to my knowledge, there are no wireless zero clients currently
To my knowledge as well, there are not many if any Zero clients that support build in Wireless.
Rather easily however, you can buy a wireless bridge (Netgear makes a good one) that can allow Wireless capabilties on Zero clients. Thats how we facilitate this in our company.
Could you please let me know what model device you are using for this purpose? Most that I have found are large and would not easily fit on a mobile cart.
Thanks.
I am using some Linksys WET610N for our mobile Polycom carts, and they work great.
