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?
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
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.
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?
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.
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.
At IMTS last week, Stratasys introduced two new multi-materials PolyJet 3D printers, plus a new UV-resistant material for its FDM production 3D printers. They can be used in making jigs and fixtures, as well as prototypes and small runs of production parts.
In a line of ultra-futuristic projects, DARPA is developing a brain microchip that will help heal the bodies and minds of soldiers. A final product is far off, but preliminary chips are already being tested.
