I have a prospect who is planning on implementing RMS on a 3-register system, but does not want to use a regular Ethernet wired network in their store (small space, and don't want to have to run wires); they want to operate using a wireless router and each register connected using USB wireless adapters.
I am VERY leery about using RMS on a wireless network. RMS gets really cranky if it loses it's network / database connection for even a moment. The POS application will switch over to offline mode, but it can be a hassle to know when that's happened and to recover from it. Also, Store Ops Manager does not have a offline mode, so you can't work disconnected from the main RMS database and sync up later. I'm worried that they could be in the middle of entering information, drop the wireless connection, and lose what they've entered but haven't saved yet.
I would be very curious to know other people's experiences with using RMS on a wireless network as a full-time implementation.
