Thanks Alex and Marty.

Blogger

thank you for your time guys :)

Iron

Thanks so much for your time, Marty. Listeners, the chat will be available on archive.

Oh, I meant most of the time, customers that requested for a enclosed wireless system... where are the majority request coming from based on your data? Green or brownfield?

Iron

Site surveys are important so that you understand your current environement

Iron

When using Zigbee or bluetooth enbabled device these too can be affected by certain interferences

Iron

Greenfield you have more control over implementation Brownfield you need to work within your current environment.

Iron

Environement has an impact on the decision open frequenncy ranges like 900mghz open the door to interference more too follow

Iron

Marty, between greenfield & brownfield; if an enclosed wireless system (not 802.11) were to deploy, which field to your experience has the highest acceptance rate to accept wireless systems into their industrial environment? Why?

Iron

802.11a used becasue lnot many devices like laptops operate at this level.

Iron

Marty, can you give a few of your prescriptive points of how to approach a wireless build out?

Blogger

Additional answer to cgervasi although DFS channels may be available customers have found it better to not bother or stay way becasue sometimes if your are near an airport thsi can be a cause a conflict

Iron

Wireless Hart is becoming more common in process instrumentation andh most ofter we see 802.11a being used for factory automation

Iron

What do protocols like WirelessHART add on top of 802.11?  Which protocols are most often used in factory automation, and why?

I ask b/c I've worked on wireless equipment in the past.  The DFS channels are tricky because you have to vacate them for a period of time if you detect radar.  I never found an easy way to get all nodes off a channel when one unit detects radar and then to get them back to that channel once the silent period expired.  I imagine someone will come up with a good way to do it eventually, esp as the other 5GHz channels get crowded.

Iron

Additional answer to DFS question wireless hardware should be able to scan to find the best available channel for communication

Iron

Based on certain country codes technology built into the wireless hardware will accomplish this

Iron

medical devices 100% will have wireless BLE in near future

Additionaly sercurity will alsways be a concernt in the future of wireless

Iron

Oh, I'm getting a delay in the chat.  My only question was whether the so-called DFS channels are usable?  Can equipment intelligently choose another channel when radar is detected and perhaps move back when radar is gone?

Iron

There may come a time where wireless is the first option or only option based on its reliability and maturity of the technology

Iron

Where do you see wireless applications going in the future? What are some of the upcoming promises with this technology?

Blogger

Is the presentation over?

Iron

Please ask Marty your questions now.

Blogger

Companies that provide Industrial Products include Siemens, Hirscmann and Phoenix Contact. Similar to some of the consumer products most can be set up using the build in web browser

Iron

What "industrial" wireless hardware is most popular? Easiest to setup and integrate?

Iron

I wonder if there is any way to use channels in the "DFS" (radar-detection required) bands can be used reliably.  They're clearer, but you have to be prepared to vacate them as soon as you hear any radar signals. 

Iron

Marty will be joining the live chat stream in 5min

Blogger

Rob, IMHO it's easier to do DoS attack.  My impression, though, is that AES encryption is really as good as wired.  No one wants to say it's "wired equivalent" since an easy crack was found for a scheme by that name.

Iron

Is wireless easer to hack than wired?

Blogger

Could someone send me a powerpoint or the text of the presentation since I can not get it now?  Or can I log in at another time with a different broswer and replay the presentation?

Iron

@ALL:If you're having trouble with the audio, please try refreshing your browser

in design news radio box it shows buffering

Iron

Can Marty speak about the status of wireless engine sensors for the automotive industry?

Iron

The radio bar is just sitting there buffering

Iron

IT blocks our media stream too, so we can not view in our company.

i am not seeing or hearing anything

Iron

Using firefox-no audio or video player

 

Iron

Blogger

Am i to see video stream and audio, I get nothing

 

Reload your browser if no player

Blogger

listeners pls seed questions here for Marty aand I will ask him

Blogger

My IT oruganization blocks streaming media - no player here either

 

Iron

No audio player has appeared on my screen...

 

Iron
