We are a HVAC OEM/VAR supplier. We typically install our controls on a standard IP Lan with standard CAT-5 connections. These controls may be in a client/server configuration where there is Server software running on a central PC (termed the Head-End) and client software running in each of the control devices (the control devices are essentially embedded PC’s that may or may not be running a Windows operating system, or a Unix derivative real time operating system). At times the controls devices may be installed without the server in a Peer to Peer configuration.
Often we are on-site to do installations and check out before the permanent site Lan is in place thus we will typically run a temporary network to support our efforts. My question is: can we use two or more WiFi access points, one for each control device, in place of wired connections. These ‘temporary’ set ups typically do not include a Router or Gateway to manage traffic, but may very well include Switching Hubs.
Seems like a fairly fundamental and straight forward solution, but I am unsure of the need of a Router or Gateway…
