Note:  Thanks for archiving these sessions.

Because this is an archived review, I will research the answers to these questions and they then become suggestions for inclusiion to future presentations / slide modifications or additions

Good overview / introduction -- looking forward to learning more ... and about how network formation occurs and is / should be architected in larger *(e.g. multi-floor building) applications

IN RE the previous question - ZigBee compliance (Certification); one would not expect this to include FCC approval, even if the module is a compliant module -- say on - what is the total approval / certification process and is this inclusive in the $5K (to $10k) startup figure mentioned?

ZigBee MODULES (e.g. Jennic) have (or are getting) FCC approval ... what does the approval process look like for chip sets (cost, time, complexity / design other issues)

Looking forward for more lectures

Iron

Re topologies - yes, familiar.

Iron

Great to have access to the recorded sessions!

Iron

Taking the course offline

Iron

I have new X_10. Equipment can it be modified to use zigbee?

Iron

thanks 

A good fast and informative introduction 

I look forward to tommarrow

I appreciate the content though

This one I'm really looking forward to

Picking Up The last course of the year

Better late than never

I'm familiar with star, tree and mesh topologies

Iron

Thanks Charles; very informative lecture

Iron

good to be aboard, finally.

Iron

Thank You, Good info!

Iron

good session, thanks Charles, and Rob

Iron

Thank you all for attending.  There are some questions on routers and profiles that I would prefer to answer as part of the next two days.  I am available at c.j.lord@ieee.org for consultation and training.  Web site not up yet - new company!

See all of you tomorrow!!

Iron

can different profile end device joint in same network with one coorinator?

as they are from different profile it will not communicate with each other but can we use one coordinator for two profile domain?

Thank you very much, Charles and Rob!

Iron

Thank you for session, great information

thanks for being a great host, Rob!

 

Iron
Very good, Thank you.

Thanks Charles.  Range is good to know.

A coordinator can also be a router, yes

Iron

Thanks so much, Charles. Great program. Looking forward to tomorrow.

15.4 and ZigBee can physically address 64K nodes, but practical bandwidth limitations, I would say more than 10K would be difficult.

Iron

Good to hear. Thank you.

Iron

Can a node in Zigbee network perform as a coordinator and a router at the same time? Can a coordinator be designated according to the their appearance time, i.e., the first node in the zigbee network automatically becomes the coordinator?

Iron

High power nodes from Digi and others are still compatible with the 15.4 standard but are not with ZigBee (there is discussion to make them part of Pro)

 

Iron

ZigBee and BT use completely different modulation.  They are not compatable

 

Iron

I'm considering using the XBee Pro 900 line from Digi because they claim over 20 miles line-of-sight (with high-gain antennas). Are their modules part of the standard (as proprietary maybe) or are they something else?

 

Iron

There is not an academic arrangement, but remember the real need for paying the ZigBee Alliance is to register and test a product.  You can download the specs (the "public" specs) for free and you can get free stacks (software, pre-compiled) from the hardware mfrs.  I teach classes and we biuld lots of things.  We just can't sell them as ZigBee

Iron

How long is the range between nodes using ZigBee 9xxMhz?

 

Iron

can different profile end device joint in same network with one coorinator?

as they are from different profile it will not communicate with each other but can we use one coordinator for two profile domain?

 

I would add to the Q&A on what sensors work, you have only to look at bandwidth.  Something that is sending fairly high frequency components may tax the network.  Not just audio - look at seizmic or other waveform sensing - for example a heartbeat.  You can get past this with pre-processing in some cases.  Anything that is fairly static will work great in these networks

Iron

The Hue LED light bulb (Philips) is controlled with ZigBee.  The competing LIFX bulb is controlled using 6LoWPAN.  What are the pros and cons between this two protocols?

Iron

As to range between nodes - the mfrs claim anywhere from 10-50m open space.  There are MANY factors that affect this at 2.4Ghz, including people being around.  10m is very possible, but farther than that, antenna design becomes an issue.  A simple dipole or even a J (most common) may not be enough.

 

Iron

can zigbee use the same radio as BT?

Iron

Regarding what types of sensors applicable for ZigBee, general answser is ALL are! 

Iron

Are there waivers or reduced fee structures for academic/research applications using ZigBee?

Iron

Would you please recommend us link to buy the starter kit?

Iron

Short answer to the aircraft question - yes.  Not ZigBee, but based on the simple star network.

Iron

In implementations using the TI CC25xx SOC solutions sometimes us the RF Microdevices RF6505 front end. I am working on a design now and I need to know if the benefits are worth the cost. Do you have an opinion on this?

Some have asked about having to "go ZigBee" as I call it if you want a simple application.  My answer is "No" - Most apps I have designed are NOT ZigBee

Iron

What type of sensors are applicable to ZigBee and what types are not?

Are there any applications for aircraft ?

Iron

Good to hear that many of you have a familiarity with topologies.  We will review for those of you who do not

Many asked about BT low energy - it is an attempt to bring BT to the 15.4 level of power consumption.  It is, however, still a less energy efficient transmission protocol.  15.4 is still better for battery life.  BTLE is better if you need any more bandwidth - we are limited to 10-30K in 15.4

Iron

Second question is, what advantages does RF4CE have over BTLE?  ZigBee and BLE datarates and power profiles seem very similar 

Do I need pay for a smaill Zigbee device if I just apply it on a small room space for very low data speed sensor?

Iron

what is the physical and practical range limits between nodes?

 

Iron

Can we have a starter kit for Zigbee ??

 

Iron

Thanks, nice overview.

Iron

Zigbee seems to have some overlap with Bluetooth LE, can you comment on their applications and the cost of implementing either one of them?

Iron

"Supports Large Networks (2^16)", does this statement mean that ZigBee can sustain up to 65535 nodes in the network? 

Hi everyone - had to get a sip of coffee - and ready to answer some questions!

 

Iron

Can you move from a simple network to a mesh network by adding/replacing a layer?

 

Great info. Whatis the range for ZeeBee devices?

Can Zigbee support low-latency applications?

Iron

Thank you Rob & Charles

Iron

Great coverage. Thank you.

Iron

@charles how does BTLE compare to zigbee - where does it fit into the standard and how does it compare in terms of power consumption?

Iron

Can you use a profile without registering your product as a zigbee device ?

Very Interesting, looking foward to learn more about this!

 

Iron

Looking forward to the rest of the week.

 

Iron

Thank you for an excellent overview...Looking forward to the following lectures!

is there difference between zigbee and sensor area networks?

 

Iron

Has energy harvesting ever been discussed as a part of the ZigBee or 15.4 standards?

Iron

Great presentation, Thanks

Iron

what is the physical range constraint between nodes?

Iron

Thanks Charles, Rob, & Digi-Key!

Iron
Supports Large Networks (2^16 devices): Does this mean that ZigBee can sustain 65k nodes?
 

What does the "ZigBee" name mean?

Is it a acronym for something?

Iron

As always, the devil's in the details. Thanks for the entry level.

Thanks  Charles and Rob.

 

Iron

Thanks.  Informative Lecture.

 

Iron

That was great.  Lots of information in a short window.  Looking forward to the rest of the week.
