too expensive and easy to connect.  Simplifies pushing data from MCU's or RS232/485 (etc.) on to the network.   (I feel as if this is an incomplete and fuzzy answer.)   :)   My point is, it's becoming easier and cheaper to talk to ethernet networks.

@JoeFromOzarks.  Exactly what do you mean by "standard wireless networking" protocols?

Iron

@Wonohkim I've been spending a fair portion of the past six months eliminating proprietary communications (wireless such as Zigbee) and converting to "standard wireless networking" protocols, the eventual goal to communicate everything through a wifi smart phone.  Power use, weather station, HVAC controls, robo-mower (if I can figure out accurate triangulation/trilateration code on MCU's,) security system, security camera's, access control and all other devices around the homestead.  Currently, most everything operates on its own "communications band" and protocol.  Pushing and pulling data across "the Internet" (wifi connectivity) establishes a base for standardization of "Things."    Does this help?

Greetings from sunny Chicago!

Iron

Hello from Waterloo, ON, Canada

@Wonohkim    I don't get out as much as I used to, but seems as though IoT, by definition, is supposed to be broad and abstract, IMHO.  If we break IoT down "Internet" has become slang for "Connectivity" and "Things" (around these parts) = "Stuff."   Connectivity of Stuff.   IoT is a catchier 'phrase' than "CoS."   :)

Hi from Panama City, FL.

Hi from Chihuahua, Mexico

 

Iron

Please join our Digi-Key Continuing Education Center LinkedIn Group at http://linkd.in/yoNGeY

Platinum

I still confused on the definition of IoT. It's too broad and abstract.

First, is it anythings that has ID and can put into internet? Then does it include bar code (without any computing power)?

Next, how about cell phone? The ID and geo-data can be registered into internet and traceable. 

Then, how about the content of facebook? The content has important information (including ID that traceable).

And finally, how about youtube video?

Iron

Much nicer weather today in Aurora, Ontario. I think I'll play tennis tonight.

Iron

The slides will be posted before the class begins.

Platinum

The streaming audio player will appear on this web page when the show starts at 2 PM Eastern time today. Note however that some companies block live audio streams. If when the show starts you don't hear any audio, try refreshing your browser. If that doesn't work, try using Firefox or Google Chrome as your browser. Some users experience audio interruptions with IE. If that doesn't work, the class will be archived immediately following our live taping.

The first Tacoma Narrows Bridge was a Washington State suspension bridge that opened in 1940 and spanned the Tacoma Narrows strait of Puget Sound between Tacoma and the Kitsap Peninsula. It opened to traffic on July 1, 1940, and dramatically collapsed into Puget Sound on November 7, just four months after it opened.
Noting that we now live in an era of “confusion and ill-conceived stuff,” Ammunition design studio founder Robert Brunner, speaking at Gigaom Roadmap, said that by adding connectivity to everything and its mother, we aren't necessarily doing ourselves any favors, with many ‘things’ just fine in their unconnected state.
