[Asterisk-Users] WiFi IP Phones

[Anton Krall]

Dean. I think We are starting the other way around on this. First We need to
find if there are such SIP Phones out there and look at specs then I can go
to my client and ask all these questions you just listed. 

No use asking all of these questions if there aren't any such phones out
there to start with. The client specifically requested wifi sip phones.

|Anton, did you even read my post?
|
|If you don't know what you are doing then you don't deserve to 
|be a distributor in this space.
|
|How are you going to isolate the access points?
|What rating zones will you need to meet?
|What existing arrestors are in place? (gas, fibre, etc)
|
|In addition, what ranges are they expecting from the access points?
|What physical environments are the signals going to be 
|operating in? (steel etc) What 2.4 ghz interference can be 
|expected from other emitting industrial equipment.
|What physical environment issues need to be considered 
|condensation, salination, operating temps etc.
|Will these wifi handsets be a workers only form of 
|communication or is there a backup dead mans pager/radio alert 
|systems (occupational health and safety issues etc)
|
|There's a reason why intrinsic costs money and it's got a lot 
|more to do with safety than will the satellite signal work well.
|
|Cheers,
|Dean
