I know wgb is used as wireless client to extend connectivity to wired end devices. However, can someone please help me understand the difference between
a normal ap & wgb(after it is converted to wgb from an ap), in terms of connectivity & signal coverage.
Can we substitute a normal AP in place of wgb if there is a need to connect a thermal scanner to this wgb or ap and the connections needs to work over the wireless network.
If the requirement is to extend the coverage to a location where wired users will be connected, can a WGB be used.
Yes, this is the functionality of WGB. See below post topology is what you are trying to achieve. If it is, you are ok with that.
Is this feasible or we need to have a normal AP(non-WGB) for such a scenario. The users in this location might also connect themselves via wireless at times.
As WGB is typically act as a client, it does not provide wireless coverage expansion (or acting as AP). So you need to have normal AP wireless coverage in the area to wireless client to join (including WGB itself)
Hope this clear, if not let me know

Assuming you will use WGB in your Unified Wireless Environment (without connecting it to another autonomous AP)
WGB will not consume any AP licence of your controller as it will connect to a Lightweight Access point managed by your WLC. There is no direct communication between WLC & WGB.
WGB(client) <====> LAP < ==== > SW <====> WLC
Wired clients sitting behind WGB will appear under client list (Monitor -> Clients) of your WLC & appear them as a WGB clients (ie "WGB=Yes")
