Yes, you can use Smart Hospital on localhost installation (using XAMPP or WAMP) and access it in your local LAN (Local Area Network) from another PC in the network. How to configure Smart Hospital local LAN network.
Configure Smart Hospital To Use In Local LAN Network
If you have hosted Smart Hospital on your local server and want to use it in the local LAN (Local Area Network) network then your Smart Hospital hosting machine should have a static IP address (not be dynamically assigned by your modem DHCP). Here suppose your server hosting machine has IP address 192.168.1.2 then when you are installing Smart Hospital you should type 192.168.1.2/myhospital/ not localhost/myhospital/ in the browser address bar otherwise you cannot access Smart Hospital from other computers in your LAN and will redirect to localhost/myhospital/url
If you have already installed Smart Hospital using localhost/hospital/ then you can correct this by editing the base_url value in file /application/config/config.php. In this file change localhost to your hosting server's static IP address like 192.168.1.2.
