Good presentation on Zigbee vs. MiWi

Iron

Fantastic lecture.  Thanks, Fred.

Iron

Still ... lots to learn about MiWi

Not yet for development with MRF24J40-based radio module

ZigBee is under consideration

A bit late, but here.

Iron

Thank you for a great lecture and have a great day

Iron

THankd to everyone that attended today.

"See" you tomorrow.

Have I missed anyone?

Blogger

@Fred - OK Thanks.  If you can really get 4000' with the B modules I might be able to do P2P. I only need about 1000' and could 915MHz which should help.

Iron

Thanks again, Fred.  Great class. Over and out.

Gold

@78RPM

Normally not.  Remember, the radio is radiating in a pattern not a beam.

Blogger

@78RPMg

Sub GHz does a better job around plants and walls than does 2.4GHz.  Depending on the site, sub GHz radios are usually the winners in the range war.  It all boils down to the antenna and the terrain.

Blogger

@garysxt

Much more complex.  Remember, the stacks are scalable.  So, there is no exact byte count.  You can get estimates of ROM usage in the P@P app note AN1204 and the MiWi app note AN1371.

Blogger

Can you control Transmit power

Iron

@FrankMcCarthy

You must also enable security in the ConfigApp.h file, which you can configure using Wireless Development Studio's configuration option.

Blogger

?? If a person walks between the nodes, does that interfere with line of sight?

Gold

@78RPM

Recall the PICDEM Z in the Tools area.  The code is loaded onto a PIC micro.  The PIC uses SPI to talk to the radio module.

Blogger

@JDBC

Range for MA module 30 to 90 feet.  MB radio 4000 feet.  These are line of sight distances.

Blogger

Thanks again Lauren and Fred

Iron

Thanks Fred & Lauren.

Iron

?? Fred, Does sub-MHz band offer greater range and immunity to barriers like people and other animals? How much more range can I get with sub-MHz?  Does it have to be line of sight?

Gold

?? Fred - How much more complex is the MiWi Pro to implement compared to P2P & how much memory is required to hold the stack?

Iron

?? Fred, if you want to use encryption in the MiApp_UnicastConnection call on p19, is there any other setup required other than setting the second parameter to TRUE?

What kind of encryption is used?

 

@Alaskaman66

You must decide which band you want to  operate in. There are 3 radio madule families - 2.4GHz, 868MHz and 915MHz

Blogger

?? Fred, regarding the examples of C source code: Where does the object code get loaded? Does it reside on the Zena or on an external microcontroller (whether that be a PIC or Arduino).  I have been using XBee and sending API codes to another XBee requires an external MCU.

Gold

Excellent presentation!

Good introduction to MiWi. Thanks.

Iron

Are multi-band radio modules available for MiWi, or do you have to decide on a specific band first?

Audio was fine in Firefox

Thank you, Fred and Lauren

Iron

Nice job Fred, you covered the material extremely well

Iron

Thanks, good presentation.

Iron

Thank you very much!

Iron

Thanks Fred and Lauren.

Iron

Thanks Fred. Love the examples.

Iron

Another good session Fred. I like the pace of the course.

Iron

Thanks for the introduction to MiWi.

Iron

Excellent content, see you tomorrow

Iron

Thank you, Fred and Lauren

Iron

Many thanks Fred and Lauren

Iron

Thank you Fred, Lauren, and Digi-Key

Gold

I use Chrome.  Works fine.

Iron

We are on slide 21. 

Platinum

Had problem with IE, switched to chrome working better now.

Iron

Maybe Lauren has a more direct source of audio and is leading the general web feed buffering.

 

audio sync fine here with firefox

Iron

I think we are on slide 19

Try chrome for audio prob

Iron

I have some problem with aduo as well

 

Iron

Slide 17 on my audio now

We are on slide 20. 

Platinum

My audio stream is out of sync with the text/chat slide declarations

We are on slide 18. 

Platinum

We are on slide 17. 

Platinum

We are on slide 16. 

Platinum

interested to know more about it.

Iron

zigbee can run like  module as well as MiWi

Iron

Interesting, but not at this time

Iron

Perhaps I missed this in the presentation yesterday, but what kind of range (distance in feet) does MiWi support in open area?

Iron

I am interested in MiWi to konw  more about it

Iron

I might need mesh to get desired range & would need MiWi Pro

Iron

We are on slide 13. 

Platinum

Will consider since Zigbee stack can be run on the module as well as MiWi

No upcoming project on MiWi

Iron

I need mesh networking

Gold

I am interested in MiWi since I do not think I need hopping since area is small.  But, there is a large potential for interference so I am interested in how it compares in plant environment.

Iron

We are on slide 12. 

Platinum

Perhaps... I've used MiWi Pro Mesh in projects in the past

Iron

Will definitely consider

 

Iron

No upcoming projects planned at this time. Here to learn.

 

Iron

Not really - vendor lockin...

Iron

We are on slide 11. 

Platinum

The question was: Is MiWi P2P a good fit for one of your upcoming projects? 

Platinum

We are on slide 10. 

Platinum

I would use modules.  Last time I took an intentional radiator through FCC certs it cost about $10K.

Iron

only doing research at the moment, no design in mind yet.

 

Iron

No MRF24J40 based radio module

Iron

I have to know more about MiWi to determine which to use

Iron

I have been looking at MiWi for a proprietary application to avoid having to deal with the ZigBee Alliance.

Iron

No, will use off the self module

implement ZigBee? not sure yet

Iron

No, still probably MiWi

 

The question was: Are you considering rolling your own MRF24J40-based radio module? 

Platinum

Don't know yet.  Depends on future needs.

Iron

Yes, still going with ZigBee

 

Iron

The question was: Now that you've been introduced to MiWi, do you still plan to implement a ZigBee network? 

Platinum

Hello from Coventry

 

Iron

Hi all -Audio is live! If you don't see the audio bar at the top of the screen, please refresh your browser. It may take a couple tries. When you see the audio bar, hit the play button. If you experience audio interruptions and are using IE, try using FF or Chrome as your browser. Many people experience issues with IE. Also, make sure your flash player is updated with the current version. Some companies block live audio streams, so if that is the case for your company, the class will be archived on this page immediately following the class and you can listen then. People don't experience any issues with the audio for the archived version.

Good morning from Austin, TX

Iron

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.
