Consider the following situation. I have several non-PC devices (e.g. robots & network cameras) and a PC on a wired network. The non-PC devices have an ethernet port and I plug LAN cables between them and the switch.

Normal wireless adapters come as USB sticks which you connect to the PC. So, is there a wireless adapter (battery powered) which I can plug into the ethernet port of my non-PC device which connects to a wireless router?

Are the robots and cameras Industrial devices like Fanuc robots or Cognex cameras? – Dave M Mar 3 '11 at 20:53
@DaveM: Close. We're using JAI cameras. – Jacob Mar 3 '11 at 22:05
Can you explain the application in a bit more detail? Is the robot battery powered as well? How long a run time do you need? – Dave M Mar 4 '11 at 15:50
@DaveM: None of the applications are battery powered and are used for several hours. It's OK if the "adapter" needs to connected to a power source. – Jacob Mar 5 '11 at 17:26

I didn't really enjoy EE classes, but I found an interesting discussion here that seems to boil down to this being somewhat unfeasible due to the power draw:

I looked at a couple of Access Points and 6 watts was about the lowest power that I saw. That was 12 v @ 500 ma. The "big" 9v batteries are 1100 mah, so they would last a little over 2 hours at that drain.

True, it is technically a wireless bridge "bridging" multiple networks of one device. – Jacob Mar 3 '11 at 22:12
I was disappointed, because I'd have a use or two for this, myself. ;) – Kara Marfia Mar 4 '11 at 1:13
I still think a bridge can be used for this application. Of course, it's quite expensive and most of the bridges I saw online have a minimum of 2 ports when I'd like just one (i.e. one for each device). In any case, it's too expensive. – Jacob Mar 5 '11 at 17:27

My associate who is the robotics expert suggests Phoenix Contact
